Three bruchid species - Callosobruchus chinensis (L.), C. maculatus (F.) and C. analis (F.) - infest mungbean in the field and during storage. Major damage, however, results from the insect infestation during storage. Bruchid larvae bore into seeds and feed on the cotyledons in which they pupate. Insect feeding reduces the quality and quantity of mungbean seeds. Drying of seeds briefly at 55 to 60 C kills the bruchids inside the seeds. Drying seeds to moisture contents of below 9.5% before storage reduces bruchid infestation considerably. Coating seeds with 5 to 10 ml of vegetable oils per kg of seeds, fumigation with phostoxin, or mixing seeds with insecticides of low mammalian toxicity such as malathion, DDVP or pyrethrins protect stored seeds from bruchid infestation. Sex pheromones have a potential to monitor pest incidence, thereby enabling control measures to be taken in time to reduce further losses. One black gram and one Vigna glabrescens accessions are highly resistant to C. chinensis; however, utility of these resistance sources in breeding bruchid-resistant mungbean cultivars by conventional breeding techniques is limited due to genetic barriers. A new mungbean accession with a moderate level of bruchid resistance is now available. This is expected to hasten the breeding of bruchid-resistant mungbean cultivars. [AS]
