This study was conducted to determine the effects of six different leguminous seeds (cowpea, white kidney bean, soybean cultivars Cheongja and Daepung, mung bean, and azuki bean) on the life history traits of the bean bug Riptortus pedestris (F.) (Hemiptera: Alydidae). The total developmental time from the first instar nymph to adult ranged from 18 to 25d; R. pedestris fed with white kidney beans were the slowest to develop. In addition, bugs fed with white kidney beans had the highest mortality (93%) and the shortest longevity (18 d). R. pedestris fed with cowpeas, soybeans, or azuki beans had high reproductive success, with the highest egg hatching success recorded in bugs fed cowpeas. The results suggest that cowpea may be a beneficial food source for the development and reproduction of bean bugs.
