Biogents Sentinel (BGS) 诱捕器已迅速成为成年埃及伊蚊监测的标准。一些调查人员发现，大量露水或雨水进入捕集器入口很容易损坏捕集器收藏品。此外，进入疏水阀的水可能会暂时停止风扇，从而降低疏水阀的收集潜力。我们评估了防雨罩的有效性，该防雨罩旨在最大程度地减少佛罗里达州杰克逊维尔住宅后院 BGS 2.0 诱蚊器对蚊虫诱捕器集合的损害。防雨罩由白色玻璃纤维 51 厘米(2) 片组成，位于陷阱进气口上方 19、29 和 39 厘米处。一个 BGS 陷阱没有防雨罩，用作比较的控制标准。所有陷阱均使用 BG-Lure 作为诱饵。一般来说，与没有遮盖的诱捕器相比，带有防雨罩的诱捕器会导致更多的蚊子数量。防雨罩位于 29 厘米处的诱捕器的总体蚊子丰度较高，但与其他覆盖高度相比，这种差异没有显着差异。与间隔 19 厘米且无覆盖的陷阱相比，间隔 29 或 39 厘米的覆盖物捕获的致倦库蚊明显更多。防雨盖位于 29 厘米处的 BGS 诱捕器的物种多样性最大，其次是 39 厘米、19 厘米和无盖；然而，无论有没有盖子，陷阱之间的多样性差异并不显着。
Biogents Sentinel (BGS) traps have rapidly become a standard for adult Aedes aegypti surveillance. Several investigators have found that trap collections can be damaged easily by heavy dew or rain entering the trap intake port. In addition, water entering the trap may temporarily stop the fan, thus reducing the collection potential of the trap. We evaluated the effectiveness of a rain cover designed to minimize damage to mosquito trap collections from BGS 2.0 traps in a residential backyard in Jacksonville, FL. Rain covers consisted of white fiberglass 51-cm(2) sheets positioned 19, 29, and 39 cm above the air intake of the traps. One BGS trap did not have a rain cover and was used as a control standard for comparison. All traps were baited with the BG-Lure. Generally, traps with rain covers resulted in higher mosquito counts when compared with collections from uncovered traps. Overall mosquito abundance was greater from traps with the rain cover positioned at 29 cm, but this difference was not significantly different when compared with the other cover heights. Covers spaced 29 or 39 cm collected significantly more Culex quinquefasciatus compared with traps at 19 cm and no cover. Species diversity was greatest for BGS traps with the rain cover positioned at 29 cm followed by 39 cm, 19 cm, and no cover; however, differences in diversity among the traps, with or without covers, were not significant.
