摘要: 以常规棉泗棉3号上饲养10代的棉蚜作为虫源,以其亲本为对照,在室内分别研究了转单、双价基因抗虫棉对棉蚜的短期影响,及单价抗虫棉对棉蚜的长期效应。结果发现,单价抗虫棉GK12和双价抗虫棉SGK321在短期内对棉蚜生长发育、繁殖和生命表参数无显著影响。在抗虫棉上取食1代的棉蚜,各龄发育历期、成虫寿命、产仔数和产仔历期、内禀增长率、净增长率、平均发育历期等和取食亲本的棉蚜之间均无显著差异。在GK12上取食37代的棉蚜与取食亲本常规棉泗棉3号和在GK12上取食1代的棉蚜之间以上各指标也无显著差异。可见,单价抗虫棉GK12和双价抗虫棉SGK321在短期内对棉蚜的生长发育和繁殖均无显著影响,GK12在长期内对棉蚜也未产生显著影响。

Abstract: The short-run impacts of transgenic insectresistant cotton cvs.GK12 and SGK321 and long-term impacts of GK12 on cotton aphids Aphis gossypii Glover were evaluated by laboratory experiments.Laboratory cotton aphid population kept on non-transgenic cotton cv.Simian 3 for ten generations was used for the experiments,and the isogenic non-transformed varieties of GK12 and SGK321 were used as their relative controls.The results indicated that GK12 and SGK321 had no impacts on the development,reproduction and parameters of life tables of cotton aphids in the short run.When fed on transgenic cotton cv GK12 or SGK321 for one generation,the development period of each instars larvae,adult longevity,number of offsprings,reproduction period,intrinsic rate of increase,net reproductive rate,average development period of cotton aphids did not differ significantly to those of cotton aphids fed on their relative isogenic cotton.GK12 showed no impacts on the development and fecundity of cotton aphids,even the cotton aphids were fed with GK12 for 37 generations.So it was concluded that there were no impacts of transgenic insect-resistant cotton GK12 and SGK321 on the development and reproduction of cotton aphid both in the short run,and GK12 had no impacts on cotton aphid in the long term.
