| 摘 要： | 2009-2011年,在四川峨眉对大棚模拟条件下角倍蚜春季的迁飞数量及其与气象因子的关系进行观察分析,结果表明春迁蚜的迁飞活动与天气条件密切相关,在迁飞期内,当日平均气温≥9℃、最高气温≥13℃、平均相对湿度≤80％,春迁蚜开始迁飞；当日平均气温≥15 ℃、最高气温≥22 ℃、日照时数≥7 h、平均相对湿度≤65％,春迁蚜大量迁飞.在迁飞初期和中期,春迁蚜迁飞数随气温升高而增加.当天气条件适宜时,春迁蚜日迁飞数量的变化为单峰型,前期和末期低、中期高；当迁飞期内遭遇激烈降温,日迁飞数量波动较大,呈双峰或多峰型,同时迁飞期延长、迁飞率和单位面积迁飞量下降.相关分析与主成分分析结果:春迁蚜日迁飞数与平均气温、日最高气温和日照时数呈极显著正相关(P＜0.001),与平均相对湿度、最小相对湿度呈显著负相关(P＜0.05),与日最低气温和降水量相关性不显著(P＞0.1)；表明温度和湿度是影响春迁蚜迁飞的关键因子,日照次之.
