Spotting the Spot – Spotted Lanternfly Outreach and Engagement 

Amy Stone, Extension Educator, The Ohio State University 

Date: November 4th, 11:00 AM ET 

Length: 1 hour  

Link: https://msu.zoom.us/webinar/register/WN_nMOCjTe-R9GuTIEJ7NX3uQ 

From the basics of ID to the importance and value of understanding how to report and two steps in the engagement process for spotted lanternfly and other invasive species. Learn how Ohio is transitioning from a spotted lanternfly uninfested state, to a couple non-contiguous counties with reproducing populations, with likely more to come. Amy will share how to engage the public, green industry professionals and others in the search for the spotted lanternfly. Sometimes a message in one state doesn’t necessarily work for another and may even cause some confusion. We will sort it out and stress the importance of everyone looking to spot the spot – Spotted Lanternfly Outreach and Engagement! 



Managing Invasive Forest Pests: A Futile or Fertile Effort? 

Andrew (Sandy) Liebhold, Research Entomologist, US Forest Service 

Date: November 18th, 11:00 AM ET 

Length: 1 hour

As more invasive forest pests arrive at our shores each year, it is easy to wonder if all the efforts taken against them are worth the time, effort and money.  In this webinar, Dr. Sandy Liebhold, US Forest Service Entomologist will draw on over 4 decades of experience to share his insights on responses ranging from border inspection and eradication efforts to slowing the spread of invasive pests. His unique perspective will help you understand the role of common tools and how you can best utilize it in your own fight against forest invasives. 



Detecting, Identifying and Managing Box Tree Moth 

Jen Llewellyn, Nursery and Landscape Specialist, Ontario Ministry of Agriculture, Food, and Rural Affairs 

Date: December 2nd, 11:00 AM ET 

Length: 1 hour 

Link:  https://msu.zoom.us/webinar/register/WN_nIpcTpTTTgKrvQVnt315Kw 

Jen will provide an in depth training for professional horticulturalists on the detection, identification and management for this new invasive insect pest of boxwood, the Box Tree Moth (Cydalima perspectalis).  Attendees will come away from this webinar with the ability to more confidently scout for this moth pest as part of the larger local detection and surveillance efforts in your region. 



Breeding for EAB-Resistance: What Does the Future Look like for Ash? 

Jennifer Koch, Research Biologist, US Forest Service 

Date: TBD 

Length: 1 hour

The invasion of emerald ash borer (Agrilus planipennis) threatens the survival of ash trees (Fraxinus) in the United States, where it is a common hardwood species especially in riparian and wetland forests.  Ash was also used extensively for soil conservation (including wind breaks) and in urban green spaces and streets. Surviving, or “lingering”, ash trees that had maintained healthy canopies for at least two years after all other large ash trees had died were identified in natural forests long-infested by EAB. EAB egg bioassay experiments confirmed that these trees possess an increased level of resistance due to several types of defense responses, including mortality of early instar larvae, larvae with significantly lower weights, or leaves less preferred for feeding by EAB adults.  Lingering green (F. pennsylvanica) and white ash (F. americana) trees have been accessioned and tested using the egg bioassay, and are now established in a field test to assess longer-term performance.  Controlled cross pollinations have been used to produce full-sibling progeny from varied combinations of lingering ash parents.  Bioassay data show that some of the 2-year-old seedling progeny kill more EAB larvae than either parent, suggesting a tree-improvement program is likely to be successful in producing EAB resistant seed.  Longer term goals include combining the best performing progeny from many families into a second generation seed orchard, so that the seed produced may be used for restoration plantings.
