Insect pest management in crops in the 21st Century is not about controlling 99.9% of the population with a pesticide. Agroecology from a pest managment standpoint is about designing crops that have the greatest level of bio-diversity to support the attraction and populating of pest predators, parasitoids and crop pollinators. Insecticides that reduce insect pests with minimal impact on beneficial insects are essential to farming in a modern world.
