Abstract: 通过室内饲养实验及水稻氨基酸和碳、氮含量测定,比较研究了转cry1Ab水稻克螟稻(KMD1和KMD2)与其亲本秀水11对非靶标害虫白背飞虱种群增长的影响.结果表明,以克螟稻为食可对白背飞虱的产卵期和每雌产卵量产生一定影响.以KMD2为食的白背飞虱的产卵期为7.6天,每雌产卵量为95.0粒,均显著低于以母本秀水11为食的白背飞虱的12.7天和167.5粒.但是,以KMD1为食的白背飞虱仅产卵期(8.6天)显著变短,其每雌产卵量与以其母本秀水11为食的白背飞虱无显著差异.稻苗氨基酸含量分析结果表明,KMD2引起白背飞虱种群生殖力显著下降可能与其游离氨基酸的总量和丙氨酸含量的显著下降以及谷氨酸含量的显著上升有关.因此,转cry1Ab水稻可对白背飞虱种群增长产生影响,但其影响因转cry1Ab水稻品种而异.
