摘要
利用新乡、灵宝、太康、南阳、虞城等县１９８０～１９８９年间共计１５年次的棉红蜘蛛发生资料，建立了基于Ｆｕｚｚｙ相关分析的棉红蜘蛛发生程度综合决策模型。对模型的预测效果检验表明，模型与历史实测结果的符合率最高达８６．７０％，１９９０～１９９１年对太康、郑州和南阳棉田红蜘蛛发生程度实际预测准确度达１００％。
The cotton spider mite,(Tetranychus cinnabarinus)is one of the most important insect pests of cotton in Henan province.The systematic data of population dynamics for the mite from 1980 to 1989 in Xinxiang and other counties were accumulated,based on that and some environmental factors(temperature and rainfall),a fuzzy model with a high precision for prediction of cotton spider mite was founded.
