Sulfoxaflor Exposure Reduces Food Intake and Impairs Learning in Osmia Bicornis Bees

A study published in *Scientific Reports* indicates that exposure to the systemic insecticide sulfoxaflor reduces food intake and impairs learning capabilities in the solitary bee species *Osmia bicornis*. Researchers observed that the chemical alters fundamental behaviors in these insects, raising questions regarding the potential impact of the pesticide on solitary bee survival and population health.

The investigation measured how the bees responded to the insecticide under controlled conditions, focusing specifically on their foraging habits and cognitive performance. The data show that bees exposed to sulfoxaflor consumed less food than those in the control group and demonstrated a decreased ability to learn and retain information. These findings highlight a link between the use of the insecticide and behavioral changes in *Osmia bicornis*, providing new information on how chemical exposure influences the biological functions of solitary bee species.
