  • Stinging hairs on the Japanese nettle Urtica thunbergiana have a defensive function against mammalian but not insect herbivores

    Misaki Iwamoto; Chika Horikawa; Megumi Shikata; Naoko Wasaka; Teiko Kato; Hiroaki Sato

    Thorns and hairs of plants can serve as defenses against herbivores, although they may not have evolved under selection by herbivory. Japanese nettles, Urtica thunbergiana, in Nara Park, Nara Prefecture, Japan, where sika deer have been protected for 1200 years, bear many more stinging hairs than those in areas with few or no deer. Previous studies suggested that such hairy nettles evolved under natural selection imposed by intense deer browsing, because stinging hairs deterred deer browsing and because among-population variation in hair density was associated with deer abundance. To confirm this hypothesis, we examined (1) whether stinging hairs affected oviposition and feeding preferences of herbivorous insects and (2) the degree to which they deterred deer via laboratory and field experiments with hairy nettles from Nara Park and with almost-hairless nettles from another area. A specialist butterfly, Indian red admiral, showed no oviposition or larval feeding preferences for either hairy or hairless nettles. Insect damage levels did not significantly differ between the two variants. In contrast, deer browsed hairless nettles more heavily than hairy ones. In hairy nettles, however, the level of deer browsing was not proportional to stinging-hair density, presumably because the hairy nettle population had reached a plateau for resistance as a result of long-term strong directional selection for stinging hairs. These results corroborate the hypothesis that hairy nettles in Nara Park evolved through natural selection under intense deer browsing. © 2014 The Ecological Society of Japan., Springer-Verlag Tokyo, 2014, Ecological Research, 29 (3), 455 - 462, doi

  • Among-population variation in resistance traits of a nettle and its relationship with deer habitat use frequency

    Megumi Shikata; Teiko Kato; Ei'ich Shibata; Hiroaki Sato

    Because leaf hairs serve as resistance against herbivores, among-population variation in hair production may arise from adaptation to local herbivore communities. It is possible that Japanese nettle (Urtica thunbergiana) shows among-population variation in stinging hair abundance that is associated with the frequency of habitat use by sika deer (Cervus nippon). We examined 31-32 individuals of each of 19 populations for leaf area, stinging hair number (/leaf) and stinging hair density (per square centimeter) in and away from Nara Park (6.6 km2), where many deer have been protected for 1,200 years. At each site we also measured deer habitat use frequency, light intensity and soil fertility as environmental factors potentially affecting leaf traits. We analyzed our hierarchical data at the levels of individuals and populations using multilevel structural equation modeling. Leaf area had a positive direct effect on stinging hair number at the individual level but no significant effect at the population level. At the population level, deer habitat use frequency had a negative direct effect on leaf area and positive direct effects on stinging hair number and density, generating a negative indirect correlation between leaf area and stinging hair number. Light intensity had a negative direct effect on leaf area, while soil fertility had no significant effect on any trait. These results suggest that the relationships between leaf area and stinging hair number at the two levels do not align. We discussed what processes were involved in the effects of environmental factors on leaf traits. © 2012 The Ecological Society of Japan., 2013, Ecological Research, 28 (2), 207 - 216, doi

  • Early Leaf Abscission Has Little Effect on Larval Mortality of Ectoedemia cerviparadisicola (Lepidoptera, Nepticulidae) Associated With Quercus gilva

    Yukari Shinozaki; Ayaka Yamamoto; Masako Oishi; Hiroaki Sato

    There has been an argument as to whether early leaf abscission substantially affects larval mortality of leafminers because of leaf senescence. Recently, a study reported that leaf abscission considerably increased the mortality of a leafminer (Ectoedemia cerviparadisicola Sato, sp. nov.) associated with Quercus gilva (Blume) in Nara Park, central Japan, where sika deer (Cervus nippon (Temminck)) have been protected for 1,200 yr, because deer consumed many abscised leaves containing living larvae. The study, however, did not investigate the life history of the leafminer or survey the leaf-fall pattern of Q. gilva through the season, so that it failed to quantify larval mortality because of deer predation. To test whether deer have a substantial effect on larval mortality of this leafminer, we regularly collected abscised and nonabscised leaves of Q. gilva through the season, examining mines and larvae in those leaves. Over 90% of mined leaves abscised in the period of peak leaf fall, when almost all larvae had already emerged from mines to pupate. Most dead larvae in abscised leaves were judged to have already died at the time of abscission from their instars and body features. The proportion of living larvae in abscised leaves was estimated to be <1.8%. Thus, even when deer preyed upon all living larvae in abscised leaves, they would hardly contribute to the increase in larval mortality. These results indicate that the effect of leaf abscission on leafminer mortality via deer predation and other causes is limited. The leafminer was described as new to science in the Appendix., ENTOMOLOGICAL SOC AMER, Jul. 2012, ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA, 105 (4), 572 - 581, doi;web_of_science

