During 2009 and 2010, 23 night-time mosquito captures were made at Kančí obora in south-eastern Moravia, Czech Republic. It was used in the Centers for Disease Control and Prevention (CDCP) miniature light traps with CO2 (dry ice) and baited lard-can traps in which sentinel animals were replaced with a container filled with CO2 (dry ice). In the observed period, a total of 31,882 female mosquitoes were captured by CDC miniature light traps with CO2. Lard-can traps baited with CO2 captured 995 females under the same conditions, which is just 3.12% of the quantity from the CDC traps. At the same time, there were significant differences in the proportional captures of various species. Compared to CDC miniature light traps, baited lard-can traps much more often captured Aedes cinereus (16.58% of total versus 1.93% in CDC traps), Culex modestus (15.48% versus 4.62%), and Ae. rossicus (6.13% versus 2.67%). On the other hand, capture of female Ae. vexans was proportionally much lower (15.38% versus 36.41%). Capture of Cx. pipiens was more or less the same 14.77% (miniature light traps) and 15.76% (baited lard-can traps). The occurrence of the calamity species Ae. sticticus was proportionally very high in both trap types (30.05% in lard-can traps baited with CO2, 33.58% in CDC miniature light traps). The findings prove that a trap’s design itself significantly affects not only the overall capture of mosquitoes but also the proportional representation of individual species.
