I got invited to SERF (ISU Southeastern Research Farm) field day last week to highlight corn rootworm management. I was easily distracted when it wasn't my stop and started walking around soybean plots looking for insects. [this is a common occurrence with entomologists!] Soybean was in various stages of senescence around the farm as you could imagine with multiple maturity groups used for research projects. I was surprised by the variety of insects still present the first week of September. Of course, insects feeding directly on the maturing pods are of greatest concern during R6-R8 (e.g., bean leaf beetle, grasshopper, stink bugs). Highlights of insects I could find are included in a photo mashup below.
