Kdr resistance and determination of frequences of kdr gene in house fly field population L1014F is the most common amino acid substitution in the kdr allele. The frequency of the L1014F kdr allele was determined by the method of PASA in fourteen field populations of houseflies with resistance factors at LD��� for pyrethrin/ piperonyl butoxide and bioresmethrin/piperonyl butoxide from 4 to 29 and 2 to 98, respectively.
