This year, Ji'nan's mutant mosquitoes are very toxic experts say climate change is the main cause.
with the idea of "freezing a lot of mosquitoes" in the cold winter of the beginning of the year, Ms. Joe did not prepare mosquito incense as early as it was in the past years. But two days ago, her daughter was attacked by a mosquito.
director of the center for biological media prevention and control of the city center for disease prevention and control said, "don't look down on mosquitoes. They not only try to escape the cold winter attacks of the year, but they have been mutated, and this year will be very poisonous and arrogant."
urticaria may be mosquito bites
early in June 20th, Ms. Joe, who lived in the North Road of Qianfo Hill, found two spots on her face, three and a half years old, like anaphylaxis. She took the baby to the hospital. The doctor looked at it and said, "these are mosquito bites!"
Xin Linlin, director of Department of dermatology at the hospital in Qianfo Hill, Shandong, said that in June, as the mosquitoes began to start, people suffering from papular urticaria were significantly more, eight or nine of them were children. "Children can not stand itching, especially like catching, when serious blood is caught. So tender skin, it really hurts. " Xin Linlin said that papular urticaria is bitten by mosquitoes, and some infectious diseases are more difficult to say, like encephalitis B, malaria and other summer infectious diseases, which are spread by mosquitoes.
weather abnormalities lead to reproductive active
research data show that, under the influence of climate change, the mosquitoes in Ji'nan have been mutated and more toxic this year. If the control is not effective, it will aggravate epidemic situation such as encephalitis B and dengue fever.
an expert review of a mosquito gene study in the province of the CDC in May showed that Ji'nan mosquitoes have produced genetic variations under the pressure of climate change and insecticide, and the next generation.
mosquito variation is mainly caused by weather anomalies. Although the cold winter is very unusual this year, cunning mosquitoes know how to protect themselves indoors and freeze to death. The warmer weather has led to more mosquitoes. "Coupled with cold and hot weather, the ecological environment formed is more suitable for mosquito breeding."
and the doctor also confirmed that the mosquito is very poisonous this year, and the bites are very itchy, and it will take a long time to retire.
, however, Xin is saying that the number of mosquitoes will not increase significantly this year, almost the same period last year.
this year, the two species of mosquitoes are particularly vicious
"at the same time, we should be alert to the phenomenon of" raising mosquitoes in high buildings. " Xin Zheng said, now many communities are multi-storey, small high-rise buildings. Many mosquitoes follow the elevator up and down, and drill into the top occupants' homes.
Xin Zheng said that the mosquito species encountered this year will also be different. According to last year's monitoring, there are three species of mosquitoes in Ji'nan, including 35% of Anopheles, 21% of Culex pipiens pallens, and 17% of Aedes albopictus. "
" and Anopheles mosquitoes will decrease this year, and Culex pipiens pallens and Aedes albopictus are both the majority. These two kinds of mosquitoes like this person to kiss, bite that person, so the spread of disease is particularly strong.
before sunrise, killing mosquitoes is best after
Ji'nan has 15 mosquito monitoring sites, including green space, residential areas, hospitals and so on. In the past, the density of mosquitoes in the greenbelt was relatively high, especially in Quancheng Park and Daming Lake, and there were more mosquitoes in the water. Now, the hygiene of these places is good, and mosquitoes are also decreasing.
Xin Zheng said, "which place is a little lax, hygiene is not done well, mosquitoes will get more." Especially in the basement and underground garage of new residential areas, mosquitoes breed quickly in some wells and open trenches.
there are two peaks of mosquito breeding in Ji'nan, one in June, and the other in 8 and September. Mosquitoes are most effective in mosquito control at this time of day, before sunrise and after sunset. We should seize this opportunity to spray mosquitoes or apply soap bubbles to the washbasin to kill a large number of adult mosquitoes.
