  Provided is a method for determining whether or not infection with Bursaphelenchus xylophilus exists. The method includes a first sap extraction step of immersing a first fragment sample taken from a first tree in a solvent to extract a first sap contained in the first fragment sample of the first tree, a first concentration analysis step of analyzing a first concentration of an organic compound contained in the first sap, and a first comparison step of comparing the first concentration with a reference concentration of the organic compound contained in the sap of a tree that has not been infected with Bursaphelenchus xylophilus, so as to determine whether or not a coniferous tree is infected with Bursaphelenchus xylophilus.

  本发明提供了一种确定是否存在嗜木毛囊虫感染的方法。该方法包括第一树液提取步骤：将取自第一树的第一片段样本浸入溶剂中，以提取第一树的第一片段样本中所含的第一树液；第一浓度分析步骤：分析第一树液中所含有机化合物的第一浓度；以及第一比较步骤：将第一浓度与第一树液中所含有机化合物的参考浓度进行比较、第一比较步骤：将第一浓度与未感染嗜木毛囊虫的树木的树液中所含有机化合物的参考浓度进行比较，以确定针叶树是否感染了嗜木毛囊虫。

  [EN] The present invention relates to a method for determining whether or not infection with Bursaphelenchus xylophilus exists, the method comprising a first sap extraction step of immersing a first fragment sample taken from a first tree in a solvent to extract a first sap contained in the first fragment sample of the first tree, a first concentration analysis step of analyzing a first concentration of an organic compound contained in the first sap, and a first comparison step of comparing the first concentration with a reference concentration of the organic compound contained in the sap of a tree that has not been infected with Bursaphelenchus xylophilus, so as to determine whether or not a coniferous tree is infected with Bursaphelenchus xylophilus,
  [FR] La présente invention concerne un procédé pour la détermination de la présence ou non d'une infection par Bursaphelenchus xylophilus, le procédé comprenant une première étape d'extraction de sève consistant à immerger un premier échantillon formé d'un fragment prélevé sur un premier arbre dans un solvant pour extraire une première sève contenue dans le premier échantillon formé du fragment du premier arbre, une première étape d'analyse de la concentration consistant à analyser une première concentration d'un composé organique contenu dans la première sève, et une première étape de comparaison consistant à comparer la première concentration avec une concentration de référence du composé organique contenu dans la sève d'un arbre qui n'a pas été Infecté par Bursaphelenchus xylophilus, de manière à déterminer si oui ou non un conifère est infecté par Bursaphelenchus xylophilus.
