How did you get here?

Mosquitoes go through four stages of egg, larva, pupa and adult. They like to lay their eggs in clear water, such as stream water, Rain Water depression, ponds, marshes, rice fields and mountain streams. They can hatch into larvae in about three days in the warm season and begin to grow in draught. Tiny microbes and protozoa. After molting, the wiggler finally stops eating and becomes a pupa with less activity. About two or three days later, the pupa came to the surface to shed its skin and feathered into an adult to fly out, becoming the most annoying mosquito.

The specific growth process:

1. Mosquito eggs: eggs are the beginning of mosquito growth. The eggs of Anopheles and domestic mosquitoes hatch in about two days, while those of Aedes albopictus hatch in three to five days. Each female mosquito lays a total of about 1000 to 3000 eggs in a lifetime.

2. Larvae: mosquito larvae breathe through straws and feed on organic matter and microorganisms. The bristles of the mouth will produce water and flow to the mouth. This period lasted for about 10-14 days and became pupa after molting for 4 times.

3. Mosquito pupae: the shape of mosquito pupae looks like a bean spot from the side and does not feed, but it can swim in the water and breathe on the first pair of breathing horns. After two days of full maturity, it molts and feathers into adults.

4. Adults: newborn mosquitoes cannot take off before Eclosion. Males mate within 24 hours after Eclosion. Mating usually takes 10-25 seconds. The female mosquito only copulates once in its life, and the eggs produced by the female mosquito can be fertilized.

How long is the life span?

Under natural conditions, the life span of mosquitoes is about 7-10 days after mating, while females generally live for 1 to 2 months.

What are you afraid of?

Plants:

1. Garlic: garlic will give off a prickly smell, and the mosquito repellent effect is also very good. After eating garlic, people will secrete a taste, mosquitoes will stay away, and friends who like to eat garlic will get an unexpected harvest. Garlic can also be sliced, placed in the window or smeared on the screen to prevent mosquitoes from entering the room.

2. Orange peel: after eating the orange, put the orange peel on the window or on the balcony to dry. Order orange peel at night, orange peel burning smell, mosquito repellent effect is quite good. And the orange peel is quite fragrant!

3. Nocturnal incense: nocturnal incense is a good mosquito repellent plant. Plant a few pots of nocturnal incense at home, or plant some in the yard. Summer can not only drive mosquitoes, but also be a scenery!

Lavender: lavender is an effective mosquito repellent and can also kill mosquito larvae, so it is also a good choice to plant a few lavender at home in summer.

5. Lotus plants: a new study published in the Asia-Pacific Journal of Tropical Medicine found that lotus and other lotus plants are effective mosquito repellents and can also kill mosquito larvae. Therefore, you might as well raise some small lotus plants at home in summer.

6. Cat mint (also known as camphor grass): a study by Ohio State University in the United States found that cat mint can scare mosquitoes, and its essential oil is 10 times more effective than mosquito repellent dew.

7. Black pepper: the study also found that black pepper also has obvious mosquito repellent effect. Usually it can be scattered on the window, door or the edge of the flowerpot to prevent mosquito breeding and invasion.

Animals:

1. In the water: fish, tadpoles, water fish (dragonfly larvae).

2. Land: frogs, toads and other amphibians, gecko, lizards and other reptiles, spiders and other arthropods.

3. The sky: bats, dragonflies, small insectivorous birds (such as swallows, sparrows, etc.).

Chemicals:

1. Insecticides: pesticides are the most direct and effective way to kill mosquitoes directly. However, friends who have used pesticides must not like the smell of pesticides, and people smell a little dizzy, so it is not an environmentally friendly way. After use, pay attention to ventilating the house and beware of poisoning.

2. Mosquito-repellent incense: mosquito-repellent incense can burn all night. The editor has used it before. Dish-type mosquito-repellent incense works very well and is relatively cheap. But some friends don't like the smell of mosquito-repellent incense. When sleeping, pay attention to the ventilation of the room. I think mosquito-repellent incense is a little harmful.

3, wind oil essence: wind oil essence or cool oil, many friends have used, painted to chilly, in fact, it has another effect, that is, mosquito repellent. Wind oil essence gives off the smell, mosquito repelling effect is quite good! At the bedside, under the bathroom and under the sofa, put two or three boxes of open essential oil, mosquitoes smell and fear, do not run away.

