摘要
通过室内试验和分析，建立了粘虫的发育速率与温度关系模型、发育的时间分布模型、产卵与成虫寿命及温度的关系模型等；应用计算机模拟技术，引入同龄组的概念，建立了适合于估测变温条件下粘虫种群动态的计算机模拟模型。运行结果表明，该模型可准确地模拟变温条件下粘虫的发育动态，并应用于田间粘虫预测和粘虫治理辅助决策。
In this study,some models (development rate model,development time distri-bution model,oviposition model and so on)in relation to armyworm were proposed after labo-ratory trials and analyses. Using computer simulating technique and cohort conception,the simulation model of armyworm population dynamics under variable temperatures was built. The results showed that the model (program) can simulate the development of armyworm ac-curately and can be used to predict the time of developmental stage as well as the number of population under field condition and make supplementary decision for armyworm manage-ment.
