    Notes: Abstract Data collected from a longitudinal survey carried out over 2 years on four farms in western France were used to assess the incidence and infestation of Ixodes ricinus on rodents. Once a month, on each farm, 25 Sherman live traps were set in hedges bordering selected pastures. A total of 799 micromammals were examined, including Apodemus sylvaticus, Clethrionomys glareolus, Microtus agrestis, Microtus arvalis, and Crocidura spp. Larvae and nymphs of I. ricinus were found. Small numbers of Ixodes (Exopalpiger) trianguliceps were also recovered from each farm. The mean infestation rate of the I. ricinus larvae (1.6–5.9) among all animals examined varied between farms Most animals were infested by only a single tick, but one M. agrestis harboured 43 I. ricinus larvae. Larvae or nymphs were found throughout the year, with peaks from March to October.

    Sites of attachment and density assessment of female Ixodes ricinus (Acari: Ixodidae) on dairy cows (1994)
    Springer
    Experimental and applied acarology 18 (1994), S. 681-689

    Notes: Abstract A sample of 110 lactating dairy cows was examined to describe the attachment sites of female Ixodes ricinus ticks and to assess whether counts on one or two body areas can predict infestation and its level. Seventy per cent of the cows were infested by I. ricinus and the average tick burden on the infested cows was 15, ranging from 1 to 136. Preferred attachment sites were the axilla, udder/groin, neck, dewlap and flank. Udder/groin and axilla carryied respectively 35.3% and 44.1% of the total tick burden. To predict infestation (yes/no), sensitivity of counts on axilla, on udder/groin and on both areas was respectively, 76.6%, 80.6% and 94.8%. Total burden prediction equations based on count on axilla and udder/groin are presented.

    Seasonal incidence and ecology of the tick Ixodes ricinus (Acari: Ixodidae) on grazing pastures in Western France (1995)
    Springer
    Experimental and applied acarology 19 (1995), S. 211-220 
    Details
    ISSN: 1572-9702
    Keywords: Ecology ; ticks ; Ixodes ricinus ; France

    Notes: Abstract A longitudinal survey was carried out during a 2 year period in Western France to assess the infestation level of grazing pastures byIxodes ricinus ticks. Four farms were visited once a month and each of the grazing pastures was sampled in the centre and at the border using the blanket dragging method. A total of 3562I. ricinus (34 adults, 900 nymphs and 2628 larvae) were collected and the infestation was significantly higher during the first year (p〈0.0001). The infestation level byI. ricinus varied between grazing pastures and farms. Grazing pastures in the vicinity of forest were more infested than the others, all through the study. The seasonal distribution of ticks showed peaks, with low fluctuations between farms, years and stages. Tick abundance could not be related to vegetation, but only to the vicinity of woods.
