Mathematical Modeling of Occurrence and Population Density of Predatory Spider and Their Preys on Cotton Plants and Broad Bean in Two Governorates in Egypt
Abstract:The research presents a mathematical simulation of three kinds of pests and their predator for two plants: Cotton and broad bean. The study was applied in two regions in Egypt representing Upper Egypt and Delta. The study is based on similar field experimental results during the two successive years [2003][2004][2004][2005] in Qaha station-Qalubia governorate and seds station-Beni sweif governorate.Four models are introduced according to the plant and the geographical regions. The data were fitted to continuou… Show more
