Lone Star tick

The lone star tick.

NEW HAVEN, CT (WFSB) - An aggressive human biting tick responsible for an array of diseases is rapidly expanding in Connecticut.

The Connecticut Agricultural Experiment Station reported more established populations of the lone star tick, Amblyomma americanum, in Fairfield and New Haven Counties.

The CAES noted the tick's potential for altering the dynamics of a myriad of existing and emerging tick-borne diseases in the state and throughout the northeast.

Previously limited to the southeastern U.S., the lone star ticks were detected in areas of the northeastern U.S. with no previous record of activity including Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, and Rhode Island.

However, established populations of the tick species have now been documented across most of southern New Jersey, Long Island, Fairfield and New Haven counties in Connecticut, coastal Rhode Island, and on Cape Cod and the islands.

According to Dr. Goudarz Molaei, a research scientist who also directs the CAES Tick Surveillance and Testing Program, the number of lone star ticks submitted to the CAES Tick Testing Laboratory increased by 58 percent from the period of 1996-2006 to 2007-2017, mainly from Fairfield County. Established populations of lone star ticks were discovered in Fairfield and New Haven counties in 2018 and 2019, respectively, and further establishment in New Haven County was documented on June 17, 2020.

CAES called the lone star tick an aggressive human biter with highly irritating bites. It has been associated with several human diseases and medical conditions, including tularemia, ehrlichiosis, rickettsiosis, Heartland virus disease, southern tick-associated rash illness, red meat allergy and likely the newly identified Bourbon virus disease.

“Rising global temperatures, ecologic changes, reforestation, and increases in commerce and travel are important underlying factors influencing the rate and extent of range expansion for ticks and associated disease-causing pathogens. It is anticipated that warming temperatures associated with climate change may lead to the continued geographic range expansion and abundance of the lone star tick, increasing its importance as an emerging threat to humans, domesticated animals and wildlife” Molaei said.

Depending upon the annual weather condition, adult lone star ticks are usually active from mid-March to late June, nymphs from mid-May to late July and larvae from July to September. It is important that the public develop a heightened awareness of the health risks associated with emergent tick vectors such as the lone star tick and their potential for changing the dynamics of tick-borne diseases in Connecticut and throughout the northeastern United States.

Another contributor to the surge in lone star ticks could be the uncontrolled release of over 100,000 radioactive lone star ticks on the Virginia coast from 1968 through 1969, during several Army-funded studies that tracked the spread of these ticks using a Geiger-counter device. The details of this release are presented in my book “Bitten: The Secret History of Lyme Disease and Biological Weapons.”

It’s easy to see how these aggressive, prey-stalking ticks may have hitched rides on birds as they few up the Atlantic Flyway. Lone stars were first discovered in established colonies on Long Island in 1971 and this species was probably responsible for the rapid spread of a deadly Spotted Fever outbreak during that decade. Additionally, in 1963, the military dumped infected ticks on Cuba, also on the Atlantic Flyway.

Not to worry. When that tick sees what a mess Connecticut is, it will move out as well.

Isn't it funny how everyone that b!tches about CT still lives here?
