The selection of the ideal trap for arbovirus surveillance is an issue of primary importance to increasethe sensitivity of virus detection and the cost-effectiveness of the entomological surveillance. Duringthe summer 2011, the effectiveness of five types of mosquito traps (CDC gravid trap, CO2-baited trap,BG-SentinelTMand two experimental prototypes) to attract females potentially infected with West Nilevirus were assessed. The study was carried out in three natural wetland sites located in the Emilia-Romagna Region (Northern Italy), using a Latin square scheme. Single night collections of adult femaleswere performed and determination of species and physiological state (gravid, nulliparous or parous) wasmade upon return to the laboratory. The species most frequently collected in the gravid trap was Culexpipiens sl. L., being gravid females the large majority of the individuals. Species diversity was much higherin CO2-baited traps, which may therefore enable a more comprehensive description of the vector speciescomposition and their role in arboviruses circulation. Our findings indicate that gravid traps can be avalid tool and should be integrated in the West Nile virus surveillance system in the Emilia-Romagnaregion, mainly based on collections made with CO2-baited traps.

Abstract
The selection of the ideal trap for arbovirus surveillance is an issue of primary importance to increasethe sensitivity of virus detection and the cost-effectiveness of the entomological surveillance. Duringthe summer 2011, the effectiveness of five types of mosquito traps (CDC gravid trap, CO2-baited trap,BG-SentinelTMand two experimental prototypes) to attract females potentially infected with West Nilevirus were assessed. The study was carried out in three natural wetland sites located in the Emilia-Romagna Region (Northern Italy), using a Latin square scheme. Single night collections of adult femaleswere performed and determination of species and physiological state (gravid, nulliparous or parous) wasmade upon return to the laboratory. The species most frequently collected in the gravid trap was Culexpipiens sl. L., being gravid females the large majority of the individuals. Species diversity was much higherin CO2-baited traps, which may therefore enable a more comprehensive description of the vector speciescomposition and their role in arboviruses circulation. Our findings indicate that gravid traps can be avalid tool and should be integrated in the West Nile virus surveillance system in the Emilia-Romagnaregion, mainly based on collections made with CO2-baited traps.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
