摘      要：Background:Changes of land cover modify the characteristics of habitat,host-vector interaction and consequently infection rates of disease causing *** this paper,we report variations in tsetse distribution patterns,abundance and infection rates in relation to habitat types and age in the Maasai Steppe of northern *** Africa,Tsetse-transmitted trypanosomiasis negatively impacted human life where about 40 million people are at risk of contracting the disease with dramatic socio-economical consequences,for instance,loss of livestock,animal productivity,and ***:We trapped tsetse flies in dry and wet seasons between October 2014 and May 2015 in selected habitats across four villages:Emboreet,Loiborsireet,Kimotorok and Oltukai adjacent to protected *** collected include number and species of tsetse flies caught in baited traps,PCR identification of trypanosome species and extraction of monitored Normalized Difference Vegetation Index(NDVI)data from Moderate Resolution Imaging Spectrometer(MODIS).Results:Our findings demonstrate the variation of tsetse fly species abundance and infection rates among habitats in surveyed villages in relation to NDVI and host *** have shown higher tsetse fly abundance in Acacia-swampy ecotone and riverine habitats for Emboreet and other villages,*** abundance was inconsistent among habitats in different *** was highly infested with Glossina swynnertoni(68%)in ecotone and swampy habitats followed by ***(28%)and ***(4%)in riverine *** the remaining villages,the dominant tsetse fly species by 95%was *** in all *** vivax was the most prevalent species in all infected flies(95%)with few observations of co-infections(with *** or ***).Conclusions:The findings of this study provide a framework to mapping hotspots of tsetse infestation and trypanosomiasis infection and enhance the communities to plan for effect
