  1. Bean leaf beetle in soybeans
    Author(s): Kelley Tilmon , Author(s): Andy Michel

    At the end of the growing season, when many soybean fields are shutting down, those which are still green can be a magnet for certain insect pests as they leave the mature fields.  Double-crop soybeans and late planted beans that are running behind and are still fresh can be attractive for stink bugs, bean leaf beetles, and sometimes grasshoppers when they leave yellowing fields for greener pastures.  If you have such soybean fields in areas where other fields are maturing, they are worth an extra eye until they reach the R6 (full seed) growth stage.  After R6, the yield i

  2. red-phase bean leaf beetle with spots on soybean trifoliate

    The mid-season defoliators are beginning to show up in soybean fields across Ohio. These defoliators include first generation bean leaf beetles, Japanese beetles, grasshopper nymphs and several different caterpillars such as silver-spotted skippers, painted-lady butterflies and green cloverworms. Since all of these insects collectively add to the defoliation of soybeans, their collective feeding is used in the threshold to determine the need for an insecticide treatment, but it takes a lot of feeding to add up to significant damage. It often looks worse than what it truly is.

  3. Spider mite stippling damage in soybean (bugwood.org)

    As farmers progress with soybean harvest we encourage you to take a quick look at your grain quality, especiallyStink bug damage in soybean at field edges.  We have been receiving reports of the deformed and discolored beans typical of stink bug damage.  If your beans show signs of stink bug damage (or even if they don’t!) consider incorporating stink bug scouting into your managem
