在喀麦隆的热带雨林地区，人们受到黑蝇（Simuplusspp.）和蚊子（按蚊属）。已推广使用驱虫蚊帐，以保护弱势群体免受蚊虫叮咬，而室内滞留喷洒历来是主要的干预措施。在一个疟疾流行地区，一项试点研究审查了适用于整个村庄的不同蚊虫控制干预措施，以评估其对病媒、疟疾发病率和社区生活质量的影响。这些村庄附近的Sanaga河被用杀虫剂处理，以杀死黑蝇幼虫。对六个村庄的医疗调查表明，20%的人口患有疟疾，50%的人感染盘尾丝虫病，5%的人感染Loa loo。与其他处理方法相比，使用ICON CS（三氟氯氰菊酯胶囊悬浮剂）的室内滞留喷洒+驱虫蚊帐或改进的房屋筛查结合室外喷雾减少了从出口诱捕器收集的蚊子数量。在未处理村庄的出口诱捕器中采样的蚊子中检测到的子孢子比处理村庄中的子孢子多。治疗后几个月的疟疾发病率与治疗前水平没有显著差异。在施用杀幼虫剂后数周内，黑蝇成虫数量减少，但在停止治疗后恢复。(C)2009年皇家热带医学和卫生学会。由爱思唯尔有限公司出版。保留所有权利。
In the tropical rainforest area of Cameroon, people are affected by blackflies (Simulium spp.) and mosquitoes (Anopheles spp). Use of insecticide-treated bed nets (ITNs) has been promoted to protect vulnerable groups from mosquito bites, whereas historically indoor residual spraying (IRS) was the primary intervention. In a malaria-endemic area, a pilot study examined different mosquito control interventions applied to entire villages to assess their impact on vectors, malaria incidence and the quality of life of the communities. The Sanaga River near these villages was treated with insecticide to kill blackfly larvae. A medical survey of the six villages had shown that 20% of the population suffered from malaria, while 50% were infected with onchocerciasis and 5% with Loa loo. IRS+ITN using ICON CS (lambda-cyhalothrin capsule suspension formulation) or improved screening of houses combined with outdoor misting reduced the numbers of mosquitoes collected from exit traps compared to the other treatments. More sporozoites were detected in mosquitoes sampled in exit traps in the untreated village than in the treated villages. Malaria incidence several months after treatments was not significantly different from pre-treatment levels. Blackfly adult populations were reduced for several weeks following larvicide application but recovered when treatment was halted. (C) 2009 Royal Society of Tropical Medicine and Hygiene.
