Abstract

Bees are the main pollinators of both remnants of native areas as the main crops. However, the number of species and individuals per hive has decreased, which may be related to increased use of pesticides. The intense occupation of the environment by man and the consequent human activities have made the bees a group very susceptible to habitat loss and pesticide exposure. In addition to high concentrations of pesticides that lead to death of bees, low concentrations can cause behavioral changes that affect the entire functioning of the colony and hence its services to ecosystems and agricultural crops. Analyses of sublethal effects of pesticides are addressed in the procedures adopted in other countries to assess risks to bees. When the standard procedure is insufficient to determine the effect of a product, there are official the recommendation for the use of additional studies to provide data for the final judgment as to the level of toxicity thereof. Thus, simultaneous evaluations of waste in the bees and the flowers visited could provide new information, contributing to the evaluation of the effect of chronic exposure to low doses of bees of a chemical compound allowing the understanding of the processes by which bees are exposed to pesticides.
