摘　　要：实验室条件下,转cry1Ab/vip3H基因水稻G6H1对褐飞虱Nilaparvata lugens生长发育与繁殖的继代效应评价结果表明,不论是在苗期或是成株期,在各水稻品种上连续饲喂褐飞虱4代后,该虫各代的生长发育和繁殖参数都没有受到水稻品种的显著影响,即不论是在第1代、第2代还是第4代,取食G6H1与取食其非转基因亲本Xiushui 110相比,褐飞虱若虫的发育时间、成虫寿命和产卵量都没有显著差异。同时,2008年和2009年的田间调查结果表明,G6H1和Xiushui 110稻田间褐飞虱的若虫、成虫和成若虫总密度均无显著差异。Multi-generation effects of transgenic crylAb/vip3H rice G6H1 on development and reproduction of the brown planthopper （BPH）, Nilaparvata lugens, were evaluated under laboratory and field conditions. The laboratory results indicated that development and reproduction of the BPH were not affected by rice type, either in the rice seedling stage or the rice adult stage. Compared with BPH fed on non-transgenic parental rice Xiushui 110, nymph development, adult longevity and reproduction of BPH showed no significant difference in the 1^st, 2^nd and 4th generations, when BPH fed on G6HI, respectively. Field results of dynamics of BPH population showed that there was no significant difference in the average density of nymphs, adults or both between Xiushui 110 and G6H1 rice fields both in 2008 and 2009.
