Abstract:Growth and development of BruchoPhagus roddi (Gussakovsky) were studied using resistant and susceptible clones of alfalfa, Medicago sativa L. Developmental times for 5 stages (egg incubation, undefecated larva, defecated larva, pupa, emerging adult) were not significantly different between the 2 clones. Differences between alones for developmental mortality, adult longevity, and total life span also were nonsignificant. Thus, the resistant clone did not express antibiosis to the seed chalcid, and ovipositional nonpreference appears to be the sole operating mechanism of resistance to the alfalfa seed chalcid in the clones studied.
