摘　　要：在西藏境内进行昆虫天敌资源调查时,采集到大量的农林重大害虫皱大球蚧、樱桃球蚧、绛蚧,并饲养出2种花角跳小蜂(膜翅目:跳小蜂科),即不列颠花角跳小蜂Blastothrix brittanica Girault, 1917(寄生皱大球蚧、樱桃球蚧)和中国花角跳小蜂Blastothrix chinensis Shi, 1990(寄生绛蚧),经文献及数据库查询确定为西藏新记录种,这2种花角跳小蜂均为重要的膜翅类天敌寄生蜂。对新记录种的形态特征、分布和寄主进行了详细的记述,并给出了花角跳小蜂属中国种类的分种检索表。该研究将有助于西藏地区生物防治工作的开展。During the investigation of insect natural enemy resources in Xizang,a large number of major agricultural and forestry pests were collected including Eulecanium kuwanai Kanda,E.cerasorum(Cockerell)and Kermes sp..Two species of Blastothrix(Hymenoptera:Encyrtidae),namely Blastothrix brittanica Girault and Blastothrix chinensis Shi were identified as newly recorded species in Tibet through literature and database search.These two species were important hymenopteran natural enemies.The morphological characteristics,distribution and hosts of the newly recorded species were described in detail,and the taxonomic search table of Chinese species of the genus Encyrtidae was given.This study will contribute to the development of biological control in Xizang.
