项目摘要

Nestmate discrimination is one of the key function of the colony life in social insects.1)Learning ability of workers to discriminate their queen in the newly-emerged carpenter ant, Camponotus japonicus, depends on the individuals. Discriminative ability was found to coincide with the completion of cell proliferation in the brain. In relation to this brain maturation, postembryonic development of the mushroom bodies was analyzed in detail.2)For Camponotus japonicus, cuticular hydrocarbon (CHC) blends produced by non-nestmates elicit strong aggression. The specific sensillum on the antennae was identified to respond only to non-nestmates CHC blends, This sensillum seemed to play a key role for a peripheral recognition mechanism in detecting colony-specific chemical signals.3)In honeybees, recognition cues seem to be much wider. To investigate the process of template renewal probably in the brain, workers showing the nestmate discrimination ability were exposed to unfamiliar colony environments by keeping with non-nestmates for a while. They changed their template rapidly by referring to the inner-colony environment but retain the old template temporally in the early phase of the template renewal. Role of environment-originated odors temporally adsorbed onto the cuticular wax and the fatty acids were also analyzed in detail.4)Social parasitism seen in the hornets, Vespa dybowskii and V.simillima, was investigated from the point of view of nestmate recognition.

巢师歧视是社会昆虫中殖民地生活的关键功能之一。1）工人在新出现的木匠蚂蚁（Camponotus japonicus）中歧视女王的学习能力取决于个人。发现判别能力与大脑中细胞增殖的完成相吻合。关于这种大脑的成熟，详细分析了蘑菇体的胚胎后发育。鉴定出触角上的特定感觉仅对非巢穴CHC混合物做出反应，这种感觉似乎在检测蜜蜂中检测殖民地特异性化学信号中的外围识别机制起着关键作用。在蜜蜂中，识别提示似乎更宽。为了研究大脑中更新模板更新的过程，表现出表现出巢穴歧视能力的工人通过与非仇恨者保持一段时间来暴露于陌生的菌落环境中。他们通过指代内层环境来迅速更改模板，但在模板更新的早期阶段将旧模板保留。从黄蜂，Vespa Dybowskii和V.Simillima中看到的社会寄生虫，还分析了在时间上吸附到表皮蜡上的环境寄生的作用，并从巢穴识别的角度研究了社会寄生虫。
