  2. Stink Bug Damage to Soybean
    Author(s): Andy Michel , Author(s): Kelley Tilmon

    As soybean harvest progresses, a few growers are noticing poor yields in otherwise nice-looking plants and pods. While a visual inspection might lead to high estimations of seed quality, the inside may contain shrunken, shriveled or, even worse, missing seed.  Stink bugs can often cause this type of injury to soybean seed. They have piercing sucking mouthparts that poke through the pod wall, and then feed directly on the seed. Because their mouthparts are small, damage to the pod is often undetected.

    We have been hearing reports of increasing numbers of Japanese beetles in corn and soybean, and sporadic infestations of various caterpillars in soybean.  Japanese beetles are large with a shiny copper and green color.  Foliage feeding in corn is almost never economic, though economic damage from silk clipping is possible (though rare).  Consider a rescue treatment when  silks are clipped to less than ½ inch and, fewer than 50% of the plants have been pollinated, and the beetles are still numerous and feeding in the field.

    Results from week four of The Ohio State University Western bean cutworm (WBC) monitoring network has resulted in an increase of moths captured in the majority of Ohio counties; which means now is the time to get out and scout for egg masses.  Last week’s trap count included WBC adults captured from July 15 – July 21. A total of 26 counties monitored 79 traps across Ohio. Overall, trap counts increased, resulting in a total of 2001 WBC adults (287 total last week) and a statewide average of 25.3 moths/trap (up from 3.8 average last week) (Figure 1).
