Entomologist Uses 150 Beneficial Insects to Control Crop Pests — Here’s What Happens After 3 Weeks with a 40% Weekly Growth In a groundbreaking approach to sustainable agriculture, entomologists are turning to nature’s smallest allies to combat harmful crop pests. By introducing 150 beneficial insects into infested fields, farmers can replace chemical pesticides with eco-friendly biocontrol strategies. In one real-world trial, this approach showed remarkable promise—and the math behind its success reveals powerful growth. ### How Beneficial Insects Help Control Crop Pests Beneficial insects—such as ladybugs, lacewings, parasitic wasps, and predatory mites—act as natural predators or parasites to destructive pests like aphids, caterpillars, and mites. By releasing carefully selected species, entomologists create a self-sustaining ecosystem where pest populations are suppressed without harming the environment or beneficial pollinators.
