밤나무혹벌의 천적종류와 발생소장을 조사하였다. 국내 천적종류는 Torymus sinensis, Torymus geranii(남색 긴꼬리좀벌), Eurytoma brunniventris(상수리좀벌), Eurytoma setigera, Megastigmus maculipennis(배잘룩꼬리좀벌), Megastigmus nipponicus(노란꼬리좀벌), Ormyrus flavitibialis(노란다리남색좀벌), Ormyrus punctiger(큰다리 남색좀벌), Eupelmus urozonus(노란꼬리벼룩좀벌), Eupelmus sp., Sycophila variegata, Diptera sp.(파리 1종)로 동정 되었다. 이들 천적 가운데 Torymus sinensis, Eurytoma setigera, Eupelmus sp.는 국내에 분포하는 것이 최초로 확인되었다. 천적의 계절별 발생소장을 경기지방에서 조사한 결과, Torymus sinensis의 성충은 전년의 형성된 벌레혹으로부터 이듬해 4월~5월에 우화하였으며 각조사지역에서 최우점종이었다. Torymus geranii, Sycophila variegata, Eupelmus urozonus(노란꼬리벼룩좀벌), Eupelmus sp.의 성충은 전년 및 당년에 형성된 벌레혹 모두에서 각각 4~5월과 6~8월에 우화하였으며, 이외의 기생벌 성충은 당년에 형성된 벌레혹으로부터 6~8월에 우화하였다.

This study was conducted to mvestigate the natural enemies of chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu and their seasonal prevalence of adult emergence. The natural enemies Identified were as follows: Torymus sinensis, Torymus geranii, Eutytoma Brunniventris, Eurytoma s Setlgera, Megastigmus nipponicus, Megastigmus maculipennis, Ormyrus flavrtrbwlis, Ormyrus punctiger, Eupelmus urozonus, Euplmus sp., Sycophila vanegata, and Diptem sp. Among these natural enemies of the chestnut gall wasp, Torymus sinensis, Eurytoma setigem, and Eupelmus sp. were newly recorded this time In Korea. The seasonal prevalence of parasItic wasps have been investigated in Kyonggi ProvInce. Torymus sinensis which seems to be the most dominant parasitoid emerged from withered galls formed in the previous year April to eary May. The four parasitoids such as Torymus geranii, Sycophila variegata, Eupelmus urozonus and Eupelmus sp. emerged from withered previous year galls in April to May and also from current year galls in June to August. The other parasitoids emerged from only current year galls in June to August.
