Some will have already felt this summer in Germany, there are more mosquitoes than in years past. Doreen Werner of the Leibniz-centre for agricultural landscape research (ZALF) in Müncheberg, near Berlin, confirmed this. After two dry summers in a row, with significantly less mosquitoes in the exchange of humidity and heat this year was very mosquito-friendly, said the biologist of the German press Agency. "The harassment is regional but very different." Where heavy rainfall caused the water levels of the waters are rising, speaks of plague, the researcher of a mosquito. Examples are the Or, but also the lake Starnberger see and the Ammersee in Bavaria.
In Germany, home of the expert, according to over 50 species of mosquitoes. In the past two years were mostly house mosquitoes, which were about in rain barrels or puddles of their eggs. This summer, the so-called flooding, according to Werner mosquito boom. In flooding areas, for example the biologist per Minute registered a hint of more than 100 flood mosquitoes for receiving a blood meal. Of a plague, one can speak of approximately 20 mosquitoes per Minute. The Or led in the last few weeks of high water due to lots of rain, especially in southern Poland and the Czech Republic.
The water flow from the flooded areas and ditches in the floodplain forests and meadows not so fast, says Werner. There developed currently, mosquitoes are very good, the warm temperatures shortened their development time. Flood mosquitoes are very stechlustig, because they were under development pressure. According to the scientist, you need to suck in the shortest amount of time, blood, their eggs develop and then drop in order to allow over the summer, as many generations.
native mosquitoes Transmit pathogens?
The biologist uses the high mosquito emergence for their research. So you want to examine in a comparative way, if any of the local mosquitoes to transfer to the same extent as immigrant mosquitoes such as the Asian tiger mosquito, pathogen. Further studies would be carried out at the Friedrich-Loeffler-Institute (FLI), Federal research Institute for animal health,.
