| 摘 要： | 利用新疆塔城1989～1996年8年的麦双尾蚜Diuraphis noxia (Mordvilko)发生程度与16个气象因子进行相关性分析，通过逐步回归筛选因子，确定麦双尾蚜发生量预测模型：logY=84100-0.1033RH5-0.0253R5，其中：Y为麦双尾蚜发生百株蚜量；RH5为5月份的相对湿度(%)；R5为5月份的降水量(mm)。应用该模型预测1997～1998年麦双尾蚜的发生程度，与实际发生情况基本吻合。

| Abstract: | A model for predicting abundance of the Russian wheat aphid (RWA)，Diuraphis noxia (Mordvilko)，was derived from regression analysis between the actual occurrence of RWA observed and the 16 weather parameters，1989-1996 in Tacheng，with screening of the parameters step by step. The model can be expressed as: logY=8.41-0.1033RH5 - 0.0253R5，where Y is the number of RWA on 100 wheat tillers，RH5 and R5 are the relative humidity (%) and rainfall (mm) in May respectively in the year to be predicted. The model is simple and practical，and showed reliability to certain extent when used to predict occurring levels of RWA in 1997 and 1998. |
