Abstract
Cowpea, until recently the major food legume in Ghana (in terms of area under cultivation) has been witnessing a decline in production at the expense of groundnuts. Among the factors leading to the decline are the havocs caused by insect pests and diseases with the former being of major importance.
The paper presents some of the systematic screening and testing procedures of both exotic and indigenous materials with the aim of evolving varieties that are not only high yielding but also resistant to a broad spectrum of these prevalent insect pests.
Résumé
Le Niebe, jusqu’à présent, le légume majeur de nourriture au Ghana (sous forme de la superficie de culture), témoigne un déclin en production aux dépens d’arachides. Parmi les facteurs conduisant a ce déclin sont les ravages occasionnés par l’insecte nuisible et par la maladie, celle-là étant d’une importance majeure.
Le résumé présente des criblures systématiques et des procedures d’essai de matériels à la fois exotiques et indigenes avant pour but de développer des variétés qui ne sont pas seulement de rendement à haute teneur mais aussi résistantes à un vaste spectre de ces insectes nuisibles et dominants.
