Cephenemyia stimulator (Diptera) infection in roe deer (Capreolus capreolus) from Kraków area, southern Poland.

UNLABELLED: The aim of the study was to determine the prevalence of botfly (Diptera: Oestridae) larvae infection in roe deer populations (Capreolus capreolus) in the Kraków area on the basis of necropsy and questionnaire surveys. Hunters were surveyed about the age and sex of hunted animals, and the origin of their habitat. All parasite specimens were identified to species in the laboratory. The parasites were found in the nasal cavities, esophagus, and larynx of male roe deer aged 3-8 years, living in forest habitats. The level of infection was relatively low (13%), with the intensity ranging from 1 to 10 larvae per host. Although no fly larvae were found during the dissection of roe deer carcasses, the parasites received from the hunters were identified as Cephenemyia stimulator botflies. These findings are supported by the evidence drawn from the questionnaires completed by the hunters. KEY WORDS: parasites, Cephenemyia stimulator, Capreolus capreolus, necropsy, questionnaire study, Poland.
