In recent years, there has been more and more news about the entry of alien species into the mainland, whether it is an attempt or an unintentional introduction, and large-scale alien species are entering the continent anyway.
According to the statistics of mainland alien species, more than 600 alien species have invaded China. Of course, this contains many people "intentionally introduced" exotic species, mainly with the rise of the "pet tide", many people like to raise foreign pets, and finally when they are not raised, they are placed in the wild. This leads to large-scale alien species.
No, according to the Rong Media Center in Siyang County, Suqian, Jiangsu Province, local fishermen found a "turtle (Chinese turtle)". Fishermen say the "turtle" can reach a length of 60 centimeters and weigh about 16 pounds. Fishermen thought it was a wild turtle and released it.
But later it was discovered that this could be a harmful alien species, the Florida turtle. If you look at the root, it may also be farmed. Therefore, after the catch, it may be further announced.
Therefore, alien species in the absence of natural enemies, may have a very large ecological impact.
In 2021, the mainland customs intercepted 65,100 species of quarantine pests, effectively preventing the introduction of major animal and plant epidemic diseases such as African swine fever, red fire ants, and highly pathogenic avian influenza, and returning and destroying 584 batches of unqualified agricultural products. So, customs officers are really working too hard. No, the continent has intercepted alien species, and it is a very terrible species.
From abroad! The highly poisonous spider was seized by the Customs of Putian, Fujian Province
According to the report, the Putian Customs in Fujian Province was found this time when the imported container logs were inspected. So, it's logs from outside the country. Of course, from this situation, the high probability is not deliberately introduced, but inadvertently intruded in the course of commercial activities, and the specific situation may need to be investigated to know.
But the highly poisonous spider found this time is indeed terrifying. What kind of spider is it? That is the living spider inter-spider spider, commonly known as the black widow. At the same time, four egg sacs were intercepted.
What species is the Interbranched Spider? The mesopoda is a species of spider belonging to the genus Theridiidae (Theridiidae) of the genus Latrodectus Walckenaer (1805).
The appearance of this spider is frightening, and its appearance is a little strange. The jaw lobes , lower lip , and thorax are all dark brown , and the thorax is densely covered with dark brown fine hairs , and the leading edge is nearly straight , equivalent to a species of mixed colors. The female spider body length of this species is generally 11.40 mm, and the length of the male spider is generally 4.20 mm, so it belongs to the medium-sized category of highly venomous spiders.
This spider is generally active in wild slopes, farmland, orchards, so it is very easy to contact humans. Because it is a highly toxic species, when preying on food, it is generally "poisoned first and then eaten". After the spider webs of their own layout, especially for slightly larger insects, they are first bound with silk, injected with venom, and then sucked.
And it is also very clever, if it is frightened or encounters an enemy, instead of being slaughtered by other spiders, it quickly flees to the edge of the web or falls off the web, pretending to die, and then after the crisis is lifted, it will return to the spider's web.
Therefore, the inter-spotted spider is also a relatively "smart" species in the biological world, of course, its reproductive ability is also very strong, and this customs interception is also relatively timely.
You should know that although only 4 egg sacs were found this time, a single egg sac can contain 400-900 eggs, from which the eggs hatch, they can mature after three months, and live up to 3 years.
See? If 4 egg sacs can produce 3600 highly poisonous spiders according to the highest survival rate, then reproduction is more frightening. Let's see how poisonous this creature really is.
How poisonous are highly poisonous spiders?
Since it can be called "highly toxic", it must be a more toxic species, otherwise it will not be called "black widow". Its own habits are also frightening.
It is understood that because the female of this spider will bite the male mate after mating, the folk also directly say that it is the "black widow", so when encountered in the wild, we must be vigilant. Although this creature is an exotic species, it is also distributed on the mainland, and we can only minimize this species.
The species has indeed been found in Xinjiang on the mainland, and there have also been cases of "death". So how poisonous is it?
According to the research situation, the venom of the inter-spotted spider contains a protein neurotoxin that can act on the synapses of vertebrates, causing a large number of neurotransmitters to be released, and people have a pinprick sensation after being bitten.
After being bitten, the wound area will show pallor, redness and other phenomena, because the toxicity is relatively strong, so local pain or tenderness. At the same time, as the toxicity spreads further, it will also show numbness and tingling sensation in the feet, as well as a characteristic heel burning sensation.
In severe cases, blood pressure rises first and then decreases, showing a state of shock, and there are cases of breathing difficulties and even death. So serious? It's that serious indeed. The mesopodium is one of the 10 most venomous species in the world, 15 times more venomous than rattlesnake venom.
Therefore, after being bitten by a highly poisonous spider, we must deal with it quickly, and we must not underestimate this spider. And we also said that this spider has also had cases of death, which is indeed true, and it happened on the mainland.
In 2007, a 15-year-old elementary school student was bitten by a poisonous spider and poisoned the next day after being rescued to death. After identification, the scientific name of this poisonous spider is the inter-spotted spider. So, it's this poisonous spider, and that's the general situation.
What if you are bitten by the "Black Widow", the "Black Widow"?
Of course, first of all, we need to strengthen our own protection and reduce the black widow from biting herself. The best thing to do is to spray insecticides on the infested area so that it cannot survive.
However, as we said above, this creature has strong reproductive ability, and it is impossible to prevent it for time, so what if it is bitten? After searching for information, everyone can refer to it.
First, if you are bitten, whether it is a hand or a foot. The wound is ligated with a rope strap, and then, the wound is first washed with supersaturated potassium permanganate solution, and if these things are not available, go directly to the hospital for cleaning.
Second, if you are bitten, you can use your mouth to repeatedly suck the wound, spit it out, and suck out the poison, which is the same as the treatment method after being bitten by a snake in many rural areas. However, the most important thing is not to suck into the mouth and swallow into your stomach, then the harm is even greater.
The above two methods are referred to below. The safest way is to go to the hospital for treatment, after all, it is a highly toxic species. So, don't underestimate spiders, which are "lethal" creatures. I also hope that in the future, after everyone sees this alien species, they will report it and deal with it, and they will not let it spread, so that they will be more threatening to themselves.
