Aleurocerus

Systematic position: The genus Aleurocerus belongs to the family Aleyrodidae (whiteflies) within the order Hemiptera. These are specialized insect pests frequently encountered in tropical and subtropical regions, causing significant economic damage to agricultural crops and ornamental plants.

Affected crops: This genus of pests most commonly infests a wide range of crops, including fruit trees, vegetable crops, and various ornamental species in greenhouses. It poses a particular threat to agricultural producers growing tropical fruits, where the insects colonize the undersides of leaves.

Biology and life cycle: The life cycle of Aleurocerus includes several stages: egg, nymph (several instars), and adult. Adult individuals are winged and capable of active dispersal within the field or greenhouse. Reproduction occurs rapidly under favorable temperature conditions and high humidity.

Nature of damage: By feeding on plant sap, the pests cause chlorosis, curling, and subsequent leaf drop. In addition, the insects excrete honeydew—a sticky substance that serves as a medium for the development of sooty mold, which inhibits photosynthesis and significantly degrades the market quality of the produce.

Control measures: Management of Aleurocerus requires an integrated approach.

• Monitoring pest populations using yellow sticky traps.
• Application of specialized systemic insecticides.
• Biological control using natural enemies, such as aphelinid wasps.
• Implementation of strict quarantine protocols for imported plant material.
• Removal of weed species that serve as alternative hosts for the pest.
