This paper studies on the effects of new biological control system, particularly on banker plants of Orius laevigatus to control Frankliniella occidentalis on rose. Orius banker plants for Frankliniella occidentalis were investigated under the conditions of photoperiod 16L:8D, 70 ± 5% RH and 22 ± 2oC. Three types of plants(Sedum sarmentosum, ortulaca grandiflora, Mentha rotundifolia) were used to effectiveness verification of egg taking. And P. grandiflora has been selected as the banker plants for O. laevigatus. Result from this banker plants clearly demonstrated that the population of F. occidentalis was kept under the economic threshold level (1.9 per flower).
