In vitro inhibition of glutathione S-transferases by several insecticides and allelochemicals in two moth species
International Journal of Pest Management 60 (1), 33-38
Abstract: Glutathione S-transferases (GSTs) are important detoxification enzymes in insects. This study examined the inhibitory effects of five insecticides (beta-cypermethrin, fenpropathrin, phoxim, abamectin, acetamiprid) and two plant-derived allelochemicals (quercetin, tannic acid) on GST activity in Micromelalopha troglodyta (Graeser) and Clostera anachoreta (Fabricius). GST activities were suppressed by all the insecticides and allelochemicals tested; the two allelochemicals were the most potent inhibitors, reducing GST activity in vitro in a dosage-dependent manner. Kinetic analyses of GST inhibition by quercetin and tannic acid in M. troglodyta and C. anachoreta suggested biochemical differences in their GSTs.
