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.
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。
