Identification of a novel ß-adrenergic octopamine receptor-like gene (ßAOR-like) and increased ATP-binding cassette B10 (ABCB10) expression in a Rhipicephalus microplus cell line derived from acaricide-resistant ticks [PDF]

open access: yes, 2016
Background: The cattle tick Rhipicephalus (Boophilus) microplus is an economically important parasite of livestock. Effective control of ticks using acaricides is threatened by the emergence of resistance to many existing compounds. Several continuous R.

Improving distribution models of sparsely documented disease vectors by incorporating information on related species via joint modeling

open access: yesEcography, Volume 2025, Issue 3, March 2025.
A necessary component of understanding vector‐borne disease risk is accurate characterization of the distributions of their vectors. Species distribution models have been successfully applied to data‐rich species but may produce inaccurate results for sparsely documented vectors. In light of global change, vectors that are currently not well‐documented

The Distinct Transcriptional Response of the Midgut of Amblyomma sculptum and Amblyomma aureolatum Ticks to Rickettsia rickettsii Correlates to Their Differences in Susceptibility to Infection

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Rickettsia rickettsii is a tick-borne obligate intracellular bacterium that causes Rocky Mountain Spotted Fever (RMSF). In Brazil, two species of ticks in the genus Amblyomma, A. sculptum and A.

New tick records in Rondônia, Western Brazilian Amazon Novos relatos de carrapatos em Rondônia, Amazônia ocidental brasileira

open access: yesRevista Brasileira de Parasitologia Veterinária, 2010
In the present study, we provide new tick records from Vilhena Municipality, in the Southeast of the State of Rondônia, Northern Brazil. Ticks collected from a capybara, Hydrochoerus hydrochaeris (Linnaeus), were identified as Amblyomma romitii Tonelli ...

Bayesian prediction of Amblyomma variegatum dynamics using hidden process models [PDF]

open access: yes, 2014
In silico evaluation of tick and TBD control practices requires a predictive dynamic framework that (1) approximates key density dependant / independent processes affecting tick numbers (2) captures the effects of external stochasticity (3) integrates ...

Metagenomic-based Surveillance of Pacific Coast tick Dermacentor occidentalis Identifies Two Novel Bunyaviruses and an Emerging Human Ricksettsial Pathogen. [PDF]

open access: yes, 2017
An increasing number of emerging tick-borne diseases has been reported in the United States since the 1970s. Using metagenomic next generation sequencing, we detected nucleic acid sequences from 2 novel viruses in the family Bunyaviridae and an emerging ...

Novel use of a servosphere to study apodous insects: Investigation of blow fly post‐feeding larval dispersal

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 1, Page 14-21, March 2025.
A servosphere was used to record the speed, directionality and phototaxis of individual post‐feeding larvae of two species of blow fly (Diptera: Calliphoridae) on a smooth plastic surface over time. The servosphere rotates to compensate for the movement of an insect placed at its apex, thereby facilitating its unimpeded locomotion in any direction and ...
