Book excerpt: An increasing cultural practice in soybean, Glycine max (L.), production is the use of winter annual cover crops before planting. Species of grasses, legumes, and forbs are planted for many agronomic purposes during the fall months. In the spring, cover crops are killed and soybean planted into the residue. When the termination of the cover crops is delayed for longer lasting benefits, insect pest issues can arise. The movement of insect pests from cover crops to subsequent cash crops happens through a connection known as the “Green Bridge”. Pests found in cover crops such as the pea leaf weevil, Sitona lineatus L. (Coleoptera: Curculionidae), can be particularly damaging to immature soybean plants. Experiments were conducted to tests how cover crops influence insect populations in soybean. Also, various chemical control options, soybean planting populations, and the timing of cover crop termination prior to planting were tested in these cover crop-soybean systems. Lastly, an experiment was conducted to measure how various species of cover crops and neonicotinoid seed treatments affect arthropod diversity in soybean fields.