  • Differences in leafminer (Phyllonorycter, Gracillariidae, Lepidoptera) and aphid (Tuberculatus, Aphididae, Hemiptera) composition among Quercus dentata, Q. crispula, Q. serrata, and their hybrids

    Leafminer (Phyllonorycter, Gracillariidae, Lepidoptera) and aphid (Tuberculatus, Aphididae, Hemiptera) composition were studied in three deciduous oak species, Quercus dentata, Q. crispula, and Q. serrata, and their hybrids in Tomakomai Experimental Forest of Hokkaido University, Hokkaido, northern Japan. Identification of trees in this forest was done mainly on the basis of discriminant analysis on leaf morphology with reference to trees in pure Q. dentata and Q. crispula stands and a Q. serrata stand mixed with Q. crispula. The results suggested that hybridization occurred in all combinations (i.e. Q. dentata-Q. crispula, Q. crispula-Q. serrata, and Q. serrata-Q. dentata) and the frequency of hybrids was approximately 10%. The composition of Phyllonorycter and Tuberculatus species differed between Q. dentata and Q. crispula or Q. serrata, but did not differ between Q. crispula and Q. serrata. Thus, Q. dentata could differ from Q. crispula and Q. serrata in chemical properties that determine herbivore host selection, survival, and performance, possibly reflecting eco-physiological differences or phylogenetic distances. The study insects were divided into three groups: species specialized to Q. dentata (three Phyllonorycter and one Tuberculatus species), those to Q. crispula and Q. serrata (six Phyllonorycter and two Tuberculatus species), and a species collected at least from Q. dentata and Q. crispula (one Tuberculatus species). Putative hybrid trees of Q. dentata and Q. crispula harbored both Q. dentata-specific and Q. crispula-specific insects., SPRINGER TOKYO, Aug. 2011, JOURNAL OF FOREST RESEARCH, 16 (4), 309 - 318, doi;web_of_science

  • The evolution of nettle resistance to heavy deer browsing

    Teiko Kato; Kiyoshi Ishida; Hiroaki Sato

    We examined whether heavy browsing by sika deer, Cervus nippon Temminck, changed morphological characteristics of a Japanese nettle, Urtica thunbergiana Sieb. et Zucc., in Nara Park, where a large population of sika deer has been maintained for more than 1,200 years. Wild nettles of Nara Park exhibited smaller leaf area, 11-223 times more stinging hairs per leaf, and 58-630-times higher stinging hair densities than those of other areas where there was no evidence of sika deer browsing. There were no significant differences in stinging hair length between the areas. Nettles from Nara Park that were cultivated from seeds in a greenhouse retained a larger number and higher density of stinging hairs. In the field, nettles of Nara Park were less frequently browsed by sika deer and showed higher survivorship than nettles that were transplanted from an unbrowsed area into Nara Park. These results indicate that: (1) the U. thunbergiana population of Nara Park has an extremely high stinging hair density compared with those of unbrowsed areas; (2) this characteristic has a genetic basis, and (3) stinging hairs serve as a defensive structure against sika deer, contributing to an increase in survivorship. Thus, we conclude that a U. thunbergiana population in Nara Park, with extremely high stinging hair densities, has evolved through natural selection due to heavy browsing by sika deer., SPRINGER TOKYO, Mar. 2008, ECOLOGICAL RESEARCH, 23 (2), 339 - 345, doi;web_of_science

  • Application of fecal pellet group count to sika deer (Cervus nippon) population monitoring on Mt. Ohdaigahara, central Japan

    Roku Goda; Masaki Ando; Hiroaki Sato; Ei'Ichi Shibata

    The relationship between the number of fecal pellet groups found in line transects and estimates of deer density based on block counts on Mt. Ohdaigahara in central Japan was examined and the validity of fecal pellet group counts for obtaining an index of sika deer population density was assessed. Sika deer population densities estimated by block count were 13.0km2 in spring, 18.3km2 in summer and 19.0km2 in autumn. Fecal pellet group counts showed low positive correlations with deer density in spring and autumn (0.69 in spring and 0.68 in autumn), but not in summer, indicating that deer density may not be predictable then. We suggest that fecal pellet group count reflects deer density in spring or autumn, and might be feasible as an index of deer population density. © the Mammalogical Society of Japan., Sep. 2008, Mammal Study, 33 (3), 93 - 97, doi

  • Guild Structure and Coexistence Mechanisms in the Parasitoid Assemblage Associated with a Leafminer, Coptotriche japoniella (Lepidoptera, Tischeriidae), on an Evergreen Tree, Eurya japonica (Theaceae)

