摘　　要：[目的]掌握不同寄主植物对豌豆蚜生长发育及繁殖的影响规律。[方法]在(23±1)℃、光照时间16h、相对湿度80%的人工气候箱条件下,组建了豌豆蚜在4种寄主植物上的生命表,统计出种群内禀增长率(rm)、净增殖率(R0)、平均世代周期(T)、种群加倍时间(t)和周限增长率(λ)等种群动态参数。[结果]在蚕豆、豌豆、苜蓿、红豆草4种寄主植物上,豌豆蚜的发育历期存在显著差异,内禀增长率rm分别为0.263 2、0.261 9、0.224 3、0.217 1。[结论]豌豆蚜在蚕豆上的适应度和嗜食性最好,并且繁殖速度最快。[Objective]To investigate the effects of four different host plants on development and reproduction of Acyrthosiphon pisum（Harris）.[Method]Life tables were constructed at the constant temperature of（23±1）℃,relative humidity 80%,and illumination time of 16 hours and the intrinsic rate of increase（rm）,net reproductive rate（R0）,finite rate of increase（λ）,mean generation time（T） and double population time（t） were estimated under four treatments.[Result]The influences of the host horsebean,garden pea,luceren and sainfain on the developmental duration were observed.The results indicated that the intrinsic rates of increase were 0.263 2,0.261 9,0.224 3 and 0.217 1,respectively.[Conclusion]A.pisum had best adaptability and fastest breeding rates on horsebean.
