摘　　要： 为了有效地防治棉叶蝉,促进华南棉花发展,研究了10个陆地棉品种田间棉叶蝉数与温度、降水的关系,建立了11个陆地棉棉叶蝉数量气象条件预报模型,其中3个分别可以较准确地预报抗虫棉95-1、石家庄428 2个品种和10品种平均单株棉叶蝉数。品种间棉叶蝉发生轻重对温度、降水的反应不同,为了提高预报精确度,每个品种应各建立一个棉叶蝉预报模型。 In order to control cotton leafhopper effectively and promote the development of cotton on southern China,the study researched the relationship between the number of leafhopper of 10 G.hirsutum L varieties and temperature,rainfall on the field and set up 11 meteorological forecast models for the number of leafhoppers and three of which were more accurate on prediction the number of leafhopper of kangchongmian95-1,Shijiazhuang,428 and the average number per plant of 10 varieties.Because there is a difference in the respond to the weather between the varieties,a single meteorological forecast model should be established respectively in order to improve forecast accuracy.
