摘要
通过野外调查和室内饲养,发现茶翅蝽卵期、成虫期天敌共有9种,6种为寄生性,3种为捕食性。其中卵期天敌有7种,寄生蜂有6种:茶翅蝽沟卵蜂(Trissolcus halyomorphae)(新种,膜翅目(Hymenoptera)黑卵蜂科(Scelionidae))、沟卵蜂(Trissolcus sp.)、角槽黑卵蜂(Telenomus sp.)、蝽卵金小蜂(Acroclisoides sp.)、平腹小蜂(Anastatus sp.)、蝽卵跳小蜂(Ooencyrtus sp.),捕食性天敌1种:小花蝽(Orius sp.)(半翅目(Hemiptera)花蝽科(Anthocoridae)。若虫、成虫期天敌2种:蝎蝽(Arma chinensis)(半翅目蝽科)、三突花蛛(Misumena tricuspidata(Fabricius)(蜘蛛目(Araneida)蟹蛛科(Thomisidae))。优势天敌是茶翅蝽沟卵蜂,茶翅蝽卵中的自然寄生率为20%~70%,平均为50%。
The natural enemies attacked the bug in its each stage had been investigated. A total of 9 species of natural enemies were found, including 6 parasitoids: Trissolcus halyomorphae (Hymenoptera) ; Scelionidae, Trissolcus sp. , Telenomus sp. , Acroclisoides sp. , Anastatus sp. , Ooencyrtus sp. , Orius sp. (Hemiptera.Anthocoridae), Arma chinensis(Hemiptera.) Pentatomidae and Misurnena tricuspidata (Araneida.Thomisidae). The predominant natural enemy of the pest was T. halyomorphae. Its parasitism rate could reach 20%-70%, on an average 50%.
