摘　　要：经对辽宁省岫岩蔬菜区美洲斑潜蝇和南美斑潜蝇的寄生蜂及其寄生情况的初步调查,结果表明,这两种斑潜蝇的寄生蜂有9种。其中优势种群有潜蝇姬小蜂和茧蜂科的种类3种以上。在蔬菜田不用杀虫剂的情况下,寄生蜂6月中旬后迅速上升,7月份对两种斑潜蝇的寄生率可达75%以上,对斑潜蝇种群具有明显的控制作用,可使夏、秋季田间两种斑潜蝇种群迅速下降,一般不需防治。Preliminary surveillance on parasitoid controlling Liriomyza sativae and Liriomyza huidobrensis was done in vegetable fields in Xiuyan county, Liaoning province. Results showed that there were 9 species of parasitoids, in which at least 3 species were Diglyphus isaea and Braconidae. The total numbers of parasitoids increased quickly after mid-June, parasitical rate reached 75% in July, which led to the substantive decrease of the populations of Liriomyza sativae and Liriomyza huidobrensis in summer and autumn in fields, so there was no need to control the two pests in general situation.