    Masako Oishi; Hiroaki Sato

    The parasitoid assemblage associated with it lepidopteran leafminer, Coptotriche Japoniella (Tischeriidae), on an evergreen tree, Eurya Japonica (Theaceae), was studied in the center of Japan to explore parasitoid coexistence mechanisms. The leafminer supported 12 parasitoid species. Eight abundant or common species were classified into five guilds according to their koinobiont/idiobiont mode and host-instar utilization pattern: early larval koinobiont, mid-larval idiobiont, mid-larval-late idiobiont, late larval-pupal idiobiont, and pupal idiobiont. The early larval koinobiont (Orgilus Kunatai) and mid-larval idiobiont (Achrysocharoides sp.) seemed to be specialized on the host, whereas the members of the other guilds had a wide host range. The mid-larval-late larval (Cirrospilus diallus and Pnigalio sp.) or late larval-pupal idiobionts (Chrysocharis albipes, Apleurotropis kumatai, and Pleurotroppopsis japonica) facultatively hyperparasitized half of spinning larvae or pupae of the early larval koinobiont. These results suggest that parasitoid coexistence in this assemblage is greatly promoted by high levels of facultative hyperparasitism by idiobiouts with wide host ranges on the dominant koinobiont., ENTOMOLOGICAL SOC AMER, Oct. 2008, ENVIRONMENTAL ENTOMOLOGY, 37 (5), 1231 - 1240, web_of_science

  • Population dynamics of leafminers on a deciduous oak Quercus dentata

    Takashi Nakamura; Kouhei Hattori; Takahide A. Ishida; Hiroaki Sato; Masahito T. Kimura

    Population dynamics of leafminers on a deciduous oak Quercus dentata, were studied for 9 years in northern Japan. Most leafminers in the study site were bivoltine, while a gregarious Stigmella species was univoltine. Many leafminers showed species-specific patterns of population fluctuations. in the major bivoltine leafminers (Phyllonorycter, solitary Stigmella and Caloptilia species), the densities of autumn generation mines were highly correlated with those of summer generation mines when analysed on the basis of the densities at the early developmental stage. Thus, their mortality and egg productivity in this phase (i.e., from late June to early September) varied only a little from year to year. In Phyllonorycter, however, correlation of densities between these two generations became lower when analysed on the basis of the densities at the tissue-feeding stage, suggesting that their mortality from the early developmental stage to the tissue-feeding stage in the autumn generation varied from year to year. Regression analyses suggest that yearly variation in precipitation in July and August was responsible for this variation. Correlations of densities between the autumn generation and the summer generation of the next year in the major leafminers were not high. Thus, their mortality and/or egg productivity in this phase (i.e., from September to June of the next year) varied from year to year. Regression analyses suggest that climatic factors that affected the population dynamics in this phase varied among the leafminers, except some factors have been suggested to be commonly effective in the two Phyllonorycter species. Density-dependent effects were not explicit in the population dynamics of the present leafminers.

  • Group size of feeding stream case-bearing caddisfly grazers and resource abundance

    Izumi Katano; Hiromune Mitsuhashi; Yu Isobe; Hiroaki Sato; Tadashi Oishi

    Several herbivorous insects are known to benefit from feeding in groups; however, little is known about (1) the resource conditions under which herbivorous insects perform group feeding and (2) the optimum population size to get any benefits by group feeding, for example, in terms of growth performance. To test the hypotheses that the benefits from group feeding change with resource level and population size, we performed field investigations and an enclosure experiment using the grazer caddisfly larva Micrasema quadriloba. The field investigations revealed aggregated distributions of larvae (indicator of aggregation, 1(delta) = 4.1 +/- 1.55, aggregated density: 12.7 +/- 5.3 individuals per 3.1 x 3.1 cm(2) (mean +/- 1 SD) when periphyton was abundant on stream cobbles and random distributions (I-delta = 1.0 +/- 0.11) when periphyton was scarce. In the enclosure experiment, the relative-growth rate (RGR) of the larvae at each population size showed different tendencies at high and low periphyton abundance Levels; RGR with abundant periphyton had a convex curve with a peak at intermediate population size, whereas RGR with scarce periphyton decreased linearly with increasing population size. The benefits from group feeding thus changed with resource level; larvae obtained high growth performance by group feeding behavior only when the resource was sufficiently abundant. The present study revealed not only that the optimum group size of larvae increased their growth performance, but also that this optimum group size occurred frequently in the field. We also discuss the mechanisms and benefits of group feeding by case-bearing caddisfly grazers. (C) 2006 Gesellschaft fur Okologie. Published by Elsevier GmbH.

