During this session, I will focus on sampling of two major insect pests of corn and soybeans, the western corn rootworm and the soybean aphid. These two insects are common pests that can cause tremendous economic damage to corn and soybean respectively. Determining what impact these pests have on their respective host plants requires sampling, which in turn requires understanding the biology of each insect. I will discuss basic types of sampling and the tools used to sample insects, within the context of corn rootworms and soybean aphids. The discussion will include trapping insects versus visual counts, how to relate insect abundance with yield loss, and where to find insect sampling tools.
