Abstract
Sixteen taxa in the genus Vigna were compared for susceptibility to attack by Callosobruchus rhodesianus (Pic.) under laboratory conditions. Ovipositional response, adult emergence and their development periods differed significantly between the species. Although oviposition took place on all the Vigna taxa at varying levels, the bruchid was unable to develop successfully on four of the 16 taxa Investigated. V. vexillata var. angustifolia, V. vexillata var. vexillata, V. oblongifolia and V. luteola were resistant to attack.
Résumé
La susceptibilité de seize espèces de haricot du genre Vigna a 1’infestation par le charançon Callosobruchus rhodesianus a été étudiée au laboratoire. L’oviposition, l’eclosion des oeufs ainsi que la durée totale du développement ont varié en fonction de l’espèce de haricot. Bien que l’oviposition a été enregistrée pour toutes les espèces, quatre ont cependant empêché tout développement ultérieur. Les espèces V. vexillata var. angustifolia, V. vexillata var. vexillata, V. oblongifolia and V. luteola se sont montrées résistantes a l’attaque de ce charançon.
