Rearing the legume pod borer, Maruca testulalis, Geyer (Lepidoptera: Pyralidae) on artificial diet

Autor: Jackai, L.E.N. Raulston, J.R.

Several diets were tested for rearing the legume pod borer, Maruca testulalis (Geyer). After initial selection of a soyflour‐based diet, further research was conducted to determine whether cowpea flour could be substituted for soyflour. Three levels of cowpea flour were tested; 25, 38 and 50 g of...

The potential for controlling postflowering pests of cowpea, Vigna unguiculata Walp., using neem, Azadirachta indica A. Juss

Autor: Jackai, L.E.N. Inang, E.E. Nwobi, P.

The insecticidal activity of neem, Azadirachta indica A. Juss., was tested on two major cowpea pests using different concentrations of aqueous extracts, and powders of both neem seed and kernel. The pests were larvae of Maruca testulalis Geyer (Lepidoptera: Pyralidae), the legume pod borer and Cl...

Cowpea plant architecture in relation to infestation and damage by the legume pod borer, Maruca testulalis Geyer (Lepidoptera: Pyralidae) 1. effect of canopy structure and pod position

Autor: Oghiakhe, S. Jackai, L.E.N. Makanjuola, W.A.

The effects of cowpea, Vigna unguiculata (L.) Walp. canopy structure and pod position in relation to infestation and damage by the legume pod borer, Maruca testulalis Geyer were investigated. Defoliated cultivars sustained significantly less infestation and damage (P < 0.05) than those undefoliat...

Podwall toughness has no effect on cowpea resistance to the legume pod borer

Autor: Oghiakhe, S. Jackai, L.E.N. Makanjuola, W.A.

The possibility of the involvement of pod wall toughness in the resistance of cowpea, Vigna unguiculata (L.) Walp., to the legume pod borer, Maruca testulalis was studied. The toughness of non-intact and intact pod wall increased with age, but the rate varied at different growth stages of the pod...
