Research Progress on Biocontrol of Pine Wilt Disease by Microorganisms

Pine wilt disease is a malady caused by a complex interaction of various factors such as pine wood nematodes, host plants, vector insects, associated fungi and bacteria, human economic and logistics activities, and environmental factors. The use of microorganisms to biologically control pine wilt disease is a potentially environmentally friendly means for the prevention and control of the disease. In this study, we carried out a systematic review of the progress in research on the biocontrol of pine wilt disease, by focusing on the pathogenic pine wood nematode, its vector beetle, and the host pine tree species. Then, we discuss the implementation prospects and research trends associated with the biocontrol of pine wood disease. This study provides reference information for the understanding and application of various biocontrol microorganisms in the prevention and control of pine wood disease and for the establishment of an environmentally friendly prevention and control strategy.
