Type: article
Abstract: Eleven species of wild legumes were collected during May and November at Okayama Prefecture, Japan. Of these legumes, adults of the azuki bean weevil Callosobruchus chinensis (L.) were found on Vigna angularis (WILLD.) OHWI & OHASHI var. nipponensis (OHWI) OHWI & OHASHI and Dunbaria villosa (THUMB.) MAKINO. Adults also emerged from the seeds of the 2 legumes. When a pair of newly emerged adults from a stock culture was provided with the seeds of 11 wild legumes at 25°C, 70±5% RH, adults emerged from 4 wild legumes: V. angularis var. nipponensis, D. villosa, Amphicarpaea edgeworthii BENTH var. japonica OLIVER and Pueraria lobata (WILLD.) OHWI. On both V. angularis var. nipponensis and D. villosa, adult emergence was about 85%. On A. edgeworthii and P. lobata, however, it was much lower than 20%. On the former 2 legumes, the developmental period was nearly equal to that of adults from the azuki bean, Vigna angularis (WILLD.). On the latter legumes, it was more than twice as long. Adult longevity decreased in the following sequence; V. angularis (control), V. angularis var. nipponensis, D. villosa, A. edgeworthii and P. lobata. Total number of eggs laid by a female emerging from V. angularis var. nipponensis was more than 70, similar to that of a female emerging from the azuki bean. Females from D. villosa, A. edgeworthii and P. lobata laid much fewer eggs than those from the azuki bean. Results indicate that V. angularis var. nipponensis and D. villosa are host plants for the azuki bean weevil as food.
