摘　　要：【目的】评价转cry1Ab/Ac基因抗虫水稻(华恢1号,HH1)对非靶标害虫褐飞虱Nilaparvata lugens(St?l)及其2种天敌(蜘蛛和黑肩绿盲蝽Cyrtorhinus lividipennis)种群发生动态的影响。【方法】试验分HH1处理组、亲本明恢63(MH63)组2个处理,每个处理设置3块试验田,定期调查不同处理田块内的褐飞虱及其2种天敌蜘蛛和黑肩绿盲蝽的数量。【结果】转基因水稻HH1对褐飞虱、蜘蛛和黑肩绿盲蝽的种群动态有一定程度的影响,但整个水稻生育期的试验结果显示,与亲本对照水稻MH63相比,转基因抗虫水稻HH1对上述3种非靶标昆虫均无显著差异。【结论】转cry1Ab/Ac基因水稻HH1的种植不会对褐飞虱及蜘蛛、黑肩绿盲蝽产生负面影响。[Objectives] To evaluate the effect of transgenic Bt rice on the population dynamics of the brown planthopper （BPH）, Nilaparvata lugens （Sthl） and two of their natural enemies in paddy fields. [Methods] Two treatments; namely the HH1 and MH63 rice varieties, were established, each with 3 replicates. We surveyed the quantities of brown planthopper, N. lugens and their two main natural enemies, including spiders and Cyrtorhinus lividipennis, in the different treatment crops. [Results] The HH1 rice crop exerted little influence on the abundance of N. lugens, spiders and C lividipennis, and the abundance of N. lugens, spiders and C lividipennis in HH1 rice fields was not significantly different compared to that in MH63 rice fields during the entire rice growth cycle. [Conclusion] Transgenic crylAb/Ac gene rice has no obvious negative effects on the quantities ofN. lugens, spiders and C. lividipennis in paddy fields.
