| 摘 要： | 以我国研制的转基因棉(Bt）品系MD-80为材料，系统研究了对棉铃虫的控制作用。结果表明，转基因棉对棉铃虫初孵幼虫具有较强的杀虫活性，棉铃虫5龄幼虫连续取食转基因棉叶片和棉蕾化蛹率与羽化率下降，棉铃虫成虫取食转基因棉花蜜产卵量和卵孵化率降低，棉铃虫3龄幼虫在转基因棉株上的活动发生明显变化。

Evaluation of Transgenetic Bt-cotton in Xinjiang Cotton Area |
| |
| Abstract: | The effect of Bt cotton cultivar MD 80 was evaluated in laboratory and field against cotton bollworm .The larvae poccessed a high mortality when they fed on Bt cotton leaves . The percentage of pupating and moth emerging lowered when the 5th instar larvae were fed continually with Bt cotton leaves . Oviposition and egg hatching rate lowered when adults fed on Bt cotton flowers.The behavior of 3rd instar larvae changed obviously when they fed on Bt cotton in the field. |
