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.

A paper titled "Quick Sex-Determination of the Asiatic Garden Beetle, Maladera formosae (Coleoptera: Scarabaeidae)" by Adrian Pekarcik, Scott Clem, Kyle Akred, and Kelley Tilmon was published November 2022 in The Great Lakes Entomologist. In this paper, authors identified a quick way to determine the sex of Asiatic garden beetle (AGB) adults. To successfully determine the sex of an AGB adult, one will need either a dissecting microscope - or even a hand lens in the field. Next, you need to look at the abdomen of the AGB and identify the pygidium, or last dorsal tergite.

It is the time of year where we start seeing stink bugs in our soybean fields. Stink bugs are a common pest of soybean. There are a number of different species of stink bugs in Ohio including the green, brown marmorated, brown, dusky, onespotted, and redshouldered. There are also predatory species of stink bugs that do not feed on soybeans; however, these are less common than the pest species.

One of the most common pests we monitor for in our Ohio Lepidopteran Monitoring Network is the Western bean cutworm (WBC). The WBC caught the attention of growers across the state around 2017, when it became apparent that the caterpillars were developing resistance to the Bt trait in corn that had previously provided protection.

A poster was developed to present virtually at the 2022 annual Entomology Society of America Meeting titled "A Bioassay Method to Evaluate Efficacy of Insecticides Against the Asiatic Garden Beetle". This posted was developed by Amy Raudenbush, Adrian Pekarcik, Chris DiFonzo, Zane Raudenbush, Jon Witter and Kelley Tilmon. The Asiatic garden beetle is a pest of corn in sandy soils. The grubs feed on the corn seeds and roots in early development causing the plants to be stunted or even die.

Over the past week we have seen an increase in Western bean cutworm (WBC) numbers across Ohio. For the week of July 10 - 16, 22 counties monitored a total of 74 bucket trap for WBC adult moths. Three counties in northwest Ohio, including Defiance, Henry and Lucas, were all above the number (more than 7 moths), that we recommend to begin scouting for egg masses (Figure 1).
