转Bt cry1F基因抗虫玉米对米蛾生长发育的影响

Effect of Transgenic Insect-resistant Corn with cry1F Gene on Growth and Development of Rice Moth,Corcyra cephalonica(Stainton)

采用转Bt cry1F基因的32A91、32W09和X1132X 3个玉米品种及其对应的3种非转基因玉米为试材,分别饲养米蛾幼虫,比较转基因和非转基因玉米对米蛾生长发育的影响。结果表明,转cry1F基因玉米对米蛾幼虫存活率的影响均表现为显著降低;转基因玉米32W09饲养的米蛾成虫羽化率显著低于非转基因玉米XY420饲养的米蛾成虫羽化率。

In this article,three varieties of transgenic insect-resistant corn with cry1F gene,32A91,32W09 and X1132X,and non-transgenic corn were used as test materials to feed Corcyra cephalonica larvae.In contrast to non-transgenic corn,the survial rate of larvae in transgenic corn showed a signficant decrease.For the emergence rate of adult Corcyra cephalonica,32W09 group demostrated an obvious decline in comparison with non-transgenic corn XY420.However,the other two groups had no significant differences.
