From pests to pollinators, insects make an impact.

Few groups of animals touch our lives like the insects. Beneficial insects are at the foundation of the world’s ecosystems. Our agriculture is both dependent on insect pollination and vulnerable to insect attack. We are indebted to the insects and the services they provide, and yet we must spend billions to control the handful of insect species that are hazardous to our health, crops, and natural environment. For better and worse, we live in an insect world.
