摘要： 利用1988-2005年互助县麦茎蜂羽化盛期和气象资料分析表明:气象条件是影响麦茎蜂羽化盛期的主要因子之一,影响麦茎蜂羽化盛期早晚的关键期是上年10月和当年1月,主要因子是1月平均气温、1月降水量、1月20cm平均土温、上年10月平均气温,且1月平均气温、土温比1月降水量、上年10月平均气温的影响显著;气候变暖的阶段性趋势使麦茎蜂对麦类等作物的危害程度有加重的趋势;羽化盛期模式的预测值与实测值相差在1~3d,模式可为当地提高药剂防治麦茎蜂危害效果及防治决策提供参考。

Abstract: Through analyzing the wheat stem sawfly emergence booming stage and meteorological data of Huzhu county from 1988 to 2005,it showed that the weather conditions was one of the factor of emergence booming stage delayed and the critical period of emergence booming stage was the last October and January,the main factors were the average January temperature,January precipitation,20cm average soil temperature in January,the average temperature in October last year,and the January average temperature.The soil temperature had significant effect than the January precipitation,average temperature in October last year.With the trend towards global warming,it made the harmful levels of wheat stem sawfly for crops was increasing trends.The difference between predicted and measured values of eclosion pattern was 1-3 days,and the model might be a scientific reference for the local chemical control of wheat stem sawfly.

Key words: Climatic change, Wheat stem sawfly, Emergence booming stage
