To better prioritize scouting throughout the growing season, it helps to understand the relationships that occur between pests, conditions, and hosts. In Episode 6 of Corn College TV Season 3, Farm Journal’s Associate Field Agronomist Missy Bauer explains the Pest Triangle and how it can help scout insects more efficiently.
For example, it may take a certain species so many heat units until it will hatch. Using weather stations will help monitor those units so that the proper insecticide can be applied at the right time. Bauer says, "Understanding the life cycle of the different insects that we have is very helpful to key in on timings and conditions."

Evaluating weather conditions is essential in pest control.
Understanding the host is also an important factor in timing. With many different hybrids available, knowing which varieties are susceptible to which pests will help with the prediction process.
"Insects are probably one of the most predictable things that we have to deal with out in the field," says Bauer. She stresses the need to make accurate predictions. "Be proactive, not reactive."
