Abstract:From2015to2017,through the use of green control measures such as hanging traps,releasing Dastarcus heloporoides,and timely cleaning of dead pine trees in the pilot demonstration area,the prevention and control of Monochamus alternatus was carried out.The parasitic rate of Dastarcus heloporoides to Monochamus alternatus is greatly improved, with the average parasitic rate of 62.73%,The number of dead pine trees and the number of adults in the forest were declining year by year.The control effect is remarkable.
