Worth knowing for global warm regions' travelers.
"Repellents are central to personal protection and to reducing transmission of mosquito-borne diseases. Although substantial effort has been devoted to identifying the sensory and molecular pathways underlying repellent detection, the diversity of reported modes of action has hindered the development of a unified framework. It is generally assumed that insects respond to repellents in a fixed, aversive manner. However, an unexplored possibility is how plastic the innate meaning of repellents may be. We present experiments testing whether the innate response of Aedes aegypti to DEET (the gold-standard repellent) can be shifted from aversion to attraction."
