Sexual performance of male and female Queensland fruit flies (Q-flies) is greatly enhanced by protein feeding, most likely due to increased maturation rates. We here present new findings demonstrating that olfactory response of these flies to the attractant 'cue-lure' is also enhanced by protein feeding. We tracked development of attraction to cue-lure by virgin Q-flies given various periods of access to dietary protein (continuous, 48 hrs, 24 hrs, no access). Both males and females showed increased attraction as they aged and matured. Flies with continuous access to protein were least attracted. Whereas males tended to approach cue-lure traps in the morning, females tended to respond at dusk. This sex difference is consistent with the possibility that cue-lure resembles natural chemicals on which males feed and use as precursors for sex pheromones. The implications of these results for Q-fly reproductive behavior and management will be discussed.
