EXAMINATION OF NASAL BOTFLY (CEPHENEMYIA STIMULATOR,CLARK, 1815) OF ROE DEER

Abstract

Abstract- Parameters of nasal botfly infestation of roe deer in plain locations

I am investigating the occurrence of one of the diseases caused by parasites in plain roe deer populations, namely a botfly larvae, Cephenemyia stimulator, (CLARK, 1815) ranged among the Oestridae family. Nasal botfly larvae are common roe deer parasites and aregenerally spread nationwide. The subject of the present survey is the processing of the data gained about roe deer bucks of the year 2009 and their infestation indices. I investigated botfly larvae in 75 bucks’ nasal andpharyngeal cavity. We have found botfly larva in 17,3% of the examined bucks (prevalence), this means 13 infected specimen. I collected 199 pieces of larvae from the samples, with a 15,3 pieces mean intensity. In our  investigations prevalence was lower than in previous Hungarian researches. This was manifested both in our overall data, and in our examinations by the different age groups. The rate of infestation was demonstrably higher in the old age group. This can be explained by the territorial behaviour of the roe deer, which can also be manifested by the older bucks’ displacement to weaker habitats.
