摘要
本文建立了稻纵卷叶螟及其主要捕食性天敌相互作用的捕食——被捕食关系的微分方程数学模型,并利用稻纵卷叶螟实验种群生命表及广东省四会县田间调查消长数据估计模型参数,进行计算机模拟。模拟结果基本反应出了稻纵卷叶螟及其捕食性天敌的发生趋势。
In this paper, we made up a series of continuity equations to describe the predator-prey relation of rice leaf-roller (Cnaphalocrocis medinalis Guenee) and its major natural enemies, which are considered mainly including paddy spiders, Carabidae, Staphylinidae and Coccinellidae. Furthermore, we simulated this predator-prcy system by using the laboratory population life table of rice leafroller and the data of its population fluctuation in the field of Sihui County, Guangdong Province.
