The role of ammonia in the attraction of females of the Mediterranean fruit fly to protein hydrolysate baits

Attraction of female Mediterranean fruitfly (medfly) to ammonia and to protein baits was studied with an olfactometer. Ammonia bait (1 cc/trap) proved to be an effective lure. The maximum number of females was caught in traps loaded with 0.01 M ammonia solution with a release rate of 5.28 μg/cc/h.
