Journal Article 1991

Autor: Jackai, L.E.N.

Two resistance screening assays were developed for evaluating cowpea Vigna unguiculata (L.) Walp resistance to the legume pod borer (MPB), Maruca testulalis Geyer, one of the most intractable pest problems of this important food crop. The first assay, the dual-choice arena test (DCAT), provided a...

Journal Article 1990

Autor: Jackai, L.E.N.

A laboratory screening method was developed for evaluating resistance of cowpea, Vigna unguiculata (L.) Walp, to Clavigralla tomentosicollis Stål. The technique uses dry cowpea seeds, which were judged better than fresh seeds or fresh pods, to identify protracted nymphal development and high coho...

As research on food crops intensifies in the tropics, the spotlight is being increasingly focused on the development of varieties with resistance to pests and diseases. Much of the time, money and patience needed to conduct research on host plant resistance (HpR) is spent on the development of me...

A novel method for screening cowpea varieties for resistance to the postharvest insect pest Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) was compared to conventional screening techniques at the International Institute for Tropical Agriculture (IITA) laboratory in Ibadan, Nigeria. The new...
