This tsetse locational data was utilized to investigate if satellite-derived environmental factors and weather data could explain the abundance of G. pallidipes around the Shimba Hills National Reserve in Kwale County, Kenya. Our findings revealed that tsetse fly numbers were consistently high within a distance of less than 1.0 km from the reserve. Beyond that distance, tsetse fly numbers increased after 30 days of increased rainfall and the following increase in vegetation greenness (NDVI). However, if rainfall persisted for more than a month, tsetse fly numbers started to decline.
