Density-Dependent Seasonal Dynamics of Blacklegged Tick (Acari: Ixodidae) Nymphs
Journal of Medical Entomology, 1997The midsummer seasonal decline in abundance of unfed Ixodes scapularis Say nymphs on experimental plots in New Jersey was density-dependent. Nymph density was manipulated on 9 plots (10 by 10 m each) in Morristown. National Historical Park, NJ, in early June 1994.

Nocturnal Questing by Adult Blacklegged Ticks, Ixodes scapularis (Acari: Ixodidae)
The Journal of Parasitology, 1996Quantitative tick drag samples were taken at various times during the day and night from February through April 1994 on St. Catherines Island or on Sapelo Island, Georgia. For each month, there was no statistical difference between the numbers of adult blacklegged ticks, Ixodes scapularis, collected during any hour of daylight or darkness on St ...

FACTORS INFLUENCING THE DISTRIBUTION OF LARVAL BLACKLEGGED TICKS ON RODENT HOSTS
The American Journal of Tropical Medicine and Hygiene, 2003Because of differences among hosts in reservoir competence for tick-borne diseases, the distribution of larval blacklegged ticks on hosts might determine tick infection prevalence and disease risk to humans. We conducted a three-part study to determine the factors responsible for greater burdens of larval blacklegged ticks on white-footed mice than on ...

Transient influence of blood meal and natural environment on blacklegged tick bacterial communities.
Ticks and Tick-borne Diseases, 2018 Blacklegged ticks (Ixodes scapularis) spend the majority of their life cycle off host, typically in woodland habitat, but require a blood meal at each of three life stages (larva, nymph, adult) to reach maturity and reproduce. Blood feeding usually lasts for several days each time and as blood is imbibed, a range of known pathogens from the host may ...

Spring Migratory Birds (Aves) Extend the Northern Occurrence of Blacklegged Tick (Acari: Ixodidae)
Journal of Medical Entomology, 1996Birds that had migrated northward across Lake Superior were captured upon reaching landfall at Thunder Cape (48 degrees 18' N, 88 degrees 56' W) at the southwestern tip of the Sibley Peninsula, northwestern Ontario, from 9 May to 9 June 1995. Twenty-one of 530 birds examined (6 of 55 species) had a total of 34 ticks; 1 blue jay, Cyanocitta cristata ...

Journal of Medical Entomology, 1997
A model (LYMESIM) was developed for computer simulation of blacklegged tick, Ixodes scapularis Say, population dynamics and transmission of the Lyme disease agent. Borrelia burgdorferi Johnson. Schmid, Hyde, Steigerwalt & Brenner, LYMESIM simulates the effects of ambient temperature, saturation deficit, precipitation, habitat type, and host type and ...

Notes on Responses of Blacklegged Ticks (Acari: Ixodidae) to Host Urine
Journal of Medical Entomology, 1999In laboratory bioassays under conditions of high humidity, host-seeking female black-legged ticks, Ixodes scapularis Say, avoided urine of reproductively active male and nonestrous female white-tailed deer, Odocoileus virginianus (Zimmermann), the principal host species of the adult stage. At 50% RH, female I.

Northeastern Naturalist, 2019
— Ixodes scapularis (Blacklegged Tick), vector of Lyme disease, has a broad distribution in eastern North America, but is relatively rare in Missouri. In this study, we report the change in abundance of this species in Adair County, MO, from 2006 to 2015.

Estimating Population Size and Drag Sampling Efficiency for the Blacklegged Tick (Acari: Ixodidae)
Journal of Medical Entomology, 2000Estimates of absolute density were determined over a 5-yr period (1990-1994) for a population of Ixodes scapularis Say located in Westchester County, NY, by mark-release-recapture (nymphs and adults) and removal (larvae) methods. Density estimates for larvae ranged from 5.2 to 16.5/m2 and averaged 11.5/m2.
