The existence of a female sex attractant or pheromone In Bucculatrix thurberiella Busck was demonstrated using "Y" and "swastika" type olfactometers. The males performed the typical mating "dance" when exposed to the virgin females in the olfactometer.

The attractancy of 1, 5, 10, 20 and 50 females, as pheromone source or excitant, did not significantly vary in either type of apparatus. Attraction of 100% was not attained in the 2 olfactometers.

The peak mating activities or presumably pheromone release occurred between 5 and 8 PM, as recorded by a clock-operated turntable. A smaller peak activity occurred between 1 and 2 AM, and thereafter the number of moths attracted decreased until no moths were caught at 12 M.
