Behind Fushouluo, behind the auspicious name, it is a serious threat to ecological safety, agricultural production safety and public health and safety.

Data show that Fushouluo was originally produced in South America and was introduced to my country in the 1980s as special economic animals to promote breeding in many areas. However Soon spread from farmland to natural wetlands. Its eats a lot and likes to eat rice and aquatic plants, leading to reducing food production, destroying the growth of vegetables and aquatic plants, and deteriorating the ecological environment. In 2003, it was included in the first batch of 16 most harmful foreign species that invaded my country.

Over the years, people have not stopped with its "fighting".

The dangerous pink "bubble" can be severely reduced to reduce the production of rice fields by 50%

In mid -May of this year, Zhang Gongsheng, a group of villagers in the three groups of villagers in the three groups of villagers in Guanbaqiao Town, Xian'an District, Xianning City, found that the seedlings were delayed when they irrigated the middle of the rice fields. Agricultural experts in the district and town go to the scene to identify: Many pink unknown species are adsorbed on the seedlings, which are Fushou snail eggs.

Fushouluo mainly endangers crops such as rice, lotus root and vegetables near the waters, and is a veritable crop killer. After investigation, the Fushou snails of the 300 acres of fields in the three groups of Ferry Village have been explosive. The field rice is lacking in leaf seedlings and grows slowly. What will happen to it? Related statistics show that Fushou snails generally cause an average of 5%to 10%of the paddy fields per mu, and the damaged paddy field reduction can reach 30%to 50%.

Danger is not only in rice fields. Since August, when many citizens have played in the Wuhan Donghu Scenic Area, Yingcheng Old Guanhu Wetland Park, etc., they also found that the water coast, naked stones and the stems of the aquatic plants have the Fushou snail eggs on the stems of the stems of the aquatic plant. "Looking like a pink bubble from a distance, it can be seen that it is a insect egg." A witness citizen introduced.

Fushouluo likes to survive in fresh water with fresh water quality. In recent factors such as suitable temperature and good living environment have led to the breeding of Fushou snails in the waters. "Don't look at it small, a snail egg can hatch 200 to 1,000 young snails." The person in charge of Lao Guanhu Wetland Park introduced that the strong reproduction ability of Fushou snails will compete with local snails, fish or other species for food and inhabitation Land resources have caused a large number of local species to decline or even disappear, severely damaging farmland and wetland ecosystems. And the large amount of feces they produce will also cause pollution to the water body.

It is urgent to eliminate Fushou snails and protect ecology.

People pick up, medicine, and ducks and geese to start the "Destroyer War"

In the past few days, many garden workers are searching and governance to the Fushou snail eggs on the water surface of the river. Yang Kai, staff member of the Municipal Garden Greening Center, introduced that in May this year, the Fushou snail egg block was found on the Jingxiang River's water body plants, and the city garden greening center launched the first round of governance in a timely manner. At the beginning of September, after the weather turned cold, due to the growth of the Fushou snail eggs, the garden greening center immediately carried out the second round of governance.

Faced with such a huge "uninvited guest", the amount of artificial egg picking and picking snails is huge. Is there a more labor -saving method?

"Gap …… ... quack ..." On September 8th, the "double water and double green" rice demonstration base in Xingguang Village, Xingguang Village, Xingshou City, Shishou City.

Grave and duck co -operating is one of the local traditional farming methods. Today, in addition to eating bugs in rice fields, ducks have an additional task -destroy snails. The villagers use the habit of ducks to eat young snails to keep ducks in the rice fields according to the density of about 15 per mu, which can not only eliminate Fushou snails and pests, but also fertilize fields and inhibit the breeding of weeds. In addition to biological control, physical control and chemical prevention methods are also essential. According to the breeding characteristics of Fushouluo, the villagers are also inserted in the field in an orderly manner to seduce Fushou snails to reproduce on the water to reduce the harm to the water body. Connecting the interception network at each drainage port to prevent the spread of snails and the infringement of food. The remaining position is obvious or difficult to deal with, and then eliminate it by manually picking up the snail.

Large -scale and short -term low -time insect density, using drones to spray an appropriate amount of snail pesticides, the advantage is unparalleled. On May 31, the village of Daqiao Town, Guanbuqiao, Xian'an District, over the paddy fields, drones circling dancing, and continuously spraying yellow snails. Under the coordination of the town agricultural technical service center, the agricultural machine hand -operated drone was operated to chemically control the Fushou snail by controlling the rule of the rule. From 9 am to work at 9 am to 4pm, the potion was finally sprayed. Nowadays, rice fields have resumed another vitality.

Ready to fight "lasting war" monitoring, popularization, and census indispensable

In the past two years, the topics of Fushouluo, crocodile crumper, and a yellow flower in Canada have frequently rushed to the Internet hot search. Crayfish has also been a foreign species, and now it has developed hundreds of billions of levels of wealthy industries. Can the Fushou snail become a treasure?

Chu Shihai, deputy director of the weeds and foreign invasion of the Biological Research Office of Hubei Academy of Agricultural Sciences, said that because Fushou snails carry more parasites, it is recommended that citizens not to eat. When the Fushou snails that are not cooked with Guangzhou tube roundworm can cause human infection and cause circular width disease in Guangzhou. The incubation period of this disease is mostly 1 to 2 weeks, and the nematode may be drilled to the brain to destroy the nervous system. He particularly reminded that some illegal vendors may mix it into field snails and conch, and citizens who like to "string" on the street must be careful. At present, the recycled Fushou snails are conventional means. The resource use of Fushou snails is mainly concentrated in the feed, and the high temperature treatment of Fushou snails is treated as shrimp, money turtles, cattle, ducks and other feeds after crushing, and reduced industrial bait. The reporter inquired that the research team of South China Agricultural University explored the establishment of a technical method for extracting lecithin from the Fushou snail, or provided new ideas and new ways for the development and utilization of Fushou snails. It turns out that early discovery and early treatment are the most economical and effective methods for preventing and controlling foreign creatures.

At present, the Provincial Department of Agriculture and Rural Affairs has issued the "Further Strengthening the Prevention and Control Work Plan for Foreign Species" with the Seventh Department Bureau of the Provincial Department of Finance and other seven departments. Control coordination mechanism. In response to major foreign invasion species in different periods and regions in the province, the "one strategy" strategy is continuously implemented in the implementation of water peanut biological prevention and control, a bark of Canadian Huanghua people, the comprehensive prevention and control of Fushouluo, and the industrialization of Keshi's chewed shrimp. The census census in the province's agricultural agricultural invasion is also underway.

At the beginning of September, the Provincial Agricultural and Rural Department held a special training meeting for the prevention and control of Fushou snail prevention and control in Shishou City to improve the grassroots prevention and control capacity and public awareness of public prevention and control. In the future, our province will also give full play to the excellent mechanism of joint defense control and group defense and group control, and explore a group of social public "census" through public survey apps and public release census categories.

The relevant person in charge of the Provincial Agricultural and Rural Department stated that it will further strengthen measures, adhere to the source control, comprehensive governance, coordinated cooperation, and public participation, and improve the management level of foreign invasion species. Strengthen technical research and development, monitoring and early warning, governance and restoration, improve laws and regulations, build a full chain prevention and control system for foreign invasion species, and make positive contributions to building important ecological security barriers in the middle and lower reaches of the Yangtze River, ensuring the safety, ecological safety and food production safety of the Yangtze River Basin Essence
