Field Comparison of Novel and Gold Standard Traps for Collecting Aedes albopictus in Northern Virginia

Abstract

Aedes albopictus is a potential West Nile virus bridge vector in Northern Virginia; however, information regarding its virus transmission dynamics is limited, as this species is not readily collected in existing traps. This study used 5 replicates of a 5 x 5 Latin square to evaluate the efficiency and effectiveness of 2 novel host-seeking mosquito traps (the BG-Sentinel and the Collapsible Mosquito Trap (CMT-20) in collecting Ae. albopictus, relative to a carbon dioxide (CO2)-baited Centers for Disease Control and Prevention (CDC) miniature light trap. When used with CO2, the BG-Sentinel (with BG-Lure) collected 33 times more female Ae. albopictus per 24-h trapping period than did the CO2-baited CDC light trap. Without CO2, the BG-Sentinel (with BG-Lure) still collected over 6 times as many female Ae. albopictus as the CO2-baited CDC trap. Both configurations of the BG-Sentinel were significantly more effective than the other traps. The BG-Sentinel was also significantly more efficient in collecting Ae. albopictus and collected a high proportion of this species, both with CO2 and without CO2. The CMT-20 (with SkinLure) collected significantly more Ae. albopictus when used with CO2 than without CO2, but did not collect significantly more Ae. albopictus than the CO2-baited CDC light trap. The proportion of Ae. albopictus collected in the CMT-20 with CO2 and without CO2 did not differ significantly from the proportion of Ae. albopictus collected in the CDC trap.

Olfaction in vector-host interactions

“…A new ventilator trap (BG-Sentinel™) used with a combination of odorant substances found on human skin focuses on host-seeking dengue mosquitoes. The BG-Sentinel trap has been shown to have much better catching rates than conventional traps (Kröckel et al 2006, Meeraus et al 2008. Both trap types allow for more specific and refined vector control campaigns in situations where the traditional tools are often marginally effective.…”

“…albopictus was found in BG-Sentinels placed in Libreville, Gabon (Krüger and Hagen 2007). A study comparing the CDC Light trap baited with carbon dioxide to the BG-Sentinel and another new trap, the CMT-20TM was published by Meeraus et al (2007). The BG-Sentinel baited only with the BG-Lure captured six times more Ae.…”

“…aegypti (Feltner and Ferrao 2008, Krueger and Hagen 2007, Maciel de Freitas et al 2006, Meeraus et al 2007, Morrison et al 2008, Williams et al 2007, Solberg et al 2007. Kröckel et al (2006) compared the BG-Sentinel to the Fay-Prince trap and a trap that produces carbon dioxide through the combustion of propane gas (the Mosquito Magnet Liberty™), and human landing collections in Belo Horizonte, Brazil.…”

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

“…Nevertheless, only a few studies have investigated their efficacy regarding the capture of mosquito species other than those species of the genus Aedes. [26][27][28] However, biases related to mosquito diet in the fraction of blood-fed females captured could have major implications for the analyses and interpretation of data originating from mosquito bloodmeals. Indeed, some authors suggest that the synergistic effect of octenol (1-octen-3-ol) and CO 2 significantly increases the capture of mosquitoes that feed on mammals.…”

The impact of CO2 on collection of Aedes aegypti (Linnaeus) and Culex quinquefasciatus Say by BG-Sentinel(r) traps in Manaus, Brazil

“…aegypti than CO 2 -baited encephalitis vector surveillance traps ) and significantly more female Ae. albopictus than CO 2 -baited CDC traps (Meeraus et al 2008), but the effect of CO 2 on catch rates of BGS traps for urban mosquitoes, mainly Ae. aegypti and Culex spp, has not been investigated in Brazil.…”
