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.},

The trials included 7632 sheep with 3-9 months wool growth. Louse counts were obtained periodically from 23-25 monitor sheep selected from each treated flock for up to 15 weeks after treatment. Overall reductions in louse counts at 4-6, 8-10, 11-13, and 15 weeks after treatment compared with pretreatment values were 98.7, 99.0,98.9, and 99.8\%.},

	abstract = {<p>We investigated the role of monooxygenases in resistance to synthetic pyrethroids (SPs) in the cattle tick, Boophilus microplus. We found that monooxygenases play only a minor role in resistance to SPs in both resistant and susceptible strains of B. microplus. We blocked the monooxygenases with piperonyl butoxide (PBO) and simultaneously applied the SPs, flumethrin and cypermethrin to larval B. microplus. PBO increased the effect of flumethrin (synergism ratios 2.7-8.9) more than it increased the effect of cypermethrin (synergism ratios 1.9- 3.1). Of the four strains tested, Parkhurst, which is resistant to SPs, was the least affected by the addition of PBO (synergism ratios after cypermethrin was applied 1.9; after flumethrin 2.7) whereas N.R.F.S., the strain susceptible to SPs, was the most affected by synergism between PBO and SPs (synergism ratio after cypermethrin was applied 3.1; after flumethrin 8.9). We hypothesize that B. microplus lacks monooxygenases capable of conferring resistance to SPs because it and its recent ancestors were blood-feeders rather than herbivores.</p>
