title: Data from: High-throughput sequencing of transposable element insertions suggests adaptive evolution of the invasive Asian Tiger Mosquito towards temperate environments

description: Invasive species represent unique opportunities to evaluate the role of
 local adaptation during colonization of new environments. Among these
 species, the Asian tiger mosquito, Aedes albopictus, is a threatening
 vector of several human viral diseases, including dengue and chikungunya,
 and raises concerns about the Zika fever. Its broad presence in both
 temperate and tropical environments has been considered the reflection of
 great “ecological plasticity.” However, no study has been conducted to
 assess the role of adaptive evolution in the ecological success of Ae.
 albopictus at the molecular level. In the present study, we performed a
 genomic scan to search for potential signatures of selection leading to
 local adaptation in one-hundred-forty field-collected mosquitoes from
 native populations of Vietnam and temperate invasive populations of
 Europe. High-throughput genotyping of transposable element insertions led
 to the discovery of more than 120,000 polymorphic loci, which, in their
 great majority, revealed a virtual absence of structure between the
 biogeographic areas. Nevertheless, 92 outlier loci showed a high level of
 differentiation between temperate and tropical populations. The majority
 of these loci segregate at high insertion frequencies among European
 populations, indicating that this pattern could have been caused by recent
 adaptive evolution events in temperate areas. An analysis of the
 overlapping and neighbouring genes highlighted several candidates,
 including diapause, lipid and juvenile hormone pathways.
