Thiamethoxam is considered a second generation of neonicotinoid insecticide, widely used in a variety of crops in Brazil and worldwide. Like other nenicotinoids, its toxic effect on the health of pollinating agents has been widely described in the literature and associated with the effects of disorders observed throughout the population, with harmful consequences for agriculture and especially for the survival of the species. The present project aims at the environmental risk assessment of Apis mellifera and Tetragonisca angustula species exposed to thiamethoxam and determination of this insecticide in samples of strawberry pollen and bees. The chemical determination will be optimized using the QuEChERS methodology and LC-MS / MS analysis. The toxic effects will be investigated from acute and chronic exposure, involving different stages of development of bees (adult and larvae) and use of biomarkers of exposure. Palynological analyzes of T. angustula's food preferences will confirm the risk associated with strawberry crops. The risk characterization will then be determined from the risk quotient (QR) calculated from data obtained in this study (determination and toxicity). Thus, it is hoped to contribute to the scientific knowledge involving the impact of this insecticide on the species investigated and the possible adoption of mitigating measures in case of confirmed environmental risk.
