Descrição: dc.descriptionAmong the more than twenty thousand bee species currently described, Apis mellifera stands out for its high economic relevance due to crop pollination. In recent decades, many studies have registered a decline in bee populations associating multiple factors, including pesticides. These molecules can arrive through residues present in the nectar and pollen, which can be ingested by the larvae. However, studies that contemplate the effects of fungicides on larvae and adults are rare. Thus, the objective of the study was to evaluate the effects of the exposure to pyraclostrobin in the larval phase and verify the late effects in newly emerged bees. The larvae were subjected to repeated exposure (third to the sixth day of the bioassay). The concentrations of pyraclostrobin consumption were 127.58 ng/larva (PT1), 13.16 ng/larva (PT2), and 4.24 ng/larva (PT3), both based on residues found in the field like as pollen and bee bread. The effects on larval mortality, pupation, emergence and survival rates, and median lethal time of newly emerged worker bees were evaluated. We also evaluated cell death and chitin marking of the peritrophic matrix in the intestine of larvae and newly emerged bees. No adverse effects were observed on the post-embryonic development of the larvae and survival time of the newly emerged workers, showing tolerance to the fungicide. However, the intestine epithelium of larvae (PT1 and PT2) and adults (PT1) showed immunostaining for cell death and increased intensity of chitin marking in the peritrophic matrix, indicating a late effect of the pyraclostrobin fungicide. Thus, the ingestion of the fungicide in the larval stage can impair the bee development and the health and performance of the colony. In this perspective, studies that consider the effects of fungicides in the different stages of bee development are crucial for a better interpretation of the risks of exposure.-
