Abstract: Objective To determine the responses of housefly adults to different foods. Methods In laboratory Y-shape olfactometer was used under dynamic airflow in this study. Results Housefly adults at different day-ages were significantly attracted to the brown sugar, the milk powder and the fish powder. The average quantities of housefly adults at different day-ages attracted by the brown sugar, the milk powder and the fish powder were (5.4-7.4), (5.2-7.2) and (4.4-6.8) respectively, which were respectively (4.5-18.0), (6.5-12.0) and (2.3-11.3) times of that of controls. The rice flour and the egg roll had greater attraction to the houseflies of more than 2 or 3 day-ages but the response to peptone is related to day-ages of adult. Conclusion Housefly adults prefer to food with abundant sugar and proteins. Brown sugar, milk powder and fish powder would have great applied potential as the key components of bait for the control of houseflies.
