Thiacloprid is a neonicotinoid insecticide that acts as a selective agonist at insect nicotinic acetylcholine receptors (nAChRs) with IC₅₀values of 2.7 and 860 nM forDrosophilanAChRs and M10 mouse fibroblast cells expressing α4β2 subunit-containing nAChRs, respectively.¹It is active against aphids, whiteflies, various species of beetle, andLepidopteraspecies when used at concentrations ranging from 48 to 180 g AI/hectare.²It has anti-estrogenic activity in a yeast estrogen screen and is toxic to adult female houseflies and mice (LD₅₀s = 0.03 and 28 mg/kg, respectively).^1,3Formulations containing thiacloprid have been used in the control of insects in agriculture.
