黄粉甲蛹低温贮存时间对管氏硬皮肿腿蜂母代和子代寄生与繁育的影响

Influence of Storage Time of Tenebrio molitor(Coleoptera:Tenebrionidae)pupa at Low Temperature on Parasitoid or Reproduction of Maternal and Offspring of Scleroderma guani(Hymenoptera:Bethylidae)

研究繁蜂替代寄主黄粉甲蛹经-9℃贮存5、15、25、35和45d后所繁育出的管氏硬皮肿腿蜂对青杨天牛寄生的影响。母代蜂在产卵前期、幼虫期、寄生率、幼虫存活率以及产卵量、出蜂量间与对照存在显著差异。但子代蜂各阶段发育历期、存活率、产卵量、出蜂量等各方面与对照则均无显著差异。

Maternal effects of Scleroderma guani bred on Tenebrio molitor, an ectoparasitoid of Saperda populnea （ Coleoptera ： Cerambycidae） had been studied. There was significant difference in pre-oviposition period, larval preiod, parasite rate, larval survival rate, the number of oviposition and the number of adult of maternal wasps between the S, guani reared on the T. molitor stored respectively at - 9 ℃ for 5,15,25,35 and 45 d and untrated control. However, the affspring derived from the treated S. guani didn＇t show any significance from the untreated control.
