摘要

The aim of this study was to investigate whether differences in Ixodes ricinus (L.) nymphal relative density exist among different vegetation types in southern Sweden. Nymphal L ricinus were sampled in southeastern Scania in southern Sweden during June-August 1997. A total of 110-18025-m(2) samples were taken by blanket-dragging from each of nine different vegetation types. There was a highly significant difference in nymphal abundance between the open areas as one group and the forested areas as another group (P < 0.0001). Vegetation types that differed significantly in median nymphal abundance from all other vegetation types were pine forest (16 nymphs/100 m(2)) and beech forest (40 nymphs/100 m(2)). No significant differences in median nymphal density were revealed among mixed deciduous forest, alder forest, oak forest, and hazel forest (28-32 nymphs/100 m 2), or among dry meadow, meadow, and heath (0 nymphs/100 m(2)). Forestation of open areas is likely to lead to increased I. ricinus abundance and disease risk.
