A study in Tennessee found ticks on about one in six cattle and at livestock monitoring locations in all regions of the state, highlighting a "hidden health threat" to the cattle industry.
Experiments conducted at the U.S. Centers for Disease Control and Prevention showed clothing treated with permethrin had strong toxic effects on three primary germ-carrying tick species, interfering with the ticks' ability to move properly and likely interfering with their ability to bite.
Officials in New Jersey report that the invasive tick Haemaphysalis longicornis has successfully overwintered and was found once again on a rural property in mid-April 2018, after an infestation was reported there in 2017, the first such appearance of the species within North American borders.
A study in Quebec highlights the value of reporting tick bites and submitting tick specimens to public health agencies. Such "passive surveillance" outpaces field collection of ticks in identifying areas of emerging risk for Lyme disease.
A scanning electron micrograph shows an engorged female Ixodes angustus tick with a male I. angustus attached to its underside in typical feeding mode—a case of hyperparasitism presumed uncommon in the species.
In 2017, specimens of an "unusual-looking" tick were discovered in New Jersey and determined to be a species, Haemaphysalis longicornis, native to Asia. No established population of the species has ever been previously documented in the United States.
In her postdoctoral position with the USDA-ARS, entomologist Erika Machtinger directed a field study in which she had to manage "a field staff of six, countless rotating volunteers, laboratory support, and multiple institutions and landowners." All in a day's work for a busy entomologist! Learn more in the first of our new "Standout Early Career Professionals" Q&A series.
A new study in the Journal of Medical Entomology offers the best look yet at the Haller's organ, a small sensory pit on the forelegs of ticks that they use to detect heat and chemical odors emitted by potential hosts.
A new study in Connecticut finds that residential habitats harbor a greater diversity of animal hosts for blacklegged ticks, many of which don't transmit the Lyme disease pathogen Borrelia burgdorferi to ticks as well as white-footed mice do, thereby leading to lower levels of the pathogen's presence in residential areas compared to woodland habitats.
School nurses deal directly with the effects of lice, ticks, and mosquitoes on students and can be an important addition to the IPM team.
If you read the news, it can be easy to wonder why it seems like we’re losing the war against ticks and the diseases they transmit. Why, exactly, are ticks […]
Millions of years of evolution have made ticks highly specialized bloodsuckers. In fact, researchers who have studied tick saliva have found a range of compounds that fight back host defenses […]
Clearing the invasive shrub Japanese barberry from a wooded area once can lead to a significant reduction in abundance of blacklegged ticks for as long as six years
A new species of bacteria that causes Lyme disease needs the same amount of time for transmission after a tick bite compared to previously implicated bacteria, according to new research […]
By Leslie Mertz If you have ever found a deer tick crawling on your shirt or sock, you know how difficult they can be to spot. Adult females are about […]
Ticks have been pathogen-carrying parasites for a very, very long time. A new discovery in a specimen of fossilized amber, roughly 15 million to 20 million years old, reveals a […]
