In this study, we compared the efficacy of the newly available BG-Sentinel with an established "gold standard,", the CDC Backpack Aspirator, and a CO2-baited EVS trap for the collection of Aedes aegypti (L.) in Cairns, Australia. BG-Sentinels collected significantly more (P = 0.017) female Ae. aegypti (mean per collection, 1.92 +/- 0.39) than both the CDC Backpack Aspirator (1.00 +/- 0.35) and the EVS trap (0.71 +/- 0.27). Male-only and combined male-female Ae. aegypti collections for th BG-Sentinel and the CDC Backpack Aspirator were also greater than EVS trap collections. The CDC Backpack Aspirator and the BG-Sentinel captured proportionally fewer females compared with the EVS trap. The BG-Sentinel was the most Ae. aegypti specific collection method. The CDC Backpack Aspirator collected proportionally more bloodfed Ae. aegypti than the other methods, which collected a greater proportion of nullipars. The data presented here will aid researchers in deciding what Ae. aegypti sampling device best suits their needs. BG-Sentinels and CDC Backpack Aspirators should be considered as alternatives to human-bait collections for Ae. aegypti sampling.
在本研究中，我们比较了新推出的BG-Sentinel诱蚊器与既定的“金标准”——美国疾病控制与预防中心（CDC）背负式吸气捕蚊器，以及一种以二氧化碳为诱饵的EVS诱蚊器在澳大利亚凯恩斯收集埃及伊蚊的效果。BG-Sentinel诱蚊器收集到的埃及伊蚊雌蚊显著更多（P = 0.017）（每次收集的平均数为1.92±0.39只），多于CDC背负式吸气捕蚊器（1.00±0.35只）和EVS诱蚊器（0.71±0.27只）。BG-Sentinel诱蚊器和CDC背负式吸气捕蚊器收集到的仅为雄蚊以及雌雄混合的埃及伊蚊数量也多于EVS诱蚊器。与EVS诱蚊器相比，CDC背负式吸气捕蚊器和BG-Sentinel诱蚊器捕获的雌蚊比例相对较少。BG-Sentinel诱蚊器是最具埃及伊蚊针对性的收集方法。CDC背负式吸气捕蚊器收集到的吸血埃及伊蚊比例相对高于其他方法，其他方法收集到的未产卵雌蚊比例更高。此处呈现的数据将有助于研究人员决定哪种埃及伊蚊采样设备最符合他们的需求。对于埃及伊蚊采样，应考虑将BG-Sentinel诱蚊器和CDC背负式吸气捕蚊器作为人饵收集方法的替代方案。
