Experimental Parasitology, 2022
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 Journal of Parasitology, 1972
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.

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

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 ...

Experimental and Applied Acarology, 2012
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.
