Journal Article 1995

Autor: Jackai, L.E.N.

Cowpea varieties were evaluated for resistance to Maruca testulalis using differential insecticide sprays that provided a range of pest densities and crop damage. The latter was expressed as a pod evaluation index, Ipe, which uses the degree of pod production or pod load (PL) and pod damage (PD)....

Eighteen cowpea cultivars were screened for resistance to the legume pod borer, Maruca testulalis under field conditions at two locations (Mokwa and Ibadan) in Nigeria under unprotected and two types of insecticide protection levels. Unprotected plots gave zero yield due to their exposure to the ...

The aleyrodid Aleurodicus dispersus is reported from Nigeria. The first observation was made on cassava in early 1992 at several locations in Ibadan. A survey carried out in January 1993 revealed that several genera, many of them important food and ornamental crops, are food plants of the insect.

Wecreated a detailed model of the Maruca vitrata (F.) and cowpea [Vigna unguiculata (L.) Walp] system to study the possible evolution of resistance by the insect to transgenic insecticidal cowpea, which is under development. We focused on population dynamics and genetics in a region of west Afric...
