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.
