Why is "Autumn Mosquito" so powerful?

17-Sep-2021 AOGRAND
After the beginning of autumn, the weather gradually became cooler and dry, but instead of disappearing, the mosquitoes became more and more rampant. People say that "the most poisonous mosquito is not the autumn mosquito." If you are bitten by an autumn mosquito, the symptoms seem to be more serious. More importantly, these mosquitoes can carry various germs. Why do mosquitoes bite people so badly in autumn? The editor will take you to find out!

Why is "Autumn Mosquito" so powerful?
1. Appropriate temperature and humidity
After the beginning of autumn, the temperature difference between day and night is large, and the temperature is lower after nightfall, and its temperature and humidity are more suitable for mosquito activities. In early autumn, the temperature is mostly concentrated at 25~28℃, and the rain is abundant, which is beneficial to the growth and reproduction of mosquitoes. Mosquito density monitoring shows that the annual density distribution curve of mosquitoes is "hump-like". Due to the influence of sunny, hot and high temperature in June, many mosquitoes are "heated to death", but August and September are the peak of their activities.
2. Mosquitoes reserve energy for overwintering
Mosquitoes bite people harder after the beginning of autumn, which is to store energy for overwintering. When the temperature drops below 10 degrees Celsius, the mosquitoes will stop breeding. In order to "save their lives and reproduce", mosquitoes can only rely on frantically sucking blood to store a large amount of nutrients for the winter. Mosquitoes that are strong and suck more blood can survive the cold winter period.
3. Mosquitoes provide nutrition for reproductive offspring
Autumn is the peak period for mosquitoes to reproduce offspring. Mosquitoes are extremely active. These female mosquitoes are more aggressive when they lay eggs and provide more nutrition to their offspring. Therefore, mosquitoes bite more fiercely in autumn and are much more toxic than in summer.
Diseases transmitted by mosquitoes
In addition to biting and affecting people's work, study and life, mosquitoes are also the vectors of many infectious diseases and endanger human health. Mainly spread diseases such as malaria, dengue fever, Japanese encephalitis, chikungunya fever, Zika virus disease, yellow fever and West Nile fever.
The causative agent of malaria is a parasite called Plasmodium. Humans are infected by the bite of an infected mosquito. Malaria can occur throughout the year in tropical and subtropical regions. With the rapid development of inbound and outbound tourism, transnational trade, and foreign aid projects, a large number of inbound and outbound people are at risk of contracting malaria in malaria-endemic areas abroad.
The most effective way to prevent malaria is to prevent mosquito bites, such as using mosquito nets, window screens, mosquito coils, and repellents. Once fever or cold-like symptoms appear, go to the local hospital immediately. After malaria is diagnosed, follow the doctor's instructions to take the medicine in full and in sufficient quantities to avoid recurrence and drug resistance.
Dengue fever
Dengue fever is an acute infectious disease caused by dengue virus and transmitted by Aedes mosquitoes. The clinical manifestations of patients include fever, severe headache, orbital pain, musculoskeletal joint pain and skin rash, lymphadenopathy, etc.; severe cases have high fever, bleeding and shock, and the mortality rate is high.
At present, dengue fever is prevalent in all continents except Europe, mainly in tropical and subtropical regions of the world. The dengue fever outbreak in my country tends to move northward.
The main transmission vectors of dengue fever include Aedes aegypti and Aedes albopictus. The main transmission vector of dengue fever in mainland China is Aedes albopictus. Most of this mosquito species lives in various container-type water bodies in cities. The peak bites are concentrated in the morning or before dusk. Since the beginning of summer throughout the country, the density of mosquitoes has increased significantly due to the simultaneous rise of temperature and rainfall. Generally, the density of adult mosquitoes is highest in park green space, so when playing in the park green space environment, you must take measures to prevent mosquitoes.
Japanese encephalitis
Japanese encephalitis is an acute infectious disease caused by Japanese encephalitis virus with brain parenchymal inflammation as the main pathological change. The main symptoms are high fever, disturbance of consciousness, convulsions, meningeal irritation, etc., and the fatality rate is high, 30%~50% of cases have sequelae.
Culex tritaeniorhynchus is the main transmission vector of Japanese encephalitis. Mosquitoes bite animals infected with Japanese encephalitis virus and carry the virus, and then transmit the virus to humans through the bite. Summer and autumn are the prevalent seasons of Japanese encephalitis in northern areas, and adults are the main body of disease.
There is no specific and effective treatment for Japanese encephalitis, but it can be prevented by vaccinating children, preventing mosquitoes and mosquitoes. If you find early symptoms of Japanese encephalitis, such as high fever, headache, vomiting, fatigue, and lethargy, you should go to the hospital immediately to avoid missing the opportunity for treatment.
Mosquitoes pose a great threat to human health. Therefore, mosquito repellent is also one of the problems that people face in daily life. Among mosquito repellent products, the most commonly used mosquito repellent product is mosquito coils. Everyone knows that before mosquito coils are used, Read the label or instructions carefully, but there are still some misunderstandings in the actual use process.
Common misunderstandings in using mosquito coils
Misunderstanding 1: Use mosquito coils with doors and windows closed all night
In summer, the temperature is high. Many people turn on the air conditioner and close the doors and windows to sleep, stay in a closed environment all night, and use mosquito-repellent incense to repel mosquitoes at night. This usage is incorrect. The mosquito repellent liquid contains pyrethroid insecticides and other solvent ingredients. Pay more attention when using it, keep air circulation, keep the human head in the upper wind, and minimize the inhalation of the mosquito coil. If you turn on the air conditioner and close the doors and windows and use electric mosquito coils, pay attention to timely ventilation.
Misunderstanding 2: Use only a short while before going to bed
Some people find that there are mosquitoes at home, but don't want to keep the electric mosquito repellent liquid in them all night, so they only use it for 20-30 minutes before going to bed. Unexpectedly, I just fell asleep and was awakened by the buzzing sound in my ears. Is this mosquito-repellent incense ineffective? The truth is that the house has a large space, and the effective ingredients dispersed in the room can hardly reach a sufficient dose in a short period of time. The general electric mosquito-repellent incense liquid can be heated in a closed bedroom for two hours before the concentration of the drug in the air can achieve a good mosquito repellent effect. Therefore, it is recommended to heat the electric mosquito coils in advance two hours before going to bed and leave after sealing the house. After two hours, turn off the mosquito-repellent incense solution and ventilate the room to achieve a better anti-mosquito effect.
Misunderstanding 3: Smoked mosquito coils are effective
At present, the three common mosquito coil formulations on the market are: burning coil incense, electric mosquito coil sheet, and electric mosquito coil liquid. Combustion type coil incense will produce a variety of pollutants during the combustion process, while the electric mosquito coil sheet and electric mosquito coil liquid contain relatively simple ingredients, and do not need to use auxiliary materials to burn to produce smoke. The latter seems to be silent, but in fact it has the same effect as pan incense.
Considering the characteristics and convenience of various mosquito coil products, it is recommended to purchase and use in the following order: electric mosquito coil liquid, electric mosquito coil sheet, burning smokeless coil incense. If there are elderly, infants, and other people with weak physical fitness and respiratory diseases in the home, it is recommended to avoid using mosquito coils as much as possible to reduce health risks. You can use physical means such as mosquito nets and mosquito swatters to avoid mosquito bites and spend the autumn mosquito season safely.
