Including the synergists piperonyl butoxide, a cytochrome P-450 monooxygenase inhibitor, or S,S,S-tributylphosphorotrithioate, an esterase inhibitor, in the methiocarb bioassays partially suppressed resistance in the most resistant populations.

The participation of P450 and FMO in the sulfoxidation of four sulfur containing peptides, ametryne; terbutryne, prometryne and methiocarb was investigated using human liver microsomes.

The sulfoxidation of the thioether pesticides, phorate, disulfoton, sulprofos, and methiocarb, was investigated.

In addition cytochrome P450 (CYP) 1A activities in livers were induced by prochloraz, possibly as a result of Ah receptor activation.
The purpose of this study was to investigate reproductive toxic effects after exposure during gestation and lactation to prochloraz alone and a mixture of five pesticides (deltamethrin, methiocarb, prochloraz, simazine, and tribenuron-methyl).

3579305 Blee E, Durst F: Hydroperoxide-dependent sulfoxidation catalyzed by soybean microsomes. . Arch Biochem Biophys. 1987 Apr;254(1):43-52.

The sulfoxidation of methiocarb, an aromatic-alkyl sulfide pesticide, catalyzed by soybean microsomes was found to be strongly stimulated in the presence of cumene and linoleic acid hydroperoxides.
Our results seem to rule out the participation of cytochrome P-450 in this oxidation, whereas the studied sulfoxidase presents some similarities to plant peroxygenase.

The interactions between six insecticides (methiocarb, formetanate, acrinathrin, deltamethrin, methamidophos and endosulfan) and three potential synergists (piperonyl butoxide (PBO), S,S,S-tributyl phosphorotrithioate (DEF) and diethyl maleate (DEM)) were studied by topical exposure in strains selected for resistance to each insecticide, and in a susceptible strain of Frankliniella occidentalis (Pergande).
These studies indicate that an enhanced detoxification, mediated by cytochrome P-450 monooxygenases, is the major mechanism imparting resistance to different insecticides in F occidentalis.
