台灣地區茶園鞘線蟲Hemicriconemoides kanayaensis和新紀錄種H. californianus (Nematoda: Criconematoidea, Criconematidae)之鑑定

Nine populations of Hemicriconemoides spp. has isolated by modified Baermann funnel method from the rhizosphere soil of tea plants among 7 major tea production areas in Taiwan since April. 2006. Comparisons of the morphology, morphometrics and ribosomal DNA fragment sequences (include full 5.8S gene, ITS-1, ITS-2 and partial 18S and 28S gene) has yielded 6 populations being H. kanayaensis Nakasono & Ichinoe, 1961 and 3 populations being H. californianus Pinochet & Raski, 1975. H. californianus was the first reported in Taiwan. In this study, additional morphometric data (including c', m, EP, P. VL and VW of female; c', spicule. EP, P. Tail and ABW of male) and SEM figures for these two sheath nematode were provided. The representative sequences of rDNA fragment of H. kanayaensis and H. californianus had the size of 1043 bp and 1051 bp, respectively, and were firstly submitted to GeuBank.
