Die Rolle der Globalisierung und Klimaveränderung auf die Entwicklung von Stechmücken und von ihnen übertragenen Krankheiten in Zentral-Europa

Abstract

Mosquitoes and mosquito-borne diseases know no borders, and their spread is a consequence of globalization related to high mobility of humans and international trade as well as on climate change. Higher temperatures and precipitation favour the development of mosquitoes as well as the pathogens and parasites which are transmitted by mosquitoes. An increase of about 2 °C would shorten the time for the development of larvae and pupae of Anopheles messeae (vector of malaria) by almost three days resulting in an increase of gonotrophic cycles and number of generations. The higher numbers of breeding sites for Anopheles species such as An. plumbeus in cess pools due to the change of agricultural practises increase the contact with potential vectors of malaria as well. However, at least in Germany, malaria will not play an important role anymore. The invasion of new species such as Stegomyia albopicta (formerly Aedes albopictus) is enhanced by human migration and international trade. St. albopicta was first discovered in Germany in 2007. Nowadays, this species, originally from Southeast Asia, occurs in 13 European states. Thus, the risk for outbreaks of arboviroses is increased. © Springer-Verlag 2009.
