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。
Through the laboratory experiment and analysis, the model of the relationship between the developmental rate and the temperature of armyworm, the time distribution model of development, the relationship model between the oviposition and adult longevity and temperature were established. By using computer simulation technology, the concept of peer group was introduced to establish a suitable Computer Simulation Model for Estimating the Population Dynamics of Mythimna Separatea under Variable Temperature Conditions. The results show that the model can accurately simulate the development of armyworm under variable temperature conditions and is applied to the prediction of armyworm in the field and the aid decision-making for armyworm control.
