title: Efficacy of alphacypermetrin pour-on against natural Werneckiella equi infestation on donkeys (Equus asinus).
abstract: The chewing louse Werneckiella equi is an ectoparasite of donkeys and other equids. Alphacypermethrin (ACYP) is a pyrethroid insecticide commonly used for the control of insects of veterinary and public health concerns. A trial was conducted to assess the efficacy of ACYP against W. equi on naturally infested donkeys. Parasitological investigations were performed on 13 animals. On day 0, the donkeys received ACYP pour-on at the manufacturer's recommended dose rate for cattle. Louse counts were performed on days -1, 7, 14, 21, 28, 35, 42, 49, and 56 at seven predilection sites on the skin of each donkey. ACYP was completely effective (100 %) from day 7, until the end of the study. ACYP was well tolerated by all animals as there were no observed clinical adverse reactions. ACYP was highly effective, safe, user-friendly, and considered to be suitable for the treatment of donkeys for W. equi infestation.
