Could catnip become the new DEET?

Northwestern Now The common plant shows promise as a new natural insect repellent New collaborative research from Northwestern University and Lund University may have people heading to their backyard instead of the store at the outset of this year’s mosquito season. Often used as an additive for cat toys and treats due to its euphoric and hallucinogenic effects on cats, catnip has also long been known for its powerful repellent action on insects, mosquitoes in particular. Recent research shows catnip compounds to be at least as effective as synthetic insect repellents such as DEET. But until now, the mechanism that triggered insects’ aversion to this common member of the mint family was unknown. In a paper published today in the journal Current Biology, a team of researchers from Northwestern and Lund universities report finding the underlying receptors that contribute to the mosquitoes’ aversive reaction.

Catnip s Effectiveness as a Natural Mosquito Repellent Linked to Irritant Receptor Activation

Catnip may be used as a natural insect repellent. [Gallio lab / Northwestern] While catnip is a common herb that is often used in cat toys and treats due to its euphoric and hallucinogenic effects on our domesticated felines it has also long been known for its powerful repellent action on insects, and mosquitoes in particular. An international team of scientists at Northwestern University and at Lund University has now identified a receptor that is responsible for the aversive effect that catnip and its nepetalactone ingredient, has on these insects. The studies, reported in Current Biology, showed that catnip and nepetalactone activate the insect TRPA1 receptor to trigger this aversion, but have no effect on the human TRPA1 receptor.

Three Northwestern professors named Sloan Research Fellows

Northwestern Now Young researchers are ‘rising stars driving the research frontier’ Three Northwestern faculty members mathematician Xiumin Du, chemist Julia Kalow and mathematician Ilya Khayutin have each been awarded a prestigious 2021 Sloan Research Fellowship from the Alfred P. Sloan Foundation. The three are included among the 128 outstanding early-career scholars to be recognized for achievements and potential to bring substantial contributions to their scientific fields. Awarded annually, this years’ class draws from a diverse range of 58 institutions across the U.S. and Canada. Xiumin Du The two-year $75,000 fellowship is one of the most competitive and prestigious awards available to young researchers, and past fellows have gone on to become some of the most decorated experts in their field.
