## Abstract Pyrethroid resistance in field populations of Australian __Helicoverpa armigera__ (Hübner) is primarily a consequence of the overproduction of esterase isoenzymes which metabolise and sequester pyrethroid insecticides. Biochemical studies have shown that pyrethroid‐resistance‐associated
A cDNA clone encoding a cytochrome P450 from H. armigera was used to examine the expression of two homologous cytochrome P450 mRNAs, one of which, CYP6B2, is probably involved in pyrethroid metabolism. The mRNA for CYP6B2 in particular can be induced up to tenfold by peppermint oil and the monoterpe
