Soybean production in Minnesota is now threatened by multiple invasive insect pests. The soybean aphid (Aphis glycines), continues to be the most damaging insect pest of soybean. However, the Japanese beetle (Popillia japonica), is spreading and causing increasing injury to soybean. Growers need information about how co-occurring insect pests affect soybean yield to make better informed management decisions. The Koch lab has advanced drone-based scouting for soybean aphid, but we must understand how co-infestation by other insects like Japanese beetle affect spectral reflectance of soybean canopies. The work proposed here will evaluate the impact of combined infestation by both these pests...
