Study on the evolution and adaptation of higher Diptera in Japan

1. 从寄主偏好与形态结构的关系出发，研究了双翅目速蝇科昆虫的寄生策略及其进化。结果表明，在寄主偏好策略的选择上，某些速虫应被置于不同于速虫科有序分类的系统位置。第3届亚洲/太平洋昆虫学会议（1997年8月，台湾台中）。研究了沙蚕属及其近缘虫的卵、幼虫、寄主偏好、雌性生殖器官和产卵习性。发现了一种老年视卵的微型卵没有硬绒毛膜。这种卵在塔奇亚科中从未被发现过，考虑到其系统地位和卡西利亚及其盟友的进化关系，其产卵习性需要大量的证实。部分研究成果已在1998年9月于英国牛津举行的第四届国际昆虫学大会上发表。根据已发表的记录和作者积累的资料，编制了日本速蝇科寄主-寄生虫目录。结果表明，180余只日本速蛾分别寄生鳞翅目330种、鞘翅目23种、半翅目和膜翅目30种、直翅目9种、螳螂目2种、皮翅目和Phasmida目1种。本文采用了速蝇科和寄主种的当代学名，并列举了速蝇种的许多近义词。

1. Parasitic strategy and evolution of the Tachinidae (Diptera) were studied in considering the relationship between host preference and morphological structures of flies. It became clear that some tachinids should be placed in different systematic position from the ordinal classification of the Tachinidae in adopting their host preference strategy. A part of this was presented at the 3rd Asia/Pacific Conference of Entomology (August, 1997, Taichung, Taiwan).2. The genus Carcelia and its allies were studied in their eggs, larvae, host preference, female reproductive organ and female ovipositing habits. It was discovered that a species of Senometopia had microtype eggs without hard chorion. This kind of eggs has been never known in the Tachinidae, and its ovipositing habits need much confirmation for considering its systematic position and evolutional relationships of Carcelia and its allies. A part of the results was presented at the 4th International Congress of Dipterology (September, 1998, Oxford, England).3. A host-parasite catalog of Japanese Tachinidae was compiled with published records and data accumulated by the author. It becomes clear that some 180 Japanese tachinids parasitize about 330 species of Lepidoptera, 23 of Coleoptera, 30 of Hemiptera and Hymenoptera, 9 of Orthoptera, 2 of Manthodea and 1 of Dermaptera and Phasmida. Contemporary scientific names of both Tachinidae and host species were adopted and many synonyms of tachinid species are listed.
