Abstract

尾瀬国立公園内におけるアザミウマ相調査の結果,3科26属59種のアザミウマ類が記録された.山岳域特異性種と考えられる4種は,尾瀬国立公園内でも山岳域以外からは確認されなかった.Taeniothrips sp.1とThrips sp.2は,尾瀬ヶ原からしか確認されず,また,尾瀬国立公園以外でも生息が確認されていない.寄主植物も合わせて考えると,これら2種は生息環境として尾瀬ヶ原のような広大な湿原環境を必要としているのかもしれない.尾瀬国立公園内に広く分布するStenchaetothrips dentatus Masumoto and Okajima, 2013は,これまでにオスの特徴が報告されていないため,主要な形態的特徴を記載した.
Through the thrips faunal surveys in the Oze national park in Japan, we have recorded 59 species belonging to 26 genera of three families from the Oze mountainous area, Ozegahara area, and Ozenuma and area surrounding it. Four species that are considered to inhabit only mountain areas, Apterothrips secticornis (Trybom, 1896), Thrips pini (Uzel, 1895), Thrips sp.1, and Bactrothrips montanus Haga and Okajima, 1989, were not recorded in the Ozegahara area, nor were they recorded in Ozenuma and area surrounding it. Five other species, Anaphothrips badius (Williams, 1913), Taeniothrips sp.1, Thrips sp.2, Haplothrips sp.1, and Liothrips sp.1, appear to require a marsh environment as a habitat considering their distribution and host plants in the Oze national park. Among them, Taeniothrips sp.1 and Thrips sp.2, which utilize mugwort (Artemisia) and Inula ciliaris (Miq.) Maxim. var. glandulosa Kitam. (Asteraceae) as a host plant, respectively, are unrecorded species in Japan that are distributed only in the Ozegahara area. These two species may require a vast marsh environment, such as the Ozegahara moor as a habitat. Stenchaetothrips dentatus Masumoto and Okajima, 2013, which utilizes bamboo grass as a host plant, is widely distributed in the Oze national park. As no characteristics of the males of this species have been reported so far, only the main morphological characteristics were described.
