Outbreaks of arboviral diseases pose a significant threat to health security in Pacific Island countries and territories. In the absence of vaccines or treatments, effective vector control is critical to reduce risk and respond to outbreaks. This relies on sustainable mosquito surveillance strategies to identify vectors and guide control efforts. This study evaluated the performance and feasibility of three adult mosquito sampling methods-BG-Sentinel II (BGS) traps, BG Gravid Traps (GAT), and sweep netting (SWN)-in six Pacific countries: Cook Islands, Fiji, Kiribati, Samoa, Solomon Islands, and Tonga. Sampling followed a Latin square design across 54 sites in 18 locations. Data were analysed using a generalised linear mixed model and Simpson's Index for diversity. Qualitative interviews with public health staff captured operational experiences. 2815 mosquitoes were collected, with species comprising 61 %. Species composition varied significantly between countries ( < 0.05). BGS traps yielded considerably more mosquitoes than GAT and SWN (p < 0.05). No major species bias was observed across sampling methods. The public health staff interviewed emphasised the value of mentoring, co-design, and resourcing for operational research. Pacific context-specific challenges underscored the need for simple, durable tools for routine use, particularly if to be used in remote settings. This is the first multi-country study conducted in the Pacific to compare sampling methods.
虫媒病毒疾病的爆发对太平洋岛国和领土的卫生安全构成重大威胁。在缺乏疫苗或治疗方法的情况下，有效的病媒控制对于降低风险和应对疫情至关重要。这依赖于可持续的蚊虫监测策略来识别病媒并指导控制工作。本研究评估了三种成蚊采样方法——BG-哨兵II型（BGS）诱捕器、BG孕蚊诱捕器（GAT）和扫网法（SWN）——在六个太平洋国家（库克群岛、斐济、基里巴斯、萨摩亚、所罗门群岛和汤加）的性能和可行性。采样采用拉丁方设计，涵盖18个地点的54个采样点。使用广义线性混合模型和辛普森多样性指数对数据进行分析。对公共卫生工作人员进行的定性访谈记录了实际操作经验。共收集到2815只蚊子，其中[具体物种名称]占61%。各国之间的物种组成差异显著（p<0.05）。BGS诱捕器捕获的蚊子比GAT和SWN多得多（p<0.05）。在各种采样方法中未观察到明显的物种偏差。接受访谈的公共卫生工作人员强调了指导、共同设计和为行动研究提供资源的价值。太平洋地区特有的挑战凸显了对常规使用的简单、耐用工具的需求，特别是如果要在偏远地区使用的话。这是在太平洋地区进行的第一项比较采样方法的多国研究。
