After its first detection in 2008 in the south German federal state of Baden-Wuerttemberg, another distinct population of the invasive Asian bush mosquito Aedes japonicus japonicus was unexpectedly found in western Germany in 2012. Range expansion had already been observed for the southern German population and was anticipated for the western German one.(More)
Adult females of two invasive species, Aedes albopictus and Aedes japonicus japonicus, were collected for the first time in July and August 2011 in Germany. Previously, only immature stages of these species had been found in the country. Repeated detection of these species reveals the Upper Rhine Valley in south-west Germany to be a particularly sensitive(More)
After two previous demonstrations of introductions of the Asian tiger mosquito, Aedes albopictus, into southern Germany in 2007 and 2011, another three specimens were trapped in the city of Freiburg in the Upper Rhine Valley. The females were caught in early September 2011 (n = 2) and mid-July 2012 (n = 1). The trap was located at a railway container(More)
After the repeated demonstration of Dirofilaria repens infections in German dogs, D. repens and Dirofilaria immitis DNA was detected in mosquitoes trapped in 2011, 2012 and 2013 in northeastern and southwestern Germany within the framework of culicid monitoring projects. As temperature is the most important factor dictating the extrinsic development of(More)
As a result of globalization and climate change, Dirofilaria immitis and Dirofilaria repens, the causative agents of dirofilariosis in Europe, continue to spread from endemic areas in the Mediterranean to northern and northeastern regions of Europe where autochthonous cases of dirofilarial infections have increasingly been observed in dogs and humans.(More)
A wide range of arthropod-borne viruses threaten both human and animal health either through their presence in Europe or through risk of introduction. Prominent among these is West Nile virus (WNV), primarily an avian virus, which has caused multiple outbreaks associated with human and equine mortality. Endemic outbreaks of West Nile fever have been(More)
The Asian bush or rock pool mosquito Aedes japonicus japonicus is one of the most expansive culicid species of the world. Being native to East Asia, this species was detected out of its original distribution range for the first time in the early 1990s in New Zealand where it could not establish, though. In 1998, established populations were reported from(More)
Within the framework of a national mosquito monitoring programme, a mosquito specimen collected in mid-2015 in southern Germany was identified as Aedes koreicus, a non-endemic species originating from East Asia. After the Asian bush mosquito Aedes japonicus, which is already established in Germany and widely distributed, and the Asian tiger mosquito Aedes(More)
The Asian bush mosquito, Aedes japonicus japonicus, a potential vector of several viruses, was first detected in Germany in 2008 on the Swiss-German border. In the following years, this invasive species apparently succeeded in establishing populations in southern Germany and in spreading northwards. In 2011, its distribution area already covered large areas(More)
Larvae, pupae and eggs of the Asian tiger mosquito Aedes albopictus were found in Freiburg, southern Germany, after submission of an adult mosquito specimen from that area to the ‘Mückenatlas’, a German instrument of passive mosquito surveillance. While previously collected Ae. albopictus in Germany were trapped on, or close to, service stations on(More)
