Grub Season is Here!

Larvae and adults visible day after insecticide application at KC-area golf course.

Damage from white grubs has begun.  A Kansas City-area golf course exhibited significant damage to Meyer zoysia from white grubs (predominantly southern masked chaffer) in late June. It may seem earlier than normal, but if populations are high it can happen.  Grubs include southern masked chaffer, Japanese Beetle, and others.  Learn more about grubs and their control in an article by Dr. Raymond Cloyd by clicking HERE.

Bagworms and Eastern Tent Caterpillars

New useful posts on from the Department of Entomology:
Bagworms – It is Almost Time
We are getting close to the time when the 1/8 to 1/4 of an inch bags associated with the bagworm, Thyridopteryx ephemeraeformus, will be present on broadleaf and evergreen trees and shrubs. Therefore, be prepared to take action against bagworms once they are observed on plants. More details here:

KSU Insect Diagnostics – Digital samples

From the KSU Entomology News

In May of 2021, the Insect Diagnostics program was brought back into service in an all new digital format. Members of the public seeking assistance identifying an insect can access the Insect Diagnostics ID Request Form online. After providing observation information such as location and date of the sighting, followed by answering a set of questions intended to help with the identification process, one can then upload up to 3 photos and submit the form. The inquiry is then forwarded on to one of the entomology extension specialists. Within a few days, usually less than two, the identity of the insect along with appropriate life history information and/or control measures is then sent to the client by email or phone. The online submission process takes only a few minutes and can be accessed with desktop computers and mobile devices. If you need insect identification assistance, submit a request here:

Fall Armyworms are Back!

 

 

 

 

 

 

 

Fall armyworms have been spotted in the Wichita area, including the John C. Pair Horticultural Center.  Armyworms are foliar feeding caterpillars that can sever turfgrass tillers at the ground level.  Recovery is often good after the damage occurs, but be aware that if no attempt at control is used, turf quality will be low for a period of time.   Dr. Raymond Cloyd provides details about fall armyworms and their biology and control HERE!

Japanese Beetles

By Raymond Cloyd

This article is featured in the Kansas State University Extension Entomology Newsletter. 

Japanese beetle, Popilla japonica, adults are one of the most destructive insect pests of horticultural plants in landscapes and gardens. Japanese beetle adults are present throughout Kansas feeding on many plants including: roses, Rosa spp., littleleaf linden, Tilia cordata, oak, Quercus spp., Virginia creeper, Parthenocissus quinquefolia, apple, Malus spp., and grape, Vitis vinifera. The plant protection strategies implemented to manage Japanese beetle adult populations are limited, and have been for many years. The primary strategy has been spraying contact insecticides to kill adults, which will reduce plant damage.

Celebrating Pollinators Year Around

By Brooke Garcia

It was Pollinator Week June 21-27, 2021! How did you take part during Pollinator Week? Perhaps you had an encounter with a buzzy friend in the garden or planted some native perennials that attract pollinators in the landscape.

Celebrating pollinators does not need to be confined to one week only. You can do this in so many unique ways in your personal garden or landscapes you manage or oversee.

Photo taken in David Traylor Zoo of Emporia, KS by Brooke Garcia.

Here are some creative ideas to help attract and celebrate pollinators in our favorite landscapes:

  • Plant native flower beds, gardens, or local grasses to your landscape area
  • Add pollinator plants to flower pots
  • Incoporate native bee houses into the landscape
  • Host a pollinator plant sale or pollinator festival/event
  • Host an educational event with K-State
  • Choose a mixture of plants that flower during spring, summer, and fall
  • Reduce or eliminate pesticides in certain areas of your landscape if possible
  • Incorporate plants that encourage beneficial insects
  • Reach out to others and educate! Informing clients and friends is a great way to encourage change.

Here are some more ideas featured in the Extension Entomology Newsletter.

These are just a few ways to help support pollinators all year around! Have any pollinator topics you’d like us to feature? Email us at gardenhour@ksu.edu.
