느타리버섯 재배사에서 버섯혹파리(Mycophila speyeri)에 대한 한국산 곤충병원성 선충 Steinernema carpocapsae 포천 계통, S. logicaudum 논산 계통, S. glaseri 동래 계통, Heterorhabditis bacteriophora 함양 계통과 Heterorabditis sp. 경산 계통의 방제효과를 평가하였다. 5종의 한국산곤충병원성 선충 중 버섯혹파리에 대한 방제는 steinernema 속 3종보다 Heterorhabditis 속 2종의 효과가 높았다. 방제효과가 가장 높았던 종은 H. bacteriophora 함양 계통이었으며, $1.5 m^2$ 당 $1 imes10^6$ 마리로 처리한 7일, 14일, 21일째 방제효과는 창녕에서 $49.0\%,;89.5\%,;89.1\%$였고, $1 imes10^5$마리로 처리했을 때는 $46.5\%,;76.7\%,;85.4\%$였다. 그리고 진주에서는 $1 imes10^6$마리로 처리한 7일, 14일, 21일째 방제효과가 $54.0\%,;74.5\%,;79.8\%$였으며, $1 imes10^5$마리로 처리했을 때는 $49.0\%,;76.6\%,;61.1\%$였다.
The potential of five entomopathogenic nematodes, Steinernema carpocapsae Pocheon strain, S. logicaudum Nonsan strain, S. glaseri Dongrae strain, Heterorhabditis bacteriophora Hamnyang strain, and Heterorabditis sp. Gyeongsan strain were evaluated as biological control agents against a mushroom fly, Mycophila speyeri in the mushroom, Pleurotus ostreatus cultivation house. Control effect of M. speyeri was significantly different according to nematode species. Heterorhabditis was more effective than Steinernema. H. bacteriophora Hamnyang strain showed the highest control effect representing $49.0\%$ (7 days), $89.5\%$ (14 days) and $89.1\%$ (21 days post-treatment) at the rate of $1 imes10^6$ and $46.5\%$ (7 days), $76.6\%$ (14 days) and $85.4\%$ (21 days post-treatment) at the rate of $1.0 imes10^5$ Ijs/$1.5 m^2$ in Changnyoung, Gyeongnam, respectively. In Jinju, Gyeongnam, control effects of the sa me species were $54.0\%$ (7 days), $74.5\%$ (14 days), and $79.8\%$ (21 days post-treatment) at the rate of $1 imes10^6$ and $49.0\%$ (7 days), $76.6\%$ (14 days), and $61.1\%$ (21 days post-treatment) at the rate of $1.0 imes10^5$ Ijs/$1.5 m^2$, respectively.
