进行实验以改进NG 2B舌蝇诱捕器（Brightwell等人，1987年），用丙酮和牛尿作诱饵，供农村社区用于控制G.pallidipes Austen和G.longipennis Corti。 修改包括降低丙酮的剂量率，新的笼设计和提高陷阱约15-20厘米。 不同的陷阱锥材料的研究表明，透光度的网，而不是它的颜色，是影响G. pallidipes捕获的关键因素。 在陷阱的一侧增加一米的蓝色布，这两个物种的雌性捕获量增加了约60%。 与天然牛尿相比，用合成酚类诱饵的陷阱产生了相似数量的G.pallidipes和显着更多的G.longipennis。 当还使用辛烯醇时，后一种差异不明显，因此牛尿被保留作为优先于进口酚的气味诱饵之一。 虽然辛烯醇仅使苍白足银鲛的捕获量增加了约30%，但长翅银鲛的捕获量增加了2-4倍，使其成为后者非常有用的引诱剂。 诱捕器/气味诱饵系统的费用估计为每年每单位8.5美元。 本文还讨论了这种舌蝇控制方法的经济性。
Experiments were carried out to improve the NG2B tsetse trap (Brightwell et al., 1987), baited with acetone and cow urine, for use by rural communities to control G.pallidipes Austen and G.longipennis Corti. Modifications included a lower dose rate of acetone, a new cage design and raising the trap about 15-20 cm. Research on different trap cone materials showed that the degree of light transmission of the netting, rather than its colour, was the crucial factor affecting the catch of G.pallidipes. Adding an additional metre of blue cloth to one side of the trap increased catches of females of both species by about 60%. Traps baited with synthetic phenols yielded similar numbers of G.pallidipes and significantly more G.longipennis than those baited with natural cow urine. The latter difference was not apparent when octenol was also used, so cow urine was retained as one of the odour baits in preference to the imported phenols. Although octenol increased catches of G.pallidipes by only about 30%, catches of G.longipennis were increased 2-4-fold, making it a very useful attractant for the latter species. The cost of the trap/odour-bait system was estimated to be US$8.5 per unit per annum. The economics of this method of tsetse control are discussed.
