What's going on? In recent times, there have been live animals from abroad entering china by mail, fortunately intercepted by China's customs, avoiding the risk of alien species invading our country, 19 live fire salamanders from abroad, 50 giant ants from Southeast Asia, 38 highly toxic ants of unknown origin.
Recently, Qingdao Customs seized more than 7,000 live black-bellied fruit flies in a parcel, which is the largest number of live animals seized by Qingdao Customs, which is from the United States and the name is declared as "clothes". Shanghai Customs intercepted a batch of live snails, the name of the mail read "toy", but it was actually "forest snails", the number of which was as high as 154.
This shows that with the convenience of human transportation, the frequency of foreign animals entering China is increasing, and a little attention will have an impact on China's ecological environment, causing widespread concern.
Nanjing Customs seized 6 larger Japanese shovels
In the past two days, when Nanjing Customs conducted an X-ray inspection of an inbound parcel, it showed an abnormal picture, suspected of being a trace of insect activity, and after opening, it was found that it was a Japanese shovel live body (Dorcus hopei binodulosus), a total of 6, 4 females and 2 males, which were loaded into 6 glass bottles containing wet wood chips and nutrients.
From the photos, this batch of Japanese spade beetle live bodies is slightly larger than the ordinary, very strong, about 8 centimeters in length, probably carefully selected before mailing. If the Japanese spade armor enters the wild in China and becomes an invasive object, it is only afraid that it will damage the local ecological environment and disrupt the food chain.
Many Chinese people are very angry about this incident, have left messages, some netizens said, the recipient is not clear in the mind, china's red fire ant lesson is not enough? Some netizens said that China must strictly prevent the invasion of alien species, and some netizens said that it is really strange, why bring it into the country?
Why did the Japanese spade beetle live body enter China?
Let's first briefly understand, the Japanese spade armor is native to Japan, relative to China's Chinese spade armor, the body size is significantly larger, the body length can reach more than 8 cm, the Japanese spade armor is very aggressive, especially the male, the upper jaw is developed, shaped like antlers, the force is infinite, when they meet in a narrow road, there will be a fight.
Since ancient times, china likes to play aggressive small animals, especially crickets, fighting crickets once prevailed throughout China, has a history of thousands of years, has become a part of Chinese culture, and the Japanese spade armor is particularly aggressive, perhaps some people regard the Japanese spade armor as an entertainment, like the fighting crickets, resulting in the live entry of Japanese shovel armor into our country.
If it is only for personal entertainment, it is necessary to mail some species from abroad that should not belong to our country, then this behavior is also too selfish, to know that species invasion can cause very serious consequences, red fire ants are the lessons of the car, of course, the Japanese spade as entertainment, is still just a personal speculation.
Chinese spade nails
China also has a local Chinese spade armor, Huada spade beetle insect genus, spade nail family, body length of 40 ~ 70 mm, slightly smaller than the Japanese spade nail, the appearance is almost the same, the Chinese spade armor is covered with black armor, inhabiting the southern altitude of 200 ~ 2000 meters in the mountainous area, the Chinese spade nail life cycle is divided into 4 stages, eggs, larvae, pupae, adults.
Chinese spade adult worms feed liquid, honey, and larvae inhabit decaying wood, mainly scavenger, every Year from May to September, pupae grow into adults, often appear on sap trees, because it likes to feed on sap, Chinese spade adult worms, during the day, A likes to hide in the tree hole, night only began to come out of the activity, especially sensitive to wind and sunlight.
Every year from May to September, also the breeding season of the Chinese shovel, the female Chinese shovel lays eggs in the decaying wood, and when the temperature is between 20 and 25 ° C, the eggs will spawn larvae. Because the male Chinese spade has antler-like horns in front of it, it looks imposing, so the Chinese spade armor is loved by people and is regarded as a pet. In the same way, the Japanese Japanese spade is also loved by people.
What is the biggest difference between the Chinese spade armor and the Japanese spade armor? From the comparison chart, the head of the male Chinese shovel in China looks larger, the head horn is larger, and the momentum is stronger, but the overall size of the Japanese spade armor is larger.
What is the current status of species invasions in China?
Species invasion is divided into 4 stages, invasion stage, settlement stage, adaptation stage, and diffusion stage, China has conducted a survey of 52 invasive alien species with major hazards, and found that more than 60% of the species are caused by human causes, such as transportation brought in, international agricultural trade, such as poisonous wheat is with the wheat trade into China.
In China, 31 provinces have the phenomenon of invasive alien species, and among the 2862 counties in the country, 54.09% of the counties with invasive alien species. Invasive species have a great impact on native species, with potato beetles causing a 60% reduction in potato production, American Brazilian tortoises posing a great threat to the survival of native turtles, and the most annoying red fire ants.
In short, the status quo of species invasion in China is not optimistic, and has caused great economic losses, so we must strictly prevent the invasion of alien species and prevent any alien species from entering our country, which also requires the cooperation of every Chinese, and do not mail live animals and plants from abroad.
