Verde plant bug feeds on and may introduce cotton boll rot into green cotton bolls.  This feeding may result in at-harvest damage to the cotton lint.  Data from a field survey and controlled field cage experiments manipulating verde plant bug pressure were used to verify whether in-season insect density and/or green boll injury can be used to establish an action (boll protection) threshold for verde plant bug.
