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。 In order to reveal the effect of transgenic Bt cotton on the biological characteristics of Chrysopa sinica (Tjeder), the cotton aphid was used as the prey to study the effects of transgenic insect-resistant cotton The effects of survival rate, developmental duration and fecundity of the shrews. The results showed that there was no significant difference in the survival rate of larvae, the larval developmental stages, the developmental duration of pupal and the control between the transgenic Bt cotton and larvae. There was also no significant difference in the longevity, body weight and fecundity of adult larvae. The results showed that transgenic Bt cotton had little effect on the biological characteristics of Chinese weed.
