Until other control options are developed, fields should be sampled before maturity for tunneling and live larvae. Fields with high percentages of infested stems should be harvested as soon as possible to avoid girdling and lodging. For more information and pictures of this pest see the publication MF2581, “The Soybean Stem Borer” www.oznet.ksu.edu/library/entml2/MF2581.pdf
