This study reports the results of natural enemy application against four insect pests on greenhouse sweet pepper in winter cropping system. Orius laevigatus () was released at two different times (Nov. 2005 & 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 () 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 () 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 1.7/1eaf. To control aphids, Aphidius colemani () was released seven times (Oct. 2004 ~ Jan. 2005), with the transplantation of banker plants (). As a whole, aphid`s population has been successfully reduced to less than 2.0/leaf.

ABSTRACT: This study was performed to investigate the biological characteristics of the brown lacewing Micromus angulatus (Stephens)at four different temperatures (15, 20, 25, and 30 ℃) and 70 ± 10% relative humidity under a photoperiodic regime of 16: 8(L:D) h. Thedevelopmental threshold and effective accumulative temperature from egg to pupa for M. angulatus were 9.6 ℃ and 270.3 day-degrees,respectively. The developmental period of egg, larva, and pupa at 25 ℃ was 4.4, 5.5, and 6.9 days. respectively. The longevity of an adul tfemale M. angulatus was 34.9 days. The oviposition period for M. angulatus was 28.7 days, in which it laid a total number of 515.2 eggsduring its life span. The maximum number of eggs laid by a female in a day was 54.8. Daily consumption by M. angulatus at 25℃was18.9 1 st instars, 47.2 2 nd instars, 57.7 3 rd instars, and 91.0 adults of the glasshouse potato aphid, Aulacorthum solani . Therefore, M. angulatu scould be a promising biological control agent against aphids.
