AbstractCollars impregnated with dichlorvos, naled, or stirofos on Persian cats for 10 weeks were ineffective against the cat fur mite, Felistrophorus radofskyi (Tenorio). Powders containing methoxychlor, carbaryl, or rotenone at dosages of 137-146 mg/kg applied to the fur once per week were also ineffective. When the dosage of the rotenone powder was increased to 293 mg/kg, 100% control resulted after 5 weeks of treatment. Mild adverse reactions occurred from the dichlorvos collar (salivation) and the rotenone powder at the higher dosage (depression and loss of appetite). The cat wearing the naled collar died after 9 weeks with signs that suggested organic phosphate toxicosis.
