Abstract  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.
