In Jiangsu high temperature, there are fewer mosquitoes?This is not an illusion, the reason is ...

Recently, Jiangsu's high -temperature weather has continued, and the heat is unbearable. Citizens feel that in addition to heat, it seems that mosquitoes are much less. Some netizens even said: "This may be a mosquito -free summer?" Is the mosquito really hot? actually not! It's just high temperature and rainy weather, which reduces the activity of mosquitoes. According to mosquito monitoring, from March to June this year, Jiangsu mosquito density is lower than previous years.

The temperature is high, the rain is small, and the activity of the mosquito is reduced

"I am very easy to recruit mosquitoes. In the summer, in order to wear skirts, all kinds of anti -mosquito tricks have been tried." Ms. Wang of Nanjing citizen said that at the end of June and early July, there were a lot of mosquitoes. "But this year entered this year. After summer, it was strange that I didn't feel the existence of mosquitoes. "Ms. Yang, who lives in Xuzhou, has recently found that there have been fewer mosquitoes. "My family lives in a low floor. Every summer, I have mosquito coils at the door of the house, otherwise the mosquito always goes to the house. The mosquito coils I bought this year are useless."

"According to the monitoring of mosquitoes in the province, mosquito density is lower than previous years from March to June this year. This is mainly because the mosquito is inseparable from the water body, but in recent months High, these are the unfavorable factor of mosquito raw reproduction. "Chu Hongliang, director of the Directory Disinfection and Media Bio of the Jiangsu Provincial Disease Prevention and Control Center, introduced. Excessive temperature or too low will reduce the activity of mosquitoes. "

The mosquitoes are not hot, they will find a place to "avoid summer"

Mr. Ji in Nanjing reported that after the summer of this year, the mosquitoes in the family were indeed much less than usual. However, in the wet places in the community, especially the shade and flower beds, there are still many mosquitoes.

"Temperature and rain are important factor affecting the number and activity of mosquitoes. If the precipitation is still small, the overall number of mosquitoes will be small. Even if the temperature drops to the comfortable range, the activity of mosquitoes will increase, and the mosquito may be mosquito may be mosquito. In addition, the overall number of mosquitoes has not increased. "Chu Hongliang said.

It is worth noting that the mosquitoes were not hot at high temperature, but they hid in the cool places such as grass, shade, and staircases. Therefore, the saying of mosquitoes is not accurate. It is just that high temperatures have led to less water on the road, and mosquitoes lack a good environment for spawning.

"Flower mosquitoes" in Jiangsu common mosquitoes are the most fierce

There are about 4,000 mosquitoes around the world, and about 400 species in my country. The types of mosquitoes in the Jiangsu area mainly include light -colored library mosquitoes, white -patterned mosquitoes, three beak library mosquitoes, Chinese mosquitoes, harassing A -mosquito, etc.

Among them, pale -color mosquitoes are the most common mosquitoes in the room. Most of them inhabits the wild during the day. They enter the indoor activity in the evening or at night, which are generally called "home mosquito". The larvae of the mosquito are generally born in a relatively dirty stagnant water. White -grained and mosquitoes are commonly known as "flower mosquitoes". Its female mosquitoes are mainly blood -sucking during the day, and they are fierce and are known as the "Asian tiger mosquito". The larvae are born in small containers, such as flower beds, tree holes, bonsai, blocked roofs. Most of the mosquitoes inhabited during the day, at night in livestock sheds or indoor. Its larvae are mainly born in large stagnant water, such as rice fields, swamps, reed ponds, slow flow ditch and other places.

According to Chu Hongliang, according to the monitoring results of mosquitoes in the province, mosquito density in rural areas in Jiangsu is higher than the urban area, especially the mosquito density of rural livestock sheds is relatively high.

The mosquito bites is also to bear the heavy responsibility of the next generation

Not all mosquitoes are bid. Studies have shown that mosquito sucking is not to fill the stomach, but to breed the next generation by the blood of people and livestock. Therefore, male mosquitoes eat nectar and plant juice; only female mosquitoes who have the next generation of fertility will bite.

Studies have shown that when mosquitoes are dingling, people's immune systems will respond to allergies to release a chemical named "histamine", which can separate the inner wall cells of the human blood vessels, which will cause some liquid to penetrate the skin into the skin of the skin. middle. These additional liquids infiltrated from the blood vessels form a drum bag on the surface of the skin, which causes stimulation to other surrounding feels and itching. The drums formed after children are bitten by mosquitoes are usually greater than adults. That is because children's immature immune system responses are more intense, secreting more histamine. Putting the mosquito bite will create more external stimuli, stimulate the human body to secrete more sets of amine, and the time required for redness and swelling will increase.

After the environment is comfortable, the mosquito may be active again, which requires scientifically

Mosquito is a dangerous animal, known as the largest killer in the animal world, which can spread infectious diseases such as dengue fever, malaria, epidemic encephalitis, Zika virus disease, and Ken Kong Kenya fever. Although the activity of mosquitoes has been reduced due to high temperature and rain in the near future, it is also necessary to be alert to the "comfort" of the environment.

Generally, the mosquito is inseparable from the water body. Without water, the mosquito cannot be born. Therefore, the raw water body to find and clean up the mosquito is a measure of controlling mosquitoes. "Scientists have been studying various new methods to deal with mosquitoes, have radiation to cause mosquito infertility, use the Volbak Austenity to control the number of Iraqi mosquitoes and reduce dengue fever.

How to scientifically prevent mosquitoes in life?Chu Hongliang introduced that a small amount of mosquitoes appearing in the home can choose to use electric mosquito, qi mist, electric mosquito and aromatherapy or electric mosquito fragrance tablets for killing.When going out, especially in the early morning and evening, avoid approaching grass, bushes, bamboo forests, etc. These are the habitats of mosquitoes; applying exorcists in bare skin to prevent mosquito bite.When a baby goes out, it is recommended to use gauze cover outside the hand.Xinhua Daily · Jiaojiao Reporter Hu Jingjing Wang Tian intern Li Wenyu