  • Among-tree variation in leaf traits and herbivore attacks in a deciduous oak, Quercus dentata

    Masashi Kitamura; Takashi Nakamura; Kouhei Hattori; Takahide A. Ishida; Satoshi Shibata; Hiroaki Sato; Masahito T. Kimura

    Variations in defensive and some other leaf traits were studied in a population of an oak species, Quercus dentata Thunberg, in northern Japan, with reference to attacks by ectophagous herbivores and leafminers. The oak population showed substantial individual variations in concentrations of total phenolics and condensed tannins, nitrogen content, trichome density, leaf area and budburst timing. With the exception of leaf mass per area, which showed a positive relation with leaf toughness and a negative relation with water content, no significant relation was observed between the plant traits studied, suggesting an absence of trade-off or linkage between them. The oaks also showed substantial individual variations in leaf area loss by ectophagous herbivores, densities of major leafminers (Phyllonorycter and Stigmella species) and survival of Phyllonorycter sap-feeding larvae. The density of trichomes showed a significant, negative relation with leaf area loss by ectophagous herbivores, but significant, positive relations with densities of some leafminers. The other leaf traits seldom showed significant relations with herbivore densities or survival. In this oak population, these traits may not have enough variations to be reflected in the abundance and performance of herbivores., TAYLOR & FRANCIS AS, 2007, SCANDINAVIAN JOURNAL OF FOREST RESEARCH, 22 (3), 211 - 218, doi;web_of_science

  • Inhibition of premature leaf abscission by a leafminer and its adaptive significance

    Masako Oishi; Hiroaki Sato

    We tested the possibility that a lepidopteran leafminer, Coptotriche japoniella Puplesis and Diskus, inhibits the host plant Eurya japonica Thunberg from abscising mined leaves prematurely to increase its survivorship in immature stage. We monitored abscission patterns of mined leaves with sacrificed larvae, mined leaves with living larvae, and unmined leaves from April to July 2004 and 2005 until leafminers emerged as adults. Unmined leaves rarely abscised before July. Mined leaves with sacrificed larvae fell at a constant rate after May, abscising significantly more than unmined leaves. In contrast, mined leaves with living larvae rarely fell before adult emergence; afterward they abscised rapidly. We also examined larval/pupal survivorship and mortalitv sources on the ground and trees after leafminers completed larval development. Leafminers on the ground suffered a higher mortality from predation than those on trees, and thus they emerged as adults on the ground less successfully. These findings suggest that the leafminer C. japoniella prevents the host plant front abscising mined leaves prematurely until adult emergence, thereby increasing their survivorship., ENTOMOLOGICAL SOC AMER, Dec. 2007, ENVIRONMENTAL ENTOMOLOGY, 36 (6), 1504 - 1511, web_of_science

  • Japanese oak silkmoth feeding preference for and performance on upper-crown and lower-crown leaves

    M Oishi; T Yokota; N Teramoto; H Sato

    We quantified differences in leaf traits between upper and lower crowns of a deciduous oak, Quercus acutissima, and examined feeding preference, consumption and performance of the Japanese oak silkmoth, Antheraea yamamai, for those leaves. Upper-crown leaves had significantly smaller area, larger dry mass per area, greater thickness, lower water content, higher nitrogen content and a higher N/C ratio than lower-crown leaves. When simultaneously offered upper-crown and lower-crown leaves, moth larvae consumed a significantly larger amount of the former. However, when fed with either upper-crown or lower-crown leaves (no choice), they consumed a significantly larger amount of the latter. Female larvae reared on upper-crown leaves had a significantly smaller fresh weight, but attained a significantly larger pupal fresh and dry weight, with a significantly higher relative growth rate than those on lower-crown leaves. Although, like female larvae, male larvae had a significantly smaller fresh weight when reared on upper-crown leaves, they had a significantly larger value only for pupal dry weight. These results suggest that: (i) larvae ingest a greater amount of lower-crown leaves to compensate for the lower nitrogen content of the foliage, resulting in having an excess of water because of the higher water content of the foliage; (ii) feeding preference for upper-crown leaves accords with better performance (with respect to dry pupal weight and relative growth rate) on the foliage; (iii) better performance is explained by a higher nitrogen content and N/C ratio of the upper-crown foliage; and (iv) the effects of leaf quality on performance differ between sexes., BLACKWELL PUBLISHING, Jun. 2006, ENTOMOLOGICAL SCIENCE, 9 (2), 161 - 169, doi;web_of_science

  • Diversity of dung-beetle community in declining Japanese subalpine forest caused by an increasing sika deer population

