摘　　要：应用作用因子组建的生命表和干扰作用控制指数,分析了吡虫啉、木虱净分别与叶面肥的混剂对橄榄星室木虱自然种群的控制效果。结果表明:木虱净+多微核苷酸、吡虫啉+多微核苷酸、木虱净+15%FeSO4、吡虫啉+15%FeSO4、木虱净和啉虫啉等6个处理区中橄榄星室木虱种群趋势指数均小于1,种群数量呈下降趋势,而对照处理区种群数量以6.39倍的速度增长。干扰作用控制指数显示,木虱净+多微核苷酸、吡虫啉+多微核苷酸、木虱净+15%FeSO4、吡虫啉+15%FeSO4、木虱净和吡虫啉处理区种群数量分别是对照区的3.18%、3.71%、3.85%、4.75%、6.23%和6.49%,取得了很好的防治效果。混配植物叶面肥比单一使用杀虫剂控制橄榄星室木虱种群效果好。The life table grouped by various factors and the interference index of population control were used as the bas-ic sampling parameters to evaluate the controlling effects of compounds of foliage fertilizer mixed with imidacloprid and Lambda-cyhalothrin respectively on Pseudophacopteron canarium. Results showed that the population indices of P.canari-um were all smaller than 1 in the six test areas, which are Lambda-cyhalothrin and imidacloprid mixed with micro-nucle-otide respecitively, Lambda-cyhalothrin and imidacloprid mixed with 15% green vitriol respecitively, Lambda-cyhalothrin and imidacloprid treated separately. Besides, the trends of population numbers are declining in all six test ar-eas. In the contrast, the population numbers increased tremendously with the speed of 6. 39 times in the control area. Comparing to the control area, the interference indices of population control for the six test areas were 3.18%,3.71%, 3.85%,4.75%,6.23% and 6.49%, respectively. It is suggested that mixture with foliage fertilizer displayed better in-sect-control effect than the single insecticides applied on the trees.
