It is difficult to identification between Bursaphelenchus spp. and Pine Wood Nematode (PWN) by morphological characteristics without expertise about nematode taxonomy. Furthermore, Baermann funnel method, which is nematode extraction method from wood chips or soil, requires at least 24 hours to extract nematode that is unsuitable to rapid diagnose the Pine Wilt Disease (PWD). For these reasons, the aim of this experiment is not only to improve accuracy of a PCR based method but also to reduce total experiment time for detection Bursaphelenchus spp. and PWN in the wood chips of PWD infected pine tree. In this experiment, we had been employed two PCR primer sets, which were originated from PWN specific Internal Transcribed Spacer (ITS) sequence region and Bursaphenchus spp. universal mitochondrial Cytocrome Oxidase subunit I (mtCOI) sequence region in order to discrimination between Bursaphelenchus spp. and PWN at the same PCR reaction. This experimental procedure was able to reduce experiment time and cost as well as to improve accuracy of detection than previous PCR based detecting method by not using Baermann funnel method and commercial genomic DNA extraction kit but using direct pine wood chips lysis method.
