Assessment of Cowpea (Vigna unguiculata (L.) Walp.) Mutant Lines for Drought Tolerance

open access: yesInternational Journal of Agronomy, Volume 2020, Issue 1, 2020., 2020
Cowpea provides the cheapest source of protein with an average range of protein content of 23–30%. However, cowpea growth, development, and yield are greatly affected by drought during flowering and pod filling in the sub‐Sahelian areas. The best way to cope with this situation is to develop drought‐tolerant cowpea varieties.

Stability of Sources of Resistance to Cowpea Aphid (Aphis craccivora Koch, Hemiptera: Aphididae) across Major Cowpea Production Zones in Ghana

open access: yesInternational Journal of Agronomy, Volume 2020, Issue 1, 2020., 2020
Aphids (Aphis craccivora Koch) are an important vegetative stage pest of cowpea in Africa. The use of resistant cultivars is among the best management option for this pest, but the success of this strategy is influenced by the stability of the resistant genotype to the cowpea aphid biotypes present in the major cowpea growing areas in a country.

Effects of Maruca vitrata multi-nucleopolyhedrovirus and neem oil, Azadirachta indica Juss on the eggs of the cowpea pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae) [PDF]

open access: yesInternational Journal of Tropical Insect Science, 2019
AbstractCowpea,Vigna unguiculata(L.) Walp., is the most cultivated and consumed legume in West Africa and is typically attacked by several insect pests, includingMaruca vitrata, leading to reduced yields. This study assessed under laboratory conditions the efficacy of neem oil andM. vitratamulti-nucleopolyhedrovirus (MaviMNPV) againstM.

Role of trichomes on leaves and pods for imparting resistance in chickpea [Cicer arientinum (L.)] genotypes against Helicoverpa armigera (Hübner) [PDF]

open access: yes, 2017
In chickpea, trichomes provide a potential resistance mechanism against Helicoverpa armigera (Hübner). The present study was conducted to evaluate the trichome density and trichome length on leaves and pods on nine genotypes of chickpea.
