  abstract = {{S}tudying the behaviour and trophic preferences of mosquitoes is an important step in understanding the exposure of vertebrate hosts to vector-borne diseases. {I}n the case of human malaria, transmission increases when mosquitoes feed more on humans than on other animals. {T}herefore, understanding the spatio-temporal dynamics of vectors and their feeding preferences is essential for improving vector control measures. {I}n this study, we investigated the feeding behaviour of {A}nopheles mosquitoes at two sites in the {S}udanian areas of {S}enegal where transmission is low following the implementation of vector control measures. {B}lood-fed mosquitoes were collected monthly from {J}uly to {N}ovember 2022 by pyrethrum spray catches in sleeping rooms of almost all houses in {D}ielmo and {N}diop villages, and blood meals were identified as from human, bovine, ovine, equine and chicken by {ELISA}. {S}pecies from the {A}n. gambiae complex were identified by {PCR}. {T}he types and numbers of potential domestic animal hosts were recorded in each village. {T}he {H}uman {B}lood {I}ndex ({HBI}) and the {M}anly {S}election {R}atio ({MSR}) were calculated to determine whether hosts were selected in proportion to their abundance. {S}patio-temporal variation in {HBI} was examined using the {M}oran's index. {A} total of 1251 endophilic {A}nopheles females were collected in 115 bedrooms, including 864 blood fed females of 6 species. {A}n. arabiensis and {A}n. funestus were predominant in {D}ielmo and {N}diop, respectively. {O}f the 864 blood meals tested, 853 gave a single host positive result mainly on bovine, equine, human, ovine and chicken in decreasing order in both villages. {O}verall, these hosts were not selected in proportion to their abundance. {T}he human host was under-selected, highlighting a marked zoophily for the vectors. {O}ver time and space, the {HBI} were low with no obvious trend, with higher and lower values observed in each of the five months at different points in each village. {T}hese results highlight the zoophilic and exophagic behaviour of malaria vectors. {T}his behaviour is likely to be a consequence of the distribution and use of {LLIN}s in both villages and may increase risk of residual outdoor transmission. {T}his underlines the need to study the feeding host profile of outdoor resting populations and how domestic animals may influence malaria epidemiology in order to tailor effective malaria vector control strategies in the two villages.},
