Abstract
An experiment was carried out during 1983-84 at the CIAT experimental Station in Palmira, Colombia, to identify the damage caused by insects to the reproductive structures of the common bean plant. Four planting dates and the varieties Diacol-Calima, ICA-Pijao, and VRB-81023 were used. The lepidopterous Heliothis virescens and Pseudoplusia includens (Noctuídae), Strymon melinus (Hübner) (Lycaenidae), Estigmene acrea (Drury) (Arctiidae), Maruca testulalis (Geyer) (Pyralidae), Epinotia aporema (Wasingham) and Cydia fabivora (Meyrick) (Olethreutidae), leaf beetles (Coleoptera: Chrysomelidae) and stink bugs (Hemiptera: Pentadomidae) were found attacking buds, flowers, and pods. M. testulalis was one of the commonest insects found attacking pods from formation until physiological maturity. H. virescens perforated buds and pods from formation to physiological maturity while larvae of P. includens scraped the pod surfaces. E. aporema and C. fabivora penetrated pods of al' maturity groups including harvest-ready pods. In general, the chrysomelids appeared in all of the reproductive stages of the 3 varieties except for harvest maturity, although their damage to filling pods was restricted to secondary attacks in wounds that other insects, such as P. includens or virescens, opened.
