Spotted lanternfly (Lycorma delicatula) is an invasive insect that threatens a variety of plant species, mostly woody plants. It has not yet been found in Wisconsin, but it is steadily moving toward us from the eastern United States. Both juvenile (nymphs) and adult spotted lanternfly feed by sucking sap from the stem, branches, twigs and leaves of host plants. This weakens the plant and can contribute to the plant’s death. Because spotted lanternfly impacts a wide variety of agricultural crops (like grapes and hops), nursery crops (like roses), and hardwood trees (like maple, walnut, willow, and poplar), it is a high priority pest in Wisconsin.

Wisconsin Forestry Center Seeks Industry Input

Posted on by patricialindquist

Researchers at the University of Wisconsin-Stevens Point are seeking the opinions of Wisconsin’s forestry professionals.

Researchers are conducting an online survey to understand the professional development and training needs of Wisconsin practitioners in fields including forest management, timber harvesting, forest products, and urban forestry. By participating, you will help inform the development of more relevant, accessible, and valuable training opportunities.

The survey should take approximately 15 minutes to complete, and your response is anonymous. Visit this link to participate and share your thoughts in their online survey. The deadline to participate is April 28. 

If you have questions related to this study, please contact Zoe Kaminsky, graduate research assistant, at zkaminsk@uwsp.edu.

Protect Oaks During Spring Clean-up

With the arrival of spring, the Wisconsin Department of Natural Resources (DNR) recommends protecting oaks from the often-fatal oak wilt disease by refraining from pruning, cutting or injuring oak trees from April through July.

The highest risk period for oak wilt introduction to a new site is in spring and early summer. Pruning and cutting oaks exposes living tree tissue beneath the bark to potential infection. The disease rapidly kills trees in the red oak group and weakens those in the white oak group.

Sap-feeding beetles spread the disease between oaks by carrying oak wilt spores from infected trees or firewood to fresh, exposed tree wounds. Healthy oaks and freshly cut oak stumps can become infected as quickly as 15 minutes after a wound is made from a pruning cut or broken branch.

The Wisconsin Urban Forestry Council recently announced their annual awards honoring those dedicated to protecting, preserving and increasing the number of trees that line city streets, fill community parks and beautify neighborhoods throughout the state.

The Wisconsin Urban Forestry Council advises the Wisconsin Department of Natural Resources (DNR) on managing urban and community forest resources.

“Wisconsin plays a critical role in conservation, especially when it comes to trees! These awards honor individuals, organizations and communities for their hard work and dedication to trees and the benefits they provide,” said Linda Cadotte, Wisconsin Urban Forestry Council Award Committee Chair. “It’s an honor to learn more about the incredible work happening around our state that helps support healthy community forests.”

More Than 1,000 Wisconsin Municipalities Now Known To Have Emerald Ash Borer

Posted on by patricialindquist

In 2022, the number of municipal emerald ash borer (EAB) detections in Wisconsin crossed the 1,000 milestone. The 1,000th municipality (town, village or city) to have an EAB detection was the Town of Lincoln in Adams County on May 19. At the end of the year, EAB was known to be in 1,109 municipalities, up 23% from a year earlier.

First Anniversary Of Spongy Moth’s Name Change

Posted on by patricialindquist

March 2, 2023, marks one year since a new common name for Lymantria dispar, spongy moth, replaced the prior name of this insect, “gypsy moth.” This change was necessary because the word “gypsy” is an ethnic slur for the Romani people and the former common name equated people with insects. This is the first name change undertaken by ESA (Entomological Society of America)’s Better Common Names Project.

The current name—derived from the common name used in France and French-speaking Canada, “spongieuse“—refers to the moth’s sponge-like egg masses. Lymantria dispar is a damaging pest. This current name is a critical move in public awareness that focuses on an important feature of the moth’s biology while moving away from an outdated term. We encourage you to review any materials you may have on your website, ordinances and other material related to forest pests to ensure they are in accordance with this name change.
