August 7, 2007 (Lunar June 25, 2007), What is the American white moth?. On August 7, 2007, American white moth was found in eight suburban counties of Beijing, involving 26 towns and 51 villages. The second-generation American white moth larvae and the first-generation American white moth adults were detected. There was no disaster in Beijing due to early discovery, early reporting and early disposal. Qiang Jian, deputy director of Beijing Municipal Bureau of Landscaping and Greening, made the above remarks at the press conference on the establishment of the "Green Olympics" held here on the 7th. He said that the number of adults of the first generation of American white moth found in monitoring this year was only 4% of that of the same period last year, and the number of larvae of the second generation of American white moth was only 5% of that of the same period last year, and the occurrence range was significantly reduced compared with that of the same period last year. Qiang Jian illustrated the important measures taken by Beijing to control American white moth with a series of figures: this year, Beijing dispatched more than 170,000 prevention and control personnel, set up more than 17,400 larval insecticidal lamps, purchased more than 2,000 sets of imported special attractants for American white moth, released 1.67 billion Zhou's gnawing bees, and organized 637 aircraft prevention and control sorties in spring and summer to spray areas where larvae were found in all directions. To ensure the Green Olympics, Beijing invested special funds, set up a special prevention and control headquarters, and set up a virus production workshop with American white moth as the main prevention and control object. The first batch of products has been applied to 90,000 mu. Beijing has also stepped up spot checks, inspections and general surveys, and conducted key inspections on key greening projects such as major roads, railways and rivers, as well as areas where American white moths have occurred. In order to prevent and control it from the source, Beijing and neighboring provinces and cities have carried out forest pest control work, and supported Hebei Province with more than 2 million yuan of free prevention and control funds, which were used to cull pests, overwintering pupae, purchase pesticide sprayers, etc., effectively controlling the number of American white moth larvae.
