Genetic studies on host-plant resistance to bean fly (Ophiomyia spp.) and seed yield in common bean (Phaseolus vulgaris) under semi-arid conditions.
Bean fly (Ophiomyia spp.) is a major pest of common bean (Phaseolus vulgaris L.) throughout eastern and southern Africa. In the semi-arid areas, apart from drought, the insect pest is reported to cause high crop losses up to 100%, particularly when drought occurs and under low soil fertility. Host-p...