    N Kanda; T Yokota; E Shibata; H Sato

    The Ohdaigahara subalpine plateau in Japan has recently suffered a reduction in primary forest land caused by an increasing population of sika deer (Cervus nippon). Deer have debarked many trees, causing die-back, gradually changing the primary forest first to light forest with a floor that is densely covered with sasa grass (Sasa nipponica) and then to S. nipponica grassland. To examine the effects of vegetative transformation on the dung-beetle community, we compared the diversity and abundance of dung-beetle assemblages in the primary forest, transition forest, and S. nipponica grassland using dung-baited pitfall traps. The species richness and species diversity (Shannon-Wiener index) were significantly highest in the primary forest and lowest in the S. nipponica grassland. The evenness (Smith-Wilson index) was highest in the primary forest and nearly equal in the transition forest and S. nipponica grassland. The abundance was apparently greater in the transition forest than in the primary forest and S. nipponica grassland. These results suggest that loss of primary forest resulting from an increasing deer population decreases the diversity of the dung-beetle community while increasing the abundance of dung beetles in the transition forest. Sika deer use transition forests and grasslands more frequently than primary forests as habitat, but an increase in dung supply there does not necessarily increase the diversity or abundance of dung-beetle assemblages., SPRINGER TOKYO, Mar. 2005, ECOLOGICAL RESEARCH, 20 (2), 135 - 141, doi;web_of_science

  • A new mutation in the timing of autogamy in Paramecium tetraurelia

    R Komori; H Sato; T Harumoto; Y Takagi

    We have isolated a new type of Paramecium tetraurelia mutant, named rie-2, that has a long immaturity period until autogamy. We previously isolated such an autogamy mutant, designated rie-1. These two mutants had some additional common features such as dependence of the occurrence of autogamy on the temperature, involvement of a single recessive gene, lower fission rate and shorter clonal life span. However, rie-2 was considered a new type mutant distinguishable from rie-1 because of their different natures of temperature sensitivity. First, the temperature at which they resembled the wild-type phenotype was low (19 C) in rie-2, although it was high (32 &DEG; C) in rie-1. Second, the clonal life span of rie-2 at 25 &DEG; C was similar to that of the wild-type, but it was extremely shorter at 32 &DEG; C than at 25 &DEG; C, although it was similarly shorter at both temperatures in rie-1. Third, the difference of the fission rate between mutant and wild-type was greater at 32 &DEG; C than at 25 &DEG; C in rie-2, although it was similar at both temperatures in rie-1. This report shows that a gene mutation to elongate the period until sexual maturation does not necessarily assure the long life span. © 2005 Elsevier Ireland Ltd.

  • Reach-scale distribution dynamics of a grazing stream insect, Micrasema quadriloba Martynov (Brachycentridae, Trichoptera), in relation to current velocity and periphyton abundance

    Katano, I; H Mitsuhashi; Y Isobe; H Sato; T Oishi

    Reach-scale temporal shifts in the distribution of larvae of a grazing caddisfly, Micrasema quadriloba (Brachycentridae), were investigated in a Japanese mountain stream. The larvae showed an aggregated distribution within the reach at the beginning of the immigration, then became randomly dispersed throughout the reach as the immigration progressed. The abundance of periphyton in the reach decreased dramatically with increasing dispersal of the larvae. Simple regression analyses revealed that the stream's flow regime was the most important environmental factor that determined the reach-scale distribution of the larvae and that the relationship between the flow regime and the distribution of the larvae shifted temporally. In addition, our results suggest that only this species of grazing insect, which was dominant in the study reach, controlled the reach-scale abundance of the periphyton., ZOOLOGICAL SOC JAPAN, Aug. 2005, ZOOLOGICAL SCIENCE, 22 (8), 853 - 860, doi;web_of_science

  • Differentiation and hybridization between Quercus crispula and Q-dentata (Fagaceae): Insights from morphological traits, amplified fragment length polymorphism markers, and leafminer composition

    TA Ishida; K Hattori; H Sato; MT Kimura

    Quercus crispida and Q. dentata (Fagaceae) are dominant members of cool-temperate forests of Japan and are assumed to hybridize in nature. To characterize and discriminate these two species and their hybrids, we carried out multivariate analysis using several morphological traits and principal coordinate analysis using molecular (amplified fragment length polymorphism [AFLP]) data. Further, we examined the composition of Phyllonorycter species (leafmining insects) on individuals from a mixed forest. Morphological traits and Phyllonorycter composition differ enough in these two oak species to be useful for identification of species and hybrids. AFLP data, however, are less informative because the degree of molecular differentiation between the two species is low. Nine out of 105 individuals from a mixed stand had intermediate morphologies according to the multivariate analysis, and eight out of the nine individuals had intermediate Phyllonorycter composition in either one or both of the two study years. These eight individuals were tentatively assigned as hybrids or backcross individuals, and the remaining individual with intermediate morphologies was assigned as Q. dentata according to its Phyllonorycter composition and the AFLP analysis., BOTANICAL SOC AMER INC, May 2003, AMERICAN JOURNAL OF BOTANY, 90 (5), 769 - 776, web_of_science

