摘　　要：应用害虫种群系统控制的状态空间方程和作用因子添加分析法 ,模拟了 1 %印楝素乳油对黄曲条跳甲种群的控制作用 .结果表明 ,其控制机理主要表现为对成虫的忌避作用 ,尤其在种群发展初期 ,其显著的忌避作用降低了田间成虫数量和卵量 ,使种群数量明显降低 。Based on the natural population life tables of the striped flea beetle (SFB), Phyllotreta striolata F., the control effectiveness of azadirachtin on SFB was simulated and evaluated with state space equation and addition analysis method of insect pest population systemic control. The results showed that the control mechanism of azadirachtin on SFB population was its significant deterrent effect on the SFB adult. Especially at the initial stages of population development, azadirachtin demonstrated the strong impacts of reducing SFB adult and egg numbers, and subsequently significantly lowered the population densities and damage of SFB.
