Recent reports of winter tick, Dermacentor albipictus, from dogs and cats in North America
Veterinary Parasitology: Regional Studies and Reports, 2020Dermacentor albipictus, a common one-host tick of large animals in North America, is most often reported from moose (Alces alces) and is rarely implicated as a parasite of cats and dogs. From 2018 to 2020, 4 dogs and 4 cats from United States and 3 dogs from Canada were infested with D. albipictus.

The larval stage of the one-host tick, Dermacentor albipictus Packard (Acari: Ixodidae), the winter tick, is spent aggregated on the ground in summer until they quest for hosts in the autumn. Metarhizium brunneum (Petch) and Beauveria bassiana (Balsamo-Crivelli) Vuillemin are promising fungal biocontrol agents of ticks.

The chemical 2,6-dichlorophenol, previously identified as a sex pheromone in several species of hard ticks, was found in both sexes of 2 additional species, Dermacentor albipictus and Haemaphysalis leporispalustris .

Abstract: Larvae of winter ticks, Dermacentor albipictus (Packard), ascend vegetation in autumn and form clumps that attach to passing ungulate hosts. We tested the hypothesis that vegetation height determines the height of clumps. During the vegetation-to-ungulate transmission period (early September to mid-November), larvae were released. at the base

TICK (DERMACENTOR ALBIPICTUS)-INDUCED WINTER HAIR-LOSS IN CAPTIVE MOOSE (ALCES ALCES)
Journal of Wildlife Diseases, 1986Five captive moose calves each infested with 42,000 larval Dermacentor albipictus, six calves each infested with 19,000-21,000, and five control moose were observed for changes in hair-loss, body condition and number, stages, and distribution of the tick. Winter hair-loss was observed only in moose infested with ticks and was correlated positively with

Karyotype, sex determination, and meiosis were studied in the one-host tick, Dermacentor albipictus. Males possess 20 autosomes plus 1 sex chromosome. Ten autosomal bivalents and 1 sex univalent are present at diplonemma, diakinesis, and metaphase I; reduction division, at least for the sex chromosome, occurs at anaphase I.

Reproduction of the winter tick, Dermacentor albipictus, under laboratory conditions
Canadian Journal of Zoology, 1987Reproductive performance and development of the winter tick, Dermacentor albipictus, were studied under controlled conditions using multiple replicates along a time series. Engorged female ticks cold stressed at various temperatures before incubation at 25 °C laid more eggs, and the number of eggs laid per gram of engorged female was higher, than ...

Molecular detection of Rickettsia felis in Dermacentor albipictus from Mississippi
Journal of Medical EntomologyAbstract Dermacentor albipictus (Packard), the winter tick, is a one-host tick often found in high numbers on horses, moose, elk, and deer in the northern United States and parts of Canada. In Mississippi, there have been very few collections of D. albipictus. Herein we report the collection and molecular screening of 5 male specimens

Densities of winter ticks (Dermacentor albipictus) were determined on each of 20 moose (Alces alces) half-hides by dissolving 100 cm2 quadrats in potassium hydroxide solution. Data were then used to determine the optimum sampling fraction for estimating tick densities.
