中文摘要：
【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 （Stål）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。
英文摘要：
[Objectives] To evaluate the effect of transgenic Bt rice on the population dynamics of the brown planthopper (BPH), Nilaparvata lugens (Stål) 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 cry1Ab/Ac gene rice has no obvious negative effects on the quantities of N. lugens, spiders and C. lividipennis in paddy fields.
