Genome of Asian Tiger Mosquito Sequenced

October 28, 2015

Researchers have revealed the genome of the Asian tiger mosquito, Aedes albopictus, in a paper published by the Proceedings of the National Academy of Sciences (PNAS).

A. albopictus' genome is big, the largest mosquito genome sequenced so far, with swaths of repetitive DNA. The researchers identified large groups of genes involved in mosquito immunity, insecticide resistance, sex determination, smell, and survival in harsh environmental conditions. Such genes may reveal secrets to the species' success as a global invader and carrier for viruses like chikungunya. Some sections also resemble viral genomes, supporting the idea that the coevolutionary roots of the mosquitoes and the flaviviruses run deep.
