Abstract
This studies by treatment of 25 individual adults of O. laevigatus and Banker plant with different number of eggs of O. laevigatus were conducted to develop new biological control of the western flower thrips (WFT) in chrysanthemum house. In this work, a treatment of 25 individual adults of O. laevigatus, Banker plant with different number of eggs of O. laevigatus and mixed treatment were applied. Initial WFT density per plant were 5 individuals. WFT density was measured every 7days after treatment for 7 weeks. Biological control of WFT by 25 individual adults of O. laevigatus and Banker plant with 25 eggs of O. laevigatus were applied 1 time and resulted in the high control value of thrips 91.8%. The population of WFT was kept under the economic threshold level (1 individual per plant). For the last three years we developed new banker plant system. This system is being developed to improve biological control of WFT on chrysanthemums.
