Soybean gall midge larvae have been detected in soybean in southeastern South Dakota. Scouting for fields with infestations may explain wilting or dying soybean along field edges. Unfortunately, there are no rescue treatments available to reduce soybean gall midge larvae populations. Soybean gall midge infestations typically begin with discoloration of the epidermis near the base of the stem.
