House flies (Musca domestica L.) are common synanthropic pests associated with confined animal operations, including dairy farms. House flies can cause substantial nuisance and may transmit human and animal pathogens. Surprisingly little is known about the daily flight activity of house flies. This study examined diurnal house fly flight activity on two southern California dairies using clear sticky traps to capture flies over hourly intervals. Flight activity for both males and females combined started near dawn and generally increased to a single broad activity peak during mid to late morning. Male flight activity peaked earlier than female flight activity and this separation in peak activity widened as mean daytime temperature increased. Flight activity for both sexes increased rapidly during early morning in response to the combined effects of increasing light intensity and temperature, with decreasing flight activity late in the day as temperature decreased. During midday, flight activity was slightly negatively associated with light intensity and temperature. Collection period (time of day) was a useful predictor of house fly activity on southern California dairies and the diurnal pattern of flight activity should be considered when developing house fly monitoring and control programs.

家蝇（家蝇）的日间飞行活动受性别，一天中的时间和环境条件的影响。

家蝇（家蝇）L.）是与密闭动物生产有关的常见的合生害虫，包括奶牛场。家蝇会造成严重的滋扰，并可能传播人和动物的病原体。令人惊讶的是，人们对家蝇的日常飞行活动知之甚少。这项研究检查了加利福尼亚南部两个奶牛场的日间果蝇飞行活动，使用透明的粘性诱捕器每小时捕获一次苍蝇。男性和女性的飞行活动加在一起在黎明之前开始，并且通常在中午至傍晚增加到单个活动高峰。男性飞行活动的峰值比女性飞行活动的峰值更早，并且随着白天平均温度的升高，峰值活动中的这种分离扩大。响应于光强度和温度增加的综合作用，清晨两性的飞行活动迅速增加，随着温度的降低，当天晚些时候的飞行活动减少。在午间，飞行活动与光强度和温度略有负相关。收集时间（一天中的时间）是南加州奶牛场蝇活动的有用预测指标，在制定蝇蝇监测和控制程序时应考虑飞行活动的昼夜模式。
