Abstract
Pine wilt disease(PWD)is a major invasive forest pest.Based on the actual occurrence of PWD in Shuanggang Town,Tongcheng City,Anhui Province,this paper summarizes the measures,implementation effects and key findings adopted in the integrated prevention and control of this disease in the study area.The PWD occurrence in the study area was severe in both 2020 and 2021,with the affected area reaching 72.27 hm² and 70.73 hm² respectively.In response to the serious epidemic situation,the study area promptly implemented a series of technical measures,including establishing a routine patrol and monitoring system,conducting special autumn surveys,carrying out the forest chief patrol system,performing regular field inspections,and conducting no fewer than 2 comprehensive inspections-coverage UAV(unmanned aerial vehicle)surveys during each of the two time periods(April-May and November-December).Additionally,emergency measures were taken to immediately clear abnormally dead pine trees,and real-time records were kept regarding the number of felled trees,the disposal of infected wood and large branches during the control period.UAV aerial spraying was applied to control the vector insect of PWD(Monochamus alternatus)using a 20 000-fold dilution of 48%thiacloprid suspension concentrate(SC),and the efficacy of aerial spraying was verified by comparison with the trap monitoring method.The integrated prevention and control objectives for the disease in the study area were achieved.Furthermore,this paper analyzes the key findings for future PWD prevention and control work,such as strengthening joint prevention and control with adjacent regions,expanding the application of satellite remote sensing technology for monitoring,enhancing the quarantine of transported timber and the frequency of regular field monitoring,and planting native tree species(e.g.,Liquidambar formosana or Camellia oleifera)to establish mixed forests for stand structure optimization.This study provides a reference for PWD control in other regions.关键词
