| 摘 要： | 棉铃虫Heliothis armigera(Hubner)是我国棉区重要害虫。当前迫切需要评价药剂防治棉铃虫的对策。 近年来,借助系统方法和数学模型评价害虫控制对策的报道日益增多。例如Conway等(1975)运用系统方法评价甘蔗沫蝉(Aeneolamia uaria saccharina)的几种控制对策,Shoemaker等(1979)对于危害橄榄的三种介壳虫和一种病害的三类控制对策的评价,

| Abstract: | An attempt is made in this present paper to seek a model which conforms to the econ-ecological principle on the basis of the current control methods. A deterministic static model given in it describes the strategy in the control of the 2nd brood cotton bollworm by use of chemical pesticides in Henshui areas, Heibei Province. Five components are contained in the model, such as the lint economic losses caused by the 2nd and 3rd broods, and the costs of control of the two broods and the midsummer aphis. The ob... |
