An emulsifiable concentrate formulation of the synthetic pyrethroid insecticide deltamethrin was applied in a plunge dip, 3 weeks after shearing, to a group of 5 Merino sheep infested with sheep body lice, Bovicola ovis. Deltamethrin concentrations on the wool were measured at regular intervals between 1 and 98 days after treatment and were not significantly different (P > 0.05) between sites on the dorsal mid-line, upper or lower flank. Levels in the tip of the fleece were significantly greater than those in the base, indicating that there was little movement of deltamethrin down the staple as the wool grew. Most lice were killed after 20 h of exposure in vitro to wool samples collected between 1 and 28 days after treatment. However, many lice survived in samples containing a similar concentration of deltamethrin, but collected between 35 and 98 days after treatment. Numbers of lice surviving increased with the sampling time after treatment, suggesting that the bioavailability of the deltamethrin changed as the insecticide aged in the fleece. Some transfer of deltamethrin occurred from treated to untreated sheep. The levels of deltamethrin were higher in sheep placed in contact with the treated group at 14 days after treatment than in those which were in contact from 43 days after treatment.
