A study of diurnal and nocturnal distribution of flies was conducted in Putrajaya. Six different ecological habitats were selected, namely: botanical garden, lake-area, administration building, wetland, jungle fringes and housing areas. Two different type of traps, cylinderical and rectangular in shape were used in the study. Baits used in these traps were yeast, sugar, salted fish, shrimp paste and fresh liver. Traps were placed at the sites throughout the diurnal and nocturnal periods. The time for sunrise and sunset was determined using a Geographical Positioning System gadget (GARMIN) at the sites. Both type of traps were equally effective in trapping flies. There was no significant difference between both types of traps in their ability to trap flies (p > 0.05). A total of 1,534 flies were collected and identified from both types of trap using the multiple baits and habitats. The collection consisted of 23 species of flies classified under 6 families. The highest number of flies were caught from the lake-area followed by botanical garden, administration building, housing areas, wetland and jungle fringes. The most dominant species was Chrysomya megacephala, followed by species of Sarcophagidae and Musca domestica. Diurnal period had more numbers of flies (81.55%) compared to the nocturnal periods (18.45%). Some species of flies were strictly diurnal, some exibited both diurnal and nocturnal activities while only one species was strictly nocturnal.
在布城开展了一项关于苍蝇昼夜分布的研究。选取了六个不同的生态栖息地，即：植物园、湖区、行政大楼、湿地、丛林边缘和住宅区。研究中使用了两种不同类型的诱捕器，分别为圆柱形和长方形。这些诱捕器使用的诱饵有酵母、糖、咸鱼、虾酱和新鲜肝脏。诱捕器在昼夜期间均放置在这些地点。使用地理定位系统设备（佳明）在这些地点确定日出和日落时间。两种类型的诱捕器在捕获苍蝇方面同样有效。两种诱捕器在捕获苍蝇的能力上没有显著差异（p>0.05）。使用多种诱饵和栖息地，从两种诱捕器中共收集并鉴定出1534只苍蝇。此次收集的苍蝇包括6个科的23个种类。捕获苍蝇数量最多的是湖区，其次是植物园、行政大楼、住宅区、湿地和丛林边缘。最主要的种类是大头金蝇，其次是麻蝇科种类和家蝇。与夜间（18.45%）相比，白天捕获的苍蝇数量更多（81.55%）。有些苍蝇种类严格为昼出性，有些表现出昼夜活动，而只有一种是严格的夜出性。
