Cangzhou: The "annihilation war" of the American white moth is launched

A few days ago, a drone full of drugs took off on the roadside of Chenzui Township, Qingxian, Cangzhou. It passed the treetops at a low altitude and sprayed the medicinal solution evenly in the woods. The "battle" of the second -generation American white moth in Cangzhou has begun.

American white moths focus on this year

"The strong survivability of the pests such as the American white moth is stunning: the high temperature of 40 ° C is not dead, and the low temperature of minus 16 ° C is not dead. It can develop normally. "Hou Junming, director of the Forestry Harmful Biological Prevention and Quarantine Station of Cangzhou Natural Resources and Planning Bureau, introduced that if the conditions are appropriate, as long as a female moth is allowed, 800 to 2000 capsules can be spawned at a time. If it does not control, the population can reach up to tens of millions a year. High adaptability and the outbreak of American white moths last year in North China caused serious harm to forestry production, and laid a hidden danger for severe pests this year.

In order to accurately grasp the occurrence of American white moths, Cangzhou City is fully operated by the US white moth monitoring system and implements the reporting system on the prevention and control work day. After testing, the city's overall American white moth this year was heavier than in previous years.

"This year, the city's white moths have an area of ​​about 600,000 acres, involving 5487 villages in 183 townships (towns) in 18 counties (cities, districts)." The three generations of "the" three generations of "prevention and control, seized the key period of the American white moth to investigate the defense, and adopted a variety of prevention and control methods such as lighting and killing, artificially cutting, ground spraying, helicopter flying, and drone flight defense.

The prevention and treatment of white moths cannot be relaxed

"From the current situation, due to various factors such as high temperature and high humidity weather, the tasks they face this year are still very arduous, and the prevention and treatment of American white moth cannot be relaxed." Hou Junming said.

The reporter interviewed on the spot on some roads that were deeply trapped by American white moths and confirmed this. On some poplars, the leaves are burnt, which is the evil of American white moths. Some American white moth larvae have grown into old -fashioned larvae after molting many times. On the roadside of the road, some aging American white moth larvae crawled in groups.

It is understood that from late July to early August, the second -generation American white moth is mainly in a period of harm. The third -generation larvae began in late August, and the harm will continue until October. In order to accurately grasp the occurrence of the city's white moth in the city, Cangzhou Natural Resources and Planning Bureau urged all localities to carry out prevention and control work in a timely manner, and set up three supervision teams to carry out uninterrupted supervision and inspection of the city's prevention and control work.

Supervisory found that in accordance with the unified deployment of the city and seizing the opportunity to actively carry out the control of the prevention and control operation, American white moths are harmful. In areas with lagging prevention and control and low operating quality, American white moths have a lot of weight. On both sides of the Cangzhou West Expressway, the Beijing -Shanghai Expressway Hejiayuan to the canal section, the Cangzhou service area to the south rivers of the Cangzhou service area from the Beijing -Shanghai high speed, the harm of American white moths is more serious. After the problems were discovered, the Municipal Natural Resources and Planning Bureau made a judgment of the problems that arise, and formulated an emergency response plan to timely urge each county (city, district) to carry out control.

At present, the counties (cities, districts) have taken corresponding prevention and control measures. Qingxian, Cangxian, Xinhua District, Botou, Hejian, Singing, Xianxian, Huanghua, Yanshan, etc. , Grand Canal's landscape belt, seedling base and other key areas have been controlled by air spray prevention and control. Mengcun, Haixing, Su Ning, Dongguang, Nanpi, Nanga Port and other places use pesticide spray cars, smoke machines, small sprayers, vehicle high -voltage spray guns and other equipment to carry out ground spray prevention and control.

Up to now, Cangzhou has completed a total of 1.321 million mu of prevention and control, of which 1.067 million mu of air control and 254,000 mu of ground prevention and control are underway.

Weaving the prevention and control network for the participation of the whole people

"Because the American white moths are mixed, the common broad -leaved tree species are basically the food of the American white moth." Hou Junming said that according to the monitoring of the prevalence of the forestry prevention and control personnel in various counties (cities, districts), the reflection of the citizens in Cangzhou The occurrence of moths is more common, and it is particularly harmful to tree species such as poplars, Fa Tong, and white wax.

Yu Kodong, deputy director of Cangzhou City Natural Resources and Planning Bureau, said that they will continue to make efforts and take multiple measures to strengthen the prevention and control of pests and insect pests such as American white moths, and organize forestry harmful biological prevention and control team to go to counties (cities, districts) on site supervision. The second -generation American white moths and other diseases and insect pest control and third -generation prevention and control preparation. Research and judge in advance, formulate the third -generation American white moth and other diseases and insect pests prevention and control solutions, add prevention and control funds, and earn early reserve to prevent pharmaceutical medicines. At the same time, strengthen census monitoring, accurately predict the dynamics of insect sentiment, and timely issue insect sentimental warning. According to the monitoring, supervise and guide comprehensive measures such as aircraft spraying, drone, ground medicine, artificial physical control and other comprehensive measures, and plan to carry out the third -generation American white moth prevention and control in late August.

As a citizen, what should you do after discovering the American white moth in the community, the garden, and the courtyard? Technical experts support: If the American white moth web screen is found in a large area of ​​the urban area, it should be reported to the urban management garden greening department or community property in time. For some low green belts, if the trees are small, once the screen is found, it is recommended to cut it as much as possible and crushed it on the spot. Do not wait for the drug to spray. It is more environmentally friendly and safe without public control and killing.

Technical experts particularly reminded that American white moths are best to prevent when living on the Internet, and it is very simple to remove manual. Once the net is broken, it spreads everywhere, and it is unlikely to be cleaned by hand.

In addition, in order to prevent and control American white moths, relevant departments have invested a lot of funds every year, and the cost of prevention and control is high. If this work can be controlled by the whole people and early warning, it can greatly reduce the investment of human and material resources.
