Rapid Northward Expansion of the Blacklegged Tick, Ixodes scapularis, in Response to Climate Change [PDF]

Global Change Biology, Volume 31, Issue 11, November 2025.
The blacklegged tick, Ixodes scapularis, can transmit human diseases such as Lyme disease and is exposing new human populations to this risk due to its rapid expansion into Canada. We used community science data (eTick and iNaturalist) to understand the environmental factors responsible for the distribution of I.

The Blacklegged Tick, Ixodes scapularis : An Increasing Public Health Concern [PDF]

Trends in Parasitology, 2018
In the United States, the blacklegged tick, Ixodes scapularis, is a vector of seven human pathogens, including those causing Lyme disease, anaplasmosis, babesiosis, Borrelia miyamotoi disease, Powassan virus disease, and ehrlichiosis associated with Ehrlichia muris eauclarensis. In addition to an accelerated rate of discovery of I.

Species distribution models for the eastern blacklegged tick, Ixodes scapularis, and the Lyme disease pathogen, Borrelia burgdorferi, in Ontario, Canada. [PDF]

PLoS ONE, 2020
The blacklegged tick, Ixodes scapularis, is established in several regions of Ontario, Canada, and continues to spread into new geographic areas across the province at a rapid rate. This poses a significant public health risk since I.

Citizen science informs human-tick exposure in the Northeastern United States

International Journal of Health Geographics, 2019
Background Tick-borne disease is the result of spillover of pathogens into the human population. Traditionally, literature has focused on characterization of tick-borne disease pathogens and ticks in their sylvatic cycles.

Estimating Infected Blacklegged Tick Encounters Among Outdoor Workers in Minnesota [PDF]

EcoHealth
Abstract Outdoor workers are at increased risk of tick-borne diseases, yet we poorly understand the interaction between occupational risk factors and worker behavior. This study integrates active tick surveillance with worker-reported survey data to assess how occupational behaviors, demographic characteristics ...

When Clades Collide: Genomic Admixture in Blacklegged Ticks (Ixodes scapularis) From the Great Plains [PDF]

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACTIxodes scapularis ticks transmit a number of pathogens important to human health, including Borrelia burgdorferi sensu stricto, the causative agent of Lyme disease. While I. scapularis is found across the Eastern United States, Lyme disease transmission is largely limited to the Northeast and Upper Midwest and is nearly absent in the South ...

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

Efficacy of a low dose fipronil bait against blacklegged tick (Ixodes scapularis) larvae feeding on white-footed mice (Peromyscus leucopus) under laboratory conditions [PDF]

Parasites & Vectors, 2020
Background Lyme disease is the most prevalent vector-borne disease in the USA with cases continuing to increase. Current control measures have not been shown to be impactful, and therefore alternatives are needed.

Contrasting epigenetics of Ixodes scapularis populations [PDF]

Scientific Reports
Hard ticks are a source of public health concern, in part due to their ability to inhabit different environments. In the United States (US), blacklegged ticks (Ixodes scapularis Say), the primary vector of Lyme disease, exhibit various phenotypes ...
