Abstract
Twenty cowpea cultivars were evaluated for resistance to nine different insect pests in field plantings. Cultivars differed significantly in degree of susceptibility to Aphis spp., thrips, the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), the velvetbean caterpillar, Anticarsia gemmatalis Hübner, the southern green stink bug, Nezara viridula (L.), and the cowpea curculio, Chalcodermus aeneus Boheman. The velvetbean caterpillar was the most abundant lepidopterous pest, and a positive linear relationship between population density and the resultant estimated defoliation was noted. In the cowpea curculio evaluation, percentage of damaged pods correlated significantly with both the number of punctures on peas and number of eggs and curculio larvae. Chances of finding a cultivar resistant to several of these insect pests were poor.
