摘要
作者自1980～1987年期间对山西代表地区蝇类的寄生性天敌进行了详细的调查,共发现21种膜翅目寄生蜂和3种鞘翅目昆虫。调查结果表明:在自然界蝇蛹被寄生性天敌所寄生的平均寄生率为12.0%,同时筛选出两种寄生性优势蜂种,并对其在自然界的寄生率、性比及季节消长进行了研究。
The parasitic natural enemy of fly pupae in Shanxi province was inve- stigated during the past years.Twenty-Four species of the natural enemy were discovered of which 21 species were subordinate to the Hymenoptera and 3 species were subordinate to the Coleoptera.Two species of the para- sitic natural enemy,Spalangia endius and Nasonia vitripennis,were disco- vered as the dominative species in Shanxi province.The natural parasitiza- tion,sex rate and seasonal occurrence of the two dominative species were studied.
