We compared the efficacy of the Biogents Gravid Aedes Trap (BG-GAT) and Biogents-2 Sentinel (BG2S) trap to assess differences in adult mosquito collection rates between these 2 mosquito surveillance methods in northeastern Florida. Species diversity of trap collections was significantly greater for BG2S than for BG-GAT, with 14 mosquito species collected from the former trap and 4 species from the latter. Aedes aegypti and Culex quinquefasciatus were the 2 predominant species collected in both traps. Overall, BG2S traps collected significantly more mosquitoes (in some instances nearly 5 times) than the BG-GAT, regardless of species. There was no significant difference between the 2 traps with respect to gravid status when total species and number of mosquitoes collected were compared. However, at the species level, 8% of Ae. aegypti were gravid from the BG-GAT collections compared with 1% from the BG2S. The number of gravid Cx. quinquefasciatus was also considerably greater (59%) for the BG-GATs than for BG2S traps (2%), but these relationships were not statistically significant due to high variability in collections between traps.
我们比较了Biogents孕蚊诱捕器（BG - GAT）和Biogents - 2哨兵诱捕器（BG2S）的功效，以评估佛罗里达州东北部这两种蚊虫监测方法在成蚊捕获率上的差异。BG2S诱捕器收集到的蚊虫种类多样性显著高于BG - GAT，前者诱捕到14种蚊虫，后者为4种。埃及伊蚊和致倦库蚊是两种诱捕器中捕获的两种主要蚊虫。总体而言，无论蚊虫种类如何，BG2S诱捕器捕获的蚊虫显著多于BG - GAT（在某些情况下几乎是其5倍）。在比较收集到的蚊虫总种类和数量时，两种诱捕器在孕蚊状态方面没有显著差异。然而，在物种层面，BG - GAT收集的埃及伊蚊中有8%为孕蚊，而BG2S中为1%。BG - GAT诱捕到的致倦库蚊孕蚊数量也比BG2S诱捕器多得多（59%对2%），但由于诱捕器之间收集情况的高度变异性，这些关系在统计学上并不显著。
