Prevention and control of forestry pests such as the American white moth in the city in 2021

American white moth is a worldwide quarantine pest, with a wide range of hosts, strong reproductive capacity, rapid spread and other characteristics, in our city occurs three generations a year, to pupate overwintering, the occurrence period is in April to October every year. Since the beginning of spring this year, there has been a cold spring in our city, resulting in the development of the first generation of American white moths being delayed by about a week compared with the same period, and the coexistence of pupae, adults, eggs and larvae in various places, and the difficulty of prevention and control has increased significantly. Since the middle of July, the city has continued to be hot and rainy, the survival rate of white moth eggs hatching and the ability to feed and grow have improved, coupled with frequent precipitation and increased precipitation, which have affected the effectiveness of prevention and control, and the occurrence of insects is multi-faceted and high-incidence. According to the insect situation monitoring report of the State Forestry and Grassland Administration, the American white moth shows a more and more heavy trend in Beijing, Tianjin, Hebei, Shandong, Henan, Jiangsu and other provinces and cities; according to the provincial department of natural resources and the monitoring of the insect situation in our city, the American white moth and Yang Xiaozhou moth are widely occurring in Jinan, Tai'an, Heze, Zaozhuang and the counties and urban areas of our city.

First, the occurrence of prevention and control overview

In 2021, the overall occurrence of major forestry pests such as the American white moth and Yang Xiaozhou moth in the city is heavier than usual, with a total occurrence area of 179,600 mu, of which the American white moth occurs in an area of 141,700 mu and the Yang Xiaozhou moth occurs in an area of 37,800 mu; the counties and municipalities have invested a total of 40.5042 million yuan in prevention and control funds, and the area of prevention and control operations has been 5.4652 million mu, of which the flight prevention area is 4.082 million mu and the ground defense area is 1.3832 million mu, effectively controlling the insect situation on highways and national and provincial highways , inter-city trunk roads, city periphery, park green areas, mountain hills and other key areas of the spread and occurrence of harm.

2. Work carried out

(1) Strictly implement responsibilities and form a synergy of work. The municipal party committee and the municipal government attach great importance to the prevention and control of forestry pests such as pine wood nematode disease and the American white moth, and the main leaders of the municipal party committee and the municipal government personally give instructions for scheduling and in-depth front-line research and inspection, and the leaders in charge of the municipal government have successively made 7 special research and deployment, made instructions and supervision arrangements. The municipal government and the county and municipal governments have successively set up forestry and grassland pest prevention and control headquarters, refining the responsibilities of 14 member departments, such as the overall coordination of the natural resources department for the prevention and control of the whole territory, the housing department responsible for the property management area, the urban management department responsible for the urban area, the transportation department responsible for the national and provincial highways, and the urban and rural water affairs department responsible for the water system embankment, etc., and implemented regular research and judgment meetings and dispatch reports, and established a working mechanism of joint management, division of labor linkage, and implementation at all levels.

(2) Pay attention to monitoring and census and implement scientific prevention and control. Four state-level forestry pest center monitoring points in Qufu City, Yutai County, Jinxiang County and Liangshan County and three provincial-level forestry pest centers in Surabaya County, Jiaxiang County and Wenshang County have been built, 285 new monitoring points at the municipal and county levels have been set up, all monitoring points have been uniformly numbered, black light lamps and traps have been hung, a monitor has been equipped, the situation has been recorded in a timely and accurate manner, and the monitoring results have been reported every two days. In 2021, the city will release 135 phases of insect monitoring and forest protection and 150 periods of insect records. Increase the intensity of business guidance, supervise the counties and municipalities to set up a White Moth epidemic investigation team in the United States, achieve full coverage of the epidemic investigation, guide the counties and municipalities to coordinate the monitoring and forecasting with the aircraft and ground prevention and control when bidding for the prevention and control contract, and give play to the monitoring and prevention role of professional prevention and control institutions; after the end of each generation of prevention and control, immediately guide the counties and municipalities to carry out inspection and acceptance of the prevention and control results, and timely supplement the prevention and control of areas where the effect is not obvious or leaky, and improve the effectiveness of prevention and control.

(3) Strengthen supervision and inspection to improve the effectiveness of prevention and control. At the beginning of the year, the Municipal Headquarters issued the "Jining City 2021 Major Forestry Pest Prevention and Control Work Plan", which details the tasks of the county and urban departments and the measures of each time stage. In April, May, July, September and other key stages of prevention and control, dispatch and notification meetings were successively held, and the municipal command headquarters organized all member units to guide and supervise the county, went deep into the urban communities, towns and villages in each county and urban area, along the road, around rivers and lakes, nursery forest farms and other key locations to conduct field investigations, established and implemented daily dynamics, weekly reports, implementation of key issues within a time limit, tracking and supervision of the ledger and other work systems, and effectively compacted the territorial responsibilities, supervision responsibilities and main responsibilities of various departments and units. The Municipal Headquarters has organized 8 centralized supervision and inspections, more than 260 person-times, and issued 22 notices of removal within a time limit. The Municipal Housing and Urban-Rural Development Bureau, the Municipal Urban Management Bureau, the Municipal Transportation Bureau and other major member units have also formulated and issued plans and issued notices, and respectively organized the internal prevention and control supervision and inspection of the system, effectively promoting the implementation of the work.
