Ochlerotatus japonicus japonicus - a newly established neozoan in Germany and a revised list of the German mosquito fauna

Abstract

The German Mosquito Control Association (KABS) has been conducting mosquito surveillance as a component of a comprehensive mosquito control programme since 1991. In this study, the results of the first 10 years of this century are presented. Approximately half a million mosquitoes were collected with CO 2 -baited adult traps, ovitraps and larval collections mainly in Southwest Germany and were identified to species. A total of 36 autochthonous species and two invasive alien species, namely Ochlerotatus j. japonicus [Hulecoeteomyia japonica sensu Reinert et al., 2006] and Aedes albopictus [Stegomyia albopicta sensu Reinert et al., 2004] were detected in Southwest Germany. Whereas Oc. j. japonicus is already widespread over an area of ! 10,000 km 2 in Southwestern Germany and is an established species, Ae. albopictus was found only in the egg stage in one ovitrap at a rest-area along a highway from Italy (via Switzerland) where Ae. albopictus is abundant. The latter was probably introduced into Germany by vehicles originating from Italy, whereas the
