Cannabis essential oils unlock how camphor repels mosquitoes
From summer evenings to global disease prevention, mosquito repellents are a daily defense for billions of people, yet until now, scientists didn't fully understand how mosquitoes themselves perceive these "keep away" signals. A new study has pinpointed an odorant receptor that helps mosquitoes detect a repellent odor and steer away. The researchers found that activating this receptor switches on a dedicated neural pathway that can override the insects' attraction to human scents, producing clear avoidance behavior.
