| Abstract |
有剣ハチ類は送粉や食物網の制御など，生態系において重要な役割を果たしている。しかし，北海道道東地域における有剣ハチ類相は明らかになっておらず，過去の出現情報をもとにした時間的群集変動を評価できない状況にある。本調査では，標高を広くカバーしている九州大学農学部附属北海道演習林および足寄町国有林において，有剣ハチ類の種とその出現情報を記録した。異なる季節にイエローパントラップを用いて有剣ハチ類を採集し...たところ，246個体62種が採集され，その内５種が北海道初記録種であった。パントラップで採集される主な種については記録できたと考えられるが，有剣ハチ類相全体の解明には，パントラップ以外の複数の採集方法を組み合わせ，林縁部や草地などの異なる環境で調査を行う必要がある。
Aculeata bees and wasps play important roles in ecosystems such as pollination and food web control. However, it is not possible to evaluate temporal community changes based on past occurrence data, because distribution records of aculeate wasps and bees in the East Hokkaido region have been poor. In this study, we recorded the species and their occurrence data in the Ashoro Research Forest, Kyushu Univ. and Biribetsu National Forest, Hokkaido, which cover a wide elevational range. We collected Aculeata using yellow pan traps in different seasons and identified a total of 246 individuals belonging to 62 species, five of which were recorded from Hokkaido for the first time. Although the main species collected by yellow pan traps were recorded, to elucidate the entire Aculeata fauna, it is necessary to conduct surveys in different environments, such as forest edges and grasslands, and using collection methods other than pan traps.show more
