High biological activity is observed for the sulfide, sulfoxide, sulfone, and desulfinyl derivatives in both the ethiprole and the fipronil series in GABA receptor assays (human recombinant beta3 homomer and house fly head membranes) with [(3) H] EBOB and in topical toxicity to house flies with and without the P450-inhibiting synergist piperonyl butoxide.

Fipronil, an N-phenylpyrazole with a trifluoromethylsulfinyl substituent, initiated the second generation of insecticides acting at the gamma-aminobutyric acid (GABA) receptor to block the chloride channel.
The P450 inhibitor piperonyl butoxide, acting in houseflies, increases the metabolic stability and effectiveness of fipronil and the sulfone but not those of the desulfinyl compound, and in mice it completely blocks the sulfoxide to sulfone conversion without altering the poisoning.

We conclude that dieldrin resistance in the An. gambiae population of the Obuasi region occurs at a high level - most likely in the absence of selection - and that control of the resistance phenotype is polyfactorial and must include components other than mutations in the GABA receptor locus.
