Background of CYP6CM1vQ

As a neonicotinoid pesticide, imidacloprid kills insects by irreversibly binding to nicotinic acetyl choline receptors, heavily interfering with neuronal transmission which can kill an insect at high doses. Due to this high level of specificity however mechanisms of resistance have evolved, most notably in the whitefly, possessing this variant of CYP6CM1. Capable of hydroxylating the 5th carbon of imidacloprid faster than other variants, CYP6CM!vQ bestows a partially protective effect against imidacloprid for an organism harboring this gene [1].
