Abstract:Pine wilt disease which is caused by the pine wood nematode is a devastating disease of pine tree, Therefore, the research about pine wilt disease has an important theoretical and practical significance. This article compared the secretory-excretory products of pine wood nematodes and analysis the biological macromolecules by using various dyestuff,in order to provide some theoretical basis for the pathogenic composition of pine wood nemetodes.
