Yale Finds Garlic Compound Blocks Insect Mating in 43-Food Study

Diallyl disulfide, a garlic compound identified by Yale scientists, completely stopped mating and egg laying in fruit flies and also curbed reproduction in mosquitoes and tsetse flies.
Tests across 43 fruits and vegetables showed garlic alone had the strong effect, and follow-up experiments found taste—not smell—was what suppressed reproductive behavior.
The compound activates TrpA1-linked bitter-taste neurons in the insects’ taste organs, triggering avoidance and gene-expression changes tied to satiety, especially in females.
Published in Cell, the findings suggest widely grown, low-cost garlic could become a natural tool to control disease-carrying and agricultural pest insects.

As the natural repellent market nears $7 billion, can this garlic discovery create a plant-based solution that truly rivals DEET's power?
