New mosquito in Brandenburg: Anopheles Hyrcanus alerts experts!
In Brandenburg, a new mosquito species, the anopheles hyrcanus , was discovered. Doreen Werner, a biologist and entomologist, was able to demonstrate this kind in Oderbruch. This mosquito is originally widespread in southern Europe, especially in Spain and Portugal, and is increasingly wandering north through climate change. A total of 62 copies of anopheles Hyrcanus were caught as part of the mosquito monitoring. This type of mosquito is characterized by its black and white spotted wings, which it clearly distinguishes it from domestic species.
The anopheles hyrcanus , like all mosquitoes of the genus of Anopheles, is theoretically able to transmit malaria. In Germany, however, eight other species of anopheles are already known that act as more effective carriers. Werner calms down that there is no fear of this new mosquito species. According to her, those affected should see a doctor for unusual symptoms of illness after a mosquito bite. To protect herself from stitches, she recommends wearing long clothing and avoiding scratching.
transmission paths and reproduction
The anopheles mosquito belongs to the class of insects and is one of the most dangerous transfers in malaria, one of the most feared diseases worldwide. Of the approximately 420 species within this genus, around 40 are known as malaria -transmitting. Males and females of the mosquito feed on plant juices, whereas the females need a blood meal for reproduction.
The process of transmission of malaria is mostly via two ways. The most common way is that the mosquito absorbs infected blood, increases the pathogens in their own body and then infected a new victim at the next blood meal. The millimeter -sized sting takes place by injecting a glandular secretion that inhibits blood clotting and increases blood flow. This saliva can also contain dangerous pathogens.
climate change and spread of malaria
An important factor for the spread of the anopheles hyrcanus and other mosquito types is climate change. This leads to a statistically significant change in the climate over several decades, which not only influences temperatures, but also rain patterns and other environmental conditions. This creates ideal living conditions for mosquitoes and favors the transfer of malaria in new areas.
According to a study by the University of Zurich, the high -risk season for malaria has extended to up to six months due to climate change. This is worrying because Malaria was eradicated in Europe in 1975 and recently performed sporadic cases again. High temperatures also shorten the growth cycles of the malaria parasite, which means that mosquitoes can infect faster.
The effects of climate change are not only limited to health; They also disturb the social structure and access to necessary health resources. Extreme weather events can affect transport routes and make the distribution of medication and vaccines difficult. Therefore, increased formation of consciousness about the changes in malaria risk areas is essential.
The Mückenatlas project, in which Doreen Werner from the Leibniz Center for Agricultural Landscape Research (ZALF) in Müncheberg is also involved, enables citizens to send mosquitoes to identification and actively contribute to monitoring these new developments.
