Mosquitoes can spread diseases, so every summer and autumn, the staff of the city's disease control department should monitor local mosquitoes. In the event of a mosquito-borne case, CDC staff can provide data support to prevent the spread of mosquito disease through monitored data. At the same time, the agent for killing mosquitoes is improved.
M-Toluic Acid CAS 99-04-7 factory told us that In order to catch mosquitoes, leeches, test tubes and mosquito nets have come in handy. They usually take leeches to rivers, ponds and villagers' tanks to find larvae. In the reservoir, in order to avoid water waves and shock the mosquito larvae, they once every 10 meters to observe whether there are larvae, quantity, species and so on. They often choose a fixed period of time, revealing their calves next to the grass, enticing the mosquitoes to bite themselves, and then collecting the mosquitoes with a mosquito. "Professional mosquito trappers" also sit in double-layer mosquito nets at the peak of mosquito infestations. Mosquitoes follow the smell of the human body and fly into the mosquito nets. At this time, the staff can hold mosquitoes in the compartments with mosquito traps. It is sucked away.
M-Toluic Acid manufacturers said that In order to know the living habits and reproduction of mosquitoes, they have cultivated tens of thousands of mosquitoes in the laboratory. Now, with a glance at mosquitoes, small partners can identify the types and ages of mosquitoes. People can't help but praise.
M-Toluic Acid suppliers will introduce to us that when to kill mosquitoes most efficiently
According to the introduction of 3-Methylbenzoic Acid factory, mosquitoes are blood-sucking insects of the double-winged species. There are thousands of species, but there are not many mosquitoes that attract blood. In the lifetime of mosquitoes, there are four life cycles of eggs, larvae (larvae), cockroaches, and adult mosquitoes. All three stages except adult mosquitoes grow in water. Mosquitoes are most active at temperatures between 25 ° C and 30 ° C. At this time, it takes only 7 to 12 days to breed a mosquito. Female mosquitoes produce lumps, each of which can hatch 150 to 200 larvae, after 5 to 7 days of development. For adult mosquitoes. So multiplied, thousands of descendants.
Adult mosquitoes can fly and are not easy to be killed, but the eggs, larvae and cockroaches of mosquitoes develop in the water. Therefore, the best way to control mosquitoes is to mobilize every household to clean up the water and eliminate mosquito breeding grounds, thus reducing adult mosquitoes. Density. If the mosquitoes are feathered, they can fly anywhere. Adult mosquitoes are not as concentrated as larvae, so they are difficult to control.
3-Methylbenzoic Acid manufacturers told us that they are breeding mosquitoes mainly for drug resistance experiments, screening relatively sensitive insecticides to kill mosquitoes more cost-effectively. The experimental results show that mosquitoes in our city have produced high resistance to most insecticides, especially pyrethroid insecticides, deltamethrin, beta-cypermethrin, permethrin, dichlorvos and mutilation. The resistance multiples of Wei and other insecticides were 58.2, 19.2, 11.1, 13.1 and 22.1, respectively. Moreover, in recent years, drug resistance has shown a clear upward trend. The main reason is that pesticides are still the preferred method for killing mosquitoes, flies, cockroaches and other pests, and the dose is increasing. "The more resistant, the more the drug will be used, creating a vicious circle."
Is it related to blood type by mosquitoes?
Some people say that mosquitoes "like" who are related to blood type, because "blood sweetness", experts say, there is no scientific basis. However, it has been confirmed that it is easier to recruit mosquitoes and have the following aspects:
1. Mosquitoes like people with developed sweat glands and high basal metabolic rate, such as infants and pregnant women.
2. Mosquitoes who like to work tired and have a faster breathing rate, that is, those who exhale more carbon dioxide.
3. Fat people are easily bitten by mosquitoes.
4. People wearing dark clothes are easily bitten by mosquitoes.
5. Make-up people are more "welcome" to mosquitoes than people who don't wear makeup, because most cosmetics contain stearic acid (a type of fatty acid), which is also a favorite smell of mosquitoes.
Experts also want to popularize the blood-sucking process of mosquitoes: mosquitoes have a strong sense of smell, and the radius of activity is about 50-100 meters. When humans exhale carbon dioxide and other odors, these odors will spread in the air, and these odors are like the ringing of rice, telling the mosquito that a good meal is in front of you. Mosquitoes twisted and twisted with the smell of human exhalation, then fell on the skin and patiently searched for “breakthroughs”, and finally inserted the “needle tube” directly into the skin for 8 to 10 seconds.
The key to reducing bites
Method 1: Take a bath and use less cosmetics. Take a bath, keep your skin fresh, and wipe off sweat when you sweat. It can reduce the attraction of sweat odor to mosquitoes. Use less cosmetics that mosquitoes like.
Method 2: Wear light-colored clothes for outdoor sports. When you are active in places with more mosquitoes, try to wear light-colored long-sleeved clothes and wear socks at the same time. This will not only reduce mosquito contact, but also reduce the humidity of the human skin, reduce the volatiles on the skin, and reduce the bite. .
Method 3: Proper use of repellent. Repellent is a drug that is applied to the body to drive away mosquitoes. It can be applied to bare skin, such as arms, face, neck, calf, etc. It is usually effective for 4 hours. After this time, it should be reapplied. Also, pay attention to see if you have allergies. The efficacy of the drug is related to the amount of activity and the amount of sweat. If it is outdoors, the duration of the effect may be shortened and it should be applied in time.
It has been found that the most effective mosquito repellent products still contain DEET and mosquito repellent products. Other products are not completely ineffective or have weak effects. The best way to prevent mosquitoes in infants and young children is to use mosquito nets.
How to use mosquito coils and aerosol insecticides? Experts say that when using mosquito-repellent incense, electric mosquito killer, liquid mosquito-repellent incense, or aerosol insecticide to kill mosquitoes, the correct way is to ignite mosquito coils or aerosol cans to spray into the air for 1-2 seconds, then close the doors and windows. Leave, after an hour or two, open the doors and windows to keep it ventilated. At the same time, it is best to close the screens to prevent mosquitoes from entering. In doing so, the insecticidal effect is good and the human body inhales less.
