Gravid traps are useful tools for monitoring vector-borne pathogens in mosquitoes, particularly for those pathogens transmitted by Culex quinquefasciatus Say. One of the primary challenges in the use of gravid traps is the necessity of the inclusion of an oviposition attractant, usually an infusion of organic material, which changes in attractiveness over time. However, a standardized lure, using nonanal and trimethylamine (N + TMA), has been developed and is commercially available. The N + TMA lure was tested against grass infusion and tap water in Tanzania, where Cx. quinquefasciatus is a vector of lymphatic filariasis. Traps baited with grass infusion collected significantly more mosquitoes than N + TMA-baited traps, which collected significantly more than traps baited with tap water. The advantages and disadvantages of the standardized lure are discussed.
集卵器是监测蚊子传播的病原体的有用工具，特别是对于那些由库蚊传播的病原体。在使用集卵器时，主要的挑战之一是需要包含一种产卵引诱剂，通常是有机物质的浸液，这种引诱剂的吸引力会随着时间的推移而变化。然而，已经开发出一种使用壬醛和三甲胺（N + TMA）的标准化诱饵，并可在商业上获得。在坦桑尼亚，对 N + TMA 诱饵进行了测试，那里的库蚊是淋巴丝虫病的传播媒介。用草浸液诱饵的诱捕器收集的蚊子明显多于用 N + TMA 诱饵的诱捕器，而用 N + TMA 诱饵的诱捕器收集的蚊子明显多于用自来水诱饵的诱捕器。讨论了标准化诱饵的优缺点。
