D. Rugg et al., FIELD EFFICACY OF AN IVERMECTIN JETTING FLUID FOR CONTROL OF THE SHEEP BODY LOUSE BOVICOLA (DAMALINIA) OVIS IN NEW-ZEALAND, New Zealand Veterinary Journal, 43(2), 1995, pp. 48-49
The efficacy of an ivermectin jetting fluid against the sheep body lou
se, Bovicola (Damalinia) ovis, in long-woolled sheep was investigated
in three field trials. In all trials, louse populations in hand-jetted
sheep were reduced to nondetectable numbers within 2 weeks of treatme
nt. By comparison, shorn and unshorn control sheep maintained detectab
le infestations for the duration of the trials.
