Motivation for the study. Rural health facilities could be potential foci of transmission and scenarios of zoonosis during epidemic outbreaks of dengue and other arbovirosis due to the coexistence of mosquito species that feed on different vertebrates.
Main findings. Aedes aegypti feeds on Homo sapiens sapiens. Culex quinquefasciatus feeds on Homo sapiens sapiens and Canis familiaris. Both coexist in health care areas of the Querecotillo health center.
Implications. Molecular techniques should be integrated into vector control to understand feeding patterns in natural conditions and information on probable reservoirs.
This study aimed to determine the coexistence and food sources of adult mosquitoes (Diptera: Culicidae) in a rural health center in Piura, Peru by using a descriptive cross-sectional design. Entomological techniques were used to capture and identify mosquitoes, and molecular biotechnology techniques were used to identify food sources. A total of 793 specimens of the Culex and Aedes genera were found coexisting, 789 (99.5%) were Culex quinquefasciatus, 607 (76.9%) were males and 182 (23.1%) were females. Likewise, 4 (100%) corresponded to Aedes aegypti females. The food sources of Aedes aegypti were Homo sapiens sapiens, and Homo sapiens sapiens and Canis familiaris were the food sources of Culex quinquefasciatus. This study provides evidence that rural health centers could be acting as foci of arbovirosis, with the risk that people who come for different ailments could contract diseases transmitted by C. quinquefasciatus and A. aegypti.
研究动机。由于存在以不同脊椎动物为食的蚊子物种，农村卫生设施在登革热和其他虫媒病毒病流行爆发期间可能成为传播和人畜共患病发生的潜在焦点。
主要发现。埃及伊蚊以智人为食。库蚊以智人和犬为食。这两种蚊子都存在于 Querecotillo 保健中心的医疗区域。
影响。应将分子技术纳入病媒控制，以了解自然条件下的摄食模式和可能的储存宿主信息。
本研究旨在通过使用描述性横断面设计，确定秘鲁皮乌拉农村卫生中心成年蚊子（双翅目：库蚊科）的共存和食物来源。使用昆虫学技术捕获和鉴定蚊子，并使用分子生物技术鉴定食物来源。共发现 793 只库蚊属和伊蚊属蚊子共存，其中 789 只（99.5%）为库蚊，607 只为雄性，182 只为雌性。同样，有 4 只（100%）为埃及伊蚊雌蚊。埃及伊蚊的食物来源为智人，库蚊的食物来源为智人和犬。本研究提供了证据表明，农村卫生中心可能成为虫媒病毒病的焦点，前来治疗不同疾病的人可能会感染库蚊和埃及伊蚊传播的疾病。
