| the treatment and eradication of sheep lice and ked with cyhalothrin--a new synthetic pyrethroid. | a new synthetic pyrethroid, cyhalothrin, has been evaluated as both a sheep dip and a jetting fluid for the control of body lice (damalinia ovis), face lice (linognathus ovillus), foot lice (linognathus pedalis) and the sheep ked (melophagus ovinus). a dip wash concentration of 1.25 ppm cyhalothrin eradicated d. ovis from sheep. a jetting fluid at a concentration of 20 ppm also eradicated d. ovis. in the field cyhalothrin was evaluated at 20 ppm as a dip wash and at 50 ppm as a jetting fluid. th ... | 1984 | 6534357 |
| ectoparasites of sheep in three agro-ecological zones in central oromia, ethiopia. | a cross-sectional study was conducted to determine the prevalence and risk factors for ectoparasites infestation in sheep in three agro-ecological zones in central oromia, ethiopia, from october 2009 to april 2010. the study revealed that 637 (48.1%) of the 1325 sheep examined were infested with one or more ectoparasites. the ectoparasites identified were bovicola ovis (27.2%), melophagus ovinus (16.4%), ctenocephalides sp. (2.3%), linognathus africanus (1.2%), linognathus ovillus (0.3%), sarcop ... | 2012 | 23327319 |
