초록

토마토 시설재배에서 고온기에 온습도를 조절할 목적으로 사용되는 이류체 포그시스템이 가루이 방제에 미치는 효과를 알아보고, 이를 활용한 효과적이고 친환경적인 가루이 예방 및 방제 방법을 모색하기 위해 총 2회에걸쳐실험을수행하였다. 1차실험에서는 포그처리의가루이 방제 효과를 구명하였고, 구역별가루이 분포를조사하였다. 2차실험에서는 이류체 포그시스템이가루이의 수직분포와 운동성에 미치는 영향 및 방제효과를 검증하는 실험을 수행하였다. 1, 2차 실험에서 이류체포그시스템이 가루이의 개체수와 운동성을 감소시키는 효과가 인정되었다. 시설 내에서 가루이는 출구에서 먼쪽의구역에높은 밀도로 분포하며, 이류체 포그시스템을 작동하였을 때 가루이의 수직분포가 달라지는 것이 조사되었다. 따라서 이류체 포그시스템을 가루이의 예방및방제에 사용하되, 밀도가 높은구역의기주식물 중상부에 황색점착트랩을 설치하여 가루이를 더욱효과적으로 방제할수있을 것으로사료된다.

Two experiments were designed and executed to measure the effectiveness of the two-fluid fogging system in controlling whiteflies in tomato cultivation. The two-fluid fogging system that lowers temperature and raises humidity in greenhouses provides an eco-friendly method of preventing damages from whiteflies. The first experiment elucidated the effect of fogging treatment on the elimination of whiteflies and investigated the sectional distribution of whiteflies. The second experiment analyzed the vertical distribution, the motility of whiteflies and reduction of the number of whiteflies under the fogging system. The result of the experiments showed that the fogging system lowered the number of whiteflies and decreased their motility significantly. It affected the vertical distribution of whiteflies as well. Based on these experiments, we strongly recommend using the fogging system to prevent and control whiteflies in greenhouses, in addition to installing yellow sticky traps in the areas that have the highest density of whiteflies.
