The Danger of Overlooking Beneficial Insects

There is a proverb that says “The enemy of my enemy is my friend.”

Never is this more true than at the field level, nestled deep in the crop canopy, where beneficial insects are hard at work killing and eating crop pests. The tricky part, however, is that these beneficial insects can look a whole lot like pests. What’s more, beneficial insects can and do keep pest populations in check, but it won’t happen in one day as it will with an application of insecticide.
