AB  - ackground: Aedes  aegypti is  vector  of  dengue  and  chikungunya  viruses  in  French  Guiana.  A strong  pyrethroid  resistance  has  posed  questions  on  the  impact  of  vector  control  and  resistance management. A prerequisite to improve those strategies is the investigation on population dynamics and  factors  which  influence  it.  Therefore,  we  have  implemented  a  population  genetic  study associated with deltamethrin resistance monitoring to provide further knowledge on these questions. Material  and  Methods: Two  sites  of  1  km²  in  Saint-Georges  de l’Oyapock  (SGO)  and  Cayenne (CAY)  were  prospected  for  mosquito  immature  stages  in  December  2013.  F0  females  were genotyped  for  13  microsatellites  and  for  the  knockdown resistance  associated  mutation  V1016I. Genetic  diversity  and  differentiation  indices  were  obtained  in  Arlequin  software.  Genetic  structure among  samples  was  tested  in  the  program  STRUCTURE.  Evolutionary  scenario  probabilities  and estimates were computed in DIY-ABC. Results: We detected the presence of two populations (k=2) congruent with each locality, with low but significant differentiation levels. Both populations exhibited similar effective population sizes and overall diversity. However, different evolutionary scenarios were obtained for each population. The V1016I kdr mutation  is almost  fixed  in  CAY  population while  SGO exhibited a  larger  proportion of heterozygotes. Conclusion: Genetic  differentiation  between  the  two  populations  suggests barriers  to  gene  flow that may limit the exchange of resistance alleles. Therefore, the expansion of insecticide resistance in  each  population  may  also  be  due  to  local  selective  pressure.  Additional  spatial  and  temporal investigations are being conducted to confirm this hypothesis.
