Last week (6/26) we found high numbers of redbanded stink bugs (RBSB) on soybeans at the research station in Prattville. This invasive species is a little more aggressive and difficult to manage than the native species we are used to dealing with.
Although the red band on this stink bug’s back is its namesake, the key identifier is the spine on the ventral (belly) side of the abdomen. RBSB lay black barrel shaped eggs in two side-by-side rows. Early instar immatures are black with reddish markings and begin to turn greenish as they mature.
We will continue to monitor this pest and provide pertinent updates as the crop progresses.
Current recommended thresholds, insecticides and rates can be found in the Alabama Soybean IPM Guide.
