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.

Honey bees (Apis mellifera carnica) were exposed chronically to thiacloprid in the field for several weeks at a sublethal concentration.

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.Thiacloprid; Pesticide Tolerances: A Rule by the Environmental Protection Agency on 02/06/2013 federalregister.gov Pesticide Fact Sheet Name of Chemical: ThiaclopridReason for Issuance: Conditional RegistrationDate Issued: September 26, 2003 www3.epa.gov D.
