Fipronil is an insecticide widely used to control a great number of pests, thus the aim of this study was to determine the lethal dose and lethal concentration (LD50 and LC50) of this insecticide to the stingless bees Scaptotrigona postica Latreille, 1807. The LD50 and LC50 values obtained after 24 h of exposition were of 0.54 ng a.i./bee and 0.24 ng a.i./mu L diet, respectively. These values were considered highly toxic to stingless bees.
