People are bitten by mosquitoes in the summer, which is a very common thing, but there is a mosquito block that bites for several days and cannot retreat, and it is red, swollen and painful, it turned out to be bitten by "poisonous mosquitoes", Aedes albopictus.
Aedes albopictus, commonly known as "flower mosquito", mainly sucks blood during the day, bites people fiercely, spreads dengue fever, and is known as "Asian tiger mosquito". Breeds in naturally stagnant water and small containers, such as tanks, cans, can boxes, flower beds, bamboo tubes, tree holes, lunch boxes, waste tires, bonsai, clogged roof furrows, etc.
Mosquitoes that harass people at night are generally Culex mosquitoes, which do not transmit dengue virus, while spotted mosquitoes are mostly active during the day, 8-9 a.m., 5-6 p.m. is the peak time for spotted mosquitoes, this mosquito with black and white spots on the body can carry and transmit the virus for life, and can pass the virus to offspring through eggs.
Aedes albopictus is slightly larger, with white spots on its legs, which are usually found in places where wood is piled. In the south, there are mostly poisonous mosquitoes.
Mosquitoes in the bite of people will be toxins (mosquito acid) left in the human body, so that the skin overreaction---- itchy and red and swollen, really can't help scratching the skin, the tissue fluid and lymph fluid in the skin will penetrate out, swollen into a bag, because the blood skewer will spread the toxins, so it will cause the skin to appear part of the redness and swelling will not retreat for a few days, some will be a large piece, serious will make the entire leg swollen up.
Dengue fever cannot be directly transmitted between people and is transmitted by insect vectors, so in the prevention of dengue fever, dengue disease incidence monitoring and control to eliminate mosquito vectors is still the most effective preventive measure at present. Monitoring of Aedes mosquitoes is an important means of effectively warning of the occurrence of dengue fever and controlling the dengue epidemic. For a long time, the density of adult Aedes mosquitoes has been investigated, with Aedes aegypti mainly using the indoor habitat method and Aedes albopictus mainly using the human trap method, but both methods have shortcomings that may cause mosquito catchers to be bitten and infected with the virus. In addition, as long as the prevention and control of Aedes albopictus pays attention to it, the system is implemented, the measures are appropriate, and the persistence is persistent, it can be controlled to the extent of insufficient harm.
