The common bean, Phaseolus vulgaris, is a vital crop in East and Central Africa serving as a food and cash crop and playing an important nutritional role by providing between 20 and 25% of proteins. Unfortunately bean yields have consistently remained lower than potential yield. One reason being ...

On-station and on-farm studies were carried out in 2008 during the long rains (March – May), in Taita region, Kenya, to assess the effect of various soil fertility regimens on bean stem maggot (BSM) (Ophiomyia spp.) and black bean aphid (BBA) (Aphis fabae) incidences. These studies aimed at gathe...

Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...

In our efforts to develop strategies for the manegement of bean steam maggots (bean fly) (Ophiomyia spp; Dipteras Agromyzae) in small scale farmers systems, we focus on options that are available and sustainable within the farming environment. These include host plant resistance, cultural practic...

Several chemicals were tested at both the on-farm and exptl. levels to control major seed-transmitted root diseases in the Great Lakes region of Africa. Seed treatments to control the beanfly in Burundi were combined to assess the efficiency of combined treatments against fungi and insects. Indiv...

Damage by insect pests, inter alia, is considered the liming factor of bean production in Africa. This paper reviews the current status of insect pests of beans, focusing on their ecology and management, as well as the potential for integrated pest management (IPM) approaches in subsistence fanni...

Bean Stem Maggot (BSM) is a serious production problem in many African countries. In South Africa, the problem receives very little research and extension attention. This study set out to assess the magnitude of the BSM problem at Greytown during the 1995 season. Using a split-plot trial, split f...
