2种瓜实蝇寄生蜂的研究进展

Research Progress in Two Parasitoids of Bactrocera Cucurbitae(Coquillett)

瓜实蝇(Bactrocera cucurbitae Coquillett)是危害多种蔬菜和水果的重要害虫,化学防治效果成效甚微,生物防治有望成为最有潜力的防治技术。本文主要对瓜实蝇的寄生性天敌阿里山潜蝇茧蜂(Fopius arisanus Sonan)和弗氏短背茧蜂(Psyttalia fletcheri Silvestri)的生物学特性、影响寄生蜂存活和雌雄性比的主要因素、寄主范围及寄主选择性、扩繁技术及其对实蝇的防治效果等方面进行综述,为2种蜂在瓜实蝇生物防治中的应用提供参考。

Bactrocera cucurbitae（Coquillett） is an important insect pest against fruit and vegetable. The effect of chemical control to B. cucurbitae is low. Therefore, biological control becomes the most potential method against B. cucurbitae gradually. In this paper, biological characteristics, the effect of survival and sex ratio, host range and selection, propagation technique, control effectof two parasitoids of B. cucurbitae, Fopius arisanus and Psyttalia fletcheri,were reviewed, which could provide a reference to the application of two parasitoids.
