用室养东方实蝇蛹佣小蜂作现场释放试验,观察其对家蝇等蝇种的控制作用。结果,释放点家蝇密度下降了55.9％,厩腐蝇下降了39.9％,丽蝇科种类下降了21.8％,麻蝇科种类下降了17.3％;释放点家蝇蛹的寄生率为29.4％,对照点为11.7％。作者认为,在蝇类孳生场所投放蝇蛹寄生蜂,能够在一定程度上提高蝇蛹寄生率,降低蝇类种群密度。
In the laboratory, the pupal domestica pupae was released for on-the-spot test to observe the control effect on Musca domestica and other fly species. As a result, the density of housefly at the point of release was reduced by 55.9%, the number of stable flies decreased by 39.9%, the species of the family Liriidae decreased by 21.8% and the species of the family Muscidae decreased by 17.3%. The parasitism rate of pupae at the point of release was 29.4% The point is 11.7%. The author believes that the flies breeding places parasitized fly pupae can increase the parasitic rate of fly pupae to a certain extent, reduce the flies population density.
