This study reports the results of natural enemy application against four insect pests on greenhouse sweet pepper in winter cropping system. Orius laevigatus (3.3/㎡) was released at two different times (Nov. 2005 and Feb. 2006) to control Frankliniella occidentalis, western flower thrips (WFT). Throughout the cropping season, the lowest level recorded of WFT was less than 2.0 individuals per yellow sticky trap. Amblyseius swirskii (232.3/㎡) was released four times (Nov. 2007 ~ Aug. 2008) to control Bemisia tabaci, tobacco whitefly (TWF). Until July 2008, TWF population had been suppressed lower than 6.6/trap. Phytoseiulus persimilis (44.5/㎡) was released seven times (Apr. 2008 ~ Aug. 2008) to control Tetranychus kanzawai, tea red spider mite (TRSM). As a result, TRSM population was suppressed lower than 1.7/leaf. To control aphids, Aphidius colemani (9.5/㎡) was released seven times (Oct. 2004 ~ Jan. 2005), with the transplantation of banker plants (5.5pot/660㎡). As a whole, aphid's population has been successfully reduced to less than 2.0/leaf.
