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.

摘要： 目的 测定家蝇成虫对不同食物气味的反应。方法 在实验室内利用"Y"形嗅觉仪在动态的气流中进行测定。结果 不同日龄的家蝇成虫对红糖、奶粉、鱼粉均有显著的趋向反应,以红糖、奶粉、鱼粉作为引诱物引诱到不同日龄家蝇的成虫数分别为(5.4～7.4)只、(5.2～7.2)只和(4.4～6.8)只,分别是对照组诱蝇只数的(4.5～18.0)倍、(6.5～12.0)倍和(2.3～11.3)倍。家蝇成虫对蛋卷、米粉的趋向反应一般,对蛋白胨的趋向反应则与日龄有关。结论 家蝇非常喜爱含糖类、蛋白质的物质,红糖、奶粉、鱼粉在家蝇防治中作为引诱物,具有一定的应用潜力。
