The influence of roads on the fine-scale population genetic structure of the dengue vector Aedes aegypti (Linnaeus).
Dengue is endemic in tropical and subtropical countries and is transmitted mainly by Aedes aegypti. Mosquito movement can be affected by human-made structures such as roads that can act as a barrier. Roads can influence the population genetic structure of Ae. aegypti. We investigated the genetic str...
