Abstract: Pine wilt disease caused by nematode could be controlled with three ways: (1) Applying a ttractant to killing the vector, adult of Monochamus alternatus~ (2) Releasing Scleroderma guani to control the larva of Japanese pine sawyer; (3) Applying the attractant and releasing S. guani, simultaneously. The result shows that the three measures were all effective to control the pine wilt disease. M99-1 attractant could make dead tree percentage to decrease 61%. If the M99-1 attractant and releasing S. guani are applied simultaneously, the percentage of pine wilt disease will be reduced 77%.
