Important note

In 2015, six Dermacentor ticks were collected in SE-Luxembourg. Previously, these individuals had been identified as Dermacentor marginatus Leach, 1815. However, morphological re-investigation as well as DNA barcoding identified the specimens as Dermacentor reticulatus (Fabricius, 1794). Thus only D. reticulatus is known from Luxembourg (Weigand et al. 2020).

Brief description

Dermacentor marginatus Leach, 1815 is a species of tick of the family Ixodidae, which is a vector of several zoonotic diseases, which is why this tick is considered to pose particular eco-epidemiological and public health risks for humans (Wikipedia contributors 2019).

In Central Europe the sheep tick is the most common species of the genus. It lives here only in heat islands and on sunny slopes or dry grasslands. Mammals, including humans, are preferred as hosts. The animals of the genus transmit tularemia (Francisella tularensis), Rocky Mountain spotted fever (Rickettsia richettsii), Q-fever (Rickettsia burneti), bovine anaplasmosis, puppy-babesiosis (Babesia canis) (Source: http://www.ijon.de/zecken/system.html#zecke).

It is one of the species that could be favoured by global warming, which would allow it to move northwards, but also upwards (Wikipedia contributors 2019).

Status and distribution in Luxembourg

The tick Dermacentor marginatus Leach, 1815 is absent from Luxembourg.

Risk assessment

ISEIA protocol

Following the morphological re-investigation as well as DNA barcoding that identified all the specimens as Dermacentor reticulatus (Fabricius, 1794) (Weigand et al. 2020), Dermacentor marginatus is considered absent from Luxembourg and was reassessed on 29 October 2020 to C0 (2+1+2+1). Initial assessment: C1 (2+1+2+1) (Ries et al. 2017: 68).

Harmonia+ protocol
