近几年来,利用颗粒体病毒防治菜粉蝶(Pieris rapae以下称菜青虫)幼虫的工作,在我国已取得了较好的进展(梁东瑞等,1979;河北省菜青虫颗粒体病毒研究协作组,1981)。病毒杀虫剂与化学杀虫剂的显著区别之一,是前者具有选择性,不直接杀伤天敌昆虫。为了明确颗粒体病毒防治菜青虫对寄生蜂种群的影响,以便进一步了解病毒治虫在保持生态平衡上的意义,我们对颗粒体病毒、微红绒茧蜂(Apanteles rubecula)、菜青虫的相互关系作了一些实验室研究,现报道初步结果如后。
In recent years, the use of granulosis virus control Pieris rapae (Pieris rapae hereinafter referred to Pieris rapae) larvae work has made good progress in China (Liang Dongrui et al., 1979; Hebei cabbage caterpillar virus research collaboration group, 1981 ). One of the significant differences between viral insecticides and chemical pesticides is that the former is selective and does not directly kill natural enemies. In order to clarify the effect of granulosis virus on the parasitoid population in order to know more about the significance of viral pest control in ecological balance, the relationship between granulovirus, Apanteles rubecula and cabbage worm A number of laboratory studies are now reported as initial results.
