摘　　要：为研究影响大豆蚜虫田间种群动态的关键因素,本研究结合2016-2018年气温和降水量资料,分析大豆蚜虫田间动态与气温和降水量的总体关系。结果表明:气温对大豆蚜虫田间种群动态影响较大,以20℃为节点起伏,气温越高大豆蚜虫发生量越大;降水量对大豆蚜虫田间种群动态影响不明显。In order to study the key factors affecting field population dynamics of soybean aphids,the overall relationship between field dynamics of soybean aphids and temperature and precipitation was analyzed based on the data of temperature and precipitation from 2016 to 2018.The results showed that temperature had a great influence on the population dynamics of soybean aphids in the field,at 20℃ was the nodes fluctuate.The higher the temperature was,the greater the occurrence of soybean aphids was.The effect of precipitation on the population dynamics of soybean aphids was not obvious.
