| 摘 要： | 苜蓿斑蚜Therioaphis trifolii(Monell)是危害苜蓿最为严重的害虫之一。通过室内饲养,选用5个不同的苜蓿品种,测定了不同苜蓿品种上苜蓿斑蚜存活率及生殖力的影响。结果表明:苜蓿斑蚜在不同苜蓿品种的世代平均存活率以固原紫花最高,达97.83%,阿尔冈金最低,为72.73%。以存活率和内禀增长率作为测定抗性的指标,供试品种对苜蓿斑蚜抗性的大小依次为德国大叶﹥阿尔冈金﹥宁苜1号﹥固原紫花﹥金皇后,与田间抗性鉴定结果基本相近。

| Abstract: | The aphid Therioaphis trifolii（Monell） is one of the most serious pests of alfalfa.The survival rate and fecundity of T.trifolii on five alfalfa varieties was investigated under laboratory conditions.Survival rates were highest（97.83%） on Guyuan Zihua,and the lowest（72.73%） on A er Gangjin.Based on the innate capacity of increase（rm） and survival rate,the relative resistance of alfalfa varieties to this pest was,in order of increasing resistance,German Daye A er Gangjin Ningmu yi hao Guyuan Zihua Jinhuanghou.This result was supported by field observations. |
