FIELD EFFICACY OF THE BG-SENTINEL COMPARED WITH CDC BACKPACK ASPIRATORS AND CO₂-BAITED EVS TRAPS FOR COLLECTION OF ADULT AEDES AEGYPTI IN CAIRNS, QUEENSLAND, AUSTRALIA

Abstract

In this study, we compared the efficacy of the newly available BG-Sentinel with an established "gold standard,", the CDC Backpack Aspirator, and a CO2-baited EVS trap for the collection of Aedes aegypti (L.) in Cairns, Australia. BG-Sentinels collected significantly more (P = 0.017) female Ae. aegypti (mean per collection, 1.92 +/- 0.39) than both the CDC Backpack Aspirator (1.00 +/- 0.35) and the EVS trap (0.71 +/- 0.27). Male-only and combined male-female Ae. aegypti collections for th BG-Sentinel and the CDC Backpack Aspirator were also greater than EVS trap collections. The CDC Backpack Aspirator and the BG-Sentinel captured proportionally fewer females compared with the EVS trap. The BG-Sentinel was the most Ae. aegypti specific collection method. The CDC Backpack Aspirator collected proportionally more bloodfed Ae. aegypti than the other methods, which collected a greater proportion of nullipars. The data presented here will aid researchers in deciding what Ae. aegypti sampling device best suits their needs. BG-Sentinels and CDC Backpack Aspirators should be considered as alternatives to human-bait collections for Ae. aegypti sampling.

Efficacy of Mosquito Traps for Collecting Potential West Nile Mosquito Vectors in a Natural Mediterranean Wetland

“…theileri) can be sampled with a similar efficacy using either BGS or CDC-CO 2 traps and that BGS traps are as useful for capturing Culex species (WNV vectors) as Aedes (Stegomyia) species. [23][24][25] The same conclusion is valid for Oc. caspius.…”

“…polinesiensis. [23][24][25] This type of trap can be used with a variety of mosquito attractants (e.g., CO 2 , BG-lure, or octenol), thereby making it a versatile tool for mosquito community research and surveillance. Nevertheless, only a few studies have investigated their efficacy regarding the capture of mosquito species other than those species of the genus Aedes.…”

Olfaction in vector-host interactions

“…Recent results from trapping with odour-baited MM-X or BG-Sentinel traps , Kröckel et al 2006, Njiru et al 2006, Williams et al 2006b suggest that the application of such traps, provided the odorant stimulus is highly competitive with natural host odour, are likely to become reality in the near future. Novel synthetic odorant blends that disrupt the natural behaviour of mosquito vectors may be used in addition to current control methods (Greenwood 2008, Takken and) to achieve a greater effect than is presently possible.…”
