试验证阴暗黑赤眼蜂孤雌生殖能产雌雄两性子代。雌蜂占90％以上,与两性生殖没有区别。在山西运城该蜂寄生棉铃虫及黄地老虎卵,人工接种时也能寄生杨雪毒蛾和多种夜蛾科害虫卵,但不能在柞蚕、蓖麻蚕卵内寄生。用杨雪毒蛾卵作寄主繁殖该蜂,方法简便,效果良好。在棉田小区中分别释放暗黑赤眼蜂和松毛虫赤眼蜂防治棉铃虫,寄生率分别为63.7％和47.9％。由于该蜂雌性比特高,对棉铃虫的防治效果较好,值得进一步研究。
Test certificate Dark Dark Trichogramma parthenogenesis can produce both male and female offspring. Female bees accounted for more than 90%, and no difference between genital reproduction. The bee parasitic Helicoverpa armigera and yellow tiger eggs in Yuncheng, Shanxi Province can also parasitize the eggs of Populus euphorbiae and various noctuid insects during artificial inoculation, but can not parasitize eggs in tussah and castor silkworm eggs. The use of Yang Xue Tong moth eggs for the breeding of the bee, the method is simple, the effect is good. In the plot of cotton field, Trichogramma dendrolimi and Trichogramma dendrolimi were respectively released to control the cotton bollworm with parasitic rates of 63.7% and 47.9% respectively. Due to the high female bites, the control effect on the cotton bollworm is good and worthy of further study.
