Recently, Ms. Lu of Zhengzhou, Henan Province, reported through the media that she rented a house through an intermediary in March, who knew that in July, her body began to be red and swollen, and her arms and backs were full of pimples. At first, Ms. Lu felt that it was a mosquito bite, and she didn't care too much, after all, there were many mosquitoes in July and August.
So Ms. Lu bought flower dew, who knew that the knots would not go on. Ms. Lu began to pay attention to whether there were any other small bugs in the room, and eventually found a lot of small ants on the sheets on the ground. It was these small ants that bit Ms. Lu all over her body. The housing agent said that the ants may have appeared due to heavy rain and humid weather, after all, zhengzhou was always raining during that time.

It's not an ant, it's a bug called a swollen-legged bee. Although it looks more like an ant, it is actually an extracorporeal parasitic wasp. The full name of the swollen-legged bee is Guan's swollen-legged bee, this bug is very small, the female bee body length of 3mm ~ 4mm, the male bee body length of 2-3mm, do not look carefully is really not easy to find them. They are divided into two types, winged and wingless, of which most of the male peaks are winged.
This kind of bee breeding speed is relatively fast, basically can occur 5 generations a year, each time the swollen leg bee can lay eggs from several to dozens of eggs, a female bee can lay 29 to 290 eggs in a lifetime. And their crawling speed is not slow, female bees can crawl about 0.5 meters per minute.

The distribution of the swollen-legged bee is relatively extensive, and it has been found in China for a long time, but it was around 2000 that people really noticed it. Some experts have found that it has a magical ability to prevent and control the celestial cow. Tianniu we all know that when we were young, everyone did not run away from the wild to catch Tianniu to play. But they are a pest, and after mating, adult celestial bulls will bite open the epidermis of trees and place eggs inside the trunk.
When the larvae hatch, they will naturally burrow into the trunk and erode the xylem and roots of the base of the tree, so that the tree naturally cannot grow well, and gradually begins to die or even be hollowed out. Coupled with their strong fertility, fast reproduction rate and high survival rate, the Tianniu has become one of the pests that people have headaches.
In order to deal with it, people have adopted many methods, but it is difficult to work, even if it is external spraying pesticides, it is difficult to eliminate it, and it is time-consuming and laborious to dig it up by hand. Until people started introducing swollen-legged bees to deal with the Celestial Bull. As we said earlier, the swollen-legged bee is an in vitro parasite, and its main parasitic object is the dry moth pest of the tianniu.
The swollen-legged bee will first find the host through the worm path, and then inject the host with bee venom through the tail spine of the tail, and when the parasite is paralyzed, the host body fluid is sucked and the host dies. A female bee can parasitize up to 5 Qingyang Tianniu larvae in her lifetime, and can lay up to 76 eggs on Tianniu larvae at a time.
And one of the advantages of this bee is that it doesn't flood. When the tianniu on the tree is destroyed, the swollen-legged bee can not find a suitable host, and soon it will die on its own, which will not cause harm to the environment, and also reduce the use of insecticidal pesticides, reduce environmental pollution, and is the first choice for preventing tianniu in many places.
<h1 class="pgc-h-arrow-right" data-track="16" > the introduction of swollen-legged bees</h1>
In 2016, Zhengzhou introduced 1 million Guan's swollen leg bees, and in 2018, Zhengzhou introduced 300,000 Guan's swollen leg bees. Sanitation workers attached test tubes containing 100 swollen-legged bees to the trunk of the tree and then released them, and the little bugs naturally went to the pests such as the Tianniu.
With the success of the insect control method, people tasted the sweetness, and 7.58 million beneficial insects were introduced to prevent pests. It is mainly used to deal with aphids, red spiders and celestial cattle. Many cities in China have introduced swollen-legged bees to prevent and control tianniu.

Although the swollen-legged bees are beneficial insects, they are not comfortable being bitten by them, and the pain and itch are all red bumps. This kind of bee mainly enters our home with the wood of the furniture, and if the wood is not well removed, in the summer, the swollen-legged bee will crawl out of the wood, move on the ceiling, and fall on the person. This is also the reason why swollen leg bees always appear in bed.
If there are swollen leg bees in the house, you can buy some insecticidal supplies to eliminate them, but one time may not be enough, generally more than a few times, basically every 2 weeks, after two to three times it is almost the same. We also have to check our own grain, they like to parasitize in the grain, if found, they will deal with it immediately.
Do not scratch the itch hard after being bitten by a swollen leg bee, so as not to scratch the skin and cause infection. We can wash it with soapy water first, generally in a few days it will be fine, there is no harm to the body. If you really feel unwell, you can also go to the hospital to see, after all, some people may be allergic and prone to accidents.
The method of treating insects with insects is naturally good, there is no harm to nature, and it can effectively treat insect pests, but it is still necessary to remind everyone and not to go near them, after all, they bite people is also very uncomfortable. If we find these bugs on our bodies, don't shoot them hard and blow them away gently.
