Background and Aim: Biting lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites that play important roles in the transmission of disease agents that infect turkeys and impact turkey productivity. This study aimed to determine the diversity of lice that infest turkeys in the Central Java Province and the Special Region of Yogyakarta, Indonesia.

Materials and Methods: Lice sampling was conducted at 16 different locations from April 2019 to June 2019 in turkeys aged 4 months to 2 years. The samples were stored in 70% alcohol and were identified using avian louse keys. The morphology of the specimens was macroscopically and microscopically evaluated, and the resulting data were descriptively and qualitatively analyzed.

Results: A total of 2505 lice were collected, and two families and five genera of lice were identified. Three lice genus members of the Philopteridae family (Lipeurus, Oxylipeurus, and Chelopistes) and two genera of the Menoponidae family (Colpocephalum and Menacanthus) were identified. Lipeurus was the most frequently identified genera in turkeys, whereas Menacanthus was the most rarely identified one. The White Holland breed had the highest number of lice infestations, whereas the Jersey Buff breed exhibited the highest diversity of lice genera. The average number of lice infestations was higher in male turkeys than in female turkeys.

Conclusion: The occurrence of ectoparasites in domestic turkeys indicates that the existence and diversity of lice genera in the study location can be influenced by turkey type, turkey maintenance system, enclosure sanitation measures, lack of strategic ectoparasite control, and environmental factors.
