Effect of oral exposure to the acaricide pirimicarb, a new varroacide candidate, on Apis mellifera feeding rate

Résumé

Background: The ectoparasitic honey bee mite Varroa destructor is a main cause of the gradual decline in honey bees Apis mellifera. Beekeepers currently utilize a wide range of different synthetic acaricides, organic acids and essential oils to keep mite populations under control. Previous work has indicated that pirimicarb may be a new varroacide candidate. The aim of this study was to observe chronic effects on feeding activity in worker honey bees after oral exposure to 1.05 mm pirimicarb. The long-term effects of 24 h exposure to pirimicarb were also tested. Results: After three successive trials, no mortality could be detected at the tested concentration, although oral exposure to pirimicarb had a significant effect on honey bees feeding behavior. Pirimicarb added to a sucrose solution led to a rapid decrease in food intake. These tendencies may be reversed when the pesticide is removed. However, recovery seemed to be trial dependent. Conclusion: This study highlights seasonal variation in honey bee susceptibility, which should be considered in toxicology studies
