Yale researchers found that the sulfur-containing compound diallyl disulfide—formed as garlic is crushed—activates the fly’s TrpA1 receptor and dramatically reduces mating and egg-laying in fruit flies and other disease-carrying species like tsetse flies and mosquitoes, suggesting garlic could inform pest-reduction strategies.
A Yale-led study shows garlic does more than repel pests: when fruit flies and two mosquito species taste the garlic compound diallyl disulfide, it activates the TrpA1 receptor and triggers bitter/ fullness signals that stop feeding and, crucially, reproduction. The effect is taste-based (not smell) and wasps lacking TrpA1 are unaffected. This points to garlic-derived compounds as targeted, safer pest-control tools, and the researchers also introduce phytoscreen as a simple method to screen plant substances for behavioral effects on insects.
Yale-led researchers screened 43 fruits and vegetables and found that garlic’s diallyl disulfide can disrupt mating and egg-laying in fruit flies, Aedes mosquitoes, and tsetse flies by acting on the taste receptor TrpA1, offering a cheap, safe avenue for eco-friendly pest control through phytoscreening.
