Abstract. The seasonal temporal and spatial distribution and emergence of overwintering and summer cohorts of host‐seeking American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae), adults were examined for 5 years in the Bluegrass region of Kentucky. Weekly drag cloth sampling was conducted from early March until late September 1992–1995 and early March until the end of May 1996. Overwintering adult cohorts became active in early to mid‐April followed by bimodal host‐seeking activity… 

Abundance and seasonal activity of adult Dermacentor reticulatus (Acari: Amblyommidae) in eastern Poland in relation to meteorological conditions and the photoperiod.

The investigations demonstrated that the activity dynamics in D. reticulatus from eastern Poland is similar to that in the southern European population, but different from that inThe north-eastern Polish, Russian and West European populations, which indicates a need to monitor the threats of diseases transmitted by D.reticulanus within different regions of its range of geographic distribution.

Study of the life cycle of Amblyommadubitatum (Acari: Ixodidae) based on field and laboratory data

Though A. dubitatum has a one year life cycle, more than one cohort can co-exist within the same population in a certain interval of time, and the potential role of small rodents as hosts for larvae and nymphs of A.dubitatum is confirmed.

Short day-triggered quiescence promotes water conservation in the American dog tick, Dermacentorvariabilis

It is concluded that a short day-triggered quiescence reduces desiccation stress associated with overwintering in nonfed ticks, which is critical to prevent dehydration during the dry winter periods.

Updated ecology and distribution of tick species in Oklahoma

It is anticipated that these results will assist efforts to better understand the epidemiology of the different disease caused by pathogens transmitted by these tick species within the Great Plains region.

Heterogeneous Associations of Ecological Attributes with Tick-Borne Rickettsial Pathogens in a Periurban Landscape.

This study elucidates the complexity of tick-borne pathogen ecology and points to the need for further studies on the role of reservoir hosts, particularly that played by small vertebrates, which is not fully understood in the region.

Host Associations of Dermacentor, Amblyomma, and Ixodes (Acari: Ixodidae) Ticks in Tennessee

Despite unequal sampling among ecoregions, the large numbers of D. variabilis and A. americanum from multiple host species suggest their widespread distribution throughout the state.

American dog ticks along their expanding range edge in Ontario, Canada

The American dog tick, Dermacentor variabilis, is a tick of public and veterinary health importance in North America. Using passive tick surveillance data, we document distribution changes for the



Seasonal dynamics of American dog tick, Dermacentor variabilis (Say), populations in southwestern Nova Scotia.

Seasonal activity and host relationships of the American dog tick in three areas of southwestern Nova Scotia are described from 1973 to 1975. The majority of Dermacentor variabilis individuals

Variations in Population Density, Movement, and Rickettsial Infection Rates in a Local Population of Dermacentor variabilis (Acarina: Ixodidae) Ticks in the Piedmont of Georgia

Adult Dermacentor variabilis ticks studied from 1978 through 1981 in an area with a high incidence of Rocky Mountain spotted fever in Georgia were found to begin questing in late March to mid-April, indicating that a 1-year life cycle occurs in the area.

Ecological investigations of the american dog tick, Dermacentor variabilis (say), in northwest Ohio (Acari: Ixodidae)

Ecological investigations on Dermacentor variabilis were conducted in both the laboratory and a metropark area in Lucas County, Ohio and white-footed mice served as the primary host species.

Ecology of the American Dog Tick, Dermacentor variabilis, in a Study Area in Virginia. 2. Distribution in Relation to Vegetative Types.

The relationship between distribution of Dermacentor variabilis (Say) and vegetation was studied and radioisotope-tagged ticks to study the relationship between tick distribution and vegetation appears to have been useful and is of interest because the results can be related to the number of individuals released.

Population dynamics of the American dog tick (Acari: Ixodidae) in relation to small mammal hosts.

A strong positive relationship between size of adult tick populations and size of small mammal populations, especially of meadow voles, indicated that feeding success of immature ticks is the most important factor regulating adulttick populations.

Population Dynamics of American Dog Ticks (Acari: Ixodidae) Along Park Trails

Insight is provided into turnover rates of the adult Dermacentor variabilis population and effectiveness of the drag as a sampling device and no evidence of reduced tick numbers on removal trails is found.

Distribution of the American dog tick, Dermacentor variabilis (Say), and its small-mammal hosts in relation to vegetation types in a study area in Nova Scotia.

The distribution of Dermacentor variabilis and its mammal hosts was related to vegetation types found in a 12-ha area of southwestern Nova Scotia during summers of 1974 to 1977. Cluster and principal

The abundance and distribution of Amblyomma americanum (L.) and Dermacentor variabilis (Say) among nine species of medium-sized mammals were examined at an integrated tick management site at Land

Ticks infesting medium-sized wild mammals in two forest localities in Virginia (Acarina: Ixodidae).

Studies done in Piedmont habitat consisting of isolated, mixed deciduous forest tracts in various stages of succession adjacent to abandoned pasture, cropland, and cultivated fields revealed the presence of 4 species of ticks parasitizing 7 species of medium-sized mammals.

Seasonal dynamics and distribution of American dog tick, Dermacentor variabilis (Say), larvae and nymphs at Birds Hill Park, Manitoba

During a 2-year study on the relationships between immature Dermacentor variabilis and their small-mammal hosts near Birds Hill, Manitoba, 739 captures of 427 mammals were examined for ticks.
