highly venomous spider " black widow " was intercepted by Xiamen Customs. It is more poisonous than rattlesnake and can produce 5,000 eggs in one mating. How serious are the consequences once it enters my country?
When Xiamen Customs was monitoring a batch of imported car containers, it accidentally found a black live spider in the box. After closed sterilization, customs officers finally caught a live spider in the corner of the container. After identification, it was confirmed that the spider was The highly venomous spider "Black Widow" is more than 10 times more poisonous than rattlesnakes and is very dangerous.
"Black Widow" is a common name for it. Male spiders are often eaten, which is why they are called "black widows". Although it is true that some members of the spider family have the habit of eating males after mating, it is still debatable whether the spiders actually eat their "husbands", because this phenomenon rarely occurs in spiders.
The spider family is a ruthless character, and the interspot spider is no exception. Its venom contains a protein neurotoxin that can cause a large release of neurotransmitters. After being bitten, it will cause muscle pain, nausea and heart diaphragm paralysis , and even cause breathing difficulties, , and even more serious death.
In August of this year, a young girl in Shaya County, Xinjiang, Munire Asimati was bitten by a "black widow", and soon after that, she developed abnormal shoulder pain, and the pain gradually spread, and finally her entire back was severe. pain. After
realized that the situation was wrong, the family immediately sent Munige Escimede to the hospital. During the medical treatment, the girl was in a coma and her life was in danger at any time. Fortunately, after targeted treatment, the girl turned the corner.
Due to its high toxicity, the spider has also caused school closures. In 2018, black widows were found in many schools in London, England. In order to ensure the safety of children, 7 local schools were closed, and thousands of students were unable to attend classes.
Did Xiamen Customs reject the "Black Widow" because it was highly poisonous?
not all!
In fact, black widow also has a natural distribution in my country, and it has its presence in Yunnan and Xinjiang.
From the perspective of human beings, black widows are highly toxic and can hurt people, so they can be called "pests", but from the perspective of the ecological chain, black widows specially eat cotton bugs and other pests, which can help farmers control the occurrence of pests, So it is beneficial insect again.
Since my country is also its natural distribution area, and it can also eliminate pests such as cotton worms, why does Xiamen Customs intercept black widows?
This is because the "black widow" intercepted by Xiamen Customs is not a local black widow in my country.
When the same species is blocked by the sea, mountains, lakes, rivers and other factors, so that it cannot carry out reproductive communication for a long time, the two will accumulate different genetic mutations in the process of evolution. , will affect the gene frequency of native species, and it is possible to obtain more powerful species after hybridization.
For example: killer bee , the killer bee is a hybrid of African bees and Brazilian bees. Among them, African bees produce large amounts of honey and are more aggressive, but less toxic; and after they hybridize with Brazilian bees, they form a This species of "killer bee" is very toxic and aggressive. Today, the number of killer bees has exceeded 1 billion. According to incomplete statistics, more than 1,000 people have died from killer bees.
If a foreign black widow crosses with a Chinese black widow and gets a more aggressive spider, then we will be in big trouble.
In addition, although there are black widows in Xinjiang and Yunnan in my country, there are no black widows in other places, so once the black widow enters the eastern or central cities of my country through customs, not to mention that it will hybridize with Xinjiang individuals. simplyThis spider bites a person, it is already a terrible accident.
What's more, a black widow can lay eggs for a lifetime after mating once, and can lay 5,000 eggs. Once this black widow has been mated and laying eggs after coming to my country, it will also threaten the surrounding residents.
Therefore, although there is also a natural distribution in my country, foreign individuals cannot be allowed to enter the country.
In fact, my country has very strict control over alien species. Regardless of whether alien species are naturally distributed in my country, as long as they are not reported and quarantined in accordance with regulations, they cannot enter my country. The purpose of
is not only to prevent from invading , but also to protect the healthy operation of the domestic ecological chain.
