Tyler Carr, Ph.D., Turfgrass Extension Specialist and Assistant Professor, recently shared some important information about turfgrass and drought stress. The inforamtion includes what you can do, and what's ahead.

2023 is shaping up to be “The Year of the Aphid.” At least, in southwest Ohio. I’ve already posted BYGL Alerts on aphids titled, Sticky, Dripping European Beech, and Sticky, Dripping Oaks. This Alert will be the third in the “Sticky, Dripping” series.

Overwintered Bagworm (Thyridopteryx ephemeraeformis) eggs are hatching in southwest Ohio meaning the “bagworm season” is now underway. Look closely at trees and shrubs festooned with last season’s bag abodes to detect newly hatched bagworms.

We held our OSU Buckeye Environmental Horticulture Team strategic planning meeting this week at Mohican Lodge and Conference Center. A hike in Mohican State Forest revealed that Yellow Poplar Weevils (Odontopus calceatus, family Curculionidae) are producing noticeable damage on their namesake host in that part of the state.

On a recent site visit, I noticed a Scots Pine that seemed to be bare. What was going on? European Pine Sawfly!

Dave Bienemann, Municipal Arborist/Utility Forester, City of Hamilton, alerted me to two pests appearing on river birch (Betula nigra) in southwest Ohio. Dusky Birch Sawfly (Croesus latitarsus) larvae are munching on the leaves while Spiny Witchhazel Aphids (Hamamelistes spinosus) are producing raised ribs or "corrugations" on the upper leaf surface.

Participants in last week’s OSU Extension/OGIA Diagnostic Walk-About held in Spring Grove Cemetery and Arboretum in Cincinnati came across an aggregation of Oak Treehopper (Platycotis vittata) nymphs on a mature white oak (Quercus alba). This treehopper is one of the more colorful members of the Membracidae family and behavioral studies have revealed a level of maternal care that’s unusual for a non-social insect.

Native ash trees in southwest Ohio are showing tell-tale symptoms of Ash Anthracnose. The disease is produced by the fungus, Plagiostoma fraxini (syn. Gnomoniella fraxini). As the specific epithet implies, the pathogen is specific to members of the Fraxinus genus.
