根据国内外文献记载,粘虫白星姬蜂Vulgichneumon leucaniae Uchida寄主为粘虫LeucaniaSeparata Walker,偶有寄生大螟Sesamia inferens(Walker)。我们在研究我省重要蔬菜害虫——甘蓝夜蛾的过程中,发现粘虫白星姬蜂也寄生于甘蓝夜蛾的蛹期,其寄生率为16.7％。虽寄生率较低。但对于控制甘蓝夜蛾的大量发生提供一个可以考虑的途径。 According to the literature at home and abroad, the host of the armyworm, Vulgichneumon leucaniae Uchida, is the armyworm LeucaniaSeparata Walker, with occasional parasitic stem borer Sesamia inferens (Walker). During the study of the important vegetable pest in our province, the cabbage budworm, we found that the whiteworm Mythimna separatae also parasitized at the pupal stage of the cabbage budworm, with a parasitic rate of 16.7%. Although the parasitic rate is low. But it provides a possible way to control the occurrence of cabbage moth.
