During 2009–2011, a total of 45 two-day captures of mosquitoes (Insecta: Diptera: Culicidae) were made at six sites in the Lower Dyje River Basin. Trapping was performed from early April through the end of October using Centers for Disease Control and Prevention (CDC) miniature light traps baited with carbon dioxide (CO2). In total, 415,218 female mosquitoes belonging to six genera and 30 species were captured. In early April, only small numbers of wintering species females (Culex pipiens s.l., Culiseta annulata and Anopheles maculipennis s.l.) were detected. From mid-April, there was a sharp increase in the occurrence of snow-melt species (Aedes cataphylla, Ae. intrudens and, sporadically, Ae. communis and Ae. leucomelas, totalling 2090 females). Their occurrence peaked in early May, but they gradually ceased flying in during June. Ae. sticticus females also became active starting in late April, while Ae. cantans s.l., Ae. vexans, Ae. rossicus and other species were active from early May. The greatest occurrence of mosquitoes was recorded in summer months (from mid-June through the end of August). In this period, the dominant species were Ae. vexans (49.70–80.20%) and Ae. sticticus (6.14–25.62%). The species Ae. rossicus, Ae. cantans s.l., Cx. pipiens s.l. and Cx. modestus also were very abundant from mid-June to late July. The occurrence of mosquitoes decreased rapidly during September. In the second half of October, only small numbers of Ae. vexans, An. claviger and Cx. pipiens s.l. females were captured, while Ae. cinereus s.l., Ae. rossicus, Ae. sticticus, Cx. modestus, An. maculipennis s.l. and An. plumbeus were seen only very sporadically.
