The seasonal activity pattern of Ixodes dammini was monitored in south-central Wisconsin in 1989 and 1990. Immature tick activity and abundance were assessed by small mammal trapping (732 Peromyscus leucopus examined) and supplemented with flagging. Tick survival and molting times were evaluated by maintaining ticks in environmental chambers at field sites. Results indicate the biology of I. dammini in the upper midwest is similar to that previously reported from the eastern United States. One notable difference was that seasonal larval activity appeared broader (late April through October) and peaked earlier (on 9 July 1989 mean was 7.7 larvae/mouse; on 9 June 1990 mean was 7.3 larvae/mouse). Nymphal activity on P. leucopus peaked in May of both years (mean = 2.5 in 1989; mean = 1.8 in 1990). Bloodfed females placed in the field in early May 1990 oviposited in early June, and larvae emerged by early August. All bloodfed stages successfully overwintered at field sites.
