Abstract: Objective To determine the toxicity of acetamiprid against Reticulitermes dabieshanensis so as to provide the theoretical basis for developing new termiticides.Methods Two methods were applied in this study.One method was to dip the filter paper in the different concentrations of acetamiprid solution,and then put in the Petri dish padded moistened sands.Then 30 Reticulitermes dabieshanensis were introduced into the Petri dish,and the mortality was recorded every 24h.For the other method,Reticulitermes dabieshanensis individuals were treated by topical method with different concentrations of acetamiprid.Then the treated individuals were introduced into Petri dish with moistened sands in the bottom,and the mortality was recorded in certain times after treatment.Results Active speed of acetamiprid against Reticulitermes dabieshanensiswas low,the best toxic effects occurred at 144 h after treatment.But Reticulitermes dabieshanensis was rather susceptive to acetamiprid,the LD₅₀at 24 h was only 7.00×10^-5μg/termite.Conclusion Acetamiprid has a good toxic efficacy to Reticulitermes dabieshanensis,its possibility for termite control in practice deserves further study in the near future.
