Spiders are insects that can be seen everywhere in daily life and are of great variety. They use weaving webs to capture other lost insects as food, especially in used houses. No one has a long time to get spider webs everywhere. But for common spiders, we are most annoyed at the web they weave. Some members of the spider family are really poisonous. Don’t look at their small size, but the consequences will be very serious if they bite people.
Spiders are like snakes and will bring fear to humans. The species called " Black Widow " in the large spider family is the very poisonous spider, which is more than 10 times stronger than Rattlesnake .
Recently, when Xiamen Customs was conducting normal supervision of imported car containers, it found that there were black spiders in the container.
According to the normal work flow, the inspection work was stopped and the closed container was immediately disinfected. In the subsequent search, the staff found a "fish that slipped through the net". This black live spider was identified as a spider breed called "Black Widow", which is extremely toxic.
spiders have a special "order" in biological classification, called spider , and black widow spider is a member of the order Spider, the family Spider family, and the genus Koros. The scientific name is the genus Koros. Compared with other spiders, the black widows, it is relatively easy to identify. Its body is relatively large and has a length of between 2-8 cm.
There is a reason why they get the nickname Black Widow. Black Widow male individuals are smaller than females, which is similar to mantis. It seems that many insects with similar sex eaters have this characteristic. The male individuals are small and naturally cannot compete with female individuals. When a female black widow can eat males as food after mating, hence the name Black Widow.
In fact, sexually eating similar species is more common in many insect species, such as mantis and spiders, but not all spiders will eat similar species. Therefore, the name of the Black Widow can be obtained by the species "Black Widow" should not be just because they sexually eating similar species, but naturally have a certain relationship with their toxicity.
Black Widow Spider is a general term for all members of Kou Spider. The members under this rank are indeed not weak, all of them are very poisonous. In the Black Widow's venom, there is neurotoxin , which is similar to some snake venom. If the poisoned person is severely poisoned, it will cause death. Every year, there are cases of being bitten by a black widow spider at home and abroad. The bitten person will suffer severe pain, fatigue and nausea for about 5 minutes. If he cannot receive timely treatment, he may die in a few hours!
"Black Widow" is a very terrifying spider. First of all, because of their toxicity, it is 10 times stronger than the venom of the rattlesnake. Secondly, the "Black Widow" has extremely strong reproductive ability. They only need to mating once in their lives to reproduce. The female "Black Widow" can lay more than 5,000 eggs in their lifetime. It is hard to imagine that such a black widow would be a "army" if she followed the container to quietly enter our country.
What's more, it appears as an invasive alien species. Although the spider like Black Widow is also distributed in my country, mainly in Yunnan and Xinjiang, the number is not very large.
The harm of alien species is extremely great, and there have been many famous cases, such as the proliferation of Asian carp in North America, and it is impossible to catch it or eat it. The proliferation of Australian hares, cats, and fox is also difficult to cure.There are also many invasive alien species in my country, such as Fushou Snail , Canadian yellow flower , etc., and crayfish have been easily taken down by "foodies". Not only is it not overflowing, but it also forms an industry that must be cultivated to provide food for everyone to eat!
Some invasive alien species can be controlled, but insects like Black Widow with extremely strong toxicity are difficult to deal with. First, as an invasive alien species, they rarely have natural enemies and can develop rapidly. What's more, they have particularly strong reproductive ability and are not so dependent on their other half, because they only need to mating once in their lifetime, and they can lay a large number of eggs. More importantly, this spider is too poisonous and is still dangerous to us.
In recent years, some unquarantined animals have been often disguised and packaged and sent to the country through various channels. Some are raised by individuals as pets, while others are completely trying to endanger our ecosystem. Some alien species may also carry diseases as pets. If you accidentally run into the wild, it will be an species invading . These alien species will develop quickly, affecting the development of local species and destroying the ecological environment.
can only say that everyone is responsible for preventing foreign species from invading!
