摘要: 目的:了解啶虫脒对大别山散白蚁的毒性,为开发新的白蚁防治药物提供依据。方法用滤纸浸药液法和点滴法处理试虫,定时观察试虫的中毒、死亡情况。结果啶虫脒对大别山散白蚁作用速度较慢,处理后144h具最大毒效,但大别山散白蚁对啶虫脒药剂非常敏感,24h时LD50值仅为7.00×10-5μ/g虫。结论啶虫脒对大别山散白蚁的毒杀效果良好,其控制白蚁作用值得进一步研究。

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.
