Chestnut Sawfly Found on Hickory

Participants at last week's First Annual Tree and Plant Diagnostic Walkabout Workshop held in Lake Hope State Park in Vinton County, OH, came across a group of striking black-and-yellow striped sawfly larvae feeding on hickory. I had never see this sawfly before and after exhausting all of my usual routes for identifying tree pests, I followed the advice commonly given to me by seeking professional help.

Stinging Caterpillar Commentary boggs.47 Thu, 09/07/2017 - 14:14
I learned a valuable lesson during last week's First Annual Tree and Plant Diagnostic Walkabout Workshop held in the beautiful Lake Hope State Park in Vinton County, OH. If you want to find caterpillars, you should hike with Tom Macy, Forest Health Program Administer, with the Ohio Department of Natural Resources, Division of Forestry. Tom's cater-optic prowess is truly remarkable.

Gomphocarpus; The Balloon Plant chatfield.1 Thu, 09/07/2017 - 13:53
he late-season handiwork of the Basswood Leafroller (Pantographa limata, family Crambidae (Crambid Snout Moths)) clearly describes the unusual leaf-abodes created by this moth caterpillar. Individual translucent green caterpillars reside inside cigar-like nests created in a repeating three step process.

More Beech Diagnostics chatfield.1 Mon, 08/28/2017 - 17:07

American beech (Fagus grandifolia) is one of our most elegant woodland and parkland trees; it puts the sylvan in silviculture. There are many problems afoot, however, both large and small.

 

  For this alert, though, let us set aside the death and life realities of killer beech bark disease and the Boggsian itty-bitty bite/peench story of the beech blight (boogie-woogie) aphids (http://bygl.osu.edu/node/883). Let us look at...

Redbud Leaffolder Trekking Through Generations boggs.47 Mon, 08/28/2017 - 14:51
Last season, the unusual leaf symptoms caused by the Redbud Leaffolder on its namesake host were observed throughout Ohio. Questions regarding leaves turning brown after being folded over or "glued" together continued to come into Extension offices throughout September. This could be a repeat season based on what I've seen so far.

Attack of the Boogie-Woogie Aphids boggs.47 Mon, 08/28/2017 - 12:06
I posted a BYGL Alert on Beech Blight Aphids late last month and described their peculiar behavior that earns them the alternate common name of the "boogie-woogie aphid." I also noted they can be aggressive and will mass attack a threat. But, I didn't have first-hand experience with this behavior until this past Friday.

O Dodder, Where Art Thou? chatfield.1 Sun, 08/27/2017 - 13:19

  Well, on a recent odyssey to Pennsylvania, dodder was along a streamside bank, in small amounts amongst a lot of knot. Dodder as in Cuscata, a parasitic plant in the Convolvulaceae (morning glory family). Knot as in Japanese knotweed, or Fallopia japonica, touted as one of the most pervasive invasive weeds in the eastern United States.

Coneflower Cleanup boggs.47 Sun, 08/27/2017 - 11:59
Coneflowers have long been one my favorites in landscapes and naturalized areas because of their attractiveness to pollinators of all sorts. Of course, this is the time of the season when we may walk away from them as they start looking pretty rough. However, we should continue to focus our attention on detecting and managing two serious problems that will only get worse next season
