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 ,模拟植物保护剂保卫德对黄曲条跳甲种群控制作用 ,结果表明 ,其控制的生态学机理主要表现在对成虫的忌避作用 ,尤其是在种群发展的初期 ,由于其显著忌避作用 ,降低了田间成虫数量和卵量 ,使其种群数量明显降低 。 Based on the natural population life tables of the striped flea beetle (SFB), Phyllotreta striolata F., the control effectiveness of plant protector BIOACT T35 on SFB was simulated and evaluated using state space equation and addition analysis method of insect pest population systemic control. Results showed that the ecological control mechanism of BIOACT T35 on SFB population was it′s deterrent effect significant on the adult. Especially in the initial stages of population development, the SFB adult and egg numbers reduced notably due to the strong deterrent effect of BIOACT T35, then, the population numbers and the harm of SFB population reduced significant.
