Factors Influencing the Potential Establishment of the Winter Tick (Dermacentor albipictus) in Alaska

Journal of Wildlife Diseases, 1990
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, 1988
Moose, 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.

Some Factors Affecting Infestation of White-Tailed Deer by Blacklegged Ticks and Winter Ticks (Acari: Ixodidae) in Southeastern Missouri

Journal of Medical Entomology, 1997
A total of 5,669 ticks of 4 species was collected from 515 hunter killed, white-tailed deer. Odocoileus virginianus (Zimmerman), in southeastern Missouri from 1993 through 1995. The American dog tick, Dermacentor variabilis (Say) (4 adults), the lone star tick, Amblyomma americanum (L.) (57 adults, 2 nymphs), the blacklegged tick, Ixodes scapularis ...

Trends of Winter Nutritional Restriction, Ticks, and Numbers of Moose on Isle Royale

The Journal of Wildlife Management, 1997
During a 7-year study, we monitored winter nutritional restriction of moose (Alces alces) and moose numbers on Isle Royale (winters 1987-88 to 1993-94). Over the 7 winters, the estimated moose population decreased 26% from an historic high of 1,653 (winter 1987-88) to 1,216 (1989-90), then increased to a new high (1,880 and 1,770) by winters 1992-93 ...

Effect of Solvents on Engorged Female Winter Ticks 1966-79

Insecticide and Acaricide Tests, 1980
Abstract Procedures used to evaluate candidate insecticides for arthropod control usually require that the insecticide be dissolved in a solvent. At Kerrville, we have investigated the effect of AR grade solvents, at various times since 1966, by dipping ticks into neat solvent.

Reproduction and transmission of the winter tick, Dermacentor albipictus (Packard) in central Alberta

1984
Masters thesis. A two part study, involving a field and laboratory component, was developed to provide information on the reproductive performance and transmission of D. albipictus under field conditions and relate this information to the die-off of moose in Alberta.
