  abstract = {{B}ackground: {A} better understanding of the ecology and spatial-temporal distribution of malaria vectors is essential to design more effective and sustainable strategies for malaria control and elimination. {I}n a previous study, we analyzed presence-absence data of {A}n. funestus, {A}n. coluzzii, and {A}n. gambiae s.s. in an area of southern {B}enin with high coverage of vector control measures. {H}ere, we further extend the work by analysing the positive values of the dataset to assess the determinants of the abundance of these three vectors and to produce predictive maps of vector abundance. {M}ethods: {P}ositive counts of the three vectors were assessed using negative-binomial zero-truncated ({NBZT}) mixed-effect models according to vector control measures and environmental covariates derived from field and remote sensing data. {A}fter 8-fold cross-validation of the models, predictive maps of abundance of the sympatric {A}n. funestus, {A}n. coluzzii, and {A}n. gambiae s.s. were produced. {R}esults: {C}ross-validation of the {NBZT} models showed a satisfactory predictive accuracy. {A}lmost all changes in abundance between two surveys in the same village were well predicted by the models but abundances for {A}n. gambiae s.s. were slightly underestimated. {D}uring the dry season, predictive maps showed that abundance greater than 1 bite per person per night were observed only for {A}n. funestus and {A}n. coluzzii. {D}uring the rainy season, we observed both increase and decrease in abundance of {A}n. funestus, which are dependent on the ecological setting. {A}bundances of both {A}n. coluzzii and {A}n. gambiae s. s. increased during the rainy season but not in the same areas. {C}onclusions: {O}ur models helped characterize the ecological preferences of three major {A}frican malaria vectors. {T}his works highlighted the importance to study independently the binomial and the zero-truncated count processes when evaluating vector control strategies. {T}he study of the bio-ecology of malaria vector species in time and space is critical for the implementation of timely and efficient vector control strategies.},
