  • 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.

  • Natural Enemy in First (NEF) method is an ecological engineering application technology for natural enemies and was applied to strawberry in a smart farm-type greenhouse to evaluate its effect on the density of thrips and aphids. The control group was treated with pesticide and compared with the NEF treatment group, in which Orius minutus and Portulaca sp. were used as a natural enemy and habitats for thrips and aphids. The density of pests in the NEF group was effectively managed and similar to that in the control group.
