Differential diagnosis of three common Ixodes spp. ticks infesting songbirds of western Europe : Ixodes arboricola, I. frontalis and I. ricinus
The three most common Ixodes spp. ticks found on songbirds in Western Europe are Ixodes
frontalis, I. arboricola and I. ricinus. As the latter species is a generalist, it shares several
avian hosts with the two strictly ornithophilic species. Infestations of the three species can
overlap in time and space, implying that tick-borne pathogens maintained by the ornithophilic
ticks and their hosts could be bridged by I. ricinus to non-avian hosts. Whereas the
endophilic Ixodes arboricola only occurs in cavities, I. frontalis has been collected frequently
by flagging methods from understory vegetation, which is also the habitat of the fielddwelling
I. ricinus. As the latter two species have rather similar morphological
characteristics, they can easily be confused with each other. In this study, we present
scanning electron photomicrographs of all developmental stages of I. arboricola and I.
frontalis, and provide a differential diagnosis key to distinguish the ornithophilic ticks from I.
ricinus. In addition, we interpreted their phylogenetic associations based on mitochondrial
16S rDNA with other Ixodes spp. ticks (I. lividus, I. turdus, I. brunneus, I. vespertilionis, I.
trianguliceps, I. hexagonus, I. scapularis).Fund for Scientific Research –Flanders (FWO)http://www.elsevier.com/locate/ttbdishb201

Bayesian cluster analysis.
<p>A: <i>ΔK</i> (a measurement of the rate of change in the structure likelihood function) values as a function of <i>K</i>, the number of putative supercolonies. In this case, <i>K</i> = 2. B: Graphical representation of the data set for the most likely <i>K</i> = 2, where each colour corresponds to a suggested cluster and each individual is represented by a vertical bar. The populations are indicated in the <i>X</i>-axis (AK: Akok; CA, CB and CC: Campo Forest Reserve; YM, YN, YS and YU: Yaoundé and its periphery). The <i>Y</i>-axis represents the probability for which an individual will be assigned to each cluster.</p
