摘要
1987~1992年连续6年研究结果表明,白跗平腹小蜂Anastatusalbitarsis对马尾松毛虫Dendrolimuspunctatus、柳杉毛虫Dendrolimuslatipennis、水青蛾Actiasseteneningpoana等13种主要森林害虫卵有较明显的抑制作用。在林间,该蜂对马尾松毛虫第1、2代卵的自然抑制力分别力16.55%和22.29%,对柳杉毛虫越冬代卵的自然抑制力为23.45%;对水青蛾第1、2代卵的抑制力分别力5.49%和2.63%;在林间,人为释放白跗平腹小蜂对第1代马尾松毛虫卵的校正抑制力为33.5%,在室内12.3~28℃范围内,每头雌峰对马尾松毛虫、水青蛾和柞蚕剖腹卵的日破坏数(寄生数)分别力15、18和26粒,一生破坏数分别为56、91和208粒。即使虫卵即将孵化,该峰同样亦能寄生,并羽化出正常的子代白跗平腹小蜂。
years studies from 1987 to 1992 resulted that Anastatus albitarsis had evident inhibition effect on eggs of 13 species of main forest insects like Dendrolimus punctatus, D. latfpennis, Actial setene ningpoana. In forest, natural inhibition effect on the first and second generation of D. punctatus egg were respectively 16.55% and 22 .29%, on overwintered egg of D.latipennis was 23.45%, on the first and second generation of A.setene ningpoana egg were 5 .49% and 2.63%,corrected inhibition effect of artificial released A. albitarsis on the first generation of D. punctatus egg was 33.5%. In laboratory, D. punctatus, A. setene ningpoana and Antheraea pernyi egg parasited by each female A. albitarsis were 15,18 and 26/day, 56,91 and 208/life.
