Pasa assay for diagnosing insecticide resistance in the horn fly population in Rondonia. [PDF]

open access: yes, 2014
Knockdown (kdr) resistance is caused by a reduction in the sensitivity of the insectnnervous system to pyrethroids. Kdr resistance in field populations of horn flies can severely limit pyrethroid usefulness in fly control programs.
