摘　　要：应用生命表方法分析吡虫啉、木虱净、稻虱净3种化学农药对橄榄星室木虱的控制效果。结果表明:吡虫啉、木虱净、稻虱净和对照的种群趋势指数分别为0.414 8,0.832 8,4.990 8,6.392 5。说明吡虫啉和木虱净处理区的橄榄星室木虱种群数量呈下降趋势,稻虱净和对照区的橄榄星室木虱种群数量以4.990 8和6.392 5倍的速度增长;吡虫啉、木虱净和稻虱净的干扰作用控制指数分别为0.064 9,0.130 3和0.780 7。表明吡虫啉和木虱净施用区种群数量相当于对照区的6.49%和13.03%,取得了很好的防治效果;稻虱净施用区种群数量是对照的78.07%,不是防治橄榄星室木虱的理想药剂。Control effects of imidacloprid, beta-cypermethrin and buprofezin on Pseudophacopteron canarium were analyzed by the method of life table. The results showed that population trend indexes （I） of imidacloprid, beta-cypermethrin, buprofezin and the control were 0.414 8,0. 832 8,4.990 8 and 6.392 5 respectively,which indicated the population of Pseudophacopteron canarium declined in the plots treated by imidacloprid and beta-cypermethrin, but that in the plots treated by buprofezin and the control rose by 4.990 8 and 6.392 5 times respectively. The interference index of population control （IIPC） of imidacloprid,beta-cypermethrin and buprofezin were 0. 064 9,0.130 3 and 0. 780 7 respectively,which indicated that the population in the plots treated by imidacloprid and beta-cyperrnethrin were only 6.49% and 13.03% of that in the control plots,so the control effects were good;population in the plots treated by buprofezin was 78.07% of that in the control plots,so its control effect was not ideal.
