  6. New AGB Pocket Field Guide Available

    Dec 6, 2023

    A pocket field guide for the Asiatic garden beetle, written by Chris DiFonzo (MSU), Adrian Pekarcik (USDA-ARS), Kelley Tilmon (OSU) and Amy Raudenbush (OSU), is now available on our website. The Asiatic garden beetle (AGB) was first detected in the United States in 1921 in New Jersey, and has since spread to the Great Lakes region. In 2007, field crops growers in northern Indiana, southern Michigan and northern Ohio starting noticing stand loss - the culprit? AGB grubs. 

    In this guide, you will learn:

  7. New Caterpillar ID Card

    Nov 13, 2023

    Soybean defoliation is often noticed in soybean fields, and a lot of times, growers will notice multiple caterpillar species present along with the defoliation. Caterpillars feed on the soybean foliage as the plants grow. In Ohio, some of the most common caterpillars we find in soybean fields are the green cloverworm, soybean looper and silver spotted skipper. Also found are thistle caterpillars, woolly bear caterpillars and the saltmarsh caterpillar. Regardless of the species, they all feed on soybean foliage.

    Fall Armyworm Factsheet Now Available!

    Oct 10, 2023

    A fall armyworm factsheet, titled "Fall Armyworm in Ohio Field Crops" written for Ohio Line by Dr's Kelley Tilmon and Andy Michel is now available online! This factsheet discusses the lifecycle, management and treatment options available for fall armyworm in Ohio. Fall armyworm is not a yearly pest in Ohio, becasue it does not overwinter in our region. In fact, fall armyworm is considered It is a tropical species, that when high populations and the right weather events occur, migrates north. This event is known to reoccur every 3-5 years.

  10. By-catch in Fall Armyworm Traps

    Sep 7, 2023

    We have been noticing a number of moths in our fall armyworm (FAW) bucket traps that are not FAW, but rather a species of wainscot moth. These wainscot moths are accumulating in high numbers in the traps, and without proper identication, can be mistaken as FAW. While both moth species are in the same insect family, Noctuidae, FAW is an agronomic crop pest that requires monitoring, and the wainscot moth is not. Below are some images of both moth species.
