The snail is an invasive alien species, what is the best way to solve it?

In the ditches in the countryside, we can often see snails, if we want to completely eliminate these snails, then we can first find the upstream of the ditch, and then put a few bags of tea withered at the upstream mouth, which will contain some tea saponins.

These tea enzymes.

It will follow the irrigation water to kill the snails along the way. If this method is to be used to eliminate snails in the field, then it is necessary to isolate the cultivated rice fields, because the liquid soaked in tea withering is toxic to many aquatic animals. <>

This is actually a more direct and straightforward method, the general prevention and control of snails mainly includes spiramine, spirolamine ethanolamine salt, followed by tetraacetaldehyde, when using the above agents, you need to mix water in strict accordance with a certain proportion, for example, spiramine needs to be mixed with 30% water, and then use spraying to eliminate those snails in the field. Snails in the field in the general field after one day of exposure to the drug.

They will become dehydrated and will slowly die in the next 3 to 4 days or so. <>

We can also put some herring in the water area with snails, because this kind of herring can actually eat those snails, using this method can effectively reduce the density of snails in the water body, and at the same time can effectively control the number of snails. <>

If there are a large number of snails in a certain area, then we can raise some crayfish in that water, in addition to crayfish, we can also raise some ducks or grass carp, because this kind of animals prefer to eat young snails. <>

This is actually a more traditional method, you can directly pick up snails manually, the disadvantage of this method is that it is time-consuming and laborious, and sometimes a lot of man-hours are wasted, but the effect is not very obvious. However, if there is more free labor at home, then you might as well use this method, and the snails you pick up can be used to make feed for poultry, so that you can also turn waste into treasure.

1. Comprehensive management methods. Pick up manually, or raise chickens, ducks and geese, or use lime or tea withering to prevent and control. 2. Chemical control method of Fushou snail. At present, there are four kinds of medicines officially registered on the Fushou snail.

The best solution is to find the nemesis of the snail, in the countryside the nemesis of the snail is the duck, breeding ducks can not only eliminate the snail, but also provide good farm fertilizer.

Kill Fujura's wart directly and use Fusuro's natural enemies to prey on him and reduce its reproduction rate.

It should be eradicated with chemicals, and suitable agents should be studied according to their growth laws and habits, and then sprayed on a large area for prevention and control, so as to solve the problem from the root.

Because the eggs of the snail carry germs, if you touch it, you may have problems with your body and be easily infected with parasites.

Because it contains a large number of parasites and bacteria, if they are not killed during the cooking process, it can lead to allergies, and it can also cause cerebral palsy.

Because the snail is very dangerous, if you touch the eggs of the snail, it may breed some bacteria in our body, and it may also cause disease.

The snail is native to South America, mainly distributed in the La Plata River basin (Paraguay, Argentina, Brazil, etc.) It was introduced into China as a cash food crop in 1981 and became an invasive species. According to records, in 1980, an Argentine overseas Chinese surnamed Huang brought a box of Fushou snail eggs to Taiwan and began breeding. Then, in 1981, Shaxi Town, Zhongshan, Guangdong Province also began to be introduced, and it spread rapidly throughout the country.

The snail prefers to live in fresh water with fresh water and abundant bait, and many groups inhabit the shallow water area by the pond, and the State Environmental Protection Administration of China has listed the snail as one of the major dangerous agricultural invasive alien species.

Hello lz.

The snail is native to South America and is mainly found in the Río de la Plata River basin (Paraguay, Argentina, Brazil, etc.).

In 1981, it was introduced into China as a cash food crop and became an invasive species.

I have checked and verified the information for you, and it was purchased and introduced from Brazil that year

<> Fushou snail is a modified species. Fushou snail is native to the Amazon River Basin in South America, and its strong reproductive ability has caused serious ecological damage to the Heng people in South China and East China, and has been included in the first batch of invasive alien species in China.

Fushou snail carries a large number of parasites, has become a vector of diseases and parasites, has strong drug resistance, and reproduces quickly, so it is an invasive species.

After large-scale breeding, it competes with surrounding organisms for sunlight, water, and growth space, destroying the growth environment of native species and threatening biodiversity. In addition, the proliferation of snails will lead to eutrophication and deterioration of water quality, and it will also swallow and damage aquatic plants that can purify water, which is very unfavorable to improving the water ecological environment.

During the rice growth period, Fushou snails will eat rice seedlings and seedlings, resulting in fewer seedlings and fewer effective ears, thus affecting grain yield. Fushou snails eat miscellaneous, like to gnaw plant leaves, etc., aquatic crops such as lotus root in some areas are affected by Fushou snail gnawing, stems and leaves are wilted, and the yield reduction rate is more than 50%.

Morphological characteristics of the snail

The Fushou snail has a spiral-shaped snail shell, the color varies with the environment and the age of the snail, it is shiny and has several fine longitudinal lines, and the head and gastropods stick out when crawling. The head has 2 pairs of antennae, the anterior antennae are short, the posterior antennae are long, and the posterior antennae have an eye on each side of the base outside. There is a thick lung suction tube on the left side of the snail, which is thick as a shell, 7 cm high, thin for young shells, and shallow grooves at the suture line of the shell, and the umbilicus is deep and wide.

Shellfish hermaphroditic, allogeneic mating. Oval, 2 mm in diameter, pink to bright red at the beginning of the eggs, the surface of the eggs has an inconspicuous layer of white powder, under the temperature conditions of May and June, after 5 days it becomes gray-white to brown, at which time the eggs have been dissolved into young snails. The eggs are laid at night on the surface of dry objects or plants above the water surface, such as stalks, ditch walls, walls, ridges, weeds, etc., and the newly hatched larvae snails fall into the water and devour plankton.

<> Fushou snail is dioecious and can reach sexual maturity in just 2-3 months after laying eggs. The female and male snails twist and let the male couple together for mating, which usually takes 2 to 5 hours. If there is a touch disturbance during mating, it will stop immediately.

The female snail often lays eggs at night, crawls out of the surface of the water in Xinzheng during spawning, and lays crimson egg masses on the plants and stakes on the pond wall or water surface, and the ovulation time is as long as 1 hour to 2 hours. Glide.
