update from March 11, 2019: new species of mosquitoes in Hesse settled
the Senckenberger Research Institute showed recently a population of Asian species of mosquitoes Aedes koreicus after in Hesse, Germany. The researchers think this heralds of a nationwide spread of the exotic mosquito in Germany. The new mosquito species was discovered already in the year 2015 in Augsburg, then in the year 2017 in Wiesbaden. Now, the research team in a recent study could again find larvae and pupae of the exotics.
“It is therefore likely that a whole population has wintered in Hesse and slowly starts this mosquito to spread in Germany”, explains Professor Dr. Sven Klimpel from the Senckenberg Research Institute. Aedes koreicus according to the experts, is considered as potential disease carriers. Mosquitoes can spread the virus of Japanese encephalitis as well as the Chikungunya virus. Furthermore, they are considered vectors of nematodes (Dirofilarien). The researchers presented their research recently in the journal “Parasitology research”.
strong spread of disease-carrying mosquitoes
diseases such as dengue fever, Zika, Chikungunya and yellow fever have become more deeply. Already, some tropical diseases have reached Europe. So the West Nile fever has spread in 2018 to Northern Italy and in the Czech Republic, mosquitoes have been discovered with the pathogen. A recent study examined the spread of the two most dangerous types of mosquitoes and comes to the conclusion that a plague of mosquitoes is upon us.
an international research team recently analyzed the imminent threat posed by diseases transmitted by mosquitoes. According to the researchers, climate change has created favourable conditions for the spread of dangerous mosquitoes. As well, the global mobility accelerates the spread of mosquitoes according to the study. In a few years will come every second person in the range of disease-transmitting blood-sucker, predict the study results, which were published recently in the prestigious journal “Nature”.
Egyptian and Asian Tiger mosquitoes on the rise
that Tiger mosquitoes of Aedes aegypti and Aedes albopictus are the world to the most dangerous types of mosquitoes. Countries with temperate climates such as Germany are been so far largely spared the dangerous mosquitoes, because these species only in warmer areas feel like at home. In the course of global warming, the Asian Tiger mosquito penetrate however in new habitats.
for every two people of tropical diseases will soon be threatened
the research group first identified the factors that favour the spread of the Asian Tiger mosquito. Then, the team with these factors calculated, as well as with the data on the spread of the last 40 years, as the mosquito will spread in the coming decades. “The models are forecasting that around half of the world’s population in the range of this species will live up to the year 2050”, so the researchers.
many urban areas are suitable as a Habitat for Tiger mosquitoes
“If no measures are taken to reduce the current climate, new habitats for the Asian Tiger mosquito will open up in many urban areas”, warns Dr. Moritz Kraemer of the University of Oxford (UK) in a press release on the study results. This could rapidly in the height, the spread of tropical diseases be quick and lead to real epidemics.
every year of 150 km of new European basin
which garnered team historical data of the mosquito types Aedes recreated and Aedes albopictus on over 3,000 sites in Europe and the United States, dating back to the 1970s. In a model, the researchers calculated what habitats are suitable in the year 2050, and in the year 2080 for the mosquito. Thereby, also common travel patterns and migration were taken into account. The researchers showed that in Europe the Asian Tiger mosquito at a frenzied rate spread. Every year the Habitat of the mosquito to about 150 kilometres stretches. In the United States, the mosquito even with a speed of 240 kilometers per year spread towards the North.
for Germany in particular, the Asian Tiger mosquito is according to a problem
the distribution model is the Egyptian Tiger mosquito mainly spread in southern Italy and Turkey, whereas is the Asian Tiger mosquito, Aedes albopictus is expected to spread across Europe. Within the next 30 years, large parts of France and Germany by the mosquito will be populated, so the researchers. The dangerous West Nile virus was already found in mosquitoes in the Czech Republic. As well, the virus on the Adriatic has spread greatly.

which factors are the strongest?
according to the analysis is driven by human movements spreading at the time the most. This change however: within the next five to 15 years. Then reach a point where the climatic conditions alone, the spread of the mosquito will push ahead with the gradual warming, predict researchers. “With this new work we can start suspecting how environmental changes will affect the transmission of diseases such as dengue and Zika”, added Professor Simon I. Hay of the University of Washington. He hopes that such information be included in future policy decisions.
recommend researchers urgently for the future an appropriate system for mosquito surveillance and control in all European countries, with emerging Aedes albopictus populations to establish. The further proliferation of Tiger mosquitoes could probably be prevented. Because the Asian Tiger mosquito can be eliminated so specifically. (vb)
