α- naphthyl acetate: mMoles α-naphthol produced/min/mg protein. β- naphthyl acetate: mMoles β-naphthol produced/min/mg protein. p450: Equivalent units of cytochrome p450. GST: GST activity. AChE: average percentage inhibition of AChE by propoxur. a: those populations showing a significant difference, P < 0.001, to the DurbanS susceptible laboratory strain that may confer insecticide resistance.
