A bioassay suitable for the determination of dose responses of the sheep body louse, Damalinia ovis , to avermectins is described. The inclusion of wool/skin substrate resulted in approximately 90% survival of controls over the 48‐h test period. Ivermectin and abamectin were highly effective against D. ovis , and similar responses of pyrethroid‐susceptible and resistant strains indicated that there was no cross‐resistance to ivermectin.
