Tick Tock - A Timely Update on Ticks, Diseases and Prevention
Worried about ticks and the diseases they carry? Join us this Thursdays at 11:00 AM ET to learn what you need to know! Timothy McDermott of the Ohio Extension Service will cover both native and invasive ticks and how you can protect yourself against them.
All webinars will be recorded. Sign up to watch the live webinars or be notified when the recordings are posted. Please share this announcement with anyone you think might be interested!
CEUs will be available (CCH, ISA, SAF…)! Contact barne175@purdue.edu for more details.

Title: Tick Tock – A Timely Update on Ticks, Diseases and Prevention
Speaker: Timothy McDermott, Extension Educator, Franklin County, OH
Date: Oct 15th 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_60OjQpENQnyw5sj0pkBvsg
Abstract: This presentation will include a general background with a particular focus on the exotic East Asian tick, also known as the longhorned tick or bush tick. Tim McDermott, with Ohio State University, will cover where it is known to be in the US, what favorable conditions it prefers, and what you can do to protect yourself. First detected in 2017 in New Jersey, this summer, the tick was found in Ohio and Kentucky.
Title: What we know so far about how feeding and mating are related to spotted lanternfly flight dispersal behavior
Speaker: Tom Baker, Department of Entomology, Center for Chemical Ecology, Penn State University, University Park, Pennsylvania, USA
Date: Oct. 29th 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_aguLmFSASge46ja7WzbGZQ
Abstract: We have been studying the flight dispersal behavior of Lycorma delicatula in Pennsylvania for the past several years in order to determine whether there are any predictable directional and distance components to the flights that could help practitioners predict any new locations to which existing infestations might spread. At the peak of adult population abundance in 2017 and 2018 adults of both sexes were observed to launch themselves into the wind from all types of host and non-host trees or from porches, posts and other human-made structures. Analysis of these flights showed anemotaxis (wind-steering) was occurring before take-off in an “aim-then-shoot” pre-launch wind-orientation technique, but not necessarily during the flights themselves. The fairly straight-line-level or gradually descending flight trajectories allowed the flying adults to traverse only usually 10 to 50 meters of ground in one episode, showing no preference for landing on any particular species of plant or inanimate object. They would then crawl up a nearby vertical structure and launch themselves into flight again. Flying females showed strong visual responses to vertical silhouettes, turning and landing on telephone poles, light posts and tree trunks. Collection and dissection of hundreds of spontaneously flying females have shown that over 95% of them have not yet mated when in this flight-dispersal mode, and that they weigh less than sedentary poor-flying females in which dissections have proven they have already mated. The flight dispersal bouts undertaken by females seem to be related to their need to find new places to feed to complete sexual maturation and then mate.
Title: Lessons Learned from a Test of an Emerald Ash Borer Urban SLAM Program
Speaker: Clifford Sadof, Department of Entomology, Purdue University
Date: Nov. 5th 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_X0i9aeOuQcWevtQLMKYVRA
Abstract: Urban SLAM, or Slowed Ash Mortality, is an approach to managing emerald ash borer with fewer pesticides. Although this approach has been tested rigorously in the rural forests, operational tests of this approach are lacking in urban forests. In this webinar I will review the result of a six-year study that shows how the starting condition of the forest, ash species composition, density of trees, and choice of pesticide can influence the outcome of this approach.
Title: Dicamba/2,4-D & Trees: Old Herbicides Causing New Problems
Speaker: Robbie Doerhoff, Forest Entomologist, Missouri Department of Conservation
Date: Nov. 12th 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_bur56YPVQHqumRdxvKOMPA
Abstract: Dicamba and 2,4-D have traditionally been used during the early part of the growing season, when trees and other sensitive plants are still dormant. With the release of soybean varieties tolerant of these herbicides, summer applications are resulting in tree and native plant injury on a landscape level. This webinar will discuss the history of this issue and illustrate herbicide injury on trees.
Title: Invasive Jumping Worms: The Impact of a New Soil Invader
Speaker: Brad Herrick, Ecologist/Research Program Manager, UW-Madison Arboretum
Date: Nov. 19th 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_Il_EBoFaRB-oAo0NFkxUUg
Abstract: Jumping worms are invading forests and horticultural landscapes throughout the United States. These Asian earthworms modify soil structure and chemistry, nutrient dynamics, soil food webs, litter depth, and plant health. This talk will share information on general earthworm biology and identification, impacts, control options, and the latest research findings.
Title: Responses of non-native species to climatic change and their implications for management
Speaker: Sam Ward, Mississippi State University
Date: Dec. 3rd 11:00 AM ET
Registration: https://msu.zoom.us/webinar/register/WN_yP4jHkc2SHywVNH6SP1eQQ
Abstract: The establishment and subsequent abundance of non-native species, such as introduced pests and the natural enemies imported to combat them, is in part determined by the climatic suitability of the novel habitat. For non-native species that have been established for decades, shifting climatic regimes could cause deviations from historical patterns of abundance. I will discuss some potential mechanisms for how climate change might alter host-parasitoid dynamics, using the invasion of, and importation biological program against, larch casebearer in North America as a case study.
