Conteúdo: 	Toxic bait formulations have been one of the main strategies used in apple orchards in southern Brazil for the
control of South American fruit fly. 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 Samaritá 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 Samaritá Tradicional® associated with spinosad showed
high toxicity, with LC50 values of 6.92 and 10.61 ng/&#956;L diet to P. emerina, and of 4.37 and 15.48 ng/&#956;L 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.
