摘　　要：抗虫转基因水稻的培育和利用为水稻害虫控制提供了一条最为有效、经济的途径,但抗虫转基因水稻是否安全一直备受瞩目,以近期发表的文献为基础,从稻田蜘蛛、天敌昆虫和无尾两栖动物等三方面,综述抗虫转基因水稻对天敌的影响。已有研究表明,抗虫转基因水稻对捕食性天敌生物学特征无明显不利的生态效应,但会影响其部分基因的表达;抗虫转基因水稻对寄生性天敌个体数量等参数影响较大,但并非Bt毒蛋白直接影响所致,而可能因为靶标害虫种群和体内营养的变化,此方面有待进一步研究。The breeding and use of Insect-Resistant Transgenic Rices( IRTRs) provide a useful and economic approach for the integrated pest management(IPM) of rice insect pests. However,people have pay great attention to the safety of IRTRs. Here,we view the effects of IRTRs on enemies summarizing the research progress in this fields through three parts: spiders,enemy insects and Anura. Researches indicated that IRTRs had no obvious adverse ecological effects on the biological characteristics,but affected the expression of some genes of the predatory enemies.IRTRs had a great influence on the individual number and other parameters of parasitic enemies. The reason may be due to changes in the target pest population and nutrition,rather than the direct impact of Bt toxin protein,this study should be focused on in the future.
