【目的】研究转Bt基因抗虫棉对棉蚜的个体生长发育及繁殖能力的影响。【方法】在室内研究转Bt基因棉(处理)和常规棉(对照)对棉蚜个体生长发育及繁殖能力的影响。【结果】转Bt基因抗棉铃虫棉对棉蚜发育速度、成蚜寿命、4龄若蚜体重、成蚜繁殖力无明显影响。【结论】取食转Bt基因棉花对棉蚜个体生长发育没有负面影响,转Bt基因棉花对棉蚜生长发育和繁殖是安全的。为转Bt基因抗虫棉对棉蚜的生态安全性评价提供相关依据。
【Objective】 The objective of this study was to investigate the effects of transgenic Bt cotton on individual growth and reproduction of cotton aphids. 【Method】 The effects of transgenic Bt cotton (treated) and conventional cotton (control) on the individual growth and reproduction of cotton aphid were studied indoors. 【Result】 The transgenic Bt cotton bollworm had no significant effect on the development of cotton aphid, the longevity of aphids, the body weight of 4th instar aphids and the fertility of aphids. 【Conclusion】 There is no negative effect on growth and development of individual cotton aphids by feeding transgenic Bt cotton. Transgenic Bt cotton is safe for the growth and reproduction of cotton aphid. It provides the basis for evaluating the ecological security of Bt cotton on cotton aphid.
