Asian Longhorned Tick found in Morgan County

– Chris Penrose, Professor & Extension Educator, Agriculture & Natural Resources, OSU Extension, Morgan County

I became disheartened a few weeks ago after I sent a bunch of ticks to a lab on campus to get identified and they confirmed what I feared: that we have the Asian Longhorned tick here in Morgan County. If I am correct, that makes five types of tick we likely have present in the county and many parts of Ohio. Ticks can give us Lyme Disease, Anaplasmosis, Rocky Mountain Spotted Fever, and a disease that makes us allergic to red meat.

Spot the Spot – Efforts Continue to Look For Spotted Lanternfly (SLF) in Ohio

Published on:
Spotted Lanternfly Adult
Recently, an Ohioan returned from a road trip to Pennsylvania. In addition to all the memories made, this traveler unintentionally brought back a hitch-hiker – a spotted lanternfly (Lycorma delicatula) (SLF). The individual quickly captured and ended the insect’s life before reaching out to his local Extension Educator. The suspect sample was submitted to the Ohio Department of Agriculture (ODA) for confirmation based on the USDA protocol established to confirm non-native pests not currently established, or with limited presence in the case of Asian Longhorned beetle, in the state.
SLF is well-known for its ability to hitch-hike into a new area within an already infested state, or in the case of Ohio, a state that is currently considered uninfested. If you are traveling to, or through, and infested area, you are encouraged to check your vehicle and any items that may have been outdoors during the trip (i.e., tents, camping supplies, recreational equipment). It is important to know that states have quarantines in place to limit the unnatural spread of SLF both within their state and other states and includes both any stage of the actual insect and any item that could move the insect (i.e., plant material, firewood, logs, outdoor furniture).

ASIAN LONGHORNED TICK CONFIRMED IN GALLIA COUNTY

Livestock Owners Encouraged to Examine Livestock Regularly and Report Suspected Findings  

REYNOLDSBURG, OH (July 31, 2020) –Ohio Department of Agriculture (ODA) today announced the United States Department of Agriculture’s National Veterinary Services Laboratory in Ames, Iowa, has confirmed that an exotic tick, known as the Asian longhorned tick, has been found in Gallia County.

The tick was found on a stray dog originating from Gallia County, which was later transported to a shelter in Canal Winchester. The tick was identified on May 28 by The Ohio State University and sent to the federal lab for confirmation.

“Due to the nature of this pest, the female ticks can reproduce without a male, so it only takes one tick to create an established population in a new location,” said ODA State Veterinarian Dr. Tony Forshey. “This pest is especially fatal to livestock, so producers should practice preventative measures and be on the lookout for this new threat.”

The Asian longhorned tick is an exotic East Asian tick that is known as a serious pest to livestock. U.S. Department of Agriculture first confirmed the presence of this tick in the U.S. in New Jersey in 2017.

Asian longhorned ticks are light brown in color and are very small, often smaller than a sesame seed. They are difficult to detect due to their size and quick movement. They are known to carry pathogens, which can cause disease in humans and livestock, and may also cause distress to the host from their feeding in large numbers.

In the United States, the tick has been found in or near counties with large horse, cattle, and sheep populations. To protect against infestations, farmers should check their livestock for ticks regularly. If producers spot unusual looking ticks or large infestations, report this to your local veterinarian or ODA’s Division of Animal Health at 614-728-6220.

Preventative measures such as keeping grass and weeds trimmed, in addition to clearing away brush on feedlots and pastures, can also help.

ODA state veterinary officials will continue to work with the U.S. Department of Agriculture and other federal and industry partners to determine the extent and significance of this finding.

Livestock producers and owners should notify ODA’s Division of Animal Health immediately at 614-728-6220 if they notice unusual ticks that have not been seen before or that occur in large numbers on an animal.

 

Spotted Lanternfly Continues to Develop

While the spotted lanternfly (Lycorma delicatula) (SLF) has not been detected in Ohio, the Ohio Department of Agriculture (ODA), along with the Ohio State University (OSU) and the Ohio Department of Natural Resources (ODNR) are urging Ohioans to continue to be on the look-out for this invasive insect. Many are using the Great Lakes Early Detection Network (GLEDN) App to report tree-of-heaven (Ailanthus altissima), a favorite food or host for this plant hopper, especially as an adult, and then revisiting the tree looking for signs and symptoms of SLF throughout the year.

