According to the results obtained, by using the SSS tributyl phosphotritiade sinergist (DEF) and piperonyl butoxide, it was demonstrated that the multiple function esterases and oxidases played an important role in the resistance to temephos and fenthion.
It was proved that he amplified activity of these enzymes was at an elevated frequency in both people's councils, the same as the glutathione transferase (GST) in one of the 2 people's councils.

A dependence on cytochrome P450 was shown by a requirement for NADPH and inhibition by carbon monoxide, 1-aminobenzotriazole, piperonyl butoxide, and stiripentol.
The addition of glutathione transferases diminished protein adduct formation beyond that seen with glutathione alone.

Larvae and adults of this strain manifest approximately 50-fold resistance, which is suppressible by piperonyl butoxide and controlled by the semidominant gene RFen1 previously mapped to AFLP Linkage Group 13.
Two cytochrome P450s (CYP337B1 and CYP4S1), one carboxylesterase-like protein and one glutathione transferase were found to be constitutively upregulated in resistant insects.

Addition of piperonyl butoxide or SKF 525-A to hepatic microsomal incubations markedly decreased covalent binding of naphthalene metabolites but only slightly decreased glutathione adduct formation.

The microsomal reaction was dependent on NADPH and oxygen and was inhibited by cytochrome P450 inhibitors such as metyrapone, 2-diethylaminoethyl-2,2'-diphenylvalerate (SKF 525-A), alpha-naphthoflavone and piperonyl butoxide.
