在坦桑尼亚的达累斯萨拉姆调查了一种廉价而简单的家庭保护方法对致倦库蚊和其他蚊子（双翅目：库蚊科）的有效性。煤油燃烧灯（korobois）进行了修改，以加热和蒸发四氟菊酯，挥发性拟除虫菊酯类杀虫剂。当将四氟苯菊酯添加到灯的燃料中时，除非使用非常高浓度的杀虫剂，否则对叮咬的保护很差。一种改进的灯（=汽化koroboi）被设计来克服这个问题，通过将杀虫剂与植物油混合，并将其加热到120 degreesC，放在火焰上方的锡中。在植物油中加入0.1%的四氟苯菊酯可使叮咬减少50-75%，保护程度与燃烧含有合成拟除虫菊酯（0.25%右旋丙烯菊酯）的蚊香相似，且保护效果明显优于当地购买的蚊香（品牌为“白色鹤”，可能含有滴滴涕）。在植物油中使用较高浓度的四氟菊酯（0.5%）可获得更大的保护（始终> 90%）。这种改进的灯简单、便宜，并采用当地现有的技术。随着进一步的发展，并充分考虑到蒸发材料的吸入毒性，它可能提供一个更具成本效益的替代蚊香作为个人保护手段，并在睡前的前一部分蚊帐的有用补充。
The effectiveness of a cheap and easy method of household protection against Culex quinquefasciatus Say and other mosquitoes (Diptera: Culicidae) was investigated in Dar es Salaam, Tanzania. Kerosene-burning lamps (korobois) were modified to heat and vaporize transfluthrin, a volatile pyrethroid insecticide. When transfluthrin was added to fuel of the lamp, protection against biting was poor unless a very high concentration of insecticide was used. A modified lamp (= vaporizing koroboi) was designed to overcome this problem by mixing the insecticide with vegetable oil and heating it to 120 degreesC in a tin held just above the flame. The concentration of 0.1% transfluthrin in vegetable oil gave 50-75% reduction in biting, a similar degree of protection to that obtained from burning a mosquito coil containing a synthetic pyrethroid (0.25% d-allethrin) and significantly better protection than a locally bought coil (brand 'White Crane', probably containing DDT). Greater protection (consistently > 90%) was achieved with a higher concentration of transfluthrin (0.5%) in the vegetable oil. This modified lamp is simple, cheap and employs locally available technology. With further development, and due regard to inhalation toxicity of the vaporized materials, it may offer a more cost-effective alternative to a mosquito coil as a means of personal protection, and a useful complement to a net for the early part of the evening before bedtime.
