Thiacloprid

Thiacloprid is an insecticide of the neonicotinoid class. Its mechanism of action is similar to other neonicotinoids and involves disruption of the insect's nervous system by stimulating nicotinic acetylcholine receptors. Thiacloprid was developed by Bayer CropScience for use on agricultural crops to control of a variety of sucking and chewing insects, primarily aphids and whiteflies.

Thiacloprid has been banned in France since September 1, 2018. The 5 neonicotinoids banned in France are Acetamiprid, Clothianidin, Imidacloprid, Thiacloprid and Thiamethoxam.

Thiacloprid, as active substance and as formulation, poses a substantial risk to honey bees by disrupting learning and memory functions. Honey bees (Apis mellifera carnica) were exposed chronically to thiacloprid in the field for several weeks at a sublethal concentration. Foraging behavior, homing success, navigation performance, and social communication were impaired, and thiacloprid residue levels increased both in the foragers and the nest mates over time. Thiacloprid exposed free-flying bumblebee colonies were more likely to die prematurely, and those that survived reached a lower final weight and produced 46% fewer reproductives than colonies placed at control farms.

D. Beneficial Insects:. Based upon the results of core bee toxicity tests, it is predicted that thiacloprid will not adversely affect bees. In addition, thiacloprid toxicity is unlike other neonicotinoid insecticides (i.e.: imidacloprid, and clothianidin) which have demonstrated very high to high acute toxicity to bees. (p. 10)
