分析2005～2008年东疆棉蚜的发生规律及其与气象因子的关系,将棉蚜在棉田的活动时间划分为5月、6月、7～8月3个阶段,运用湿温比构建棉蚜日发生等级的预测模型,运用气温构建棉蚜旬、月发生等级的预测模型。2009年棉蚜发生等级的检验结果表明,本文所模拟的预测模型准确率较高,可用于东疆地区棉蚜发生等级的预报。
Based on the analysis of the occurrence regularity of cotton aphid and its relationship with meteorological factors from 2005 to 2008 in Inner Mongolia, the activities of cotton aphid in cotton field were divided into three phases: May, June and July to August. Aphid day generation level prediction model, the use of temperature to build cotton aphid ten month, monthly occurrence level prediction model. The test results of the grade of cotton aphid in 2009 showed that the prediction model simulated in this paper has high accuracy and can be used to predict the occurrence level of cotton aphid in eastern Xinjiang.
