First record of Culiseta longiareolata ( Macquart ) for Germany

For decades the German Mosquito Control Association (KABS) has conducted mosquito surveillance as part of a comprehensive mosquito control programme. During the summer of 2011 hundreds of dead birds, especially blackbirds (Turdus merula), were found infected with the tropical Usutu occurred to investigate whether nulliparous mosquitoes carry the virus. More than 6.000 breeding sites were investigated most of which were infested with Culex pipiens/ Cx. torrentium virus (USUV, Flaviviridae) which is mainly transmitted by ornithophilous mosquito species such as Culex pipiens. Developmental stages of mosquitoes are collected in areas where dead birds populations and some with the invasive species Ochlerotatus japonicus japonicus. However, in one water container, in an open allotmentgarden located near Karlsruhe and the French border, third and fourth instar larva and five pupae of Culiseta longiareolata were found. Thus the number of mosquito species in Germany increases to 49 established species.
