Background:The rapid and unplanned urbanization of African cities is considered to increase the risk of urban malaria *** present study objective was to assess factors influencing the spatio-temporal distribution of Anopheles gombioe *** in the city of Yaounde,***:All water bodies were checked once every 2 months for the presence of mosquito larvae from March 2017 to May 2018 in 32 distrias of ***-chemical characteristics including the size,depth,turbidity,pH,temperature,conductivity,sulfates,organophosphates,hydrogen peroxide(H2O2),conductivity,iron and calcium were recorded and analyzed according to anopheline larvae presence or *** resolution satellite images from landsat sentinel Enhanced Thematic Mapper were used for spatial mapping of both field and environmental *** and multivariate logistic regression models were used to identify variables closely associated with anopheline larvae ***:A total of 18696 aquatic habitats were checked and only 2942 sites(15.7%)contained anopheline larvae.A high number of sites with anopheline larvae(>69%)presented late instar larvae(L3,L4 and pupae).Anopheline mosquito larvae were sampled from a variety of breeding sites including puddles(51.6%),tire prints(12.9%),wells(11.7%)and drains(11.3%).Bivariate logistic regression analyses associated anopheline larvae presence with the absence of predators,absence of algae,absence of vegetation and depth of less than 1 ***,turbidity,organophosphates,H2O2 and temperature were significantly high in breeding sites with anopheline larvae than in breeding sites without these larvae(P<0.1).Anopheline species colleaed included ***(91.1%)and *** s.s.(8.9%).GIS mapping indicated a heterogeneous distribution of anopheline breeding habitats in the city of *** cover analysis indicated high variability of the city of Yaounde's ***:The data confirms adaptation of
