Abstract

|
|
The fauna and the distribution of plant parasitic namatodes were investigated by sampling about five hundred grams of soil around roots of mulberry trees from 929 mulberry fields in Korea. Of fourteen genera detected on mulberry fields, Paralylenchus aciculus, P. projectus, P. morius, Iielicotylenchus dihystera, Meloidogyne arenaria were found to be parasitic to mulberry. Among them Paratylenchus species were the most abundant in mulberry fields, but Tylenchorhynchus sp., Aphelenchus sp., Helicotylenchus sp., and Meloidogyne sp. were also observed in high frequency. Meloidogyne species were observed in high frequency in Jeonbuk, Gyeonggi and Jeonnam, IIelicotylenchus sp., in Gyeongnam and Gyeonggi, Xiphinema sp., in Jeonbuk and Jeonnam, and Paratylenchus sp., in Gyeonggi, Gyeongbuk, Gyeongnam, and Jeonnam. The growth of mulberry was poor as the increase of density of Paratylenchus sp.
