中文摘要：在棉铃虫HelicoverpaarmigeraHübner人工饲料中分别添加转Bt基因棉叶粉和常规棉叶粉饲喂幼虫,经滞育诱导后,发现2个处理间棉铃虫蛹的滞育率相似,2个处理间滞育蛹的自由水和结合水含量没有差异;但取食含Bt棉叶粉人工饲料的棉铃虫滞育蛹的过冷却点和结冰点显著高于对照组
英文摘要：Helicoverpa armigera Hübner feeding on artificial diets with transgenic Bt cotton leaves or non-transgenic cotton leaves were induced to diapause, and then the cold hardiness of the pupae in diapause was studied. The results showed that there was
