First data on identification of avian lice Ciconiphilus decimfasciatus (Boiduvale and Lacordaire, 1835). Species parasitizing Cattle Egrets (Bubulcus ibis) in Eastern of Algeria

This study was conducted to identify a Mallophagous louse in the cattle Egret (Bubulcus ibis) during the breeding season between 2015,2016 and 2017 in the eastern region of Algeria at several areas (Oum el Bouaghi area, the heronry of Silla common Sigus, and el Madher wilaya de Batna). During this period the chicks were examined macroscopically for lice. The detected lice were collected and then fixed with 70% ethanol in pillboxes. The lice were clarified in 10% KOH for 24hours, rinsed with distilled water, and dehydrated in ascending ethanol baths (70%, 80% and 99%). Finally the samples will be mounted on the slide and coverslip with Canada balsam. The identification was performed under binocular microscope Leica DM750. The identification of mallophagous lice of cattle egret (Bubulcus ibis) has shown that it is infected by a single species of mallophagous louse that is represented by Ciconiphilus decimfasciatus.
