‘Vector Biology Boot Camp’ empowers disease professionals

Penn State Extension, in partnership with the Northeast Regional Center for Excellence in Vector-Borne Diseases, recently hosted the three-day “Vector Biology Boot Camp” to provide hands-on experience for vector-borne disease professionals in field collection and identification of medically important ticks and mosquitoes in the Northeast.

The bite stops here: Fighting Lyme disease with prevention

As spring temperatures rise, many people will spend more time on outdoor activities, increasing their risk of encountering pathogen-carrying ticks.

'Prescribed' Fires' Hidden Bonus: Fewer Ticks

A tool used to restore forest ecosystems could also be key to the battle against tick-borne disease, researchers say.

Prescribed fire could reduce tick populations and pathogen transmission

Prescribed fire — a tool increasingly used by forest managers and landowners to combat invasive species, improve wildlife habitat and restore ecosystem health — also could play a role in reducing the abundance of ticks and the transmission of disease pathogens they carry, according to a team of scientists.

8 best insect repellents: DEET and DEET-free bug sprays

One preventative and protective measure you can take to avoid bug bites is applying insect repellent. Figuring out which ones are actually effective can be confusing, though, seeing as the labels are often covered with complicated ingredients and jargon like “DEET” and “all-natural.”

To educate the public about tick risk and tick bite prevention in these companion animals, Penn State Extension will offer the spring 2022 “Tick Webinar Series.” The vector-borne disease extension team will hold three webinars in May — Lyme Disease Awareness Month — at no cost to participants.

Ticks and mosquitoes may await the pandemic-weary seeking outdoor exercise

Pandemic-weary Americans have begun walking and hiking in recent months to get out of the house while avoiding infection with the novel coronavirus. At the same time, resource-strapped local health departments have been forced to divert money and people to covid-related activities, unwillingly creating openings for outside exercisers to get sick in other ways.

Ticks - biology, threats, protections - are focus of 10-week Penn State webinar series

Ticks, Lyme disease, other tick-borne diseases and Pennsylvania’s No. 1 position in all of that will be explained in detail in a free, 10-part webinar series from Penn State Extension that begins Thursday, July 9, with weekly installments scheduled through September 17.
