Abstract: A 2-year study was conducted from March 2010 to March 2012 in a forested area in southern Italy to evaluate the species diversity and abundance of free-living ticks in 3 different habitats: (i) a meadow habitat within an enclosure inhabited by roe deer (Capreolus capreolus); (ii) a man-made trail located in a high-altitude, forested area; and (iii) a grassland near a house inhabited by 3 people. In total, 10,795 ticks were collected. Ixodes ricinus was the most abundant species (69.0%), followed by Haemaphysalis inermis (19.1%), Rhipicephalus turanicus (6.7%), Dermacentor marginatus (3.2%), and Hyalomma marginatum (1.0%). The least frequently collected species were Rhipicephalus bursa, Haemaphysalis parva, Haemaphysalis sulcata, and Haemaphysalis concinna, representing together less than 1% of the collections. Immature ticks predominated over adult ticks. In particular, immature stages of Ix. ricinus (i.e., 3246 larvae and 3554 nymphs) represented 63% of the total number of ticks collected. High levels of species diversity and abundance of ticks were recorded in all habitats and the daily number of ticks collected was negatively correlated with daily mean temperature, evapotranspiration, and saturation deficit. This study indicates that the southern Italian climate is suitable for different tick species, which may find a preferred 'climate niche' during a specific season, when a combination of factors (e.g., suitable meteorological and environmental conditions) associated with the presence of suitable hosts will facilitate their development and reproduction.
