TREE Fund announces “Invasive Insects of Shade Trees” webinar
TREE Fund announced that Dr. Whitney Cranshaw of Colorado State University will host a webinar titled “Invasive Insects of Shade Trees: A 30 Year Perspective from Colorado,” on May 2 at noon Mountain time.
Cranshaw will discuss the ever-changing cast of new and invasive tree insects that have become issues in the Rocky Mountain states during the past 30 years. Through human-assisted spread there has long been a constant flow of new insects colonizing the woody landscape plants of the Rocky Mountain/Intermountain West, involving species that are native to other areas of North America and those that are more exotic in origin. How well these new colonizers establish is often very different than in other regions due to differences in climate, geography, landscaping practices, and the mix of plants present. In this discussion we will provide a review of how various introduced species have developed – or in some cases failed to develop – as pests of woody plants over the past three decades in Colorado.
Cranshaw is a professor and Extension Specialist of Entomology at Colorado State University. For the past 34 years, he has conducted a broadly based program largely directed at questions involving arthropod pests affecting horticultural commodities in Colorado, including vegetables, shade trees, turfgrass and specialty crops. Much of his attention has involved projects of shade trees, shrubs, and woody plants, including the discovery and description of thousand cankers disease of walnut, drippy blight of red oak, and the occurrence of neonicotinoid resistance among European elm scale. This has resulted in the production of over 85 refereed publications and several hundred related to Extension and outreach. Among the latter include the books Insects and Diseases of Shade Trees in Colorado, Bugs Rule! An Introduction to the World of Insects and, most recently, Garden Insects of North America,2nd Edition.
One CEU available from ISA, SAF or NALP; must watch live broadcast to receive CEU credit.
Pre-registration is recommended. In doing so, you will receive a reminder email the day of the webinar.
Webinar will be archived within one week of broadcast at treefund.org/webinars.
