Abstract

An fungus gnat, Bradysia agrestis in the family Sciaridae was collected from Pinus spp. seedlings. This pest is a newly recorded insect from P. thunbergii, P. rigida, P. rigitaeda, and P. densiflora seedling. Brief morphological characters, damage symptom, host plants associated with the B. agrestis were recored. Significant variation in damaged of Pinus spp. seedling was attributed to differences between pine species(P. thunbergii : 15.4-20.0%, P. rigida : 23.1-48.8%, and P. rigitaeda : 13.8-67.5%, respectively) and sowing times(May : P. densiflora, 0%; P. rigida, 0%, July : P. densiflora, 20.0%; P. rigida, 49.4%, respectively).

소나무류 묘목을 가해하는 해충을 채집하여 동정한 결과, 검정날개버섯파리과(Sciaridae)에 속하는 작은뿌리파리(신청)(Bradysia agrestis)로 확인되었으며, 해송, 소나무, 리기다소나무, 리기테다소나무를 가해하는 새로운 해충으로 기록되었다. 본 종의 간략한 형태적 특정, 피해증상, 기주를 소개하였다. 소나무 종류에 따른 피해율은 해송(15.4-20.0%)보다 리기다소나무(23.1-48.8%)와 리기테다소나무(13.8-67.5%)가 피해를 많이 받았으며, 파종시기에 따른 피해율은 5월(0%)보다 7월(소나무 : 20.0%, 리가다소나무 : 49.4%)에 피해가 심하며 파종시기별로 피해율의 차이가 있었다.
