摘要
麦长管蚜是我国华北冬麦区的重要害虫,为制订出防治麦长管蚜的最优决策,我们进行了麦长管蚜实验种群的研究,分析了麦长管蚜与主要环境因子温度、湿度之间的关系,并建立了依赖于温度、湿度的麦长管蚜生长发育模型和内禀增长率模型.为预测麦长管蚜的发生动态提供了依据,为防治麦长管蚜最优决策的提出奠定了基础.
The laboratory studies on the relationships between the population dynamics, development rate of English grain aphid (Macrosiphum avenae. F.) and temperature-humidity have been carried out. a series of models for describing these relationships have been built up. Among these models, rhe model of the inate capacities for numerical increase dependent temperatur--humidity can be used to predicate the population dynamics of English grain aphid
