TLDR
A total of 3,235 Dermacentor variabilis specimens were collected from birds, mammals, and by dragging vegetation, and 2,683 D. albipictus (Packard) ticks were collection from deer from 1993 to 1996, with peak seasonal occurrence of adult and nymphal D. Variabilis populations peaked in June.Abstract:
A total of 3,235 Dermacentor variabilis (Say) specimens were collected from birds, mammals, and by dragging vegetation, and 2,683 D. albipictus (Packard) ticks were collected from deer from 1993 to 1996. Peak seasonal occurrence of adult D. variabilis was from May through July with a precipitous decrease in August. Nymphal D. variabilis populations peaked in June. Peak activity of larvae was bimodal, with one activity peak during late summer (September) and a second peak in winter or early spring. The raccoon, Procyon lotor (L.), was the principal host of adults followed by the Virginia opossum, Didelphis virginiana Kerr. Rodents and the eastern cottontail rabbit, Sylvilagus floridanus (J. A. Allen), were the primary hosts of nymphs. The marsh rice rat, Oryzomys palustris (Harlan), was the principal host of larvae followed by the pine vole, Microtus pinetorum (Le Conte), and white-footed mouse, Peromyscus leucopus (Rafinesque). All stages of D. albipictus were found only on white-tailed deer, Odocoileus virginianus (Zimmermann). Numbers of adult and nymphal D. albipictus peaked in November, whereas larvae peaked in September.read more

First Detection of Heartland Virus (Bunyaviridae: Phlebovirus) from Field Collected Arthropods
Harry M. Savage,Marvin S. Godsey,Amy J. Lambert,Nicholas A. Panella,Kristen L. Burkhalter,Jessica R. Harmon,R. Ryan Lash,David C. Ashley,William L. Nicholson +8 more
TL;DR: This is the first study to isolate HRTV from field-collected arthropods and to implicate ticks as potential vectors and Sequence data from the nonstructural protein of the Small segment indicates that tick strains and human strains are very similar.

Transovarial Transmission of Francisella-Like Endosymbionts and Anaplasma phagocytophilum Variants in Dermacentor albipictus (Acari: Ixodidae)

TL;DR: The transovarial transmission of A. phagocytophilum variant-1 associated with Ixodes scapularis ticks and white-tailed deer as well as that of the human-pathogenic A. albipictus may not be solely dependent on horizontal transmission.
Journal ArticleDOI
Host surveys, ixodid tick biology and transmission scenarios as related to the tick-borne pathogen, Ehrlichia canis.
TL;DR: Natural exposure studies and experimental investigations of E. canis are summarized in the context of what is understood about biological vectors of tick-borne Anaplasmataceae to elucidate similar interactions for other Ehrlichia species.

Range Expansion of Dermacentor variabilis and Dermacentor andersoni (Acari: Ixodidae) Near their Northern Distributional Limits
TL;DR: Twenty-nine species of mammals and three species of birds were identified as hosts for different life stages of these ticks and range expansion of D. variabilis has resulted in a zone of sympatry at least 200 km wide.
Journal ArticleDOI
Differentiation of three species of ixodid tick, Dermacentor andersoni, D. variabilis and D. albipictus, by PCR-based approaches using markers in ribosomal DNA.
TL;DR: A practical polymerase chain reaction (PCR) assay, based on the amplification of part of the second internal transcribed spacer ribosomal DNA (pITS-2 rDNA), was developed to distinguish D. andersoni from D. variabilis and single-strand conformation polymorphism (SSCP) analysis of the pITS-1 rDNA provided a reliable method of distinguishing specimens of the three species of ixodid tick.
