We report the development of a new mosquito aspirator with the same aspiration capacity (airflow) of the CDC Backpack Aspirator (CDC-BP), but smaller and lighter (0.8 kg without battery), less expensive (US$45-70), easier to build, and compatible with the use of telescoping extension poles to access hard-to-reach locations. The performance of this new aspirator, named "Prokopack," was compared with the CDC-BP in laboratory settings as well as in paired collections in combined sewer overflow (CSO) tunnels in Atlanta, GA, and indoor mosquito collections in Iquitos, Peru. The difference in suction power between both aspirators (average, 0.29-0.43 m/s) was negligible. However, 2.3 times more mosquitoes were collected using the Prokopack in the upper wall (>1.5 m) and ceilings of CSO tunnels than with the CDC-BP in lower walls. Indoor collection in Iquitos yielded significantly more total mosquito numbers [including Culex pipiens complex, Culex (melanoconion) sp., and Mansonia sp.] and Aedes aegypti (L.) in the Prokopack than in the CDC-BP. Our results demonstrate the effectiveness of the Prokopack to collect different mosquito species in different epidemiological settings.
我们开发了一种新型的蚊虫抽吸器,其吸气量(气流)与 CDC 背包抽吸器(CDC-BP)相同,但体积更小、重量更轻(不含电池时为 0.8 千克)、价格更低廉(45-70 美元)、更易于制造,并且可与伸缩延长杆配合使用,以进入难以到达的地方。这种名为“Prokopack”的新型抽吸器的性能在实验室环境以及在佐治亚州亚特兰大的合流污水溢流(CSO)隧道中的配对收集以及在秘鲁伊基托斯的室内蚊虫收集方面与 CDC-BP 进行了比较。两种抽吸器之间的吸力差异(平均值为 0.29-0.43 m/s)可以忽略不计。然而,与 CDC-BP 相比,Prokopack 在 CSO 隧道的上部墙壁(>1.5 m)和天花板上收集的蚊子数量多 2.3 倍。在伊基托斯的室内收集,Prokopack 收集到的蚊子总数(包括库蚊复合体、库蚊(melanoconion)种和曼蚊属)和埃及伊蚊(L.)明显多于 CDC-BP。我们的结果表明,Prokopack 可有效在不同的流行病学环境中收集不同的蚊虫种类。
