Biconical traps were used to capture continuously Glossina palpalis s.l. in Ivory Coast and G. morsitans centralis in Zambia for 19 and 20 days respectively. Both fly populations declined markedly during the continuous trapping period though populations subjected to intermittent trapping or where the traps were very widely spaced did not do so to the same extent. Fly density was estimated by applying the principles of removal trapping and were compared with other trapping studies. The results demonstrated that biconical traps removed 7% of the female component of the population each day and that this 7% removal value was itself a measure of absolute trapping efficiency; providing a novel means of population estimation. The potential of traps to control tsetse and thus break trypanosome transmission cycles or reduce 'challenge' on a self-help basis at the village level is discussed.
在科特迪瓦，使用双锥形诱捕器连续19天捕获拟舌蝇复合种；在赞比亚，使用双锥形诱捕器连续20天捕获中南非采采蝇。在连续诱捕期间，两个蝇种群数量均显著下降，不过，那些经历间歇性诱捕或诱捕器间隔非常大的种群，数量下降幅度没那么大。通过应用去除式诱捕原理估计蝇密度，并与其他诱捕研究进行比较。结果表明，双锥形诱捕器每天能去除种群中7%的雌性个体，而这个7%的去除值本身就是绝对诱捕效率的一种衡量方式；这提供了一种新的种群估计方法。文中还讨论了诱捕器在控制采采蝇从而打破锥虫传播周期，或在村庄层面自助降低“感染风险”方面的潜力。
