Abstract

Abstract: The host switching of Hypoderma actaeon (Diptera: Oestridae), a specific parasite of red deer ( Cervus elaphus ), towards roe deer ( Capreolus capreolus ) has been recently reported in Spain. To provide information about the temporal and spatial spreading of H. actaeon infection in roe deer, 244 serum samples from animals hunted in Spain between 2013 and 2018 were analysed by an indirect enzyme‐linked immunosorbent assay. The overall seropositivity was 13.9%. Seropositivity was higher in continental (27.7%) and mountainous (12%) areas from central Spain, followed by southern‐Mediterranean (11.2%) and northern‐oceanic regions (3.5%). Differences were significant between central‐continental and northern‐oceanic regions ( P = 0.003). No differences were found according to the sex and age of roe deer ( P > 0.05). In 2013, all seropositive animals were concentrated in two distant areas in central and southern Spain, suggesting that the host switch could have occurred independently in both regions. Changes in the pattern of distribution of red deer and roe deer could have favoured the spreading of this myiasis towards roe deer, indicating that roe deer may become infested by H. actaeon in areas where both cervids coexist at high densities. Abstract : Changes in the distribution of cervidae have implications for warble fly infestations. The host switching of Hypoderma actaeon from red deer to roe deer in Spain could have occurred independently in two distant foci. The risk of being seropositive is higher in roe deer from central‐continental areas than in north‐oceanic ones.
