摘要： 在不同温度条件下，对豆蚜、豌豆蚜、豌豆修尾蚜3种蚜虫发育历期、产仔量、寿命的影响进行了比较试验，结果显示，豆蚜发育起点为（6.05±；1.44）℃，有效积温为（106.63±；9.19）日度；豌豆蚜发育起点为（5.69±；1.72）℃，有效积温（113.01±；2.98）日度；豌豆修尾蚜发育起点为（4.02±；2.22）℃，有效积温为（131.45±；29.84）日度，3种蚜虫最适发育温度为19~23℃，在19℃时产仔量最多，其中以豌豆蚜的繁殖能力最强，达69.5头。

Abstract: The developmental zero,effective accumulative temperature(EAT),and fecundity for three species,namely,Aphis craccivora,Acyrthosiphon pisum and Megoura japonica,were studied.The results showed that the developmental zero of A.craccivora,A.pisum and M.japonica were(6.05±1.44)℃,(5.69±1.72)℃,and(4.02±2.22) ℃.The EAT of the three species were(106.63±9.19),(113.01±2.98),and(131.45±29.84)℃ day-degree respectively.The range of fit temperature for three species is 19-23℃.Under 19℃ all of three species can lay more number of nymphae than that at other temperatures and A.pisum has the highest fecundity among the three species,69.5 nymphae on average laid by a female in her whole life.