    The pupal cremasters of twelve species of Japanese oak-feeding Phyllonorycter are examined. The cremasters, even those of closely related species, are specifically distinct. Combined with descriptions of European and North American species, the present results indicate that the cremaster can be used as a diagnostic character for the species of Phyllonorycter. A new species, P. persimilis, which was previously confused with P. similis Kumata, and the female of P. nipponicella (Issiki), hitherto unknown, are described. The nipponicella complex including these species is reviewed and the speciation of its members is discussed in relation to diversification of the host plant preference., APOLLO BOOKS, 2000, INSECT SYSTEMATICS & EVOLUTION, 31 (4), 387 - 400, web_of_science

  • Within-tree variation in density and survival of leafminers on oak Quercus dentata

    S Shibata; TA Ishida; F Soeya; N Morino; K Yoshida; H Sato; MT Kimura

    The density and survival of leafminers were examined on 50 sun leaves from each of 65 Quercus dentata Thunb, individuals in northern Japan in 1997 and 1998. Phyllonorycter (two species), Caloptilia tone species) and Stigmella (three species) were abundant or common on this oak in the study area. These leafminers appeared after mid-June, whereas most externally feeding caterpillars occurred from late May to early June when the water cont ent and nitrogen concentration of leaves were high. The density of these leafminers was about four times higher in 1998 than in 1997. A negative correlation was more often observed between mine density and leaf size, leaf wet weight per area or leaf toughness in the Phyllonorycter species, but the opposite correlation was more frequent for Caloptilia and Stigmella species. Conversely, no clear relation was observed between the survival of Phyllonorycter. larvae and leaf traits. In all leafminers except the gregarious Stigmella species, the mine density was more often positively correlated with leaf damage by chewing insects, and also the survival of Phyllonorycter larvae was often positively correlated with leaf damage. In the Phyllonorycter species, the survival of larvae tended to increase with the increase in density at the autumn generation. The correlation in the densities of mines between the summer and autumn generations was more frequently positive in the Pyllonorycter and Caloptilia species. In addition, the densities of different leafminers were often positively correlated. Thus, relations among leafminers, between leafminers and externally feeding caterpillars, and also between herbivores and host plants are complicated., BLACKWELL SCIENCE ASIA, Mar. 2001, ECOLOGICAL RESEARCH, 16 (1), 135 - 143, web_of_science

  • Payoffs of the two alternative nesting tactics in the African dung beetle, Scarabaeus catenatus

    H Sato

    1. Scarabaeus catenatus is a ball-rolling scarab in the subfamily Scarabaeinae. This species, however, makes use of two tactics for nest building: rolling and tunnelling. The tunnelling tactic differs substantially from the rolling tactic in that (1) it always involves repeated movements to and from the dung source and the nest, whereas rolling does not, and (2) it involves a shorter distance between the two sites. 2. Brood-nest founders were usually males and less often females, with about 25% adopting the rolling tactic and 75% adopting the tunnelling tactic. During nest building, the founder paired off with a scarab of the opposite sex, and they co-operated in the work. The female made one to four brood balls from the dung in the nest, each of which contained one egg. 3. Each scarab seemed to be able to employ both tactics. The tactic employed was independent of an individual's status, e.g. body size and timing of nest founding. 4. The rolling tactic offered only male founders a greater nest-defence success than the tunnelling tactic due to a lower intrusion into the rolled nest and a higher intensity of male-male fighting. The tunnelling tactic offered both male and female founders a larger number of brood balls than the rolling tactic because it enabled scarabs to take a larger amount of dung into the nest. 5. The reproductive success for the two tactics was estimated from the product of nest-defence success and the number of brood balls. As a result, the two tactics had equal fitness payoffs for males, but unequal payoffs for females. 6. The results suggest that male alternation of tactics is controlled by a mixed strategy. Female alternation, however, cannot be explained by mixed strategy, alternative strategies or conditional strategy., BLACKWELL SCIENCE LTD, Feb. 1998, ECOLOGICAL ENTOMOLOGY, 23 (1), 62 - 67, web_of_science

  • Male participation in nest building in the dung beetle Scarabaeus catenatus (Coleoptera : Scarabaeidae): Mating effort versus paternal effort

