How to prevent the wasps from stinging the wasps in the summer

Yesterday, the reporter learned from the city's fire department that within the last week, the fire department had removed 27 cells. The fire department reminded the public to wear less yellow and black clothing when going out to play. The wasp is particularly sensitive to these two colors.

According to the statistics of the 119th Command Center, from 8 o'clock on June 2 to 8 o'clock on June 9th, Beijing Fire Department disposed of more than 20 "pick-off cellular" police. Among them, only on June 3, Beijing Firefighting removed nearly 20 horses and honeycombs in an amusement park.

The fire department said that the summer is the active phase of the wasp and the wasp's toxicity is relatively high. Therefore, people are reminded to avoid wearing yellow and black clothes when going out to play, because the wasp is particularly sensitive to these two colors.

The fire department prompts that if you are attacked by a wasp, you must not run wild, you must shrink in place, protect your head and neck, and do not fight back. If injured by a wasp, the wounded person can scrub the wound with vinegar. The stinger that remains on the wound should be singled out in time, and then use the cupping jar to suck out the rest of the venom. It cannot be squeezed to prevent remaining toxins from entering the body.

The wasp, scientific name "vespa", also known as "viper bee" or "wasp." From the order of the Hymenoptera of the Hymenoptera family, the female bee has a powerful long-needle needle. When attacked or unfriendly, it will attack and cause allergic reactions and toxic reactions. Severe cases can cause death.

Wasp's damage performance

Toxicity: The main components of wasp venom are histamine, serotonin, bradykinin, hyaluronidase, etc. The venom is acidic and easily neutralized by alkaline solution. The venom causes hemolysis, hemorrhage, and neurotoxicity. It can damage the heart muscle, renal tubules, and glomeruli. It can damage the proximal renal tubules, and can also cause allergic reactions.

Poisoning performance: The wasp's skin is immediately swollen and painful, even with skin spots and skin necrosis. When the eyes are licked, the pain is intense, tearing, redness and swelling. Corneal ulcers can occur. Systemic symptoms are dizziness, headache, vomiting, abdominal pain, diarrhea, irritability, high blood pressure, etc., the above symptoms usually disappear within hours to days; severe cases may have lethargy, systemic edema, oliguria, coma, hemolysis, myocarditis, hepatitis , acute renal failure and shock. Some people who are allergic to bee venom can present with urticaria, anaphylactic shock and so on.

Hornets' reason

1. Due to the climate warming, especially the increase in the average temperature in winter, the number of wasps in the winter has increased. There are currently about 12-15 million honeycombs in Ankang (an average of about 20,000 in each county).

2. The increase in the area of ​​ecological forest lands and the increase in the number of insect populations provide abundant food resources for the wasps. At the same time, a large area of ​​economic forest such as persimmons, pears, apricots, etc. is provided to facilitate the watering of wasps. Vespa eats honey-originated foods. Shows that Ziyang County, with the highest promotion rate of oilseed rape, is the most seriously affected by the bees

3. The vast majority of human casualties were revenge when they actively attacked the hive; the cosmetics used contained components similar to those of the wasp pheromone; those who consumed alcohol were vulnerable to attack by the wasps.

After being paralyzed by a wasp, preventive first aid measures :

1 Be careful not to disturb the wasp and go out with a hat.

2 The courtyard should always trim the trees and loosen the soil to reduce the chance of the wasp nesting. Avoid planting succulent plants behind the house and reduce the chance for the wasps to enter the house.

3 Do not raise bees near the village.

4 Uncovered sugary foods and drinks should not be placed in empty areas so as not to build up wasps.

5 The chemical synthetic substances and odors contained in cosmetics tend to imitate natural flowers and are easy to recruit bees. Do not drink or use cosmetics before traveling.

6 The wasp is color-blind, and sporadic bees do not have to bother when they fly and harass. When the bee stops on the head and shoulders, it can be shaken off. Do not beat.

7 be attacked by bee colonies, should be wrapped in exposed parts as soon as possible, can be immobile, do not run quickly, not to repeatedly beat.

8 When working in the field, observe the surrounding environment to avoid disturbing the hive. Wear dark long-legged pants protection when working in areas where the wasp is densely populated.

9 In the field investigation, if you meet a soaring wasp hovering around, you are close to its alertness, never wave it or harass it, or observe the wasp very close to it, and leave as soon as possible so that it does not send a message to the bees. attack.

10 Discover the wasps nest near the human activity area. Do not pick up the nest without perfect protective equipment and report it to the fire department. Fieldworkers should carry emergency medicines (such as snake medicine, astemizole, etc.) with them.
