[Results] All these three kinds of biological medicaments can control S. fasciata Butler in Q. mongolica, but the controlling effects are different from medicaments and dosage to medicaments and dosage. [Conclusions] The results indicated that control effects of avermectin 1.8% EC are faster than 8000 IU Bacillus thuringiensis and chlorbenzuron25% SC, it was the first choice for the pest occurrence of lage areas; the effects of 8000 IU B. thuringiensis were slow but very good; while the effects of chlorbenzuron 25% SC were poor.
