为了探究转 Bt基因水稻对东亚飞蝗抗寒性的影响，在室内条件下以转 Bt基因水稻和非转基因水稻分别喂养东亚飞蝗3代，用过冷却点仪测定东亚飞蝗的过冷却点和冰点。结果表明，转 Bt基因水稻饲养的东亚飞蝗的4龄、5龄幼虫、成虫(雌和雄)的过冷却点分别为-5.89、-7.59、-6.64和-6.79，与对照组无显著差异。

In this study, the Bt-transgenic and non-transgenic rice were fed to three generations of oriental migratory Iocust, respectiveIy under Iaboratory conditions so as to investigate the effects of Bt-transgenic rice on coId resistance of oriental migratory Iocust. The supercooIing point and freezing point of oriental migratory Iocust was de-termined using supercooIing point meter. The resuIts showed that the supercooIing points of fourth instar Iarvae, fifth instar Iarvae, male aduIts and female aduIts, which were al fed with Bt-transgenic rice, were -5.89, -7.59, -6.64 and -6.79, respectiveIy.
