转crylAb/vip3H+epsps基因粳稻对非靶标害虫稻叶蝉田间种群的影响

转基因作物可能带来的风险之一是对非靶标生物尤其是非靶标植食者产生潜在的影响。本研究采用吸虫器取样法,通过在浙江长兴2地点3年的试验评价了新型抗虫/耐除草剂转crylAb/vip3H+epsps基因粳稻(G6H1)及其亲本对照(秀水110,XSll0)对稻叶蝉田间种群动态的影响。结果表明:叶蝉类主要有黑尾叶蝉Nephotettixcincticeps(Uhler)、二点叶蝉Cicadula丘sc分%w(Stal)和电光叶蝉DeltocephalusdorsalisMotschulsky组成,其中黑尾叶蝉是优势种。虽然3种叶蝉的种群密度随着地点和年份的不同有所不同,但是转基因水稻对3种叶蝉种群密度...

Summary:转基因作物可能带来的风险之一是对非靶标生物尤其是非靶标植食者产生潜在的影响。本研究采用吸虫器取样法,通过在浙江长兴2地点3年的试验评价了新型抗虫/耐除草剂转crylAb/vip3H+epsps基因粳稻(G6H1)及其亲本对照(秀水110,XSll0)对稻叶蝉田间种群动态的影响。结果表明:叶蝉类主要有黑尾叶蝉Nephotettixcincticeps(Uhler)、二点叶蝉Cicadula丘sc分%w(Stal)和电光叶蝉DeltocephalusdorsalisMotschulsky组成,其中黑尾叶蝉是优势种。虽然3种叶蝉的种群密度随着地点和年份的不同有所不同,但是转基因水稻对3种叶蝉种群密度的年度变化均没有显著性影响。少数年份,黑尾叶蝉成虫、若虫及其两者总密度的时间动态在转基因水稻和对照田之间存在差异,大多数年份,趋势一致且无显著差异(P〉0.05)。另外,二点叶蝉和电光叶蝉种群的时间动态在转基因水稻和对照田之间也相似。综合评价认为,本供试转基因水稻品系G6H1对稻田稻叶蝉种群无明显的负面影响。

One of the risks posed by transgenic crops is their potential effects on non-target orgamsms, especially non-target herbivores. In this study, experiments were conducted at two sites in Changxing, Zhejiang, eastern China in three years to assess the effects of transgenic crylAb/vip3H + epsps japonica rice (G6H1) and its non-transgenic rice (Xiushui 110, XSll0) on rice leafhoppers using the vacuum- suct
