Abstract

We determined the infestation rates of larvae from two species of Warble Fly (Hypoderma diana and Hypoderma actaeon) on red deer (N=388) and roe deer (N=361) carcasses obtained in North-North-West Hungary (Szigetköz, District of Ravazd and Tarján) from October 2017 to February 2020. Of the total 28,584 Hypoderma Warble Fly larvae, counted on both deer species, were identified as H. diana (62% of total) and H. actaeon.(38% of total). Approximately 74% of the red deer and 79% of the roe deer were infested with either or both species. Red deer contained 17,717 and 10,867 larvae of H. diana and H. actaeon respectively. Of the 17,717 larvae of H. diana, 42% were found in red deer and the remaining 58% in roe deer. Of the 10,867 larvae of H. actaeon, 87% were found in red deer and the remaining 13% in roe deer. We interpreted our results in terms of QP 3.0 parasitological analysis and the need to map the spread of this serious parasitic infestation.