    H Sato

    The dung beetle, Scarabaeus catenatus, shows not only the rolling but also the tunneling tactic for nest building with bisexual cooperation. Sex roles, however, differed between the tactics. In rolling, the male rook the initiative like that of ball-roller species: he rolled a dung ball away and buried it. In tunneling, in contrast the male usually had a secondary role like that of tunnelers: he was less active in burrow excavation and provisioning. Regardless of the tactics, male participation did not increase female reproductive output measured by the number or size of brood balls in the field, but seemed to function as mate guarding against conspecific males. This suggests that, in both tactics, the male S. catenatus invests primarily in mating effort compared with paternal effort. The relative importance of mating effort in male participation seems to hold true in other dung beetles, irrespective of whether they are ball-roller or tunneler species. In addition, the male mating strategy of S. catenatus is compared with that of other ball-rollers., KLUWER ACADEMIC/PLENUM PUBL, Nov. 1998, JOURNAL OF INSECT BEHAVIOR, 11 (6), 833 - 843, web_of_science

  • Two nesting behaviours and life history of a subsocial African dung-rolling beetle, Scarabaeus catenatus (Coleoptera: Scarabaeidae)

    H Sato

    Nesting behaviour of a large-sized dung beetle, Scarabaeus catenatus (Gerstaecker), was observed at the Tsavo West National Park, south-eastern Kenya. Although this species is taxonomically a member of a dung-roller group (that is, subfamily Scarabaeinae), it had not only a rolling behaviour but also a tunneller behaviour for nesting. In the former case, the scarab rolled a chunk or a ball of dung some distance (0.5-15.5 m) away from the dung pat and buried it under the ground. In the latter case, it dug a tunnel near the dung pat (0-1 m) and transported several pieces of dung into the burrow. In both cases, brood nests were completed by a female alone or by male-female co-operation. Four days after dung burial, the female made one to four brood balls out of buried dung, in each of which she deposited an egg. On the other hand, the male left the nest soon after the female completed oviposition. Even after oviposition, the female stayed in the nest and cared for her progeny until they emerged. This indicates that S. catenatus is subsocial. A major source of offspring mortality was likely to be predation by driver ants (Dorylus sp.). Most females seemed to breed one time in each of two or more successive rainy seasons., TAYLOR & FRANCIS LTD, Mar. 1997, JOURNAL OF NATURAL HISTORY, 31 (3), 457 - 469, web_of_science

    Parasitoid assemblages associated with Phyllonorycter leaf miners (Lepidoptera: Gracillariidae) were examined on the 2 deciduous oaks, Quercus dentata and Q. mongolica, in Hokkaido, northern Japan, and those on 2 others, Q. acutissima and Q. variabilis, in Nara, central Japan. To address to what extent interspecific competition is important in organizing parasitoid communities, I compared species richness, species composition, and levels of parasitism by guilds at different host immature stages among the parasitoid assemblages. Parasitoids were separated into 5 guilds according to parasitism modes (idiobiosis and koinobiosis) and host immature stages attacked and killed. Pooled data showed that the number of parasitoid species per host leafminer species in Japan (3.1) was similar to that in the United Kingdom (4.1) and that idiobionts (potential generalists) exceeded koinobionts (specialists) in species number (62.5%). A koinobiont guild and 2 idiobiont guilds had an inverse relationship in level of parasitism between 2 assemblages at each study area. These results may suggest that interspecific competition is important in organizing parasitoid communities. Nevertheless, dominant species and guilds varied among the assemblages, resulting in different patterns of percentage of parasitism by guilds in relation to host stage among the assemblages. This implies underuse of hosts at some stages by parasitoids, and interspecific competition is unlikely to be severe. Interspecific competition, therefore, seems to partially contribute to parasitoid community organization., ENTOMOL SOC AMER, Aug. 1995, ENVIRONMENTAL ENTOMOLOGY, 24 (4), 879 - 888, web_of_science

    Life cycles of the two saddle-case making caddisflies, Glossosoma inops (Tsuda) and Agapetus yasensis (Tsuda) (Trichoptera, Glossosomatidae), were studied in Akadani Stream, Kii Peninsula, southern Honshu, Japan. Larvae of G. inops occurred chiefly in the mainstream, while those of A. yasensis were restricted to a hillside tributary. Agapetus yasensis was univoltine. This species grew slowly from late August through March, overwintered in the third and fourth instars, and pupae occurred from late April to early August. On the other hand, G. inops seemed to be a trivoltine species which produces a partial third generation in summer: certain part of cohorts which hatched in July grew rapidly and emerged in late August, while the rest of them grew slowly and emerged in late November. The summer generation exhibited the smallest size at third to fifth instar larvae among the three generations., SWETS ZEITLINGER PUBLISHERS, Apr. 1994, AQUATIC INSECTS, 16 (2), 65 - 74, web_of_science

