초록

Effectiveness of Orius strigicollis (Poppius) and Amblyseius cucumeris (Oudemans) as natural enemies against thrips were evaluated on greenhouse green pepper, sweet pepper and cucumber respectively. Control efficacy was calculated by the formula, (D<SUB>control</SUB> - D<SUB>treatment</SUB>)/D<SUB>control</SUB> × 100, where D<SUB>control</SUB> is the average density of thrips on the plots in which any natural enemy was not released and D<SUB>treatment</SUB> is the average density of thrips on the plots in which natural enemies were released respectively. As a result, control efficacies of O. strigicollis against Frankliniella occidentalis (Pergande) on green pepper and sweet pepper were 14.3~99.5% and 21.6~98.3%, respectively. In addition, control efficacy of it against Thrips palmi Kany on cucumber was 61.2-74.4%. Control efficacies of A. cucumeris against F. occidentalis on green pepper and sweet pepper were 12.9~38.3% and 17.1~87.0%, respectively. Control efficacy of it against T. palmi on cucumber was 90.4~97.4%. Field evaluation showed that the prompt applications of natural enemies were effective to reduce the density of thrips. In detail, to control F. occidentalis effectively on green pepper and sweet pepper in spring season, five to six individuals of O. strigicollis per crops should be released three to six times continuously. To control T. palmi effectively on cucumber in autumn, more than 100 individuals of A. cucumeris per crop should be released four times repeatedly.
