Abstract

We studied the efficacy of the 'Natural Enemy in First (NEF)' technology in controlling thrips and aphids in tomato greenhouses, relative to the natural enemy and conventional chemical treatments. This technology combined the use of natural enemies of the pests (parasites/predators) with their food sources/habitats, and the treatment commenced at the time of planting. The 'NEF' technology, for the control of thrips, had an efficacy 32% higher than the natural enemy treatment, and 82% higher than the conventional chemical treatment. The average population density of aphids after the treatment was not significantly different among all treatments.

시설토마토에서 사전에 해충밀도를 예찰 하지 않고 작물 정식과 동시에 적용한, 기생성/포식성 천적과 그들의 먹이원/서식처가 결합되어 있는, 'Natural Enemy in First (NEF)' 기술의 총채벌레와 진딧물 방제효과를 확인하였다. 처리 후 12주차에 NEF 처리구에서 총채벌레 밀도억제 효과는 천적처리구 및 관행방제구에 비해 각각 32%와 82% 더 높았다. 처리 후 진딧물의 밀도는 모든 처리구에서 낮게 유지되어 처리구간 유의성 있는 차이를 확인할 수 없었다.
