With the spotlight in the United States and elsewhere focused on invasive insects such as Asian longhorned beetle, emerald ash borer, and spotted lanternfly, it has been easy to overlook native insects that are also key pests in ornamental landscapes and urban forests. Native woodborers, in particular, can be very devastating and difficult to manage. By consuming vascular tissue under the bark of the trunk and main branches, borers sever the vital pipeline between the canopy and the roots, disrupting the essential movement of nutrients, water, and carbohydrates. In this article, author Daniel Herms discusses how wood-borer feeding impacts the health of infested trees and provides strategies for monitoring, preventing, and managing infestations of flatheaded and clearwing borers.
