Savage Tick-Clone Armies are Sucking Cows to Death; Experts Fear for Humans, ArsTechnica, July 11, 2019.


Deadly Tick Attacks
"Ravenous swarms of cloned ticks have killed a fifth cow in North Carolina by exsanguination—that is, by draining it of blood—the state’s Department of Agriculture and Consumer Services warned this week."

Clone Armies of Death
"...a single well-fed female can spawn up to 2,000 tick clones parthenogenetically—that is, without mating—in a matter of weeks."

Unique Persistence
"...unlike other ticks that tend to feast on a victim for no more than seven days, mobs of H. longicorni can latch on for up to 19 days."

"...the National Veterinary Services Laboratories looked back through their tick samples and discovered a larval H. longicornis was isolated from a white-tailed deer in Tyler County, West Virginia, in 2010, backdating the first case known in the US. Still, researchers don’t know when the tick first arrived and were it came from."

"...the tick is known to spread SFTSV, short for the Severe fever with thrombocytopenia syndrome virus. SFTSV is related to Heartland virus found in the US and has had reported mortality rates up to 30%."

"H. longicorni is also known to transmit Rickettsia japonica, the cause of Japanese spotted fever, and Theileria orientalis, which is behind cattle theileriosis. It has also been found harboring relatives of US pathogens, including those that cause anaplasmosis, ehrlichiosis, babesiosis, and the Powassan virus."

Current Known Range
"H. longicorni populations are known to exist in Arkansas, Connecticut, Kentucky, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Virginia, and West Virginia."

Nasty Tick Rapidly Filling up Staten Island, East Coast

New Yorkers brace for self-cloning Asian longhorned tick,
Columbia University, March 28, 2019.


Staten Island
“...the population of a new, potentially dangerous invasive pest known as the Asian longhorned tick has grown dramatically across the borough...”

Self Cloning and Growing…
“...the tick--which unlike other local species can clone itself in large numbers--is likely to continue its conquest in the months ahead.”

Nasty NY
“...the Staten Island infestation is far more advanced than previously known.”

“ 7 of 13 parks surveyed in 2017 and in 16 of 32 in 2018.”

“In one park, the density of the ticks per 1000 square meters rose almost 1,698 percent between 2017 and 2018, with the number of ticks picked up in the sample area rising from 85 to 1,529. They also found the ticks on anesthetized deer from the area.”

Very Rapid Growth & Spread
“The news comes less than a year after the New York City Department of Health announced the discovery of the first member of the species in the city--a single tick--found on southern Staten Island last August.”

Too Late
“Public health officials are particularly concerned because the longhorned tick is notorious for its ability to quickly replicate itself. Unlike deer ticks, the common local variety known for carrying Lyme disease, the female Asian longhorned can copy itself through asexual reproduction in certain environmental conditions, or reproduce sexually, laying 1,000-2,000 eggs at a time. They are typically found in grass in addition to the forested habitats that deer ticks prefer, adding a new complication to public health messaging. The Columbia analysis suggests that the public warnings may have come too late.”

"The fact that longhorned tick populations are so high in southern Staten Island will make control of this species extremely difficult…"

“The tick, native to Asia and Australia, had been identified in the months prior to the Staten Island sighting in New Jersey, West Virginia, North Carolina and Arkansas and just a few weeks earlier in Westchester County.”

“The first Asian long-horned tick in the U.S. was identified in New Jersey in 2013. A large population was later found on sheep in Mercer County, New Jersey.”

Huge Numbers Now
“...members of the Diuk-Wasser lab found huge numbers of them on the bodies of unconscious deer that had been captured and anesthetized by wildlife authorities.”

New Travelers on Wildlife Corridors
"The easier it is for deer to maneuver through urban landscapes between parks, the more likely the ticks are to spread to new areas. This suggests that the emphasis on urban wildlife corridors has a previously unappreciated downside for human health."
