An investigation was performed to compare the efficacy of some insecticide drugs for control of mallophagosis in chickens. In this trial, 24 chickens at the age of 4 months were used that were experimentally infected with chewing lice from the following species: Menopon gallinae; Eomenacanthus stramineus; Menacanthus cornutus (Amblycera) and Goniocotes gallinae (Ischnocera) randomly alloted to three experimental and one control groupa. The birds from experimental groups were treated with one of the following insecticid preparations: 0.1% solution of Ectomin 100EC, Ciba Geigy (100 g/l cypermethrin); Tapilan B, Dorvet Ltd (2% permethrin) and Bolfo Puder, Bayer Health Care(1% propoxur). The intensity of infection was determined at post treatment hours 2, 4 and 6 on the day that followed the treatment and subsequently once weekly for one month after the antiparasitic treatment of experimental groups. As early as the 6th post treatment hour, the lice infection was eliminated in all treated groups and this result was retained until the end of the experiment. The results showed that the single treatment at proper doses with the preparations containing the insecticide substances cypermethrin, permethrin and propoxur, removed completely the infection with chewing lice in chickens.
