Synthetic pyrethroid resistance in Haematobia irritans subsp. exigua (Diptera: Muscidae): knockdown-recovery observed, a new putative resistance-linked mutation detected, and a complete voltage-gated sodium channel gene transcript sequenced.

Abstract excerpt

Haematobia irritans subsp. exigua (Diptera: Muscidae), locally known as buffalo flies, are the costliest pest of cattle in Australia. Control of H. i. exigua is primarily through insecticides despite resistance to many control chemicals now confirmed. Elevated resistance to synthetic pyrethroids in Queensland H. i. exigua populations has been observed, which led to this study to investigate if new voltage-gated...
