Swatting mosquitos teaches them to avoid you

❝ In a paper published Jan. 25 in Current Biology, University of Washington researchers report that mosquitoes can in fact learn to associate a particular odor with an unpleasant mechanical shock akin to being swatted. As a result, they’ll avoid that scent the next time.

“Once mosquitoes learned odors in an aversive manner, those odors caused aversive responses on the same order as responses to DEET, which is one of the most effective mosquito repellents,” said senior author Jeff Riffell, a UW professor of biology. “Moreover, mosquitoes remember the trained odors for days…”

❝ “By understanding how mosquitoes are making decisions on whom to bite, and how learning influences those behaviors, we can better understand the genes and neuronal bases of the behaviors,” said Riffell. “This could lead to more effective tools for mosquito control.”

I can think of other relevant settings for the same process. Bigger animals. 🙂
