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.
One key factor plays a role in how well any particular tick-management method might work: Which tick species is it best suited for? A new guide in the Journal of Integrated Pest Management reviews research on tick management tools and their effectiveness on three tick species: the blacklegged tick, the lone star tick, and the American dog tick.
A study of lone star ticks in the forested Missouri Ozarks found that nymphs and adults were more abundant in valleys and on north-facing hills than in other areas. Meanwhile, nymphs appeared less often in the areas of greater temperature variability, while adults were less prevalent with increased elevation.
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 new review of 30 years' worth of research concludes that, while lone star ticks are guilty of transmitting bacteria that cause several human illnesses, Lyme disease is not one of them.
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.
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 […]
Reduction in deer populations won't prevent Lyme Disease, but can reduce the risk
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 […]
The winter of 2011-2012 was a mild one in the New York City area, and the following summer saw the lowest population density of nymphal blacklegged ticks (Ixodes scapularis) in […]
An emerging tool in the fight against tick-borne disease, host-targeted bait boxes employ a sneaky trick: turning some of ticks’ favorite carriers —small mammals like mice and chipmunks —against them. […]
An international team of scientists led by Purdue University has sequenced the genome of the tick that transmits Lyme disease, the most common vector-borne illness in North America. Ixodes scapularis, […]
By Hannah Foster Lyme disease is a potentially debilitating disease caused by the bacterium Borrelia burgdorferi. The disease is spread to humans by two tick varieties: the blacklegged tick (Ixodes […]
By Hannah Foster Oh no! You’ve found a tick! Who ya gonna call? TICKSPOTTERS! Maybe ticks haven’t started popping up in your neighborhood yet, but they probably will soon. That’s […]
