供试棉田的系统调查资料显示，６１９２，中棉１２和冀棉１１等３个棉花品种上的棉蚜和卵形异绒螨幼螨的种群消长符合Ｌｏｇｉｓｔｉｃ模型，棉蚜被幼螨寄生的寄生率变化符合Ｗｅｉｂｕｌ－Ⅰ模型。通过模型参数和实测资料对比得知，该幼螨具有随不同棉花品种上的棉蚜种群变化而变化的调节能力，同时得知６１９２棉花品种较抗蚜，冀棉１１较感蚜。 Systematic survey data of the tested cotton fields showed that the populations of cotton aphid and oviposition mites on 6192, 12 cotton and 11 cotton jams met the logistic model, and the cotton aphid was parasitized by the parasitoids Rate changes in line with Weibul-Ⅰ model. According to the comparison of the model parameters and measured data, the larvae have the ability of regulating the changes of cotton aphid populations on different cotton varieties. At the same time, the 6192 cotton varieties are more resistant to aphid and cotton than cotton aphid.
