Asian Longhorned Tick Confirmed in Ohio

The Ohio Department of Agriculture (ODA) announced the United States Department of Agriculture’s National Veterinary Services Laboratory in Ames, Iowa, has confirmed that an exotic tick, known as the Asian longhorned tick, has been found in Gallia County.

The tick was found on a stray dog originating from Gallia County, which was later transported to a shelter in Canal Winchester. The tick was identified on May 28 by The Ohio State University and sent to the federal lab for confirmation.

“Due to the nature of this pest, the female ticks can reproduce without a male, so it only takes one tick to create an established population in a new location,” said Dr. Tony Forshey, ODA State Veterinarian. “This pest is especially fatal to livestock, so producers should practice preventative measures and be on the lookout for this new threat.” Continue reading Asian Longhorned Tick Confirmed in Ohio →

Get Ready for a Little Breaking and Entering

Our drop in temperatures throughout Ohio will no doubt convince fall home invading insects that it’s time to seek winter quarters.  These unwelcomed guests typically include Boxelder Bugs (Boisea trivittatus); Western Conifer Seed Bugs (Leptoglossus occidentalis); Magnolia Seed Bugs (Leptoglossus fulvicornis); Multicolored Asian Lady Beetles (Harmonia axyridis); and the most notorious of all, Brown Marmorated Stink Bugs (Halyomorpha halys).

Late-Season Pod Feeding by Bean Leaf Beetle or Grasshopper

By: Kelley Tilmon and Andy Michel, Ohio State University Extension, Previously published in the C.O.R.N. Newsletter

We have heard a few reports of either bean leaf beetles or grasshoppers increasing in soybeans. As we start to approach the end of the growing season the larger concern with these insects is the potential for pod feeding, rather than foliage feeding. Pod feeding directly impacts grain quality. Crop stage is also an important consideration. Continue reading Late-Season Pod Feeding by Bean Leaf Beetle or Grasshopper →

They’re back…Japanese Beetles on the Rise

This article was written to complement Celeste Welty’s blog on Japanese beetle insecticide selection last week (http://u.osu.edu/vegnetnews/2018/06/30/insecticide-notes/).

One of Ohio’s most recognizable leaf feeders, the copper-colored and metallic green Japanese beetle, is on the rise. According to scattered reports across the state, this beetle has been leaving a trail of skeletonized leaves on an array of landscape plants, field crops, vegetable and fruit crops.
