Five blue and black cloth traps designed for tsetse were tested for their ability to catch Stomoxys spp. in Kenya. Significantly greatest catches were obtained with Vavoua traps, which then were used to compare odor baits at Nairobi Park. Acetone, lactic acid, and animal urine (cow, buffalo, waterbuck, camel) or dung (rhinoceros, elephant, hippopotamus) did not increase catches. However, 1-octen-3-ol dispensed at 0.2-2.0 mg/h increased catches up to 3.7-fold. Vavoua traps were highly specific for Stomoxyinae, with 80% of the catch consisting of 11 different taxa of Stomoxys as well as genera such as Prostomoxys, Haematobosca, Stygeromyia, and Rhinomusca. During periods of peak seasonal abundance, up to 3,000 Stomoxys per day were collected in an octenol-baited Vavoua trap. These high catches suggest that Vavoua traps may be of practical use for fly control in isolated settings at a relatively low cost.
在肯尼亚，对五种设计用于捕捉采采蝇的蓝黑布诱捕器进行了测试，以评估它们捕捉厩螫蝇属昆虫的能力。使用瓦武阿诱捕器捕获的数量显著最多，随后用其在内罗毕公园比较气味诱饵。丙酮、乳酸以及动物尿液（牛、水牛、水羚、骆驼）或粪便（犀牛、大象、河马）均未增加捕获量。然而，以0.2 - 2.0毫克/小时的量散发1 - 辛烯 - 3 - 醇可使捕获量增加高达3.7倍。瓦武阿诱捕器对厩螫蝇亚科具有高度特异性，捕获物的80%由11种不同的厩螫蝇类群以及原厩螫蝇属、血蝇属、斯氏蝇属和犀蝇属等属的昆虫组成。在季节性数量高峰期，一个用辛烯醇作诱饵的瓦武阿诱捕器每天可收集多达3000只厩螫蝇。这些高捕获量表明，瓦武阿诱捕器可能以相对较低的成本在孤立环境中实际用于控制苍蝇。
