Technical Abstract: Since the market introduction of imidacloprid, neonicotinoids have become the fastest growing class of insecticides. Neonicotinoid treated seeds give rise to plants that are protected from pests throughout the plants entire life. The plant can metabolize the neonicotinoid through all parts of the plant, including its pollen and nectar. When non-target insects such as honey bees forage on these plants they are bringing contaminated resources back to their nest for consumption. With respect to the male bees (drones), the effects of dietary thiamethoxam on their physiology and behavior has very understudied. Drones participate in mating flights with virgin queens. Since a drone’s only role is reproduction, the ability to fly and navigate to the mating congregation area (MCA) is critical for successful mating. If neonicotinoids interfere with the ability of a drone to find and navigate to the MCA, then reproduction has been disrupted before it can even take place. The overall loss of drones due to an impaired ability to navigate and or control motor function if it reaches the MCA, can lower the genetic diversity of colonies and thus impact the future success of a colony. This study aims to assess the impact of thiamethoxam on drone navigation and motor function that it will significantly affect the overall colony health and fitness.
