CIAT (International Center for Tropical Agriculture) works in collaboration with hundreds of partners to help developing countries make farming more competitive, profitable, and resilient through smarter, more sustainable natural resource management. We help policymakers, scientists, and farmers respond to some of the most pressing challenges of our time, including food insecurity and malnutrition, climate change, and environmental degradation. Our global research contributes to several of the United Nations’ Sustainable Development Goals, and [...]

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 practices and botanical pesticides. For host plant resistance, we identified varios sources of resistance from the CIAT phaseolus vulgaris core collections as well as material held in the Tanzania bean germplasm collections. Some of these sources are now in use to transfer resistence to adapted lines as well as elite breeding lines. With cultural practices, we observed previously that mulches reduced plant damage resulting from BSM attack and we set up further trials to gain a greater understanding of the mechanism of grass mulches and stabilized soil temperature at a lower level below the ambient temperature and the non-mulched treatments. This was reflected in adventitious root development and plant survival. Botanical pesticides such as aqueous extracts of neem and persian lilac seed powder and Tephrosia leaves also reduced BSM infestation and damage. These practices could be used in the development of IPM strategies for small scale farmers systems to reduce BSM pressure and increase bean yields.
