Whiteflies are small, winged insects that belong to the family Aleyrodidae. They are typically found on the undersides of leaves and can be recognized by their white, powdery appearance. These pests feed on plant sap, which can weaken plants and lead to yellowing leaves and stunted growth. In addition to causing direct damage, whiteflies can also transmit plant viruses, making them a significant threat to crops and gardens. Effective management strategies include introducing natural predators, such as ladybugs, and using insecticidal soaps to control their populations.
