Validation and dissemination of bio intensive eco-friendly management strategies for thrips-a critical constraint to cowpea production in Africa.
Grain legumes are the second most important food crop in the region cultivated by small-holder farmers. Thrips such as Bean Flower thrips (Megalurothrips sjostedti) are key biotic constraints inflicting 20- 100% yield loss. Pesticides are commonly applied to manage these pests with as high as 8 – 10 applications in a cropping season. The project focuses to assess impact of thrips infestation to grain legume productivity in the region and develop and disseminates effective IPM tools based on the use of entomopathogenic fungi; thrips attractant and conservation of natural enemies such as parasitoids in Eastern Africa. The evaluation of “Lure and kill” strategies for thrips with entomopathogens and thrips attractant, identification of the aggregation pheromone for Bean flower thrips undertaken are innovative and unique areas of research in the project.