Marsh Marigold Madness

On one of our jaunts through the woods and parks in NE Ohio, my wife was thrilled to see glorious blooms of intense yellows created by Caltha palustris or Marsh Marigold (MM).  The genus name “Caltha” is derived from the Latin meaning “yellow flower” and the specific epithet “palustris” means marsh-loving.  Therefore, the Latin binomial for this plant literally means “yellow flower marsh-loving”!!  This North American native plant thrives in bogs, ditches, swamps, forested swamps, wet meadows, marshes, and stream margins from as far east as Newfoundland to as far west as Alaska.  MM then slips down into Nebraska and then over to Tennessee and North Carolina and that is as far down south that it is able to tolerate the intense summer heat.

MM flowers are a cheery yellow and a welcome signal that Springtime is just around the corner!  In fact, MM is really NOT a marigold nor in the family, Asteraceae, the family to which marigolds belong, but it is a perennial in the Ranunculaceae or buttercup family.  Looking closely at the flowers, you clearly see the shiny, yellow, buttercup-like resemblance.  These plants may commonly be referred to as Caltha cowslip, cowslip, cowflock, or kingcup.

As an herbaceous perennial, MM prefers full sun to light shade and grows 1-2 feet tall and wide, with a naturally mounding growth habit.  The planting site would of course have to be consistently moist or even wet.  MM flowers are 1-2 inches in diameter, with 5-9 waxy, rich, golden yellow “petals”, which are really sepals, that appear in early Spring; specifically, they can bloom April to June depending on elevation, temperatures, and exposure to sunlight.

In fact, humans see MM sepals as yellow, but to insects, the outer half of the sepal is a mixture of yellow and the ultraviolet “bee’s purple”, while the inner most portion of the sepal is yellow.  MM flowers have anywhere between 50 to over 100 stamens.  The flowers offer an early source of pollen and nectar to insects, butterflies and hummingbirds, but they are most commonly pollinated by hoverflies (Syrphidae)!  MM can be propagated by either using “fresh seeds” (planting mature seeds immediately harvested from existing plants) or by dividing mature plants.

The more exposed MM are to direct sunlight in their site, the more quickly the soils will warm up and plants will bloom; conversely, the less exposure and more hidden or cooler the site, the flowers take much longer to mature and emerge.  While it is true that the best flowering will occur in full sun during the Spring, later in the season, especially during the heat of the summer, MM will do better if they have partial shade.  If sited in full sun in warm summer climates, the plants can actually go dormant with summer heat and dry conditions and drop their leaves!

MM’s have waxy, glossy green, basal leaves that may be round, oval, heart or kidney shaped and by mid-summer they may mature in size to about 7 inches across.  The leaves can have smooth margins or small scallops or teeth along the leaf margins.  The basal leaves of MM’s have long petioles with a deep, narrow sinus or notch where the petiole attaches to the leaf blade.  The upper leaves are alternate on thick, hollow stems with shorter petioles or no petioles at all and tend to be smaller than the basal leaves.

I found it fascinating that parts of MM are processed and used medicinally but handling the plant can cause skin irritation and blisters, and uncooked parts are toxic to humans.  WHAT?!  Now this is where plant research REALLY gets fascinating!  All plants of the buttercup family, Ranunculaceae, contain the toxic glycoside protoanemonin, sometimes called anemonol or ranunculol!  MM contains this yellow oil irritant, protoanemonin, throughout the entire plant, especially the older foliage and supporting plant parts.  Protoanemonin can be broken down or destroyed by heat!  Cattle and horses can be poisoned too by consuming raw or fresh MM, although dried plants, like those that may be found in hay, are no longer toxic to them!  That is so WILD!!  So, if you are outdoors and need to go on a buttercup binge, just look and enjoy these beautiful marshy, swamp loving plants but NO TOUCHY!!

Mining Bees Can Cause Minor Panic

By: Joe Boggs- Buckeye Yard and Garden OnLine – April 4, 2020

Last week, I came across one of the largest collections of soil “mining bees” that I’ve ever seen in Ohio. The “colony” was located in a picnic area and numerous males were making their low-level flights in search of females.  The sparse turfgrass coupled with early-evening lighting made conditions perfect for taking pictures.
