贪食亚麻蝇Parasarcophaga harpax Pand.是落叶松毛虫Dendrolimus superans Tsai et Liu的重要天敌之一。松毛虫幼虫、蛹被寄生率达67％。在我市林区对控制松毛虫的大发生起到了一定的作用。该蝇分布广、适应性强、寿命长、有利用的价值。为了扩大其种群,增加数量,我站于1979～1981年进行了人工饲养。现将结果介绍如下。虫源贪食亚麻蝇是从我区林内采集被寄生的松毛虫幼虫和蛹,带回室内将钻出寄主的蝇蛆拣出放在装有土壤的铝盒内,让其化蝇和羽化,经鉴定为贪食亚麻蝇后再将其放入笼内。
Parasarcophaga harpax Pand. Is one of the important natural enemies of Dendrolimus superans Tsai et Liu. Dendrolimus larvae and pupae were parasitized at 67%. In the forest in our city to control the occurrence of pine caterpillars played a certain role. The flies widely distributed, adaptable, long life, the value of the use. In order to expand its population and increase its number, I started artificial breeding in 1979-1981. The results are as follows. Insect source bulimia fly is collected from the forest I parasitized pine larvae and pupae, back to the room will be out of the host fly maggot picked out in the aluminum box with soil, let the flies and feathering, Identified as bulimia flies and then into the cage.
