摘　　要：近年来,随着气候变暖和农药的大量使用,大豆蚜虫成为夏大豆田的主要害虫。2013—2014年对山东济南夏大豆试验田的大豆蚜虫进行定点、定期调查,同时进行2.5%溴氰菊酯乳油防治效果研究。结果表明,山东产区大豆蚜虫始发期为7月中下旬,盛发期为8月上旬至9月中旬,消退期为9月下旬;始花期喷施2.5%溴氰菊酯可有效控制大豆蚜的发生,并显著提高大豆产量。In recent years,with the climate warming and the use of a large number of pesticides,soybean aphid has become the main insect pest of summer soybean. The fixed and regular survey was carried out in summer soybean test field in Jinan,Shandong during 2013-2014. At the same time,the control effects of 2. 5% deltamethrin EC were researched. The results showed that the beginning period of soybean aphid incidence was in mid-to-late July,the full incidence period was from the first ten days of August to the middle ten days of September,and the declining period was in the last ten days of September. In addition,spraying 2. 5% deltamethrin EC at the beginning flowering stage could effectively control the occurrence of soybean aphid in the field and significantly increase the yield of soybean in the harvest period.
