Abstract
A study on the plant parasitic nematodes (Tylenchida) in JeJu province has been undertaken to know the kinds and distribution of the nemic fauna. The 42 samples taken from 28 kinds of host plants were used. 1. The 22 species belonging to 16 genera in 10 families were discovered in this study and among them Meloidogyne was the most common and widely distributed genus, composing $25\%$, followed by Helicotylenchus $15\%$, Criconemoides $14\%$, Tylenchus $10\%$, Pratylenchus $6\%$, Neolobocriconema $6\%$, Aphelenchus $6\%$, Aphelenchoides $6\%$, Hirshmaniella $3\%$, Heterodera $3\%$ Nothotylenchus $1\%$, Tylenchorhynchus $1\%$, Merlinius $1\%$, Rotylenchus $1\%$ Discocriconemella $1\%$ and Hemicriconemoides $1\%$. 2. The ll species belonging to 10 genera in 7 families such as Nothotylenchus acris, Tylenchorhynchus dubius, Merlinius nothus Pratylenchus minyus, Pratylenchus thornei, Hirshmaniella imamuri, Rotylenchus robustus, Helicotylenchus erythrinae, Meloidogyne arenaria, Discocriconemella hengsungica and Aphelenchoides besseyi were newly discovered species in JuJu province.
제주도내 제주시를 비롯한 각 읍 면에서 28종의 기생식물, 42개 재료를 채취하여 식물기생성 선충을 조사한 결과를 요약하면 다음과 같다. 1. 제주도의 식물기생성선충으로는 2아목 10과 16속 22종이 발견되었으며 속별분포율을 보던 Meloidogyne가 $25\%$로 가장 높은 분포율을 나타내었고 다음이 Helicotylenchus로 $15\%$이었으며 Criconemoides $14\%$, Tylenchus $10\%$, Pratylenchus $6\%$, Neolobocriconema $6\%$, Aphelenchus $6\%$, Aphelenchoides $6\%$, Hirshmaniella $3\%$, Heterodera $3\%$, Nothotylenchus $1\%$, Tylenchorhynchus $1\%$, Merlinius $1\%$, Rotylenchus $1\%$, Discocriconemella $1\%$, Hernicriconenoides $1\%$로 나타났다. 2. 제주도에서 새로 발견된 종은 Nothotylenchus acris, Tylenchorynchus dubius, Merzinius nothus, Pratylenchus minyus. Pratylenchus thornei. Hirshmaniella inmamuri, Rotylenchus robustus, Helicotylenchu erythrinae, Meloidogyne arenaria, Discocriconemella hengsungica, Aphelenchoides besseyi 등으로 2아목 7과 11종이었다.
