Here, we examined the in vitro effects of co-exposure to a pathogen and a common neonicotinoid on honey bee larvae survival and on adult learning behavior following a standard olfactory conditioning procedure based on the proboscis extension response paradigm. We exposed or co-exposed honey bee larvae to American foulbrood and to sub-lethal doses of thiamethoxam (chronic exposure). Our results revealed no additive effects between the two stressors on larval mortality. However, the present work provides the first evidence of impaired learning and memory in adult bees that were fed thiamethoxam (0.6 ng/bee) during the larval stage. We also show no alterations in learning and memory in bees after infection with American foulbrood at the larval stage. The present study contributes to our knowledge of the sub-lethal effects of neonicotinoids on honey bee larvae and adults.
