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

Calculating the survival rate and estimated population density of gravid Aedes aegypti (Diptera, Culicidae) in Rio de Janeiro, Brazil

“…aegypti females, such as the number of bites per human per day and the duration of the extrinsic incubation period have not been estimated in Rio de Janeiro mosquito populations, with the particular climatic, socio-economic and host herd immunity status characteristics. The recapture rate observed in the neighborhood of Olaria was in accordance with several other mark-release-recapture experiments conducted in Rio de Janeiro 7,30 . Collections were performed by means of the daily aspiration of 30 houses and the inspection of 104 MosquiTRAPs.…”

Preliminary evaluation of the "Dengue-MI" technology for Aedes aegyptimonitoring and control

“…aegypti mosquitoes. Since the ideal place for setting the MosquiTRAP in households is outdoors (in the peridomicile) 11 , the trap is a non-invasive method 9 , i.e., the field inspector does not have to enter peoples homes, thus facilitating its use for monitoring. Since MosquiTRAP allows identifying the mosquito captured in the trap, without requiring additional procedures in the laboratory, the data collected in the field reaches the health system manager virtually in real time.…”

“…aegypti even during the dry season, when larval surveys do not detect the presence of larvae 8 . When compared to other methods for capturing adult mosquitoes, like the CDC backpack aspirator (Model 1412, John W. Hock Company, Gainesville, USA) 12 , the latter captured significantly fewer gravid females than the MosquiTRAP, whereas the Nasci captured a similar number 9 .…”

“…The method also requires laboratory personnel and only allows quantifying the number of eggs deposited, thus hindering estimation of the vector population density in a given area 4 . The backpack aspirator 9 and Nasci aspirator 10 have been used to capture resting adult Ae. aegypti, mainly outdoors, but with limitations, especially because the method is laborintensive and intrusive.…”

Olfaction in vector-host interactions

“…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.…”
