Field evaluation of effectiveness of the BG-Sentinel, a new trap for capturing adult Aedes aegypti (Diptera: Culicidae)

in recent years, the development of new tools to gather field information about vector ecological parameters has increased. this report evaluated the bg-sentinel trap (bgs-trap), a promising new attempt to improve collection of the dengue vector, aedes aegypti. the efficacy of the bgs-trap was compared with the cdc backpack aspirator, one of the commonest used methods for capturing adult mosquitoes. bgs-traps captured significantly more ae. aegypti males (c2 = 21.774, df = 1, p < 0.05) and females (c2 = 56.007, df = 1, p < 0.05) than cdc aspirator during all days of field collection. however, cdc aspirator was significantly more efficient to capture culex quinquefasciatus males (c2 = 5.681, df = 1, p < 0.05) and females (c2 = 6.553, df = 1, p < 0.05). bgs-traps captured host-seeking females (varying between 68.75 to 89.8%) in detriment of females in other behavioral and physiological stages. bgs-traps proved to be efficient and can be used for monitoring adult mosquito populations.