5. Smoke: when I was a child, when I was enjoying the cool outside at home, I tied the straw into a thick braid, and then put it in the limelight in the yard. The thick black smoke blew along with the wind, and the mosquitoes had long been dizzy, so they didn't have time to bite!

What blood type is the most attractive to mosquitoes?

1. Type O blood: miserable type 0 blood is the favorite of all mosquitoes. Can't you see that this is the blood type that a group of people sit together and are bitten desperately by mosquitoes? the most outrageous thing is that even applying anti-mosquito lotion and ordering mosquito incense will not work. Mosquitoes even don't let go of their eyelids and lips, leading to the cup of "disfiguring" the next day.

2, type A blood: this blood type, you can rely on mosquito incense to stop the fierce attack of mosquitoes, compared to type O blood is still relatively safe, however, the application of anti-mosquito lotion is not effective, mosquitoes will still bite.

3, AB blood: mosquitoes still have a little love for this blood type, especially after exercise, mosquitoes especially like to fly over to bite you, that taste, sweat BMW!

4. Rh negative blood type: this is the panda blood type among all blood types. There are only a dozen of these blood types in more than 100,000 people, and there are very few of them. Mosquitoes are not very attracted to this blood type and will not pursue it as hard as the above blood types.

What kind of people do you like to bite?

1. Mosquitoes like people with well-developed sweat glands and high body temperature: people who like to sweat, the acidity in the blood is enhanced, and the sweat excreted makes the body surface lactic acid higher, which is attractive to mosquitoes. In addition, there is a heating body in the mosquito's antennae, which is very sensitive to temperature. As long as there is a slight temperature difference, you can immediately detect that the sweating human body dissipates heat quickly and will also attract mosquitoes.

2. Mosquitoes like people who are tired or breathe faster: mosquitoes find their prey by smell. Carbon dioxide has a strong attraction to mosquitoes. Mosquitoes have carbon dioxide receptors on their small tentacles, which can sense substances such as carbon dioxide and lactic acid. The carbon dioxide emitted by a person's breath can be detected by mosquitoes at a distance of 15 meters. After engaging in sports or manual labor, people's breathing will speed up, at this time the exhaled carbon dioxide is relatively large, and the carbon dioxide gas will form a moist and warm airstream about 1 meter above the head, to which mosquitoes are more sensitive. Will smell and come. By the same token, people with large vital capacity or faster breathing rhythm exhale more carbon dioxide, and mosquitoes come in groups when they smell it.

3. Mosquitoes like people who wear dark clothes: because black is the first choice for mosquitoes to attack, such as Aedes albopictus (also called flower mosquitoes), they prefer to park on black clothes. Followed by blue, red, green and so on, mosquitoes do not like people who wear white clothes. In the same way, mosquitoes like to bite people with darker skin or reddish skin.

4. Mosquitoes like people with fast metabolism: generally speaking, men attract mosquitoes more than women, young people than old people, and healthy people than sick people, because there are more secretions on the surface of the skin. Women in the period, secretions change, but also more attractive mosquitoes. Mosquitoes have "food tropism". This is not because people think that some people have delicate skin and sweet blood to attract mosquitoes. The main reason is that some smells on their bodies attract mosquitoes.

5. Mosquitoes like pregnant women: pregnant women are very easy to attract mosquitoes. Pregnant women are particularly attracted to mosquitoes, and they are twice as likely to be bitten by mosquitoes as other women, according to a US medical study.

Why suck people's blood?

In fact, only female mosquitoes suck blood, but males do not, because female mosquitoes must suck blood to their ovaries to develop and reproduce. Most female mosquitoes begin to suck blood 2-3 days after Eclosion. Temperature, humidity, light and other factors can affect the blood-sucking activity of mosquitoes, usually when the temperature is above 10 ℃. However, Aedes albopictus mostly sucks blood during the day, Anopheles mosquitoes and Culex pipiens mosquitoes suck blood at night, some are partial to human blood, and some mosquitoes like to suck the blood of livestock, so mosquitoes can spread zoonosis.
