Abstract：
BACKGROUND: There are many different traps available for studying fly populations. The aim of this study was to find the most suitable trap to collect synanthropic fly populations to assess the impact of increased latrine coverage in the state of Odisha, India.
METHODS: Different baits were assessed for use in sticky pot traps (60% sucrose solution, 60 g dry sucrose, half a tomato and an non-baited control), followed by different colours of trap (blue versus yellow) and finally different types of trap (baited sticky pot trap versus sticky card traps). The experiments were undertaken in a semi-urban slum area of Bhubaneswar, the capital of Odisha. The first experiment was conducted in 16 households over 30 nights while experiments 2 and 3 were conducted in 5 households over 30 nights.
RESULTS: The traps predominantly caught adult Musca domestica and M. sorbens (78.4, 62.6, 83.8% combined total in experiments 1-3 respectively). Non-baited traps did not catch more flies (median 7.0, interquartile range, IQR: 0.0-24.0) compared with baited traps (sucrose solution: 6.5, 1.0-27.0; dry sucrose: 5.0, 0.5-14.5; tomato: 5.0, 1.5-17.5). However, there were significantly more flies collected on blue sticky pot traps, which caught nearly three times as many flies as yellow sticky pot traps (Incidence Rate Ratio, IRR = 2.91; 95% CI: 1.77-4.79); P < 0.001). Sticky card traps (27, 8-58) collected significantly more flies than the non-baited sticky pot traps (10, 1.5-30.5).
CONCLUSIONS: Blue sticky card traps can be recommended for the capture of synanthropic fly species as they are non-intrusive to residents, easy to use, readily allow for species identification, and collect sufficient quantities of flies over 12 hours for use in monitoring and control programmes.

摘要：
背景：有许多不同的陷阱可用于研究苍蝇种群。这项研究的目的是找到最合适的陷阱来收集同人蝇种群，以评估奥里萨邦厕所覆盖率增加的影响，印度。
方法：评估了不同的诱饵在粘罐诱捕器中的使用情况（60％蔗糖溶液，60克干蔗糖，半个番茄和一个非诱饵对照)，其次是不同颜色的陷阱（蓝色与黄色），最后是不同类型的陷阱（诱饵粘罐陷阱与粘卡陷阱）。实验是在布巴内斯瓦尔的半城市贫民窟地区进行的，首都奥里萨邦。第一个实验是在30个晚上的16个家庭中进行的，而实验2和3是在30个晚上的5个家庭中进行的。
结果：诱捕器主要捕获成年家蝇和M.sorbens（在实验1-3中分别为78.4、62.6、83.8％）。非诱饵陷阱没有捕获更多的苍蝇（中位数7.0，四分位数间距，IQR：0.0-24.0）与诱饵诱捕器（蔗糖溶液：6.5，1.0-27.0；干蔗糖：5.0，0.5-14.5；番茄：5.0，1.5-17.5）相比。然而,在蓝色粘锅诱捕器上收集的苍蝇明显更多，它捕获的苍蝇几乎是黄色粘罐陷阱的三倍(发病率比，IRR=2.91；95%CI：1.77-4.79）；P<0.001）。粘卡诱捕器（27，8-58）收集的苍蝇比非诱饵粘罐诱捕器（10，1.5-30.5）明显更多。
结论：蓝色粘卡陷阱可以推荐用于捕获同人蝇物种，因为它们对居民没有侵入性，易于使用,容易允许物种识别，并在12小时内收集足够数量的苍蝇，用于监测和控制程序。
