Rotylenchus arsenjevi are reported for the first time in Korea. The Korean species differs slightly by having a hemispherical lip region and a slightly shorter tail than the original description (c=38.2-68.7 vs 36-41). Male was founded firstly from Korea and described. Geocenamus adakensis were collected a second time from Korea at a different locality and habitat. The measurements were compared with original description and the firstly collected specimen in Korea.

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.

The conversion of rice-fields to uplands is increased in last 8 years due to the government's policy. To obtain basic informations on plant-parasitic nematodes in converted uplands, we surveyed nematodes associated with crops cultured on the ridge of the rice-fields. The crops mostly cultivated at the ridge of rice-field were soybean (66%), red bean (21%), and perilla (13%). Ten important plant-parasitic nematodes species were identified: Helicotylenchus sp., Heterodera glycines, Meloidogyne arenaria, M. javanica, M. hapla, Paratylenchus projectus, Pratylenchus coffeae, P. neglectus, Rotylenchus incultus, Trichodorus sp. Tylenchorhynchus crassicaudatus, and T. claytoni. Among them, Rotylenchus incultus was the most common plant-parasitic nematode in all three crops. The ridge is a border of rice field, thus plant-parasitic nematodes infested on ridges should be cautioned for future cropping.

During the survey on spiral nematode (Hoplolaimidae) from Korea, Pararotylenchus blothrotylus Baldwin & Bel, 1981, Rotylenchus feroxcis Eroshenko, 1981 and Scutellonema conicephalum Sivakumar, 1982 were newly recorded from Korea.

Survey on potato parasitic nematodes has been undertaken in order to find distribution of the nemic fauna. 41 soil samples were taken from potato fields in Gyeongbug, Gyeongnam and Gangweon provinces. Twenty four species belonging to 16 different genera were identified. Potato cyst nematode, Globodera rostochiensis was not found in the areas. Potato-rot nematode, Ditylenchus destructor and stem nematode, Ditylenchus dipsaci were found from several potato fields and population density high and showed damage to the crops. Root-lesion nematode, Pratylenchus minyus, Pratylenchus penetrans, Pratytenchus thornei and Pratylenchus vulnus were found and their population of these four species were high depending on the fields. Root-knot nematode, Meloidogyne hapla and Meloidogyne incognita were found. M. hapla was found only in Gangweon province and the population density was high. M. incognita was found at Milyang in Gyeongnam province. Spiral nematode, Heticotylenchus digonichus, Helicotylenchus dihystera, Helicotylenchus pseudorobustus, Rotylenchus orientalis and Rotylenchus pini were found. Aphelenchoides saprophilus, Criconemoides informis, Ditylenchus destructor, D. dipsaci, Helicotylenchus digonichus, H. dihystera, Hemicriconemoides intermedius, Meloidogyne hapla, Psilenchus hilarulus, Pratylenchus minyus, and Xiphinema americanum were first found from potato fields in Korea.

Survey on soybean parasitic nematodes has been undertaken in order to get an ideas about the distribution of nemic fauna. Total 71 soil samples were collected from soybean fields in Gyeongbug and Chungbug provinces. Eighteen species belonging to fourteen different genera were found associated with soybean, Glycine max. The results were as follows: Aphelenchus avenae, Circonemoides informis, Ditylenchus dipsaci, Helicotylenchus pseudorobustus, Heterodera glycines, Hirschmanniella imamuri, Meloidogyne hapla, Meloidogyne incognita, Paratylenchus pandus, Pratylenchus thornei, Pratylenchus vulnus, Psilenchus hilarulus, Rotylenchus sp. Tylenchorhynchus clay toni, Tylenchorhynchus dubius, Tylenchorhynchus nudus, Tylenchus sp. Xiphinema americanum were found in soybean fields. In frequency of occurring nematodes by localities, soybean cyst nematode was higher in Chungbug by $70\%$, while $50\%$ in Gyeongbug. But rook-knot nematode was higher in Gyeongbug by $54.1\%$, while $19.1\%$ in Chungbug. In density of nematode, Heterodera was the most dominant as 200.4 populations per 100ml soil, Meloidogyne as 107.1 populations, Rotylenchus, Xiphinema, Aphelenchus in decreasing order. In survey of loss, density of soybean cyst nematode in heavily infested fields was 155 cysts per 100ml soil while 35 cysts in slightly infested fields. Seventy percent of soybean yields was decreased when comparing with average 64.2kg/10a in heavily infested fields and average 209.5kg/10a in slightly infested. Correlation coefficients among number of soybean cyst and yields, pod weight, number of pod was negative as r- 0.57, 0.47, 0.38 over all localities.
