Since this year, news about biological "invasions" has become more and more frequent. Since April, our country has also seized many "alien species". For example, in April, 38 poisonous ants entered Shandong and were seized in Xiamen. The first seizure of 5 live Echinacea spp., etc., all illustrate that biological invasions are happening all the time. Of course, this includes artificial introduction. Basically, what the customs seizes may be those that were purchased by someone, followed by natural introduction, and then unintentional introduction.

So, let us first remind you that the introduction of alien species will bring about an ecosystem crisis, and in severe cases may even lead to large-scale extinction or disappearance of native species. In recent years, "pet breeding" has become more and more popular, which has led to many species entering our country. This is one of the most fundamental reasons. Next, we will talk about the news that red fire ants have spread to 12 provinces in China, because there is a new trend, this time it is mainly a problem in Guangzhou, Guangdong.

A large number of red imported fire ants appeared along the river in Guangzhou. Of course, the Ministry of Agriculture previously said that red imported fire ants have spread to 12 provinces in China, including Guangdong. At the same time, everyone also knows that red imported fire ants were discovered for the first time in China. The footprints are in Guangdong, so it is not strange for red imported fire ants to appear in Guangdong. The area discovered this time is in Tianhe District, Guangzhou City, and after expert identification, there are a large number of ants appearing near the nearby river, which is "disturbing" Red fire ants are "fearful upon hearing the news", so it arouses everyone's concern.

These red imported fire ants create "ant nests" in these areas, which means that if they are not eliminated, they may expand on a large scale in the future. Now Guangdong is also carrying out the emergence of red imported fire ants. And in the areas where they were found, these red fire ants can easily enter areas such as grassland, field ridges, and woodlands, and form obviously raised sand pile-like anthills. This is when they are making "ant nests". Just remove them gently. With some disturbance, these fire ants will emerge in large numbers.

How terrible are fire ants and what consequences will they bring? Red imported fire ants are a species distributed in South America, but due to trade activities, this species has quickly spread to all parts of the world, including when it was first discovered in my country in 2004, it was limited to Guangdong, but unexpectedly, it has arrived In 2021, "it" has already appeared in 12 provinces in our country. You can imagine how crazy its spread speed is. And in the last 5 yearsDuring the period, the spread of red imported fire ants was very fast, doubling compared with 2016.

Of course, in addition to spreading, the reproductive ability of red imported fire ants is also relatively strong. In 8 to 10 weeks, large-scale offspring of red imported fire ants can be formed. And according to scientific survey data, the number of eggs laid can reach the maximum when food is sufficient. A mature ant nest can reach 240,000 worker ants, so it is too many. And you can see from the "ant nests" in life that the "ant nests" of red imported fire ants are in a "gathering" pattern, including the red imported fire ants discovered this time in Guangzhou, Guangdong, which are very numerous.

If you wait for them to breed offspring, hundreds of thousands or millions of fire ants may appear in one area, and then it will be even more difficult to control them. Nowadays, many provinces in southern my country have been completely occupied by "red imported fire ants", so if it spreads to the northern region, the impact will be greater, and now we can only continue to establish prevention and control mechanisms to curb the spread of red imported fire ants. , the degree of occurrence in most occurrence areas is controlled at a low level.

In addition to the impact of red imported fire ants on the ecosystem, there is another issue that is the impact of red imported fire ants on the human body. Science has confirmed that red imported fire ants are aggressive to humans and have the ability to sting repeatedly. People who are bitten will have red, swollen and itchy skin. If they are attacked by red imported fire ants multiple times, since each attack will release venom from the sac. It releases venom in the environment, so it can easily cause fatal effects on people. In severe cases, death may occur. Everyone should know how terrible it is. It not only affects the ecology, but also has fatal effects on people.

Summary: Whether it is red imported imported fire ants, or the 38 poisonous ants we mentioned above in Shandong, the 5 live Echinacea in Xiamen, etc., it all shows that biological invasion has a huge impact on our country. , and now many people do not have a concept of "biological invasion", so they are still following up on "pet breeding" and purchasing non-native biological populations on a large scale abroad. Fortunately, these two times have been seized. Otherwise, when it enters our country, there will be another "trend" of local species becoming extinct or disappearing.

According to the "Biological Invasion" report released by our country in 2020, more than 660 invasive alien species have been discovered in our country, and 215 invasive alien species have invaded national nature reserves, so it is very scary. , if we continue not to control non-native species, then our country’s native species willThere will be large-scale disappearance, which will also be a good thing that there is no way to do. So everyone should stop introducing foreign species now. Most species are introduced by humans. Natural introduction or unintentional introduction may not have such a large proportion.
