Abstract:	調查新竹縣關西鎭、芎林鄉、新埔鎮、峨眉鄉四個鄉鎮、49處生長良好之海梨柑果園土壤中根腐線蟲(Root lesion nematode Pratylenchus spp.)族群危害情形，結果顯示無線蟲危害者僅8處，佔16.33%，其餘爲極輕微危害者有41處，佔83.67%。顯示新竹地區海梨桶柑園內根腐線蟲發生比例頗高，即使在生長良好的果園中，仍有如此高比例之寄生性線蟲存在，表示其潛在性的危害極爲嚴重，如不及早加以防治，可能造成嚴重損失。 A survey was conducted on damages caused by root lesion nematodes and the nematode population in 49 Hai-li tangor orchards distributed in Kunsi, Chunlin, Shinpu, and Earmay in Shiuchu in 1998 December was conducted.
