Abstract
A tiny cylindrical cavity extending entirely through the long axis of the seed resulted from attack of cow pea seeds by the larva of Melanagromy chalcosoma Spencer. In laboratory and field experiments, planting insect-damaged seeds of the cultivars Emma, Saunders Upright, and SVS-47 (-a) resulted in: reduced germination and retarded radicle development, depressed rate and extent of seedling emergence from the soil, and an increased proportion of seedlings with abnormal cotyledons, as compared to seeds planted which were not damaged by the fly. Seed of Emma, ostensibly because of its larger size, showed superior performance in the presence of seed damage as compared to the other two cultivars used.
