随着转基因抗虫棉在中国商业化种植推广,对非鳞翅目生物可能产生的影响存在很多争议。中国从1997年推广Bt抗虫棉,其商业化生产已达15年,为研究棉田主要害虫种群变化以及靶标害虫对Bt抗虫棉的抗性,笔者对长江棉区和黄河棉区6个省65个村农户进行了面对面访谈。棉花是中国重要的经济作物和纤维作物,其生长过程中遭受多种害虫危害,其中最严重的是棉铃虫、红铃虫、棉蚜及棉叶螨等。上世纪90年代,中国棉花主产区棉铃虫连续爆发,造成严重的经济损失。自1997年引进美国转基因抗虫棉品种33B和99B至今,转基因抗虫棉在中国的种植历史已超过15年,并
With the commercialization of transgenic Bt cotton in China, there is much controversy about the possible impact on non-Lepidopteran organisms. China has promoted Bt insect-resistant cotton from its commercial production in 1997 for 15 years. In order to study the change of major pest populations in cotton fields and the resistance of target pests to Bt cotton, six provinces 65 village households conducted face-to-face interviews. Cotton is an important economic crop and fiber crop in China. Its growth is endangered by many pests. The most serious ones are cotton bollworm, pink bollworm, cotton aphid and cotton spider mite. In the 1990s, the continuous burst of cotton bollworm in the main cotton producing area of China caused serious economic losses. Since the introduction of the transgenic cotton varieties 33B and 99B of the United States since 1997, the transgenic cotton has been planted in China for more than 15 years and has
