摘　　要：以亲本闽恢3301(MH3301)为对照,利用年龄-龄期两性生命表研究转cry1Ab水稻(MF86)在感染水稻瘤矮病毒情况下对电光叶蝉种群的影响.结果表明:与取食未感病MH3301相比,取食未感病MF86的电光叶蝉1、5龄若虫期及总寿长显著延长;与取食感病MH3301相比,取食感病MF86的电光叶蝉若虫期显著缩短,内禀增长率和净增殖率均显著升高;无论水稻感病与否,取食MF86的电光叶蝉繁殖率和存活率均比取食MH3301的种群较高.种群预测结果表明,在相同的感病状态下,取食MF86的电光叶蝉较取食MH3301的种群增长更快.The effects of transgenic cry1Ab rice(MF86)infected with Rice gall dwarf virus(RGDV)on the population parameters of Recilia dorsalis were studied by the age-stage two-sex life table,with the non-transgenic counterpart(MH3301)as the control.Compared with R.dorsalis feeding on healthy MH3301,R.dorsalis feeding on healthy MF86 demonstrated significantly prolonged durations of 1 st and 5 th instar nymph,and life span.Compared with R.dorsalis feeding on RGDV-infected MH3301,the nymph durations of R.dorsalis feeding on RGDV-infected MF86 were significantly shortened,while the intrinsic rate and net reproductive rate were significantly increased.Whether infected with RGDV or not,the fecundity and survival rates of R.dorsalis feeding on MF86 were higher than those feeding on MH3301.The population projection showed that under the same infected condition,the population of R.dorsalis feeding on MF86 increased much more rapidly than that feeding on MH3301.
