The Relations between the Fire of Pine Forest and the Epidemic of Pine Wilt Disease

  • Received Date: 1998-11-16
  • Close relations existed between the pine forest fire and the epidemic spread of pine wilt disease(PWD).The adults of Monochamus alternatus emerged from the fire injury pine trees carried an average of 7 364 nemateodes,which will infect the healthy pines and causes the mortality of pine and epidemic spread of PWD.There are 3 types of PWD associated with the fire of pine forest,i.e.PWD occurs in the same year when forest is burned,PWD occurs in the next year after forest fire,and occurs several years later.It is an effective method for controlling PWD by clear-cutting all the fire dead pines parasitized by beetles and nematodes according to the results of studies.4 new methods can be used in the practice of breaking up the combination of PWD and fire of pine forest.

Abstract: Close relations existed between the pine forest fire and the epidemic spread of pine wilt disease(PWD).The adults of Monochamus alternatus emerged from the fire injury pine trees carried an average of 7 364 nemateodes,which will infect the healthy pines and causes the mortality of pine and epidemic spread of PWD.There are 3 types of PWD associated with the fire of pine forest,i.e.PWD occurs in the same year when forest is burned,PWD occurs in the next year after forest fire,and occurs several years later.It is an effective method for controlling PWD by clear-cutting all the fire dead pines parasitized by beetles and nematodes according to the results of studies.4 new methods can be used in the practice of breaking up the combination of PWD and fire of pine forest.
