Three insect groups, known from the literature, were confirmed to make up a seed pest complex in cowpea fields in Benin Republic (West Africa). Several species of heteropteran pod‐sucking bugs (PSBs), two lepidopteran species, namely Maruca testulalis (Geyer) and Cydia ptyehora (Meyrick) and the ...

The concentrations ofP, N, K, Mg, Cain cowpea (Vigna unguiculata (L.) Walp.) roots and shoots were assessed at 45 Days After Planting (DAP) in inoculated and uninoculated plants at sowing with rhizobia and Arbuscular-Mycorrhizal Fungi (AMF). Those of harvested seeds from inoculated and uninoculat...

Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a polyphagous insect pest that feeds on a variety of leguminous plantsin the tropics and subtropics. The contribution of host-associated genetic variation on population structure wasinvestigated using analysis of mitochondrial cytochrome oxidas...

Cowpea (Vigna unguiculata spp unguiculata) is adapted to the drier agro-ecological zones of West Africa where it is a major source of dietary protein and widely used as a fodder crop. Improving the productivity of cowpea can enhance food availability and security in West Africa. Insect predation ...

The larval parasitoid guild of the cowpea pod borer Maruca vitrata was studied on wild and cultivated host plants in Southern and Central Benin, West Africa. A total of eight parasitoids, seven of which belonging to the Hymenoptera: Braconidae, and one to the Diptera: Tachinidae, were observed ex...

Cowpea (Vigna unguiculata L. Walp.) is an important cash, food and nutritional security grain legume crop in the semi-arid regions of sub-Saharan Africa. However, its productivity is hampered by several biotic stress factors including numerous insect pests that infest and damage the crop at all i...

The interactions between cowpea and one of its key pests, Megalurothrips sjostedti (Trybom), were evaluated via a simulation model based on three modules building the core of the cowpea growth model, i.e. the time-varying distributed delay, the functional response acquisition function, and the me...

The objective of this study was to investigate on how the interactions between the microbial syrnbionts (AMF+rhizobia) and the rnycopesticide M. anisopliae can affect the cowpea production in varied agro ecological zones of Cameroon. Cowpea of the Bafia local cultivar was grown from 1999 to 2004 ...
