Effectiveness of Beauveria bassiana ERL as entomopathogenic fungi against thrips pupae were evaluated on greenhouse cucumber(bumnong backdadagi), rose(Affinity) respectively. Control efficacy was calculated by the formula, (Dcontrol - Dtreatment)/Dcontrol x 100, where Dcontrol is the average density of thrips on the plots in which any pesticides and entomopathogenic fungi was not relesed and Dtreatment is the average density of thrips on the plots in which entomopathogenic fungi were released respectively. As a result, control efficacies of Beauveria bassiana ERL 10^7 cfu/g treatment against thrips on cucumber was 89.4~91.3%, respectively. In addition, control efficacy of Beauveria bassiana ERL 10^8 treatment against thrips on cucumber was 92.0~93.2%. Also, control efficacies of Beauveria bassiana ERL treatment against thrips on cucumber was 61.5-69.2%. Thus, even thrips control flow that occurs in the solanaceae vegetables thrips current period is officially Beauveria bassiana ERL 10 ^ 7 to effective treatment cfu / g, pepper and tomato cucumber and rose to occur will be effective. These results demonstrate the promise of entomopathogenic fungi, especially Beauveria bassiana ERL for management of thrips pupae. In addition to thrips control that is occurring in the solanaceae vegetables such as peppers and tomatoes will be effective.
