This study examines the susceptibility of the honey bee to the commercial neonicotinoids, related compounds in commercial development and potential metabolites. Studies were also included to examine the practical use of neonicotinoids and fungicides in combination and their effect on honey bees. When honey bees were placed in cages in forced contact with alfalfa treated with acetamiprid and the synergist, triflumizole, in combination at their maximum recommended application rates, no mortality was detected above that of the control. Cage studies where acetamiprid and triflumizole were applied in combination to alfalfa at the maximum recommended rate, no bee mortality was detected, suggesting that certainly acetamiprid alone and even acetamiprid in combination with a potent P450 inhibitor, is safe to honey bees.
