A team from Australia and Switzerland takes a look at the genomics of Aedes aegypti and Ae. albopictus mosquito populations in the Indo-Pacific region, uncovering distinct genetic differentiation patterns in the two invasive mosquito species. As they report in PLOS Neglected Tropical Diseases, the researchers did double-digest restriction-site associated (ddRAD) sequencing-based genotyping on nearly 500 Ae. aegypti or Ae.
