中文摘要:通过比较T1C-19菌株、T2A-1菌株、亲本非转基因明恢63菌株对褐飞虱种群密度的影响,本文评价了T1C-19(CYL1C)和T2A-1(CY2A)转基因水稻中苏云金芽孢杆菌原生质体的表达对褐飞虱的影响。田间调查发现,T2A-1、T1C-19和明恢63稻田中的褐飞虱种群密度相似。本文利用电穿透图技术进一步评价褐飞虱的摄食行为,研究发现,四个菌株对褐飞虱都很敏感,这表明转基因水稻和非转基因水稻对褐飞虱摄食行为的影响无显著差异。本文研究结果为中国稻田中,转Bt基因水稻对主要非靶标害虫褐飞虱不构成任何风险提供了新的证据。
外文摘要:The impact of the expression of Bacillus thuringiensis protoxins in the T1C-19 (cry1C) and T2A-1 (cry2A) transgenic rice strains on the brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae), was evaluated by comparing the population densities of N. lugens reared on the strains T1C-19 or T2A-1 or the parental non-Bt strain Minghui 63. Field investigations revealed that the population densities of N. lugens were similar among the T2A-1, T1C-19, and Minghui 63 rice fields. Further assessment of feeding behavior of N. lugens using electrical penetration graph (EPG) technology showed that all four strains are susceptible to N. lugens, which was evidenced by the non-significant difference in feeding behavior of N. lugens between the transgenic and non-transgenic rice plants. These results provide new evidence that Bt rice does not pose any risk on N. lugens which represents a key non-target pest species in Bt rice field in China.
