  abstract = {{B}ackground {T}wenty-seven villages were selected in southwest {B}urkina {F}aso to implement new vector control strategies in addition to long lasting insecticidal nets ({LLIN}s) through a {R}andomized {C}ontrolled {T}rial ({RCT}). {W}e conducted entomological surveys in the villages during the dry cold season ({J}anuary 2017), dry hot season ({M}arch 2017) and rainy season ({J}une 2017) to describe malaria vectors bionomics, insecticide resistance and transmission prior to this trial. {M}ethods {W}e carried out hourly catches (from 17:00 to 09:00) inside and outside 4 houses in each village using the {H}uman {L}anding {C}atch technique. {M}osquitoes were identified using morphological taxonomic keys. {S}pecimens belonging to the {A}nopheles gambiae complex and {A}nopheles funestus groupwere identified using molecular techniques as well as detection of {P}lasmodium falciparum infection and insecticide resistance target-site mutations. {R}esults {E}ight {A}nopheles species were detected in the area. {A}nopheles funestus s.s was the main vector during the dry cold season. {I}t was replaced by {A}nopheles coluzzii during the dry hot season whereas {A}n. coluzzii and {A}n. gambiae s.s. were the dominant species during the rainy season. {S}pecies composition of the {A}nopheles population varied significantly among seasons. {A}ll insecticide resistance mechanisms (kdr-w, kdr-e and ace-1 target site mutations) investigated were found in each members of the {A}n. gambiae complex but at different frequencies. {W}e observed early and late biting phenotypes in the main malaria vector species. {E}ntomological inoculation rates were 2.61, 2.67 and 11.25 infected bites per human per month during dry cold season, dry hot season and rainy season, respectively. {C}onclusion {T}he entomological indicators of malaria transmission were high despite the universal coverage with {LLIN}s. {W}e detected early and late biting phenotypes in the main malaria vector species as well as physiological insecticide resistance mechanisms. {T}hese data will be used to evaluate the impact of complementary tools to {LLIN}s in an upcoming {RCT}.},
