摘　　要：为进一步揭示转Bt基因抗虫棉对中华草蛉Chrysopa sinica(Tjeder)生物学特性的影响,以泗棉3号和GK-12为材料,以棉蚜为猎物,研究了转基因抗虫棉对中华草蛉存活率、发育历期和繁殖力的影响。结果表明,转基因抗虫棉对中华草蛉幼虫期存活率、幼虫发育历期、蛹发育历期与对照差异均不显著;对成虫寿命、体重以及雌虫繁殖力也无显著差异。表明转Bt抗虫棉对中华草蛉的生物学特性影响较小。The effects of transgenic cotton containing Bacillus thuringiensis （Berliner） CrylAc toxin on the survival rate, developmental duration, and fecundity of a predatory Chinese green lacewing, Chrysopa sinica （Tjeder） , fed cotton aphids, Aphis gossypii （Glover）, were evaluated. There were no significant difference in total survival rates, or in larval and pupal durations of C. sinica supplied with aphids fed on either transgenic or non-transgenic cotton. There were also no significant difference in longevity, fecundity, or weight of adult lacewings. The results indicated that transgenic Bt cotton has little effect on the biological characteristics of C. sinica.
