在午毒蛾的寄生物中有些特别引人注意的寄生在卵期能将其消灭在开始为害以前的种类。可以有把握的说,其中最有实践意义的是平腹小蜂Anastatus disp-aris。它广泛分布于俄罗斯的草原地带,乌克兰、克里木、乌兹别克斯坦、吉尔吉斯、巴萨基尼亚和远东(大陆部分),在很多欧洲国家、日本和美国也有发现。在最适宜的条件下平腹小蜂能感染60—100％的午毒蛾卵块;而在个别的卵块的卵粒寄生率达68.5％。
Some particularly noteworthy parasites in the gnat moth can eradicate the species before the onset of damage in the egg stage. It is safe to say that Anastatus disp-aris is one of the most practical examples. It is widely distributed in Russia’s grasslands. Ukraine, Crimea, Uzbekistan, Kyrgyzstan, Bazhenya and the Far East (the mainland) have also been discovered in many European countries, Japan and the United States. In the most suitable conditions, Baphicola equans can infect 60-100% of the eggs of Ligustrum lucidum while the parasitism rate of eggs in individual eggs is 68.5%.
