| 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 |
