在全球范围内，越来越多地推广清洁烹饪燃料，以减少家庭空气污染。然而，人们担心生物质燃料产生的烟雾减少可能会给蚊子带来更有利的条件，并可能增加媒介传播疾病的风险。我们在卢旺达的六个实验小屋中调查了三种烹饪燃料类型（木材、木炭和液化石油气 (LPG)）中按蚊的入户、寻找寄主、出户和死亡率。每晚在每个小屋外的入口隔间释放 50 只实验室饲养的冈比亚按蚊，并在小屋阳台上燃烧燃料 1 小时。收集者在烹饪期间和烹饪后 2 小时内进行人类登陆捕捉，并在当晚剩余时间使用 CDC 光陷阱来测量宿主寻找情况。使用广义线性混合模型评估每个结果的差异，并对小屋、收集器和白天进行随机效应。与使用木材和木炭相比，使用液化石油气烹饪与入户和寻找寄宿家庭的人数大幅增加有关。不同燃料的家庭退出没有显着差异，与木材相比，燃烧液化石油气的小屋的死亡率较低。尽管这些结果不能直接推广到现场条件，但它们表明与传统生物质燃料相比，采用清洁燃料有可能增加按蚊的接触机会。需要进行更多的昆虫学和流行病学研究来调查与采用清洁燃料相关的病媒接触变化，并评估是否应与清洁烹饪燃料同时推广加强病媒控制干预措施。
Globally, cleaner cooking fuels are increasingly promoted to reduce household air pollution. However, there is concern that reductions in smoke from biomass fuels could lead to more favorable conditions for mosquitoes and potentially increase vectorborne disease risk. We investigated household entry, host-seeking, household exit, and mortality among Anopheles mosquitoes across three cooking fuel types: wood, charcoal, and liquid petroleum gas (LPG) in six experimental huts in Rwanda. Fifty laboratory-reared Anopheles gambiae mosquitoes were released each night in entry compartments outside each hut, and fuels were burned for 1 hour in the hut verandas. Collectors conducted human landing catch during cooking and for 2 hours afterward, and CDC light traps were used for the rest of the night to measure host-seeking. Differences in each outcome were assessed using generalized linear mixed models with random effects for hut, collector, and day. Cooking with LPG compared with wood and charcoal was associated with substantial increases in household entry and host-seeking. Household exit was not significantly different across fuels, and mortality was lower in LPG-burning huts compared with wood. Although these results are not directly generalizable to field conditions, they indicate a potential for clean fuel adoption to increase exposure to Anopheles mosquitoes compared with traditional biomass fuels. Additional entomological and epidemiological studies are needed to investigate changes in disease vector exposure associated with clean fuel adoption, and evaluate whether enhanced vector control interventions should be promoted in tandem with cleaner cooking fuels.
