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 investigation of the parasitic wasps and their parasitism on the leafy ground louse and the ground-lined Liriomyza sativae in the Xiuyan vegetable area in Liaoning Province showed that there were 9 parasitoids of these two species of Liriomyza sativa. Among the dominant species, there are three or more species of the latent mosquito Hymenoptera and Braconidae. In the case of no pesticides in vegetable fields, the parasitic wasps rapidly increased after mid-June, and the parasitism rate to the two species of leafminers in July was over 75%, which obviously controlled the population of the leafminers In summer and autumn, the population of two species of Liriomyza sativae decreased rapidly, generally without control.
