Potential Adoption of Integrated Pest Management Strategy for Suppression of Mango Fruit Flies in East Africa: An Ex Ante and Ex Post Analysis in Ethiopia and Kenya

Abstract

To sustain agricultural development in Africa, innovative strategies for addressing a myriad of biotic and abiotic constraints facing the agricultural systems must be established. One current biotic stress is the mango infesting fruit flies. In the effort to contain the widely spreading and damaging invasive species of tephritid fruit fly (Bactrocera dorsalis) (Hendel), an area-wide integrated pest management (IPM) program is being promoted in the horticultural sub-sector in sub-Saharan Africa. Such a new technology in which farmers have limited information before commercialization may have diffusion paths that are different from the often-assumed sigmoid (or “s”) shaped curve. We apply the descriptive and econometric analysis of ex ante and ex post integrated fruit fly management used by mango farmers in Kenya and Ethiopia. The results reveal that this technology has a relatively high adoption rate and high prospects for adoption growth in Kenya compared to Ethiopia in the near future.
