Poisonous ants, red fire ants, euphorbia worms, and a batch of "widow spiders", what is the situation? Since 2021, china has more and more news about the entry of "alien species" into our country, is this not scientific? Whether the information age is too advanced, or whether some people are specifically questioning the ability to be seized, alien species we have repeatedly explained, this is not only a large impact on the local biological population, but also a devastating impact on the local ecosystem.
You should know about the red fire ant incident. Red fire ants spread in many provinces in china, have not been completely cleaned up, and now it is poisonous ants, euphorbia worms, widow spiders into the entry, which is nothing more than to bring greater trouble to our country, let's take a look at the situation this time.
<h1 class="pgc-h-arrow-right" data-track="11" > Nantong Customs intercepted the highly toxic "widow spider"</h1>
According to the scientific report, the seizure of the highly toxic "widow spider" is not the first time in 2021, it is already the second time that Nantong Customs intercepted a highly toxic spider on an international voyage ship this year, which is a ship of about 30 years old, which was found to be in the presence of spider webs during the inspection of the deck, manhole, top pier and cabin, and finally after in-depth investigation, 17 live spiders were found, and there were a large number of fresh egg sacs.
Later, after expert identification, these 17 live spiders turned out to be "highly toxic" brown widow spiders, of course, it is not yet known how to enter this ship, follow-up investigations may be carried out, if it is intentional to introduce "foreign species", it may bring inconvenience to themselves, and when examining spiders, spider egg sacs hatch hundreds of small spiders, it is conceivable that once it flows into our country, it will inevitably have a great impact.
According to experts, the toxicity of these spiders is very strong, there is a strong neurotoxin in the venom, once introduced and multiplied, this impact on the ecosystem and humans will be huge, so the later also carried out pest treatment, simply found this time.
<h1 class="pgc-h-arrow-right" data-track="11" how toxic are widow spiders >? </h1>
Widow spider is one of the world-famous poisonous spiders, and the spider has been bitten internationally, causing injury to humans and animals, causing death reports, so it is a very dangerous species, mainly distributed in the tropics, and is fed on a variety of insects, if bitten by the organism, local pain or tenderness, severe pain will be after being bitten, about 5 minutes can quickly spread to the abdomen, thighs, waist and other places, so it is very frightening.
Of course, different species of widow spiders are also stronger, generally brown "widow spiders" if they bite the animal, in severe cases can die within a few hours, that is to say, this is a deadly species, so if you bite people, it will inevitably be threatened by life. At the same time, you should also know that the population of the Latrodectus geometricus is very large, very close to the close relatives of the black widow spider, and everyone can understand how much the impact is from the toxicity of the black widow spider.
The population of the black widow spider in recent years, with the expansion of the scope of human activities, has brought it to many areas, so people and animals have been bitten and killed by the black widow spider, including China has also appeared, so strict control of the "highly toxic" biological population into our country is the most critical, it is obvious that this time can be seized on the ship, must be related to the walking path of the ship.
We also said that this is not the first time, the last time 21 live spiders and a large number of fresh spider egg sacs were found, it was also a highly toxic brown "widow spider", that ship had been docked in the Solomon Islands for a long time to load logs, so whether this is the reason for this time remains to be investigated, and there is no explanation for the time being.

Ecosystem is formed after long-term evolution, and after the formation of a stable ecosystem, the benefits are also very much, but with the increase of invasive alien species, as long as it enters a stable ecosystem, it will lead to regional species extinction or environmental destruction, which is why it is necessary to strictly prohibit the population of alien organisms, and China is now also a country with more global biological invasions, according to the data, more than 660 invasive alien species have been found. Of these, 71 have been listed as ecologically threatening or potential threats.
And in this, there are also deliberate introductions, mainly because there are many people who carry out "pet breeding", initially like a creature to buy from abroad, and then breed it, and then release it if they don't like it. So these alien species enter the wild and continue to reproduce, large-scale destruction, leading to the collapse of their own ecosystems.
This is intentional introduction, unintentional introduction is the introduction of the situation that they do not know, mainly through the transport of goods, etc., and there is natural introduction, this way is mainly through migration, the automatic introduction of biological populations and so on.
These three introduction methods, in addition to the natural introduction can not be controlled, the other two can be controlled, so the seizure of many extraterrestrial species is also related to the other two ways. Here is a reminder, in the future, when everyone raises pets, see more about the impact of extraterrestrial species, it is too difficult to maintain the ecological environment, and you should not bring damage.