    Mating behaviour of the ball-rolling dung beetle Kheper platynotus (Bates), adults of which are active in rainy seasons, was studied in southeastern Kenya. Male mating behaviour changed with the progression of the rainy season. In the early season when females made food balls, males attempted forced copulation with wandering and food-ball-making females on dung mounds. As the season progressed, females made brood balls, and males attempted to pair off with such females, as well as attempting forced copulation with wandering and food-ball-making females. A male who paired off with a brood-ball-making female cooperated with the female to make the ball. The male usually copulate after burying the ball (pre-copulatory mate guarding), but sometimes copulatory during ball-making In the latter case the male usually showed post-copulatory mate guarding until ball burial, but sometimes left soon after copulation. In the late season, when available females decreased because of maternal care in the underground nests, males started to make food balls to secure food resources for survival until the next rainy season. Male mate guarding involving ball-making, -rolling and -burying seemed to function to raise paternity confidence, but such assistance seemed to be less beneficial to females. Fights frequently occurred between guarding and intruding males on brood balls. Both residency and relative body sizes of fighters were important asymmetries influencing contest outcome. This seemed to result in not active but passive mate choice by brood-ball-making females., TAYLOR & FRANCIS LTD, May 1993, JOURNAL OF NATURAL HISTORY, 27 (3), 657 - 668, web_of_science

    1. Spatial, temporal, and dietary differences in resource utilization and patterns of interspecific association on leaves were investigated for dominant and common leaf-mining species on an oak species, Quercus dentata Thunb., in Hokkaido, northern Japan. 2. Leaf miners were divided into two groups according to leaf tissues used for food: upper-layer-feeders which consume the palisade parenchymatous layer (Stigmella spp. and tenthredinid sp.), and full-depth-feeders which consume spongy and palisade parenchymatous layers (Phyllonorycter leucocorona (Kumata), P.similis Kumata, and Caloptilia sapporella (Matsumura)). 3. Differences in the position of mines on leaves were found among species: mines of P.similis were distributed more frequently in the middle section of leaves, whereas those of the remaining species were concentrated in the basal section. 4. Leaf size preference differed between species: C.sapporella and tenthredinid sp. tended to select larger leaves more frequently than did the other species. 5. Phenological differentiation was found among species: C.sapporella appeared earliest, followed by P.similis, P.leucocorona and a tenthredinid sp., and then Stigmella spp. 6. Each species showed a highly clumped distribution among leaves. Leaf miners of some species pairs co-occurred on leaves more frequently than expected by chance., BLACKWELL SCIENCE LTD, Feb. 1991, ECOLOGICAL ENTOMOLOGY, 16 (1), 105 - 113, web_of_science

  • Bionomics of Phyllonorycter (Lepidoptera, Gracillariidae) on Quercus. II. Effects of ants

    Hiroaki Sato; Seigo Higashi

    The effects of ants on a population of Phyllonorycter leaf miners were observed in an oak chaparral on the Ishikari Coast. The density of ant nests was higher at the chaparral's edge than in the interior, while the density of mines was lower at the edge than in the interior. The effects of ant predation were examined in a comparison between treated ant-free trees and untreated ant-rich trees. Percentages of the torn mines observed were higher on the ant-rich trees than on the ant-free trees, whereas the mortality due to parasitoids was higher on the ant-free trees than on the ant-rich trees. This shows that ants greatly contributed to the mortality of leaf miners. © 1987 Ecological Society of Japan., Springer-Verlag, Apr. 1987, Ecological Research, 2 (1), 53 - 60, doi

  • Structure and function of parasitoid assemblages associated with Phyllonorycter leafminers (Lepidoptera : Gracillariidae) on deciduous oaks in Japan

    H Sato; Y Okabayashi; K Kamijo

    Parasitoid assemblages associated with Phyllonorycter spp. leafminers (Lepidoptera: Gracillariidae) were examined on six deciduous oak species (Quercus, Fagaceae) in Japan to understand how host leafminers, host food plants, and geographic location influence the structure and function of parasitoid assemblages. The parasitoid assemblages on five of the six oak species showed similar species richness (18-20 spp.), regardless of the number of host leafminer species and the abundance of hosts. Species composition was influenced by geographic location as well as host food oaks, and to a lesser extent by the leafminers. The assemblages varied in guild structure but showed nearly equal ratios of koinobiont/idiobiont species. The ratio was almost the same as that in Great Britain. These results suggest that the well-known argument that parasitoid communities are mostly influenced by host food plants is not universal, and that parasitoid assemblages may be organized with a balance between numbers of koinobiont and idiobiont species regardless of species richness, species composition, or geographic location. Total rate of parasitism did not correlate with the number of parasitoid species or the evenness of the assemblage. This implies that the host-parasitoid system is not under top-down control., ENTOMOL SOC AMER, Dec. 2002, ENVIRONMENTAL ENTOMOLOGY, 31 (6), 1052 - 1061, web_of_science
