| 摘 要： | 本文采用二次通用旋转组合设计方法，研究了草间小黑蛛、小花蝽、龟纹瓢虫３种天敌与棉铃虫共存系统的动态捕食量数学模型，对捕食量模型分析可以了解棉铃虫种群密度与天敌复合种群密度之间的关系及对捕食量的影响、各类天敌种群间的交互作用。同时还建立了各类天敌数量增长的子模型。为棉田棉铃虫防治策略提供理论依据。

| Abstract: | By applying quodratic common rotation regression design,an experiment fordeveloping the dynamic predation models of Erigonidium graminicola(Sundevall),Oriusminutus Linnaeus and Propylaea japonica(Thunberg),the dominant natural enemyspecies,on cotton bollworm[Helicoverpa armigera(Hubner)]in their coexistent systemsin caged cotton field were conducted.The effects of different density combinations of natu-ral enemies on their predatory amounts, interactions among these natural enemies and op-timum predator:prey ratio were analysed.The submodel for population development ofdifferent natural enemies were also established. |
