Abstract

Since the diversity of bee species is significantly diverse in tropical and subtropical locations, discussions concerning the environmental risk reassessment of pesticides have increased over the past few decades. Pesticides have a significant negative impact on stingless bees, hence toxicity data is required to include them in the regulatory process of nations that host a variety of these species. The current study therefore assessed the sensitivity of three species of stingless bees exposed to the commercial formulation of the neonicotinoid thiamethoxam, evaluated the Median Lethal Concentration (LC50), estimated the Median Lethal Dose (LD50), and evaluated the Median Lethal Dose (LD50) (TMX).
