Evidence-based advice on timing and location of tsetse control measures in Shimba Hills National Reserve, Kenya

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.本采采蝇（tsetse fly）定位数据集被用于探究卫星衍生环境因子与气象数据是否能够解释肯尼亚夸莱县辛巴山国家保护区周边淡足舌蝇（G. pallidipes）的种群丰度。研究结果表明，在距离该保护区不足1.0公里的范围内，采采蝇种群数量始终处于较高水平。超出该距离阈值后，当经历30天的降雨增多且后续植被绿度（归一化差异植被指数，Normalized Difference Vegetation Index，NDVI）上升时，采采蝇种群数量会随之增长。但若降雨持续时长超过一个月，采采蝇种群数量则会开始下降。
