摘　　要：目前在防治麦红吸浆虫的药效试验中,尚缺乏穗期防治的试验方法。本试验采用黄色粘板监测麦红吸浆虫成虫的发生动态,在小麦齐穗期,用不同剂量20%呋虫胺可溶粒剂喷雾对麦红吸浆虫进行防治。结果表明,20%呋虫胺可溶粒剂用量为20、25和30g/667m2时对麦红吸浆虫的防治效果可达90%以上。本试验为今后制定麦红吸浆虫穗期防治的药效试验准则提供了科学依据。Till now,there is no efficient experimental method for the control of the wheat midge,Sitodiplosis mosellana during the wheat heading stage.Yellow sticky traps were used to monitor the population dynamics of S.mosellana adults.Three doses of 20% dinotefuran SG spraying during wheat heading stage were used to control S.mosellana.The results showed that the control efficacy of 20% dinotefuran SG at the doses of 20,25 and 30 g/667m^2 exceeded 90%.This study may provide the scientific basis for the criterion for controlling S.mosellana at the wheat heading stage.
