Abstract

Spinosad is a new insecticide which shows obvious activity against Cnaphalocrocis medinalis Guenee. The results of toxicity determination by leaf-dipping method in laboratory indicated that LC50 of spinosad was 0.066 8 mg/L to 3 rd instar larvae of Cnaphalocrocis medinalis. The result of control tests in fields showed that 2.5% spinosad SC had the better effect on the controlling of elder instar larvae, the efficacy was 65.51% to 86.80% after 1 day, the efficacy was 76.26% to 89.47% after 5 days. 2.5% Spinosad SC was safe on rice and its influence to natural enemy was little.
