摘要
作者从浙江东南沿海台州地区室内常见蜚蠊卵荚中发现了拟噬小蜂Tetrastichodes sp.和蜚卵旗蜂Evania appendigaster两种蜚蠊天敌。拟噬小蜂在寄生蜂中占90.38%,能寄生于各种室内常见蜚蠊卵荚,自然寄生率为11.87%,每只卵荚内自然寄生数达70.6只,有望用于防制当地室内常见蜚蠊。卵荚寄生蜂的自然寄生率与蜂种、寄主蠊种和卵荚内自然寄生数等有关。
Tetrastichodes sp and Evania appendigaster are found to be the natural enemy of Blatta ootheca which is common indoors in Taizhou Prefecture, Southeast coastal area of Zhejiang Prouince. Tetrastichodes sp makes up 90.38% of the parasitic wasp, It can parasitize in every common Blatta ootheca. Their natural parasite rate is 11.87%. The natural parasite count reaches 70.6 in enery ootheca. Therefore, it is expected to prevent and treat the Local Blatta. The natural parasite rate of oothecal parasitic wasp is related with the wasp type. Blatta host and the natural parasite count in ootheca.
