Secrets of insect repellent DEET being uncovered.Posted: October 3, 2013
“Until now, no one had a clue about which olfactory receptor insects used to avoid DEET. Without the receptors, it is impossible to apply modern technology to design new repellents,” said Professor Anandasankar Ray, an entomologist at the University of California, Riverside, who led the study.
“Ir40a and its related proteins are conserved not only in flies and mosquitoes, but also in many other insects that are human and plant pests. Our findings could lead to a new generation of cheap, affordable repellents that could protect humans, animals and, in the future, our crops as well,” Professor Ray said.
“We could find truly novel repellents that have remarkable properties such as large-scale spatial protection and long-term protection.”
