Boukar, O.Abdoulaye, TahirouTamo, M.Agrama, H.Tefera, H.Fatokun, C.A.Boahen, S.[A success tale on improving two legume crops in Africa]A success tale on improving two legume crops in Africa

The flower bud thrips, Megalurothrips sjostedti Trybom (Thysanoptera: Thripidae), is an economically important pest of cowpea in sub‐Saharan Africa. Varietal resistance is the most preferred, environmentally friendly, cost‐effective and sustainable option for controlling this pest. The objective ...


Togola, A.Boukar, O.Chamarthi, S.Belko, N.Tamò, M.Oigiangbe, N.Ojo, J.Ibikunle, M.Fatokun, C.[Evaluation of cowpea mini core accessions for resistance to flower bud thrips Megalurothrips sjostedti Trybom (Thysanoptera: Thripidae)]Evaluation of cowpea mini core accessions for resistance to flower bud thrips Megalurothrips sjostedti Trybom (Thysanoptera: Thripidae)

Flower bud thrips (Megalurothrips sjostedti) is one of the most damaging pests to cowpea in Africa and varietal resistance is one of the effective approaches to minimize the pest damage. Study was conducted to assess variability among 117 genotypes in addition to two resistant (Sanzisabinli and T...

Cowpea is an important grain legume crop in sub-Saharan Africa (SSA) where, on a worldwide basis, the bulk is produced and consumed. The dry savanna area of SSA is where cowpea is mostly grown under rain-fed conditions. The crop is therefore prone to drought which may occur early, mid and/or late...

A comparative analysis of farmers’ preferences on improved cowpea varieties was carried out based on the data obtained from farmers’ participatory varietal selection and questionnaire survey undertaken in south-eastern Niger and north-central Burkina Faso. The grain yield was consistently the mos...

The management of the fall armyworm Spodoptera frugiperda in maize field necessitates the use a big quantities of insecticides and sometimes the use of multiple types and formulations of chemicals. The use of insecticides in crops is associated with environmental risks and health hazards to both ...
