Abstract: The rice leaf-folder(Cnaphalocrocis medinalis Guenee) 3rd instar larvae were treated with 5 buproferin concentrations. The results indicated that buprofezin had no effects on moth emergence rate and egg production, but moth emergence peaks were delayed by 1 day. The egg hatch rate, survival rates of egg-2nd instar larvae and 2nd-5th instar larvae were significantly decreased with the concentration increasing.
