禹州小麦吸浆虫发生程度与气象因素的关系

Relationships Between Occurrence Degree of Wheat Midge and Meteorological Factor

小麦吸浆虫的发生程度与温度、湿度、日照密切相关。适宜的气温、湿度及日照条件以及2005年土壤中虫源基数较高,是2006年禹州吸浆虫发生严重的主要原因。依据温度条件,建立了吸浆虫发生期预测方程;依据温湿条件,建立了发生量预测方法。此外,还提出了麦播期、孕穗期(蛹期)和抽穗期(成虫期)的防治方法。

The occurrence degree of wheat midge has close relationship with temperature, humidity and sunshine. The suitable temperature, humidity and sunshine conditions, adding the high midge source radix in 2005, which are the mean reasons for Yuzhou midge damage. The forecasting equation of midge origin time is established according temperature condition; and the forecasting method of generating capacity is established according temperature and humidity conditions. The precaution of wheat seed - time, booting stage （pupal stage） and tassel stage （imago stage） is proposed.
