This study aimed to detect the incidence, seasonal variation, age susceptibility of domestic pigeon to P. canariensis as well as ultra-morphological and molecular identification of circulating species (spp.) in Egypt. To achieve this aim; different pigeon premises in El- Gharbia governorate were investigated to correlate the findings with environmental factors responsible for parasitism. A total of two hundred pigeons (100 squabs and 100 adult) were examined for the presence of P. canariensis. during the period from March 2020 to March 2021. The incidence of P. canariensis was 64% among the examined birds. Higher incidence was recorded in young squabs than adults. P. canariensis infestation was predominant in both summer and spring seasons. The pigeon fly is a medium to large sized, flat with a flattened head, thorax and abdomen with short sheathed palpi (twice longer than broad). The wings are characterized by weak posterior veins, which have five veins behind the costal vein. The molecular characterization of this fly using the COX I (GenBank accession No. MW853922) was revealed that 704 bp, which displayed as 99.78% identity with the COI gene of Pseudolynchia sp. In a conclusion, to manage the external parasitism; sanitation and cleanliness are essential. Deltamethrin (Butox, 12.5 %) is effective insecticides periodically used as spray to overcome ectoparasites infestations for both bird and surrounding environment.
