| 摘 要： | Biology of the aphid Therioaphis maculata was studied on alfalfa （Medicago sativa L.）, including four resistant （Mesa-Sirsa, CUF101, Baker and Lahontan） and two susceptible （ARC and Caliverde） alfalfa cultivars, and one of the most cropped Brazilian cultivars, Crioula. Under controlled conditions, antibiosis （i.e., reduced longevity, fecundity and increased mortality of the aphid） was observed mainly on the resistant alfalfa cultivars, except on Lahontan. Crioula seemed to be tolerant to aphids. Present data support geographic limitation usage of cultivars, and we suggest Baker and Mesa-Sirsa as sources of antibiosis, and provide biological information of a tropical T. maculata biotype on alfalfa.
