Which ecosystem service is most directly associated with predatory or parasitoid beneficial insects?

Predatory and parasitoid insects directly reduce pest populations by eating or parasitizing other insects that harm plants. This direct control of pests is what we call pest suppression. That’s their primary ecosystem service because it lowers crop damage and can lessen the need for chemical controls, benefiting plant health and yields. Pollination is a separate service tied to insects that move pollen between flowers, like bees and butterflies, and isn’t about controlling pest numbers. Erosion prevention involves keeping soils stable and vegetated, not the action of predatory insects. Water filtration relates to how ecosystems process and clean water, again not a direct role of these natural enemies. So the most direct service provided by predatory or parasitoid insects is pest suppression.
