Current malaria control strategies have cut down the malaria burden in many endemic areas, however the emergence and rapid spread of insecticide and drug resistance undermine the success of these efforts. There is growing concern that malaria eradication will not be achieved without the introduction of novel control tools. One approach that has been developed in the last few years is based on house screening to reduce indoor mosquito vector densities and consequently decrease malaria transmission. Here screening and trapping were combined in one tool to control mosquito populations. The trap does not require an insecticide or even an attractant, yet it effectively collects incoming resistant and susceptible mosquitoes and kills them.
Performance of the funnel entry trap was tested in low and high malaria vector density areas. An overall reduction of 70 to 80% of mosquito density was seen in both. Species and molecular forms of Anopheles gambiae identification indicated no variation in the number of Anopheles arabiensis and the molecular forms of An. gambiae between houses and traps. Mosquitoes collected in the traps and in houses were highly resistant to pyrethroids (0.9 kdr-based mechanism).
There is a global consensus that new intervention tools are needed to cross the last miles in malaria elimination/eradication. The funnel entry trap showed excellent promise in suppressing mosquito densities even in area of high insecticide resistance. It requires no chemicals and is self-operated.
当前的疟疾控制策略已经在许多流行地区降低了疟疾负担，然而杀虫剂和药物耐药性的出现和迅速传播破坏了这些努力的成功。人们越来越担心，如果不引入新的控制工具，疟疾将无法根除。近年来开发的一种方法是基于房屋筛查，以降低室内蚊子媒介密度，从而减少疟疾传播。在这里，筛查和诱捕被结合在一种工具中，以控制蚊子种群。这种诱捕器不需要杀虫剂，甚至不需要引诱剂，但它可以有效地收集进入的抗药性和敏感性蚊子并将其杀死。
在低和高疟疾媒介密度地区测试了漏斗入口诱捕器的性能。在这两个地区，蚊子密度总体降低了 70%到 80%。冈比亚按蚊的种类和分子形式鉴定表明，房屋和诱捕器之间的阿拉伯按蚊数量和冈比亚按蚊的分子形式没有变化。诱捕器和房屋中收集的蚊子对拟除虫菊酯高度耐药（基于 0.9 kdr 的机制）。
全球共识认为，需要新的干预工具来跨越疟疾消除/根除的最后几英里。即使在杀虫剂耐药性高的地区，漏斗入口诱捕器也显示出了很好的抑制蚊子密度的潜力。它不需要化学物质，并且可以自行操作。
