Malaria vector surveillance provides important data to inform the effective planning of vector control interventions at a local level. The aim of this study was to determine the species diversity and abundance, biting activity, and infectivity of mosquitoes from a rural village in southern Mozambique. Human landing catches were performed monthly between December 2020 and August 2021. All collected were identified to the species level and tested for the presence of malaria parasites. Eight species were identified among the 1802 collected anophelines. sensu lato (s.l.) were the most abundant (51.9%) and were represented by and . s.l. represented 4.5%. The biting activity of was more pronounced early in the evening and outdoors, whereas that of sensu stricto (s.s.) was more intense late in the night, with no significant differences in location. One and one , both collected outdoors, were infected with . The overall entomologic inoculation rate was estimated at 0.015 infective bites per person per night. The significant outdoor and early evening biting activity of and . found in this village may negatively impact the effectiveness of current vector control interventions. Additional vector control tools that can target these mosquitoes are needed.
疟疾媒介监测为在当地有效规划媒介控制干预措施提供了重要数据。本研究旨在确定莫桑比克南部一个农村村庄的蚊子的物种多样性和丰度、叮咬活动和感染性。2020 年 12 月至 2021 年 8 月期间,每月进行一次人体诱捕。所有收集到的都被鉴定到种的水平,并检测是否存在疟原虫。在收集到的 1802 只按蚊中,共鉴定出 8 个种。s.l. 最为丰富(51.9%),由 和 代表。s.l. 占 4.5%。 的叮咬活动在傍晚和户外更为明显,而 s.s. 的叮咬活动则在深夜更为强烈,但在地点上没有显著差异。一只 和一只 ,均在户外收集,感染了 。总的昆虫接种率估计为每人每晚 0.015 次感染性叮咬。在这个村庄发现的 和 显著的户外和傍晚活动可能会降低当前媒介控制干预措施的效果。需要额外的能够针对这些蚊子的媒介控制工具。
