通过4年的调查研究,在辽宁省沈阳和吉林省延吉两地发现天幕毛虫(Malacosoma neustria testaceaMotschulsky)卵的寄生蜂共6种:天幕毛虫黑卵蜂〔Telenomus terbraus(Ratzeburg)〕、毒蛾黑卵蜂(暂拟)(Telcnomus sp.)、大蛾卵跳小蜂〔Gocncyrtus Kuwanae(Howard)〕、斑角跳小蜂〔O.masii(Merc.)〕、舞毒蛾卵平腹小蜂〔Anastatus disparis(Rusch.)〕、松毛虫赤眼蜂(Trichogramma dendrolimi Matsumura)。其中在天幕毛虫卵内越冬者有4种,寄生率为13.6%—18.0%,以天幕毛虫黑卵蜂及大蛾卵跳小蜂为优势种;当年世代有4种,寄生率为7.1%—11.3%,以大蛾卵跳小蜂及舞毒蛾卵平腹小蜂为优势种
Through 4 years of investigation, there are 6 parasitic wasps found in the eggs of Malacosoma neustria testacea Motschulsky in Shenyang of Liaoning Province and Yanji of Jilin Province: Telenomus terbraus (Ratzeburg) (Telcnomus sp.), Gocncyrtus Kuwanae (Howard), O.masii (Merc.), Anastatus disparis Rusch.)], Trichogramma dendrolimi Matsumura. Among them, there were 4 wintering individuals in the Anemone cristata eggs, with the parasitism rate being 13.6% -18.0%, with the dominant species being the black-eyed bee and the big-moulted egg-jumping wasp; in the current generation, there were 4 species with a parasitic rate of 7.1% -11.3%, with the big moth oviposition wasp and the gypsy moth eggs flat belly wasps as the dominant species
