Pest Watch: Japanese Beetles

The Japanese beetle, Popillia japonica, has emerged to wreak havoc on your shade trees. Native to Japan as their name suggests, Japanese beetles are an invasive species that was first detected in the United States in 1916 (Rainbow Treecare, 2021). Due to its lack of predators in the US, it has been able to quickly spread through most states on the eastern side of the Mississippi River.

You can identify the Japanese beetle based on its iridescent and glossy appearance, with a green head and copper wing coverings. It has small tufts of white along the outside of its wing coverings.

The beetle feeds on over 400 species of shade trees and bushes (Rainbow Treecare, 2021). The beetle feeds by eating the leaf matter in between the leaf’s veins, leaving a skeleton-like appearance. If this happens to enough leaves, the beetles can easily kill your trees and shrubs, as the plant will no longer be able to photosynthesize. As well, the beetles send out a signal to other beetles in the area when they have found an acceptable plant host, sending more beetles into your yard.

So how do you get rid of Japanese beetles? One effective solution is a combination of a soil injection as well as a foliar spray to take care of any live beetles currently feeding on the leaves. It is important to begin foliar sprays at the beginning of adult feeding on plant matter, otherwise, the infestation can grow out of hand as more foliage is destroyed and more beetles come to feed. If you think you have a Japanese beetle infestation, please contact our office at 417-863-6214 and we can schedule a time for our Plant Healthcare technician to come to take a look at your trees and discuss your treatment options.

Where to See Fall Color in Missouri

Predicting the peak of fall color can be difficult. Missouri is blessed with a great variety of trees, shrubs, and vines. Their leaves turn at different times, so Missourians enjoy a fall color season that may last four to six weeks. Sassafras, sumac, and Virginia creeper are some of the earliest to change, beginning in mid-September. By late September, black gum, bittersweet, and dogwood are turning.

The peak of fall color in Missouri is usually around mid-October. This is when maples, ashes, oaks, and hickories are at the height of their fall display. Normally by late October, the colors are fading and the leaves beginning to drop from the trees. Fall color is usually finished by the middle of November.

The progression of color change starts earliest in north Missouri and moves southward across the state. Generally, the color change is predictable, but it can vary from year to year. Much depends on the weather.

Where’s the Best Place?

You can enjoy Missouri’s fall color almost anywhere.

For spectacular vistas, choose routes along rivers with views of forested bluffs, and along ridges with sweeping scenes of forested landscapes. In particular, the James River has spectacular fall sights.
On a smaller scale, drive on back roads, hike, or take a float trip under a colorful forest canopy on a clear, blue-sky day. Visit MDC Conservation Areas and Missouri State Parks.
Even treeless areas, such as prairies and roadsides, display beautiful shades of gold, purple, olive, and auburn with autumn wildflowers, shrubs, and curing, rustling grasses.
If you can’t get out of town, enjoy places with mature trees, such as older neighborhoods, parks, and even cemeteries.

Find events on your route

The Missouri Division of Tourism’s online calendar is packed with events happening all across Missouri this fall. Find those along your preferred routes.

Emerald Ash Borers : Pest 101

Be on the lookout for emerald ash borers. The emerald ash borer (EAB) is a serious threat to ash trees in Missouri. This invasive pest will eventually kill unprotected ash trees. Many trees can be saved with the careful use of systemic insecticides. However, not all ash trees should be treated, and for many locations the start of treatments should be delayed. This guide will assist you in making decisions about protecting your trees from this invasive pest. Find more information at eab.missouri.edu.

In the Ozarks, we are proud of our trees. But a small insect is putting our beautiful ash trees at risk. The emerald ash borer is an invasive pest that will eventually kill unprotected ash trees. Treating your tree early can help save it.

Here are a few signs to know if emerald ash borers have affected your tree:

D-shaped exit holes about 1/8″ wide.
Winding, s-shaped tunnels just under the bark.
New sprouts on the branches and lower trunk.
Increased woodpecker activity on the tree.
Sparse leaves and/or branches dying in the upper part of the tree.

To identify when is the best time to treat or cut your ash tree, check out this PDF from the Department of Conservation.

Jumping Oak Gall

Jumping Oak Gall FOREST HEALTH ALERT From the Missouri Department of Conservation

Tree species affected: White oak (Quercus alba) primarily, and some other white oak group species.

Concerns: Leaves on entire crowns of white oak trees turning brown in late spring. In some areas, whole hillsides appear brown.

Description: High populations of a very tiny, native, stingless wasp (Neuroterus sp.) cause pinhead-size galls (abnormal plant growths) to form on the undersides of leaves. Each round, button -like gall contains one wasp larva. Starting at the margins, brown, scorch-like areas appear on leaves where many galls are present. In more severe cases, leaves curl up, turn black, and drop early from trees. Effects of the damage become noticeable in late spring or early summer and remain visible until fall.

Most galls drop from leaves in early summer. Brown pockmarks remain where galls had been attached. Fallen galls are sometimes observed to “jump” due to vigorous movements of larvae within, much like moth larvae of “Mexican jumping beans.” This behavior allows galls to fall deeper into grass and leaf litter where they are sheltered throughout the coming winter.

Many species of gall wasps have two generations per year. It is assumed that the jumping oak gall wasp in Missouri has a similar life history with one generation lasting only a few weeks in early spring and rarely being noticed. The second generation extends from spring through the following winter and causes most of the leaf damage. Outbreaks typically last for one or two years and then fade away as natural controls reduce gall wasp numbers again.

Similar Leaf Issues: In years with cool wet springs, fungal diseases can be abundant on trees and may also cause leaf browning. Anthracnose is common on white oak foliage in those conditions. Botryosphaeria twig canker causes leaves on infected small branches to wilt and turn brown, which results in “flagging” in the canopy during the summer. Typically, twig bark shrivels and turns brown where the canker occurs, near the junction with healthy tissue.

Recommendations: Galls and fungi that affect oak leaves rarely have a significant impact on tree health. Nearly all trees will recover, even if all leaves are brown. Controls are not warranted. By the time the damage is observed, any opportunity to treat has already passed for that year, and populations are likely to decline naturally. However, severe leaf damage stresses trees, particularly if most leaves on a tree are killed which results in a second flush of leaves emerging in summer. The best tactic is using good tree care practices that reduce stress (mulching, watering during drought, avoiding wounds due to lawnmowers and trimmers).

Fun Facts About Trees

Dendrochronology is the dating and study of annual rings in trees.
General Sherman, a giant sequoia, is the largest tree (by volume) in the world, standing 275 feet (83.8m) tall with 52,000 cubic feet of wood (1,486.6m).
Leaves appear green because chlorophyll absorbs red and blue light energy, causing the green energy to bounce off the leaf’s surface.
Trees provide food and shelter for wildlife.
In one day, one large tree can lift up to 100 gallons of water out of the ground and discharge it into the air. Learn more tree facts.
Methuselah, an estimated 4,765-year-old ancient Bristlecone Pine, is one of the oldest living trees in the world.
Tree shaded surfaces can be 20–45°F (11–25°C) cooler than surfaces in direct sun, helping homeowners reduce summer cooling costs. Find out more about trees and the environment.
Consumers have a 12% higher willingness to pay for goods and services in retail areas that have streetscape greening such as street trees and sidewalk gardens. More on the benefits of urban greening.
Trees reduce stormwater runoff by capturing and storing rainfall in the canopy and releasing water into the atmosphere through evapotranspiration.
