Abstract

Abstract F. occidentalis (WFT, western flower thrips) is a major pest in artificial chrysanthemum houses.Nnumber of WFT attracted to yellow sticky trap was highest at trap plant and lowest at 15 and 20m placesaway from trap plant. Number of WFT attracted to yellow stick trap when trap plant was placed inchrysanthemum house 30 days after planting (resident WFT) was 4.4~7.7 times more than at 5 and 10 mplaces away from trap plant and when trap plant was placed in chrysanthemum house immediately afterplanting (resident WFT) was 5.7~9.4 times more at 5 and 10 m places away from trap plant. Number ofWFT between the place trap plant located and unlocated was undifferent when cultured chrysanthemumformed flower. In case of the plot that trap plant and natural enemy was used simultaneously, number ofWFT was highter then chemicals plot. In case of the plot that trap plant and chamicals (chemicals wassprayed on trap plant only) WFT was controlled in trap plant place only but density of WFT on 5m and 10mplaces away from trap plant was increased. Therefore, WFT could be controlled effectively by use of trapplant (flowering yellow chrysanthemum) and natural enemy simultaneously. Key words Frankliniella occidentalis, Chrysanthemum, Orius laevigatus, Chemical control, Trap plant
