摘要

Pine wilt disease, caused by the pinewood nematode, Bursaphelenchus xylophilus, is a serious problem in southern Korea. The disease was first reported in Busan city in 1988 (Yi et al., 1989) and has spread to several southern and middle areas of the Korean peninsula. As Pinus densiflora and P. thunbergii are predominant tree species in Korean forests and are very susceptible to the pinewood nematode, ecological and economical damage is substantial. Control of this disease depends on fumigation of disease-infected trees, aerial application of synthetic pesticides against Monochamus alternatus, the insect vector of this disease, or injection of nematicides (Korea Forest Service, 2003). However, human health concerns regarding commercial nematicides, factors such as increased cost of nematicide, labour and application have made pine wilt disease control difficult and so alternative control methods or less toxic nematicides need to be developed. Plant essential oils are potential alternatives to current control agents. They constitute a rich source of bioactive chemicals, and are commonly used as fragrances and flavouring agents for foods and beverages (Isman, 2000). We investigated plant essential oils and their components which have nematicidal activity against pine wood nematode.
