Whitefly Identification in South Florida
Whiteflies are destructive plant pests commonly found throughout South Florida, especially in ornamental landscapes, gardens, greenhouses, shrubs, trees, agricultural crops, and residential properties with dense vegetation. These insects feed on plant sap and are known for causing yellowing leaves, plant decline, sticky honeydew buildup, and heavy infestations on ornamental and edible plants. Whiteflies are tiny winged insects with powdery white bodies that commonly gather underneath leaves in large numbers. The scientific classification for whiteflies falls within the family Aleyrodidae, and they are also commonly referred to as whitefly pests or plant whiteflies.
What Are Whiteflies?
Whiteflies are sap-feeding insects that damage plants by piercing leaves and extracting plant fluids.
Unlike chewing insects, whiteflies weaken plants through feeding activity and by producing sticky honeydew residue that encourages mold growth.
Large infestations may spread rapidly across ornamental landscapes and garden plants.
