However, its effects on the stingless bees Plebeia emerina (Friese) and Tetragonisca fiebrigi (Schwarz) are unknown. This study aimed to assess the toxicity, attraction and repellency of food lures and toxic baits on P. emerina and T. fiebrigi. We evaluated the food lures Anamed?? (pure), Biofruit?? (3%), Flyral?? (1.25%), Sugarcane molasses (7%) and Samarit?? Tradicional?? (3%), in toxic baits formulations associated with spinosad (Tracer?? 480SC) and malathion (Malathion?? 1000EC), and the ready-to-use toxic baits Success?? 0.02CB and Gelsura??. We obtained the mean lethal concentration (LC50) and the mean survival of workers after exposure to toxic bait formulations. In the field, we carried out attraction and repellency tests of toxic baits to foraging. The food lures associated with malathion and spinosad showed different levels of toxicity to P. emerina and T. fiebrigi. Sugarcane molasses and Samarit?? Tradicional?? associated with spinosad showed high toxicity, with LC50 values of 6.92 and 10.61 ng/μL diet to P. emerina, and of 4.37 and 15.48 ng/μL diet to T. fiebrigi, respectively. Gelsura?? and food lures with malathion caused rapid workers mortality, with mean survival less than 3 h after exposure. No toxic bait formulation was attractive to P. emerina foragers in the field. Anamed??, Gelsura??, and Success?? were repellent to P. emerina foragers.  aAnastrepha fraterculus  aAttract and kill  abees  aFood lures  aMalus domestica  aPollinators Native1 aPIOVESAN, B.1 aMORAIS, M.
