Abstract

Plant-parasitic nematodes were surveyed at peach orchards in Gyeongbuk province for three years from 2000 to 2002. Species, density, frequency, Simpson's index, Shannon and Wiener index, and prominence value were analyzed. Plant-parasitic nematodes were isolated from 97 orchards out of 124 orchards. More important plant-parasitic nematode genera on peach were Tylenchorhynchus nudus, Criconemoides informis, Paratylenchus elachistus, Pratylenchus vulnus, and Helicotylenchus digonichus. Aphelenchus sp., Tylenchus sp., Heterodera sp., Scutellonema sp. were found, but were not important. Root-knot nematodes were not found even though they were serious in foreign countried.

복숭아의 주요 식물기생성선충 종류를 밝히기 위하여 2000년부터 2002년까지 3년간 경북지역의 124개 복숭아 과원 토양으로부터 선충을 분리하고 선충의 종류, 밀도, 빈도(Frequency), 우점도(Simpson's index), 다양성지수(Shannon and Wiener index), 중요도(Prominence value)를 분석하였다. 식물기생성 선충은 총 124지점 중 97지점에서 발견되었으며 우점도는 0.717-0.881, 다양성지수는 0.221-0.286로 복숭아는 다양한 종류의 식물기생성선충에 의하여 피해를 받기보다는 몇몇 우점하고 있는 식물기생성선충에 의하여 피해를 받고 있었다 복숭아과원에서 중요한 식물기생성선충은 Tylenchorhynchus nudus, Criconemoides informis, Paratylenchus elachistus, Pratylenchus vulnus, Helicotylenchus digonichus 순이었고, 그 외 Aphelenchus sp., Tylenchus sp., Heterodera sp., Scutellonema sp. 등이 검출은 되었으나 중요종은 아니었다. 이번 조사에서 특히 국내 복숭아과원 토양에는 Paratylenchus elachistus가 널리 분포하고 있었으며, 반면 외국에서 심각한 문제가 되고 있는 뿌리혹선충류는 발견되지 많았다.
