AbstractCnaplocrocisednalisisorantstfetigiceodtio，tlarifefieldctroltofdientds CnaphalocrocisdlisspptedhicalstdsopsidfeldpetCaalocisalse results showed that the field efficacy of 150g/L indoxacarb SC had excellent preventive effect against Cnaphalocrocis medinalis，with the insecticidal effect and leaf preservation effect are above 90% at 7and 14d afterspraying the pesticides.The insecticidal effect and leaf preservation effect of 35% chlorantraniliprole WG and 10% tetrachlorantraniliprole SC were above 80% at 7 and 14 d after spraying. The field efficacy of 5% emamectin benzoate ME in biopesticides was the best，followed by 25% spinetoram WG，and these two pesticides had a slightly poorer effct on leaf preservation compared with indoxacarb，but the insecticidal effct were more than 90% . The insecticidal and leaf preservation effects of 20% spinoasad SC and 5% avermectin EC were also above 80% at 7 and 14d after spraying，whereas 8 000 IU/ μl of Bt SC was slightly less efective against Cnaphalocrocismedinalis in the field.In conclusion，except for Bt ，the field efficacy of the selected biopesticidesagistCaplococisedinlisisompabletatfcalpstidditiscoeddattab alternately and in rotation with indoxacarb for the field control of Cnaphalocrocis medinalis.
