在布基纳法索瓦加杜古附近的一个村庄，在两个雨季期间，对微型CDC光陷阱捕捉西非疟疾病媒的效率进行了评估。在室内和室外都使用了诱捕器，使用人饵，由无杀虫剂的蚊帐和不同的光源保护。在室内，白炽灯泡发出的光增加了冈比亚按蚊的捕获量。主要是A。arabiensis Patton和A.冈比亚公司Giles）和A. funestus Giles c. 2.5时间相比，陷阱的灯泡被删除。相反，当紫外线“蓝光”荧光灯管与白炽灯泡相比时，差异并不显著。用蚊帐保护诱饵增加了捕获量。3次为A。冈比亚公司和c. 3.5时间为A，funestus。双层蚊帐的原型模型提供了中等产量。在户外，在没有照明的陷阱中加入白炽灯泡并没有显著增加捕获的媒介数量，但是在没有保护的人类诱饵中加入蚊帐，c。1.5 - 4倍。因此，CDC灯诱捕器悬挂在靠近睡在蚊帐下的人的位置，并配有白炽灯泡，被认为是在捕获的病媒数量方面最实用和最有效的，因此将其室内效率与单个收集器上的人着陆捕获量进行了比较，估计为1.08倍，与密度无关。户外光诱捕获量与叮咬收集量没有显着相关性（例如冈比亚A，gambiae s.l.），或密度依赖于它们的效率（如对于A. funestus）;因此，不认为它们是估计该地区疟疾病媒户外叮咬密度的可靠手段。两组间A的经产率无差异。冈比亚公司从CDC光陷阱和人类着陆收集中获得的样本。
The efficiency of miniature CDC light-traps in catching West African malaria vectors was evaluated during two rainy seasons in a village near Ouagadougou, Burkina Faso. Traps were employed both indoors and outdoors using human baits protected by an insecticide-free mosquito-net and different sources of light. Indoors, light from incandescent bulbs increased the catch of Anopheles gambiae s.l. (mainly A. arabiensis Patton and the Mopti chromosomal form of A. gambiae s.s. Giles) and A. funestus Giles c. 2.5 times as compared to traps whose light bulb was removed. Conversely, the difference was not significant when a UV 'Blacklight-blue' fluorescent tube was compared to the incandescent bulb. Protecting the bait with a mosquito-net increased the catch c. 3 times for A. gambiae s.l. and c. 3.5 times for A, funestus. A prototype model of double bednet gave intermediate yields. Outdoors, the addition of incandescent bulbs to unlighted traps did not significantly increase the number of vectors caught, but the addition of the mosquito-net to the unprotected human bait did so by c. 1.5-4 times. Thus, the CDC light-trap hung close to a human sleeping under a bednet and fitted with an incandescent bulb, was considered the most practical and efficient in terms of numbers of vectors caught, consequently its indoor efficiency was compared to human landing catches on single collectors and estimated to be 1.08 times and density-independent. Outdoor light-trap catches were either not significantly correlated to biting collections (as for A, gambiae s.l.), or density-dependent in their efficiency (as for A. funestus); thus, they were not considered a reliable means for estimating malaria vector outdoor biting densities in this area. No difference was found in the parous rate of A. gambiae s.l. samples obtained with CDC light-traps and human landing collections.
