The use of efficient mosquito sampling methods in vector surveillance programs is crucial to inform control actions and prevent outbreaks. amongst existing trapping methods, the BG sentinel trap is widely used for collecting mosquitoes from the subgenus Stegomyia. However, studies state that the BG-sentinel trap underestimates the relative abundance of mosquito vectors. In this study, we used mice to enhance the effectiveness of the BG-sentinel trap to collect Aedes aegypti (Linnaeus) and follow the species’ daily abundance under local conditions. The Latin square method was used to compare different combinations in three different seasons. Of the 35,107 mosquitoes collected, Ae. aegypti (53.82%) and Culex quinquefasciatus (46.07%) were dominant. The combination of BG-Lure + 3 mice captured more Ae. aegypti individuals (apparent density per trap/day (ADT = 187.65 ± 133.53; p < 0.001) followed by the 3 mice-baited BG-sentinel trap (ADT = 163.47 ± 117.32), the BG-sentinel trap without attractant (ADT = 74.15 ± 117.07) and the BG-sentinel trap + BG-Lure (ADT = 47.1 ± 115.91). Aedes aegypti showed two peaks of activity in the day, one following the sunrise and one before the sunset, influenced by temperature and relative humidity. Our study suggests the use of mice to enhance the efficiency of the BG-Sentinel trap to catch Ae. aegypti. However, its application in large scale entomological monitoring programs should be difficult because of ethical and operational constraints.

在媒介监测计划中使用有效的蚊子采样方法对于告知控制行动和预防爆发至关重要。在现有的诱捕方法中，BG 哨兵诱捕器广泛用于收集来自Stegomyia亚属的蚊子。然而，研究表明 BG 哨兵陷阱低估了蚊子载体的相对丰度。在这项研究中，我们使用小鼠来提高 BG 哨兵陷阱的有效性，以收集埃及伊蚊(Linnaeus)，并在当地条件下跟踪该物种的每日丰度。拉丁方法用于比较三个不同季节的不同组合。在收集的 35,107 只蚊子中，Ae。aegypti (53.82%) 和Culex quinquefasciatus(46.07%) 占主导地位。BG-Lure + 3 只小鼠的组合捕获了更多的Ae。aegypti个体（每个陷阱/天的表观密度（ADT = 187.65 ± 133.53；p < 0.001），然后是 3 只老鼠诱饵的 BG 哨兵陷阱（ADT = 163.47 ± 117.32），没有引诱剂的 BG 哨兵陷阱（ADT = 7） ± 117.07) 和 BG-sentinel trap + BG-Lure (ADT = 47.1 ± 115.91). 埃及伊蚊在白天表现出两个活动高峰，一个在日出之后，一个在日落之前，受温度和相对湿度的影响。我们的研究表明，使用小鼠可以提高 BG-Sentinel 陷阱捕捉埃及伊蚊的效率. 然而，由于伦理和操作限制，它在大规模昆虫学监测计划中的应用应该很困难。
