摘要
以大蜡螟的低龄幼虫为寄主,在实验室条件下对蜡螟绒茧蜂的寄生作用进行了研究。结果表明:蜡螟绒茧蜂一生最多产卵68粒,平均45.85粒。蜡螟绒茧蜂卵产于寄主体内的位置多在1～4腹节;多数在寄主体内只产1粒或2粒卵。该蜂能寄生大蜡螟1～4龄幼虫,但2～4龄幼虫同时存在时,偏爱寄生2、3龄幼虫,其选择系数分别为0.35和0.42。
The parasitism of Apanteles galleriae was studied in the laboratory condition with the young larvae of Galleria mellonela as its host.The results showed that the female wasp laid 45.85 eggs on the average,with the most being 68 eggs.The eggs were mostly oviposited in the 1 st to 4th abdomen of the host,and only one or two eggs were laid in most hosts.A.galleriae could parasitize 1-4th instars of G.mellonella,and preferred the 2nd and 3rd instar.The preference indexes were 0.35 and 0.42,respectively, for 2nd and 3rd instars when the wasp was exposed to the 2nd,3rd and 4th instars of host simultaneously.
