Japanese Beetle

July first marks the beginning of the emergence of the Japanese Beetle in our region. This service alert is designed to give you more information about this pest and a few tips on how to mitigate the damage.

Overview

The Japanese beetle is a serious pest of turf, trees and ornamental plants, and a difficult species to attack due to the complex nature of its lifecycle.

The Japanese beetle begins its destruction as a grub or larvae living 2-3 inches below the soil. Grubs feed on grass roots, reducing the ability of the grass plant to take up enough water and nutrients to withstand the stress of hot, dry weather. As a result, large dead patches of grass develop, which can be rolled back like a carpet to expose the destruction. Grub infestation may also be indicated where crows, moles, and skunks are found to be digging up the soil while feeding on grubs.

In early July, the grubs grow into adult Japanese beetles and begin to emerge from the soil to feed, mate and lay eggs. By the Fourth of July, adult beetles will begin to feed on trees, vines and other ornamental plants. This activity typically continues for 6-8 weeks, during which more than 60 eggs will be laid.

Japanese beetles feed in full sun at the top of plants, moving downward as the leaves are consumed. At dusk, the females fly to the turf to lay eggs, burrowing about 2-3 inches below the soil. Grubs hatch a few weeks later, growing quickly and eventually growing to about an inch by late September. Most beetles pass the winter about 2-6 inches below the surface, and then begin feeding in April or May when ground temperatures begin to rise.

Where You’ll Find Them

Around the Fourth of July, Japanese Beetles will begin emerging from the ground and feeding on the leaves of Linden, Birch, Maples and Crabapple trees, as well as rose bushes and other ornamental plants. The beetles will be found feeding between leaf veins, making the foliage look similar to lace. The insects prefer to feed on the outer portions of the foliage where the sun is strongest.

Control Methods

Treating Japanese beetles can be complex due to the nature of the pest’s life cycle and the distances travelled by adult beetles. An effective treatment program may require the application of insecticide to both the trees and turf.

Turf applications can be applied in the spring when the recently overwintered grubs start feeding. However, these grubs can be difficult to kill due to their large size and ground applications are generally more effective when applied in early fall.

If damage is found to trees and ornamental plants, treating adult Japanese beetles is recommended in July and August. The presence of beetles on a plant attracts more beetles. Therefore, by not allowing beetles to accumulate, the plants and trees will be less attractive to other beetles - benefitting the trees and ultimately the turf. In circumstances with advanced infestation, multiple treatments may be required.

Any tree treatment for Japanese beetles should be combined with a fall grub control program so that the life cycle does not repeat itself the following year.

EAB Update

BENEFICIAL INSECT TO BE RELEASED IN JEFFERSON COUNTY TO HELP MANAGE EMERALD ASH BORER

DES MOINES – Beneficial insects that will help battle the emerald ash borer (EAB), a highly destructive pest of ash trees, will be released in Jefferson County. Over the next few weeks several thousand stingless, parasitic wasps will be released at Whitham Woods near Fairfield, Iowa. This is the first release of the natural enemies of EAB in Iowa.

When EAB was accidentally introduced into North America from Asia, its natural enemies, unfortunately, did not accompany them. This effort is being made to reunite pest and natural enemies to help suppress EAB populations. Following rigorous testing and research one or more parasitic wasp species, native to Asia, have been released in 23 of the 25 states where EAB has been detected. The parasitoids were produced and supplied by the USDA EAB Parasitoid Rearing Facility in Brighton, Michigan.

“Due to the current situation of EAB in and around Fairfield, biocontrol seems justified at this point in time, said Mike Kintner, Iowa Department of Agriculture and Land Stewardship EAB and gypsy moth coordinator. “The use of biocontrol will not be a ‘silver bullet’ for the problems we face with EAB, but the natural enemies will serve as a long-term management strategy to lessen the impact of EAB.”

The two species of parasitic wasps available by USDA Animal Plant Inspection Service target the larval and egg stages of EAB. Tetrastichus planipennisi female wasps, which are about the size of a grain of rice, lay eggs inside EAB larvae, terminating their development into adult beetles. Oobius agrili female wasps, which are the size of a gnat, lay eggs inside EAB eggs, parasitizing them before given the opportunity to hatch. Both species are harmless to people.

According to the USDA Forest Service, Iowa has an estimated 52 million rural ash trees and approximately 3.1 million more ash trees in urban areas. Additional suitable sites will be approved and utilized for biological control releases.

Mission Possible

In the post Maytag-era, Kim Didier and the team at DMACC Business Resources are investing in the future through a creative approach to economic development.

STORY BY NICK TAYLOR  |  IMAGES BY PHILLIP HARDER AND CHARLIE WITTMACK

Kim Didier moved home to Iowa 17 years ago with an infant in arms, a husband in tow and a new masters degree framed and ready to hang.  The gig that prompted the move from Indianapolis was a leadership role with the City of Newton, supporting employment at the City’s biggest employer, Maytag.  As she and her husband drove west, back to the arms of friends and family, life was full of possibility.

The Hall of Laureates

STORY BY EMMA LOCKWOOD | IMAGES BY NOLAN KRESNAK

By the mid-20th century, mass famine was imminent in certain regions of the world. In an effort to curb this pandemic, Iowan, Norman Borlaug, pioneered the introduction of a new variety of high-yielding, disease-resistant wheat. The increase in food production that resulted has been labeled the “Green Revolution” and Borlaug is often credited with saving a billion people from starvation.

Borlaug was awarded the Nobel Peace Prize in 1970 in recognition of his contributions to world peace through increasing food supply. He was subsequently also awarded the US Presidential Medal of Freedom and the Congressional Gold Medal, becoming one of only three Americans to ever have received these three highest honors.

Emerald Ash Borer is in Iowa

For the last several weeks local media has been reporting that the Emerald Ash Borer has been spotted in central Iowa. The Iowa Department of Natural Resources estimates that there are more than 3 million ash trees in metropolitan areas in Iowa and another 52 million trees in rural woodland areas. The expected loss of these trees could cost more than $2.5 billion over the next two decades.

This Service Alert will provide you with more information about the Emerald Ash Borer and treatment options that will save ash trees from destruction.
