Bean Leaf Beetle (Ootheca spp.) (Coleoptera: Chrysomelidae) Management via Planting Timing and Insecticides

Abstract: Bean leaf beetles (Ootheca spp.) (Coleoptera: Chrysomelidae) are one of Africa’s most important pests of the common bean (Phaseolus vulgaris L.). Roots, leaves, floral parts, and young pods are all attacked, leading to a considerable loss in grain yield. In Uganda, there are no comprehensive prescribed management strategies for bean leaf beetles, but farmers typically try to control the pest by delaying bean crop sowing, and to a lesser extent, using insecticides. Although farmers have consistently implemented… Show more

“…Combining imidacloprid soil drench with cypermethrin foliar spray reduced insect pests' populations except for bean leaf beetles and caterpillars. Generally, insecticides have been reported to reduce insect pest populations and increase grain yield [25][26][27][28], including bean leaf beetles [20]. Low insect populations as a result of soil drench and foliar spray combinations may be attributed to imidacloprid unique ability to combat a variety of insect pests, when applied either as a soil drench or a foliar spray since it is easily translocated in the xylem [29].…”
