Eight Hereford heifer calves were infested 28 times over a 64-d period with approximately 49,560 Dermacentor albipictus (Packard) larvae per calf. The fecundity of partially engorged and small, fully engorged female ticks, prematurely removed by grooming behavior of the calves, were compared.

Experimental and Applied Acarology, 2021
In total, 57 ticks were collected from six white-tailed deer (Odocoileus virginianus) and three mule deer (O. hemionus) in northern Mexico during the 2017, 2018 and 2019 hunting seasons. Morphological features of adult male and female ticks were observed and photographed using a stereo-microscope and scanning electron micrography.

Competition among ticks, and among ectoparasites generally, has rarely been demonstrated. Ixodes scapularis and Dermacentor albipictus are both hard ticks commonly found feeding on deer harvested at Letterkenny Army Depot, in south central Pennsylvania, USA. The two species have contrasting life histories resulting in D.

Gaps and opportunities in on‐host winter tick (Dermacentor albipictus) surveillance in North America
Journal of Wildlife ManagementThe investigation and management of the impacts of winter tick infestations on moose in North America necessitates coordinated surveillance and intervention efforts. The current absence of searching for winter ticks on other potential ungulate hosts, largely based on historical beliefs of predilection from limited captive studies, has created a ...

Dermacentor albipictus ON MOOSE (Alces alces) IN ONTARIO
Journal of Wildlife Diseases, 1979Fifty-five moose (Alces alces) collected from 1963 to 1965 in the Chapleau Crown Game Preserve of northern Ontario were examined for ectoparasites. Dermacentor albipictus was the only parasite recovered. D. albipictus was absent from 15 moose examined during June, July and August; first observed on 1 or 2 moose examined in September; and present on all

ORIGIN OFDERMACENTOR ALBIPICTUS(ACARI: IXODIDAE) ON ELK IN THE YUKON, CANADA
Journal of Wildlife Diseases, 2014Winter ticks (Dermacentor albipictus) on elk (Cervus elaphus canadensis) have recently increased in numbers in the Yukon, Canada, potentially posing risks to other indigenous host species in the region. To evaluate the regional source of winter ticks in the Yukon, we sequenced one nuclear (ITS-2) and two mitochondrial (16SrRNA and COI) genes, and ...

The winter tick (Dermacentor albipictus) is not known to occur in Alaska. Survival and development of free-living (i.e., non-host-associated) stages of the tick were studied at three sites in central and southern Alaska. Female ticks survived, oviposited, and eggs hatched at all sites.

Growth and Development of Winter Tick, Dermacentor albipictus, on Moose, Alces alces
The Journal of Parasitology, 1988Moose, Alces alces, were infested with 21,000 or 42,000 larval Dermacentor albipictus at the end of September. Larvae grew rapidly and molted to the nymphal stage 10-22 days after infestation. The nymphal stage lasted approximately 3 mo until mid-January and was characterized by a diapause.

Hormonal Termination of Larval Diapause in Dermacentor albipictus
Science, 1969The molting hormone, α-ecdysone, and an analog Δ 7 -5β-cholestene-2β,3β,14α-triol-6-one when applied externally, terminates diapause in larvae of the winter tick, Dermacentor albpictus . This is the first reported hormonal termination of diapause in an arthropod other than an insect.
