Predatory nematodes are ubiquitous and feed on soil microorganisms including plant parasitic nematodes. They reduce populations of plant parasitic nematodes in virtually all soils because of their constant association with plant parasitic nematodes in the rhizosphere. Predatory potential of several species of predacious nematodes, belonging to the orders Mononchida, Diplogasterida, Dorylaimida and Aphelenchida, have been studied in detail on plant parasitic nematodes but most of the studies were based on in vitro experiments. A review of progress on the use of predatory nematodes as biological control agents of plant parasitic nematodes reveals that advocacy for predatory nematodes dates back to the early $20^{th}$ century; nevertheless, their potential has begun to be studied in recent years. Information on the efficacy of predatory nematodes under field conditions is lacking; however, some predatory nematodes have given very promising results against plant parasitic nematodes. This article summarizes research progress to date on predatory nematodes and discusses about their possible use in the management of plant parasitic nematodes.

1995년 전국 8개도 37개점의 밭토양으로부터 분리한 52균주의 선충 포식성곰팡이를 이용하여 실내 및 온실에서 부식성선충과 뿌리혹선충을 이용하여 포식력을 비교하였다. 실내검정에서 부식성선충에 대하여 91% 이상의 포식력을 보인 균주는 51균주였고, 부리혹선충에 대하여는 26균주였으나, 온실 검정에서는 81%의 포식력을 보인 균주가 3균주로 온실검정과 실내 검정간 상관 유의성은 없었다. 선발된 3균주는 부식선충 및 뿌리혹선충에 대하여 실내 및 온실실험에서 모두 높은 포식력을 나타내었다. 이 실험으로 미루어 볼 때, 천적 포식성곰팡이 선발 시험은 반드시 포장 조건과 가장 유사한 상태에서 실시되어야 할 것으로 보인다.

Monacroporium ullum sp. nov. the captures nematodes on adhesive spherical knobs was isolated from soil around Codonopsis lanceolata at Ulleung island, Korea. The spindle-shaped conidia sized $17-44{\mu}m\;(26.5{\mu}m)\;long,\;7-10{\mu}m\;(8.1{\mu}m)$ wide, containing from 1 to 4 cross-walls but most often divided by 2 septa (47%). Resting bodies sized $57{\times}30{\mu}m$. Arthrobotrys amerospora has almost spherical non-septate conidia with a small truncate protuberance at the base and sized $20-27{\mu}m\;(23.3){\mu}m$ long and $11-17{\mu}m\;(14.1){\mu}m$ wide. Conidiophores are somewhat longer $362.8{\mu}m\;(311-418{\mu}m)$ than its original description ($75-250{\mu}m$).

Dactylella pseudoclavata that captures nematodes in adhesive networks was isolated from nematode-infested strawberry plants from Andong, Korea. It produces obclavate, 0-1 septate conidia, $30-40{\mu}m$ long and $8-11{\mu}m$ wide, with round distal ends and bases shaped like bottle-necks. The conidiophores were simple, occasionally branched, $150-300{\mu}m$ long, producing 1-4 conidia at the apex. Chlamydospores were abundant, intercalary or catenulate, yellowish to brown, globate or subglobate, wart on the surface, $30-35{\times}25-30{\mu}m$ in size. This is the first report of Dactylella pseudoclavata in Korea.

선충 포식성곰팡이는 선충 포획 기관을 만들어 선충 포획 후 양분을 섭취하는 곰팡이다. 이들 중 Arthrobotrys flagrans와A. superba에 대한 특성들 중 보고될 때 생략된 것이 있어 두 종을 토양으로 부터 분리하고 순수배양하여 추가적으로 조사하였다. 선충 종류별 포식력, 포식기관의 형태·크기, 분생포자의 형태·크기, 분생포자병의 형태, 후막포자 등을 조사하였으며, ITS rDNA 염기서열의 분자계통학적 분석을 토대로 종 동정을 실시하였다. 또한 1981년 처음으로 선충 포식성곰팡이가 국내에서 보고된 이래로 현재까지 총 21종이 발견되었으나 이들에 대한 분류 체계와 주요 식별 형질이 없는 상황이었기에 제공하였다. 이를 바탕으로 아직 연구가 많이 진행되지 않은 국내 선충 포식성곰팡이 연구에 기초자료가 될 수 있기를 기대한다.

The short-term effects of low-level contamination by heavy metals (As, Cd, Cu, and Pb) on the soil health were examined by analyzing soil nematode community in soils planted with tomatoes. For this, the soils were irrigated with five metal concentrations ([1, 1/4, $1/4^2$, $1/4^3$, and 0] ${\times}$ maximum concentrations [MC] detected in irrigation waters near abandoned mine sites) for 18 weeks. Heavy metal concentrations were significantly increased in soils irrigated with MC of heavy metals, among which As and Cu exceeded the maximum heavy metal residue contents of soil approved in Korea. In no heavy metal treatment controls, nematode abundances for all trophic groups (except omnivorous-predatory nematodes [OP]) and colonizer-persister (cp) values (except cp-4-5) were significantly increased, and all maturity indices (except maturity index [MI] of plant-parasitic nematodes) and structure index (SI) were significantly decreased, suggesting the soil environments might have been disturbed during 18 weeks of tomato growth. There were no concentration-dependent significant decreases in richness, abundance, or MI for most heavy metals; however, their significant decreases occurred in abundance and richness of OP and cp-4, MI2-5 (excluding cp-1) and SI, indicating disturbed soil ecosystems, at the higher concentrations (MC and MC/4) of Pb that had the most significant negative correlation coefficients for heavy metal concentrations and nematode community among the heavy metals. Therefore, the short-term effects of low-level heavy metal contamination on soil health can be analyzed by nematode community structures before the appearance of plant damages caused by the abiotic agents, heavy metals.
