We are talking about an insect that thrives with temperatures of 20-25 ° C and is able to survive the winter if the January temperatures never drop below 3 ° C. It is clear that in a context of global warming, an insect of this genus can easily move from north to south and survive even the cold seasons.
For the European Public Health Week 2020 , the Flemish Institute for Technological Research ( VITO ) used data from the Copernicus Climate Change service to create a tool that shows us how future climatic conditions in Europe will help spread the tiger mosquito.
One of the most important applications of the model is the healthcare sector , where obviously influenced by climate change. VITO has developed a series of tools that allow it to adapt to rising temperatures, changes in concentrations of pollen and allergens and diseases transmitted by mosquitoes .
The distribution of the tiger mosquito is already expanding due to human activities such as the shipment of car tires, which contain small bodies of water inside them or the ideal habitat for the reproduction of these insects. But its spread is also strongly linked to weather conditions, in particular to temperature and rainfall. It is evident that with increasing global temperature and the change in the pattern of rainfall distribution, insects originating in the tropical and subtropical areas of Southeast Asia are slowly moving north and towards Europe.
The female mosquito feeds as we know on the blood of humans and is responsible for the transmission of a variety of viruses such as Zika , Chikungunya and Dengue . The latter two are already infecting Europeans and this makes the spread of the tiger mosquito a real concern.
