摘要： 用Weibull函数为骨架，组建了褐飞虱成虫的具有年龄特征的存活率和生殖率模型。经检验，适合性显著。褐飞虱的雌成虫存活率随温度的升高而降低，期望寿命缩短，但在水稻不同生育期间的差异不大。生殖量在26℃左右时及抽穗期较大。尽管在温度较高时存活率低，产卵量小，但由于生殖高峰提前出现，就使得实际种群增长率仍较高。从而认为加入各种参数的年龄特征，比只考虑其总量特征，在组建害虫种群预测和管理系统模型时，更具有积极意义。

Abstract: Based on the Weibull's function, the models of survival rate and fecundity of adult brown plant hopper(Nilaparvata lugens Stal) have been made along with their age distribution traits. The models are fitable according to the paper's results. The survival rate decreases as the temperature increases, but there is no obvious difference between each developmental stage of rice. The peak of fecundity occurs at 26 ℃ and at heading stage of rice. The increasing rate of the population is higher at a little higher temperature than at the biological optimum temperature. It is because the reproductive peak comes earlier. The results indicated that the age distribution of survivalrate and fecundity is more important than total children number in making system model of pest population dynamicforecasting and management.
