Abstract
The susceptibility to ivermectin of a highly selected pyrethroid-resis tant laboratory strain of the Australian sheep blowfly Lucilia cuprina was assessed in a payer-serum bioassay and compared with an organopho sphate-resistant field strain and a laboratory-susceptible strain. Whi le the pyrethroid-resistant strain has a resistance factor of > 3000-f old to deltamethrin, ivermectin was only 2.5-fold less toxic to this s train than it was to the other two strains. These results indicate tha t pyrethroid resistance is unlikely to affect the larvicidal activity of ivermectin in L. cuprina.
