摘　　要：为明确春小麦间作豆科绿肥对麦长管蚜及其天敌的影响,2021年在甘肃武威对春小麦不同种植方式下麦长管蚜及其天敌发生动态进行了监测调查。结果表明,春小麦间作毛叶苕子、春小麦间作箭筈豌豆和春小麦单作3种种植方式下麦长管蚜田间消长动态相似,但春小麦间作毛叶苕子和春小麦间作箭筈豌豆的麦长管蚜始见期推迟,且麦长管蚜种群数量显著低于春小麦单作(p<0.05),寄生蜂、草蛉、蜘蛛种群数量显著高于春小麦单作(p<0.05)。表明春小麦间作毛叶苕子、箭筈豌豆等豆科绿肥能够延缓麦长管蚜发生、降低麦长管蚜种群数量,增加寄生蜂、草蛉、蜘蛛等天敌数量,具有良好的生态调控功能。The effects of intercrop ping spring wheat with green manure legumes on Sitobion avenae and its natural enemies were unknown. In this study, the population dynamics of S. avenae and its natural enemies under different planting patterns of spring wheat were monitored in Wuwei, Gansu Province in 2021. The results indicated that the population dynamics of S. avenae were similar under three planting patterns of spring wheat. However, the onset of S.avenae was delayed in spring wheat intercropped with hairy vetch and spring wheat intercropped with common vetch, of which the population of S. avenae was significantly lower than that of the spring wheat monocropping(p <0.05). The population of parasitoid wasps, lacewings, and spiders in the two intercropping treatments was significantly higher than that in the spring wheat monocropping system(p<0.05). This suggested that spring wheat intercropped with hairy vetch or common vetch could delay the occurrence of S. avenae, reduce the population of S. avenae, and increase the number of natural enemies including parasitoid wasps, lacewings, and spiders, which possessed a good ecological regulation potential.
