Genetic and Landscape Connectivity of Blacklegged Ticks During Range Expansion in Select States of the Midwestern USA [PDF]

Ecology and Evolution
Since the 1970s, the Midwestern USA has experienced an expansion of blacklegged ticks (Ixodes scapularis), the primary vector of Lyme disease caused by Borrelia burgdorferi, leading to increased Lyme disease incidence.

Population-Based Passive Tick Surveillance and Detection of Expanding Foci of Blacklegged Ticks Ixodes scapularis and the Lyme Disease Agent Borrelia burgdorferi in Ontario, Canada [PDF]

PLoS ONE, 2014
We identified ticks submitted by the public from 2008 through 2012 in Ontario, Canada, and tested blacklegged ticks Ixodes scapularis for Borrelia burgdorferi and Anaplasma phagocytophilum. Among the 18 species of ticks identified, I.

The Spread of Lone Star Ticks (Amblyomma americanum) and Persistence of Blacklegged Ticks (Ixodes scapularis) on a Coastal Island in Massachusetts, USA [PDF]

Insects
In the northeastern USA, the distribution of lone star ticks (Amblyomma americanum) has expanded northward in recent decades, overlapping with the range of blacklegged ticks (Ixodes scapularis). Blacklegged ticks carry pathogens for diseases such as Lyme,

Accelerated phenology of blacklegged ticks under climate warming. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2015
The phenology of tick emergence has important implications for the transmission of tick-borne pathogens. A long lag between the emergence of tick nymphs in spring and larvae in summer should increase transmission of persistent pathogens by allowing infected nymphs to inoculate the population of naive hosts that can subsequently transmit the pathogen to

Mechanical Acaricides Active against the Blacklegged Tick, Ixodes scapularis

Insects, 2022
Cases of Lyme disease in humans are on the rise in the United States and Canada. The vector of the bacteria that causes this disease is the blacklegged tick, Ixodes scapularis. Current control methods for I. scapularis mainly involve chemical acaricides.

Tritrophic interactions between a fungal pathogen, a spider predator, and the blacklegged tick [PDF]

Ecology and Evolution, 2018
The blacklegged tick Ixodes scapularis is the primary vector for the bacterium causing Lyme disease in eastern North America and for other medically important pathogens.

Circadian regulation of locomotion, respiration, and arousability in adult blacklegged ticks (Ixodes scapularis) [PDF]

Scientific Reports
The blacklegged tick, Ixodes scapularis, is an ectoparasitic arachnid and vector for infectious diseases, including Lyme borreliosis. Here, we investigate the diurnal activity and respiration of wild-caught and lab-reared adult ticks with long-term video

Blacklegged ticks, Ixodes scapularis, reduce predation risk by eavesdropping on communication signals of Formica oreas thatching ants [PDF]

Royal Society Open Science
Ticks spend most of their life inhabiting leaf litter and detritus where they are protected from sun but preyed upon by ants. Ants secrete chemical communication signals to coordinate group tasks such as nest defence.

Seasonality in Diurnal Locomotory Patterns of Adult Blacklegged Ticks (Acari: Ixodidae) [PDF]

Journal of Medical Entomology, 2005
We continuously recorded the activity of adult and nymphal blacklegged ticks, Ixodes scapularis Say, exposed to diurnal light and temperature cycles in a laboratory test chamber by using a digital camera controlled by an intervalometer. Adult ticks collected and tested in the fall exhibited a bimodal pattern of activity, with peaks shortly after lights

In vitro and in vivo acaricidal properties of orally delivered ivermectin against the blacklegged tick, Ixodes scapularis [PDF]

Parasites & Vectors
Background The lack of effective and affordable new environmental tick control products is one of the major challenges to the existing control strategies against the blacklegged tick (Ixodes scapularis), the vector of Lyme disease affecting public health
