Genome sequence of the Asian Tiger mosquito,Aedes albopictus, reveals insights into its biology, genetics, and evolution

Significance Aedes albopictus is a highly adaptive species that thrives worldwide in tropical and temperate zones. From its origin in Asia, it has established itself on every continent except Antarctica. This expansion, coupled with its ability to vector the epidemic human diseases dengue and Chikungunya fevers, make it a significant global public health threat. A complete genome sequence and transcriptome data were obtained for the Ae. albopictus Foshan strain, a colony derived from mosquitoes from its historical origin. The large genome (1,967 Mb) comprises an abundance of repetitive DNA classes and expansions of the numbers of gene family members involved in insecticide resistance, diapause, sex determination, immunity, and olfaction. This large genome repertory and plasticity may contribute to its success as an invasive species.
