Bacterial Communities of Ixodes scapularis from Central Pennsylvania, USA [PDF]

Insects, 2020
Native microbiota represent a potential resource for biocontrol of arthropod vectors. Ixodes scapularis is mostly inhabited by the endosymbiotic Rickettsia buchneri, but the composition of bacterial communities varies with life stage, fed status, and/or geographic location. We compared bacterial community diversity among I.

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

Pest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

A preliminary linkage map of the tick, Ixodes scapularis

Experimental & Applied Acarology, 2002
A linkage map of the Ixodes scapularis genome was constructed based upon segregation amongst 127 loci. These included 84 random amplified polymorphic DNA (RAPD) markers, 32 Sequence-Tagged RAPD (STAR) markers, 5 cDNAs, and 5 microsatellites in 232 F1 intercross progeny from a single, field-collected P1 female.

A comparative evaluation of northern and southern Ixodes scapularis questing height and hiding behaviour in the USA

Parasitology, 2020
Ticks display a distinct type of host-seeking behaviour called questing. It has been proposed that the questing behaviour of Ixodes scapularis explains the geographic variation in Lyme disease (LD) risk in the eastern USA because the northern population ...

Our Changing Climate Is Presenting Major Challenges to the Great Lakes Region

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT The Earth's climate, including that of North America, is changing rapidly and the corresponding changes in temperature, precipitation, extreme weather, and other effects are accelerating. This changing climate is affecting the region around the Great Lakes and the physical behavior of the Great Lakes themselves, presenting new challenges to ...

Anomalous morphologies in Ixodes scapularis feeding on human hosts

Ticks and Tick-borne Diseases, 2022
Cases of anomalous morphologies in the blacklegged tick, Ixodes scapularis, have been reported in both field-collected and human-biting specimen in the Northeastern and Midwestern United States, complicating the identification of this medically important tick species. We herein describe four cases of morphological anomalies in I.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, Volume 13, Issue 1, 5 January 2026.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Borrelia burgdorferiinIxodes scapularisTicks, Chicago Area

Emerging Infectious Diseases, 2006
To the Editor: Lyme disease is a multisystem disorder associated with skin, myocardial, musculoskeletal, and central and peripheral nervous system manifestations caused by infection with Borrelia burgdorferi sensu lato spirochetes (1). In the United States, the illness is caused by transmission of B.

Identification and characterization of Ixodes scapularis antigens that elicit tick immunity using yeast surface display. [PDF]

PLoS ONE, 2011
Repeated exposure of rabbits and other animals to ticks results in acquired resistance or immunity to subsequent tick bites and is partially elicited by antibodies directed against tick antigens.

RNAi‐mediated gene silencing of a 26S proteasome subunit increases mortality of the Japanese beetle Popillia japonica

Pest Management Science, Volume 82, Issue 1, Page 1066-1078, January 2026.
We propose the regulatory particle non‐ATPase subunit 6 of the 26S proteasome as a first good promising RNA interference target candidate to control the Japanese beetle Popillia japonica. This will help to optimize a double‐stranded RNA insecticide against this priority pest with low off‐target effects on pollinators on a gene sequence‐based prediction.
