What organisms may be killed if a farmer sprayed insecticides?

When a farmer sprays insecticides, not only targeted pests but also beneficial organisms can be adversely affected. This includes pollinators like bees, natural pest predators such as ladybugs, and other non-target insects, as well as aquatic organisms if runoff occurs. Insecticides can disrupt local ecosystems, leading to a decline in biodiversity and the potential collapse of food webs. Additionally, some insecticides can harm terrestrial wildlife and even humans if they enter the food chain or water supply.
