There are more than 2,000 kinds of mosquitoes in the world, China has found more than 300 kinds. Culex, Anopheles and Aedes are the three main blood-sucking mosquitoes, but also the most common mosquitoes. These three kinds of mosquitoes generally do not fly high, 6 floors above the mosquito will be significantly reduced, high-rise mosquitoes, mostly "by" the elevator up
Culex mosquitoes, also known as house mosquitoes, it is mainly in the dusk after the bite of human and livestock, easy to disseminate encephalitis B. However, the Culex mosquitoes are also three kinds of mosquitoes, the mosquitoes are also three kinds of mosquitoes. However, the Culex mosquito is also the three kinds of mosquitoes in the most stupid, it likes to go out after the lights out, before biting people first in the skin pick and choose, so it stops to come, sensitive people have a sense of slap, it is no "murder" opportunity
By the mosquito wings have black and gray spots. Resting, the head close to the ground, the abdomen up, the body and the object surface into 30-45 degrees oblique angle, while the Culex mosquito, Aedes aegypti resting when the body and the object surface hold a parallel position, so it is easy to distinguish. Anopheles mosquitoes mainly in the dawn attack on humans, the main transmission of malaria and filariasis. Anopheles mosquitoes are less cunning than Aedes aegypti mosquitoes, and so people feel, it has not sucked the blood but has been under the mouth to bite, then even if it killed it, the skin will still be a bag.
The Aedes aegypti mosquito is often referred to as the "flower foot mosquito", can spread B encephalitis and dengue fever. The dengue fever outbreak found in Cixi, Zhejiang Province, last year was due to the spread of Aedes aegypti mosquitoes. Aedes aegypti mosquito bite, people usually do not feel, to have an itch, it has "eaten and drunk" fly away. Aedes aegypti mosquitoes are mostly active during the day.
On the flavor of less fear of being bitten by mosquitoes
Mosquitoes bite people affected by three major factors. First, the respiratory tract exhaled carbon dioxide is a mosquito directed odor source, mosquitoes with which to find people, and then under the mouth bite.
The second is heat. Fat people are more likely to be mosquito bites, dark-colored clothes absorb heat, but also easy to attract mosquitoes.
The third is feces. Mosquitoes love to bite people with rough pores and sweat, and generally men are more likely to attract mosquitoes than women, youth than the elderly, and healthy people than patients. Children's metabolism is strong, is also the object of mosquito favor. In addition, when women come to menstrual period, the secretion produces changes, more mosquitoes. Exercise sweat, but also more mosquitoes, so it is best to quickly take a shower after exercise, less sweat, mosquitoes will bite less.
Several ways to deal with mosquitoes
Break off breeding water. Mosquitoes early in the development of eggs, larvae, pupae live in the water, as long as the cut off their breeding water, mosquitoes can not reproduce. Depending on the temperature, the incubation period of mosquito eggs is 7-14 days. So, deal with stagnant water and pack up the altar jars placed in the open. If you have aquatic plants in your home and office, remember to change the water once every two days, otherwise mosquitoes will breed easily. Raising fish in the water is also a good idea, because mosquito larvae tsetse is exactly what small fish love to eat. Floor drains, sewers and other places to prevent the accumulation of water, and from time to time to spray some insecticides, not to give mosquitoes living environment.
Screens and mosquito nets. Families with pregnant women or young children can choose to avoid the impact of mosquito coils and insecticides on the human body.
Mosquitoes, insecticides should always change the brand. Mosquitoes, like germs, can produce drug resistance, the CDC has monitored the population of mosquitoes resistant to a certain insecticide. A kind of insecticide or mosquito incense long-term use, it is likely that the mosquitoes in a certain area of drug resistance, so every once in a while to change a brand to use.
When traveling in the summer, wear long-sleeved shirts and long pants for protection. On exposed skin, apply mosquito repellent every 4 hours or so.
Wear light-colored clothes. Aedes aegypti mosquitoes like to stop at black clothes.
Bath with less soap. Mosquitoes love nectar dew, and the probability of being bitten by mosquitoes rises after using perfumes, cosmetics, creams and other items with floral scents, with the exception of sandalwood.
Eat more vegetables. Some vegetables contain odors that mosquitoes don't like, such as vegetables containing carotene and garlic and other vegetables with a pungent flavor, etc., and mosquitoes will stay away from you after a person eats them.
No scratching after being bitten. After scratching, the skin tissue fluid, lymphatic fluid and other oozing, swollen into a bag, it will be more scratching the more itchy, but also not easy to subside, full of red "red bean legs" is so scratched out. If you insist on not scratching, usually after 10 to 15 minutes, the itch will be able to obviously subside.
In addition to encephalitis B, dengue fever and other diseases, foreign mosquitoes are also spreading an epidemic called "West Nile fever". Mosquitoes, especially Culex mosquitoes, are the main vectors of the disease, which is named for the blood of a febrile woman in Uganda's West Nile region, where it was first isolated in 1937.
Previously endemic only in Africa, West Asia, and the Middle East, West Nile fever was introduced to Europe in the early 1960s and spread in the United States and other countries in the late 1990s. Most people infected with West Nile virus do not experience serious symptoms, which can include fever, headache and muscle pain, sometimes a skin rash and swollen lymph nodes. In severe cases, in addition to headache and high fever, there is cervical rigidity, trance, disorientation, tremor, convulsions, muscle weakness or muscle paralysis, coma, and occasionally death. The largest human epidemic to date occurred in the Cape Province of South Africa in 1974, with more than 3,000 clinical cases reported. In recent years, it has suddenly begun to appear and become widespread in the U.S. Since mid-August 2003, West Nile virus has spread rapidly in the U.S., with 28 deaths as a result.
The virus has not yet been found in China.
