Zusammenfassung: | To investigate occurrence of root-knot nematode (RKN) in plastic house of central area of Korea, 132 soil samples were collected in cucumber, water melon, tomato, red pepper and strawberry fields from 2013 to 2015. Among 132 soil samples, 65 soil samples (49%) were infested with RKN and mean density of RKN was 178 second-stage juveniles per $100cm^3$ soil (min. 1 ~ max. 3,947). The frequency of RKN by regional was the highest in Chuncheon with 80%, followed by Cheonan (68%), Nonsan (36%), Buyeo (33%) and Yesan (30%). The frequency of RKN by crops was the highest in tomato with 83%, followed by cucumber (61%), strawberry (41%), red pepper (30%), watermelon (26%). To identify the species of RKN, fifteen populations were selected for representative populations. As a phylogenetic analysis of 15 populations, southern root-knot nematode (Meloidogyne incognita), peanut root-knot nematode (M. arenaria) and northern root-knot nematode (M. hapla) were identified with 47%, 20% and 33% ratio, respectively. In crops, M. incognita, M. arenaria and M. hapla were detected in tomato, M. incognita and M. arenaria were detected in cucumber and watermelon, and M. hapla was detected in strawberry and lettuce. Thus, there should be a continuous management to major species of each crops to prevent dispersal of RKN damages. 2013년부터 2015년까지 국내 중부지방 시설재배지를 대상으로 지역별, 주요 작물별 뿌리혹선충의 감염 현황을 조사하였다. 총 132개 시설재배지 중에서 65개 포장(49%)에 뿌리혹선충이 감염되어 있었으며, 평균밀도는 토양 $100cm^3$ 당 뿌리혹선충 2기 유충 178마리로 나타났다(최저 1-최고 3,947마리). 시군별 감염률은 춘천이 80%로 가장 높았으며, 천안, 논산, 부여와 예산은 각각 68%, 36%, 33%와 30% 순으로 나타났다. 주요 작물별 뿌리혹선충 감염률은 토마토가 83%로 가장 높았으며, 오이(61%), 딸기(41%), 고추(30%), 수박(26%) 순으로 나타났다. 중부지방 시설재배지에서 검출된 뿌리혹선충 대표집단 15개체군의 분자생물학적 종 동정 결과, 고구마뿌리혹선충, 땅콩뿌리혹선충과 당근뿌리혹선충 3종이 각각 47%, 20%와 33%의 비율로 나타났다. 작물별로는 토마토에서 고구마뿌리혹선충, 땅콩뿌리혹선충과 당근뿌리혹선충 총 3종, 오이와 수박은 고구마뿌리혹선충과 땅콩뿌리혹선충 총 2종, 딸기와 상추에서는 당근뿌리혹선충 총 1종이 각각 검출되었다. 따라서, 뿌리혹선충 피해 확산 방지를 위해서는 작물별로 검출된 종을 고려한 방제대책 수립이 필요하다. |
