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.

Planting Trees Correctly

Yes, there are right and wrong ways to plant a tree.  By following correct planting practices, you can ensure trees will avoid a slow decline and possible death from several causes. This is especially important for trees, which can be a large, long-lasting, and worthwhile landscape investment.

Choose the right tree for the right site, not just a tree you like.  This means that it will be cold hardy in your area.  It also means that it will be adaptable to your soils and site.  A sugar maple near pavement and buildings may dry out with leaves turning brown, or show salt injury if near roads.  A pine tree will grow poorly on a heavy clay soil.

Consider trees for their function.  Perhaps it is just the beauty of a spring crabapple in bloom, and the fall fruits it produces for birds.  Native trees provide the thousands of insects that birds feed upon.  Picking fresh fruits from your trees provides incredible taste and nutrition, plus saves money over buying them.  Of course, trees can be used for windbreaks and summer shade.

Choose a healthy tree.  This is one that has a good amount of roots in proportion to the tops.  Beware of trees that have been recently dug from the wild with little or no preparation prior to digging.  Often you get what you pay for.  Obviously check for signs of leaf injury from pests or diseases or trunk damage from mishandling.  Local nurseries with trained professionals are your best bet usually for buying healthy and appropriate trees.

Beware of trees sold in many large national chain stores.  These usually have been grown in distant areas, and may not be acclimated to our area.  I have found ones at such stores with few roots, the pots containing stones to hold the plants upright.  If in doubt, gently pull the plant out of the pot and look at the roots.  If non-existent, too few roots, too small pot and root size for the plant top, or the plant is pot-bound, keep looking.

Fall is here and that means trees are releasing their fruits produced over the summer. For squirrels and other wildlife, this is a busy time. It is a busy time for us here at Secrest too.

Our staff and volunteers have been out collecting and cleaning various tree fruits to sow in the spring. Each year we receive questions on how to grow oaks, or buckeyes, or other trees from seed. Usually when someone plants an acorn or a buckeye it doesn’t grow simply because it didn’t receive the right conditions needed to germinate.

Spotted Lanternfly: States Urge Citizens to Report Sightings of Invasive Insect Hitchhiker

spotted lanternfly - Lycorma delicatula

First encountered in the United States in Pennsylvania in 2014, the spotted lanternfly (Lycorma delicatula) had spread to New York, Delaware, and Virginia by early 2018. The invasive insect threatens Tree of Heaven as well as grapes, hops, and fruit trees, and it has a penchant for hitchhiking. Anyone sighting spotted lanternfly is urged to report it to their state agriculture department or local extension office.

In the summer of 2014, in Berks County, Pennsylvania, a keen-eyed state Game Commission officer spotted an unusual insect congregating in an ailanthus tree. It was a large plant hopper, about an inch long, with distinctive spots and red hind wings. The officer followed his training and called it in. “He gave us a chance,” says Sven-Erik Spichiger, entomology program manager for the Pennsylvania Department of Agriculture.

It was a spotted lanternfly (Lycorma delicatula), a sap-sucking insect native to Asia. Just more than a month after this first report, Pennsylvania issued a quarantine in select counties in an attempt to restrict the spotted lanternfly’s movement. “From our perspective, this pest is quite frankly terrible,” says Spichiger.

In the summer of 2017, Spichiger visited a property where one or two spotted lanternflies had been seen, but the owner had recently reported there was no real infestation. That situation had changed rapidly. “I deal with all kinds of invasive pests throughout the state—that’s my job—and I have to be honest I was awestruck when I visited the site. I haven’t seen anything quite like that before. The only thing I can liken this to is a massive mayfly hatch off the river. It’s that uncomfortable to be standing around,” says Spichiger. “This pest has such a tremendous potential to breed and increase its population size that it can overwhelm individual properties and entire communities almost overnight.”

If Spichiger sounds alarmed, it’s because there is a lot at stake. The spotted lanternfly may have a preferred host—Tree of Heaven (Ailanthus altissima)—but it will also feed more than 70 other plant species, including grapes, hops, and fruit trees. According to the Pennsylvania Department of Agriculture: “This pest poses a significant threat to the state’s more than $28 million grape, $87 million apple, and more than $19 million peach industries, as well as the hardwood industry in Pennsylvania, which accounts for nearly $17 billion in sales.”

The U.S. Department of Agriculture agrees. In February 2018, it announced it was committing $17.5 million in emergency funding to stop the spread of the spotted lanternfly in southeastern Pennsylvania. This was after spotted lanternflies were reported in New York and Delaware in the fall of 2017 as well as Virginia in January of 2018. The new funding will allow the USDA’s Animal and Plant Health Inspection Service (APHIS), in cooperation with the Pennsylvania Department of Agriculture, to expand surveillance and control programs in an effort to stop the spread of spotted lanternfly and reduce its population in the core infested areas in Pennsylvania.

These adult spotted lanternflies (Lycorma delicatula) were filmed on grapes in the summer of 2017. At around the 13-second mark, one of the insects in the upper left can be seen repeatedly excreting a stream of honeydew. The large amounts of honeydew secreted by spotted lanternflies leads to growth of sooty mold, which can severely damage the host plant. (Video via Erica Smyers, Penn State Entomology Department)

Like other leafhoppers, the lanternfly feeds on plant sap, which damages the plant, but greater harm comes as a result of the honeydew that the insect excretes in abundance. This sweet, sticky fluid promotes the growth of sooty mold, which is extremely damaging to fruit crops. Thankfully, effective control measures exist for the spotted lanternfly, but most alarming about the pest is its potential as a hitchhiker.

Adult lanternflies can fly, but it may be the least mobile of their life history stages—their egg masses—that has the greatest potential for long-distance travel. Spotted lanternfly egg masses are inconspicuous, and females will lay them on virtually any surface: trees, lumber, yard furniture, vehicles. Combine that with the fact that their preferred host plant, ailanthus, is an invasive itself that tends to grow in disturbed areas such as around parking lots or along highways and railroad tracks. Ailanthus is already growing in 44 states. Female Spotted lanternflies that are ready to lay eggs tend to be lazy, dropping onto the nearest convenient surface and depositing roughly 30 to 50 eggs.

Spichiger envisions a coal car stopped on an ailanthus-lined railroad track or an out-of-town pickup truck parked next to an ailanthus at a football stadium. A gravid female lanternfly drops down, deposits her eggs, and soon they are driven away to the next county or across the country.

Containing and eradicating the spotted lanternfly will require awareness, not just among the agriculture and entomology communities but also among homeowners, outdoorspeople, and others. The Pennsylvania Game Commission officer that called in the first report of this pest gave pest control authorities critical time to mobilize against the spotted lanternfly, and more keen eyes will be needed.

Spotted lanternflies are generally easy to identify. Spichiger stresses that, if you spot a spotted lanternfly or any other unusual insect, always report it to your state’s department of agriculture or your local county extension office.
