摘    要:本文报道了转SCK+cry1Ac双基因抗虫水稻MSA和MSB对非靶标害虫褐飞虱Nilaparvata lugens 和白背飞虱Sogatella fucifera生物学及田间发生动态的影响。与亲本明恢86相比,MSA对两种飞虱若虫发育历期、初羽化成虫鲜重、羽化率、短翅率、成虫产卵量、卵受精率、单雌子代数及发育进度等生物学指标均无明显影响,而MSB虽然对多数指标影响不明显,但可以引起白背飞虱初羽化雌虫鲜重与短翅率显著下降,还引起褐飞虱初羽化雄虫鲜重明显减轻。在近距离(株间距约 8 cm)寄主选择实验中,褐飞虱对MSA和MSB无明显选择性,而白背飞虱若虫和成虫均明显趋向两种转基因水稻。田间小区实验表明MSB上的稻飞虱(主要为白背飞虱)密度一般低于亲本明恢86,但差异不显著,提示转基因水稻MSB引发非靶标害虫稻飞虱灾变的风险较小。

Abstract:The effects of two insect resistant transgenic rice lines MSA and MSB, containing both SCK and cy1Ac genes, on non target pests Nilaparvata lugens and Sogatella fucifera were investigated. Compared with the parent line Minghui 86, MSA showed no significant effect on the biological parameter of the non target insect pests, including nymphal duration, fresh weight of newly emerged adult, emergence rate, brachypterous rate, adult fecundity, rate of eggs fertilized, number of offsprings per female and their development. MSB rice did not markedly influence most of the biological indices of the two species of planthoppers although the fresh weight and brachypterous rate of emerged females of S. fucifera , and the weight of emerged males of N. lugens decreased significantly. It was observed that S. fucifera obviously preferred MSA and MSB to Minghui 86 in host selection behavior in short distance (about 8 cm) while N. lugens did not. However, the density of rice planthoppers (mainly S. fucifera ) in fields was generally lower on MSB than on Minghui 86, although the difference was not significant. These results suggested that the ecological risk of transgenic rice MSB causing the outbreak of rice planthoppers was small.
Keywords:Transgenic rice  SCK  cry1Ac  non  target pests  Nilaparvata lugens  Sogatella fucifera  ecological risk
