Ohio Maple Days 2022 did not disappoint.  The food was fantastic, the vendor room crowded, and the presenters shared a wealth of knowledge of expertise across a wide range of subjects. Dr. Curtis Young, Entomologist, Extension Educator, and Associate Professor, expanded our knowledge regarding maple pests.  Many that most of us were already aware of, spotted lanternfly or Asian long-horned beetle for instance, and lots of lesser known pests.  Before we get into a few highlights, be sure to mark your calendars for next year’s conference December 8th and 9th!

Any attempt to summarize Dr. Young’s talk would fail due to the sheer amount of information that he is able to share in such a short amount of time.  And no notes!  Truly a wealth of knowledge.  Rather than attempt a synopsis, this is a great opportunity to share some general resources and up-to-date information for some of the more alarming maple pests we face here in Ohio.

University of Kentucky Extension has a great webpage that quickly catalogs a wide range of known pests across 4 general categories – leaf feeders, sap feeders, borers, and galls.  While most maple pests are just that – pests, similar to how most of us view the average mosquito, a few present a real and present danger.  That said, if your maple trees are stressed already, a relatively harmless pest can be the proverbial straw that breaks a camel’s back.  Moral of that last sentence, practice healthy silviculture and sugarbush management to ensure your trees are healthy and vigorous.

Asian long-horned beetle are always mentioned in these presentations.  Thankfully, in Ohio at least, control and eradication of Asian long-horned beetle is a success story that we seldom get to herald in the fight against invasive species.  While we keep our eyes out for future infestations, spotted lanternfly has rapidly expanded its range and our state records now show several counties with positive detections.

An excellent website to stay abreast of issues facing plant, shrub, and tree health is Buckeye Yard & Garden onLine where Dr. Curtis Young and many other experts from Ohio State University Extension provide “timely information about Ohio growing conditions, pest, disease, and cultural problems.”
