The results indicated that three pesticides,3.6% reinforced type bisuhap GR,3.6% normal bisultap GR and 8% cartap-phoxim GR can effectively control sugarcane borers, and the control effect of dead heart rate and borer pest rate of sugarcane plants were about 80% and 69%. The control effect of 5% phoxim GR,3.6% reinforced type bisultap GR and 5% phorate GR against residual Holotriehia ovata in the field was up to 80%. The five pesticides can be used as ahemative pesticides against sugarcane borers and Holotriehia ovata, and the best application dosage in the field should be about 60-90 kg/ha.
