  abstract = {{V}ariation at 12 microsatellite loci was investigated to assess the impact of the implementation of insecticide-treated bed nets ({ITN}s) on the genetic structure of {A}nopheles arabiensis in {S}imatou, a village surrounded by irrigated rice fields in the {S}ahelian area of {C}ameroon. {T}he {A}n. arabiensis population of {S}imatou was sampled twice before {ITN} implementation, and twice after. {E}ffective population size estimates ({N}-e) were similar across each time point, except for the period closely following {ITN} introduction where a nonsignificant reduction was recorded. {H}ence, we believe that {ITN} implementation resulted in a temporary bottleneck, rapidly followed by a demographic expansion. {T}he genetic diversity of the population was not significantly affected since different genetic parameters (allele number, observed and expected heterozygosities) remained stable. {L}ow estimates of genetic differentiation between the populations from {S}imatou and {L}agdo, separated by 300 km, suggested extensive gene flow among populations of {A}n. arabiensis in the {S}ahelian region of {C}ameroon. {A} decrease in the susceptibility to deltamethrin was observed following {ITN} introduction, but no kdr mutation was detected and a metabolic resistance mechanism is probably involved. {T}he temporary effect of {ITN}s on the genetic structure of {A}n. arabiensis population suggests that, to optimize the success of any control programme of this species based on {ITN}s, the control area should be very large and the programme should be implemented for a long period of time.},
