| 摘 要： | 本文建立了红圆蚧(Aonidiella aurantii)与3种寄生蜂:盾蚧长缨蚜小蜂(Encarsia citrina)、岭南黄蚜小蜂(Aphytis lingnanensis)和印巴黄蚜小蜂(Aphytis melinus)相互作用的系统模型。按红圆蚧的面积大小分成3种类型,分析了三维系统和四维系统在不同红圆蚧大小分布条件下,系统的动态变化。确定了寄生物共存和相互排斥的边界条件,为红圆蚧的生物防治决策提供理论依据。

| Abstract: | This paper constructed an interaction model of Aonidiella aurantii and its three parasites: Encarsia citrina, Aphytis lingnanensis, Aphgtis melinus. In the model the host is devided into 3 types according to scale area:s(above 0. 55mm2) , t(0. 39-0. 55mm2 ),u (below 0. 39mm2);through changing the value of (s, t,n) and the attacking rate of parasites(a,b,c) ,we analysed the dynamics of 3-dimension systems(two parasite -one host) and 4 - dimension systems (three parasite - one host) , determined the boundary conditions for parasites to compete exclusively or to coexist. It provided a theoretical guidance to the strategy of biological control of Aonidiella aurantii. |
