For a better evaluation of the model using Apis mellifera in toxicology studies with insecticides, the oral acute toxicity of the insecticide fipronil against the stingless bee Melipona scutellaris was determined. The results showed that fipronil was highly toxic to M. scutellaris, with a calculated LC(50) (48 h) value of 0.011 ng a.i./μL of sucrose solution and an estimated oral LD(50) (48 h) of 0.6 ng a.i./bee. Our results showed that M. scutellaris bee is more sensitive to fipronil than the model specie A. mellifera.
为了更好地评估利用蜜蜂进行杀虫剂毒理学研究的模型，测定了杀虫剂氟虫腈对无刺蜜蜂 Melipona scutellaris 的口服急性毒性。结果表明，氟虫腈对 M. scutellaris 具有高毒性，计算得到的 LC (50)（48 h）值为 0.011 ng a.i./μL 蔗糖溶液，估计口服 LD (50)（48 h）值为 0.6 ng a.i./蜂。我们的结果表明，无刺蜜蜂 M. scutellaris 比模型物种 A. mellifera 对氟虫腈更为敏感。
