Tick threat not necessarily linked to longer grass in urban backyards

In a recent publication, USDA Forest Service researchers Susannah Lerman and Vince D’Amico report on their quest to get to the bottom of a common assumption that ticks like long grass. They tested the hypothesis that lawn mowing frequency influences tick occurrence in 16 suburban yards in Springfield, MA. by conducted tick drags in lawns of various lawn mowing frequencies . They  did not collect any ticks of any species. Promoting frequent mowing (i.e., shorter lawns) and the removal of grass clippings could have minimal impacts on tick microhabitats, but is consequential for beneficial wildlife and other ecosystem services associated with urban biodiversity.”

Ted Talk about the threat Ticks pose to Human Health

In this talk, we learn about the dangerous threats that the expansion of ticks in the world means to human health. Mary Beth Pfeiffer is the nation’s leading investigative reporter on Lyme disease, winning seven awards since 2012 for her reporting on the tick-borne scourge. She recently authored the book Lyme: The First Epidemic of Climate Change, which has been endorsed by Jane Goodall and Bill McKibbon and praised as “superbly written” and a “powerful wakeup call.”

Distribution, Host-Seeking Phenology, and Host and Habitat Associations of Haemaphysalis longicornis Ticks, Staten Island, New York, USA

 Haemaphysalis longicornis, an invasive Ixodid tick, was recently reported in the eastern United States. The emergence of these ticks represents a potential threat for livestock, wildlife, and human health. We describe the distribution, host-seeking phenology, and host and habitat associations of these ticks on Staten Island, New York, a borough of New York City.

Tick-borne disease is multiple microbial in nature

A study recently published in Scientific Reports discovered that 65% of Lyme disease patients irrespective of their disease stage respond to several microbes. As a consequence, the authors have demonstrated that microbial infections in individuals suffering from Lyme disease do not follow the “one microbe, one disease” status-quo. Moreover, the probability that Lyme disease patients would respond to multiple microbes associated with the tick-borne disease is an astounding 85 %.

Tick Study – Blacklegged Ticks Larvae and Nymphs’ Habitat is a Mystery in the Southern U.S.

In the southern U.S., blacklegged tick larvae and nymphs can be found on hosts, but they don’t otherwise show up in vegetation or—as a new study finds—in leaf litter or soil either. Learn more about how researchers at Texas A&M University dug up leaf litter and soil samples hoping to uncover the life history of larval and nymphal blacklegged ticks:

TickEncounter Uses Crowd Sourced Information to Learn About Asian Longhorned Ticks

Tom Mather’s blog provides evidence for using the “Power of the Crowd” and ground proofing certain findings. Tom’s most recent write up about a trip to Staten Island in search of the Asian longhorned tick is a must read: https://tickencounter.org/tick_notes/three_surprising_things

The articles three surprising findings are:

  1. Longicornus larvae hang out together on the tips of grasses, but like a bomb, they explode when something brushes by.
  2. Without magnification, nymphal Asian longhorned ticks look very similar to nymphal Lone Star ticks.
  3. Asian longhorned ticks are way more established than Tom expected to find.
