Recently, some netizens said that dragon width appeared in Chengdu and released related videos. It can be seen in the video that white noodles are swimming in the water.

It is understood that dragon width belongs to foreign invasive species and was first seen in Guinea, and it is rare in China. Is it really dragon bug in the video? How should we protect it?

Is it a dragon width?

The physical sampling confirmation is required, and the ironworm is not ruled out

Once the videos of suspected dragon nematodes were released, it received much attention. Many netizens are worried that this is the invasion of species, so many people leave a message under the video: "Report quickly!" And the publisher of the video said: "It's already reported," shaking. "

Is it a real dragon bug? Red Star reporter contacted Zhao Li, the director of the Insects of Insects and the curator of the Chengdu Huaxi Insect Museum. "I have watched that video. I guess it is a parasitic nematode in the praying mantis or straight winged insects, and I have entered the water body." Zhao Li told reporters that at present, the praying mantis has just matured, and the parasitic nematodes in the praying mantis have also entered the mature stage. They will release some chemicals that make the praying mantis feel thirsty and take the initiative to find water. Once the praying mantis comes into contact with the water body, they will get out of the praying mantis and enter the water to prepare for breeding.

Needles are one of the largest doors in the animal world. At present, there are nearly 30,000 kinds of nematode animals, and there are still a large number of them.

Therefore, in Zhao Li's opinion, there are many types of such groups. It is difficult to confirm the types and sources by videos. It is necessary to do further investigation. At least it must be collected to the entity for identification to confirm. "Parasites in mantis or straight winged insects, there are the colors and shapes in the video." Zhao Li added that most iron bugs are dark brown, but it does not rule out that individual body color is mutated into white. Belief is a common phenomenon in the animal world.

How to protect it?

Do not drink stream water, maybe the ovary or larvae of wiring bugs

It is reported that patients with dragon width disease will experience symptoms such as fever, nausea, dual limb pain, rash, blisters, ulcers, etc., and a few involve the central nervous system can cause paraplegia. The disease has no special effects at present, and removing insects is the only reliable method at present. In addition, the corresponding drugs can be given to relieve symptoms or symptomatic treatment.

How should we protect it? Zhao Li suggested that generally do not drink water in the natural environment, nematodes generally enter the human body through drinking water. There are no problems such as tap water, such as tap water. At the same time, don't drink it directly. In the water bodies in the natural environment, the eggs or larvae of wiring insects may be difficult to find.

In addition, Red Star journalists have learned that the Sichuan Provincial Center for Disease Control and Prevention and Chengdu Centers for Disease Control and Prevention have already mastered relevant information and have reported the information to the superior department.

What is a dragon width?

Dragon nematodes, threadeds, and dragon threads, parasitic in the deep nematodes of mammalian body, were first seen in Guinea, so they are commonly known as "Guinea". Dragon nematodes are more common in tropical and subtropical. The most common is the paracunculusmedinensis, which can parasitize the human body. Women's females move from the deep part of the host to the foot of the feet or the back of the neck to form blisters and ulcers. Whenever the affected part is immersed in the water, the worm head extends outside, releases the larvae, and the worm head shrinks back to the skin. The larvae develops mature after swallowing the sword water flea. Drinking water from humans or animals will be infected, causing dragon width disease.
