Abstract
In order to improve the limited database on species inventories and ecology of Culicidae in Austria, we monitored hydrological and physico-chemical parameters of breeding habitats of the Culicidae species of Danubean wetlands from March to October 2011 in the National Park Donau-Auen (Lower Austria). A total of 34 eggrafts, 1022 larval, 80 pupal, and 221 adult Culicidae were collected. We detected 15 mosquito species belonging to the genera Anopheles Meigen, 1818, Culex Linnæus, 1758, Culiseta Felt, 1904, Coquillettidia Dyar, 1905, Aedes Meigen, 1818 and Ochlerotatus Lynch Arribalzaga, 1891. In the larval and pupal stage, Ochlerotatus geniculatus (Olivier, 1791) (64.1%) and Culex territans Walker, 1856 (18.7%) were most abundant. Based on abiotic and biotic parameters, sampling sites were grouped into four clusters. The results show that water level and -persistence, pH, conductivity, and phosphate concentrations had a significant influence on species distribution, and that floodplain dynamics are a key factor for the seasonal and spatial distribution of mosquito larvae in the National Park.
