摘要
本文对广东菜区美洲斑潜蝇Liriomyza sativae寄生性天敌的种类及寄生情况进行了初步调查。结果表明,常见的美洲斑潜蝇寄生蜂有5 种,其中以底比斯釉姬小蜂Chrysocharisrentheus和冈崎釉姬小蜂Chrysonotomyia okagakii为优势种。在不受化学农药的干扰下,作物生长后期美洲斑潜蝇被寄生率可高达47.2- 68.4,寄生性天敌对其自然种群起着重要的控制作用。
The parasitoids of the vegetable leafminer, \%Liriomyza sativae \% Blanchard were surveyed and studied in vegetable area of Guangdong Province, China. A total of 5 species parasitoids were collected from the larvae and pupae of the leafminer. Amony these, \%Chrysocharis pentheus \%and \%Chrysonotomyia okagakii\% were the commonest species. The parasitism of leafminer in the untreated plot ranges from 47 16% to 68 42% at the later growing stage of host plant. It was concluded that the parasitoids played an important role in the natural control of this pest.
