Indoor Toxicity Determination of Several Pesticides to Ceratovacuna lanigera （Zehntner）

摘要

Toxicity of 96% chlorpyrifos TC,98% imidacloprid TC,98% thiamethoxam TC and mixed pesticides of chlorpyrifos with other two agents( D + B,D+ S) to C. lanigera( Zehntner) were determined under laboratory conditions by leaf dipping method. The results showed that all of the pesticides had high toxicity with the order of thiamethoxam TC > imidacloprid TC > D + B > chlorpyrifos TC > D + S. The results provided theoretic basis for selecting suitable insecticides to control the C. lanigera( Zehntner).
