  abstract = {{B}ackground: {T}o implement an {I}nsecticide {R}esistance {M}anagement ({IRM}) strategy through a randomized controlled trial (phase {III}), 28 villages were selected in southern {B}enin. {N}o recent entomological data being available in these villages, entomological surveys were performed between {O}ctober 2007 and {M}ay 2008, before vector control strategies implementation, to establish baseline data. {M}ethods: {M}osquitoes were sampled by human landing collection (16 person-nights per village per survey per village) during 5 surveys. {M}osquitoes were identified morphologically and by molecular methods. {T}he {P}lasmodium falciparum circumsporozoite indexes were measured by {ELISA}, and the entomological inoculation rates ({EIR}s) were calculated. {M}olecular detection of pyrethroid knock down resistance ({K}dr) and of insensitive acetylcholinesterase were performed. {R}esults: 44,693 mosquitoes belonging to 28 different species were caught from {O}ctober 2007 to {M}ay 2008. {A}mong mosquitoes caught, 318 were {A}n. gambiae s.s., 2 were {A}n. nili, 568 were {A}n. funestus s.s., and one individual was {A}n. leesoni. {EIR} was 2.05 +/- 1.28 infective bites per human per 100 nights on average, of which 0.67 +/- 0.60 were from {A}n. funestus and 1.38 +/- 0.94 infective bites were from {A}n. gambiae. {I}mportant variations were noted between villages considering mosquito density and malaria transmission indicating a spatial heterogeneity in the study area. {T}he kdr allelic frequency was 28.86% in {A}n. gambiae s.s. on average and significantly increases from {O}ctober 2007 (10.26%) to {M}ay 2008 (33.87%) in {M} molecular form of {A}n. gambiae s.s. {A}ce 1 mutation was found in {S} molecular of {A}n. gambiae s.s at a low frequency (< 1%). {C}onclusion: {T}his study updates information on mosquito diversity and malaria risk in rural villages from south {B}enin. {I}t showed a high spatial heterogeneity in mosquito distribution and malaria transmission and underlines the need of further investigations of biological, ecological, and behavioral traits of malaria vectors species and forms. {T}his study is a necessary prerequisite to cartography malaria risk and to improve vector control operations in southern {B}enin.},
