Tetralicia

Tetralicia is a genus of insects within the Aleyrodidae family, commonly known as whiteflies, belonging to the order Hemiptera. These tiny pests are specialized sap-feeders, often found in ornamental forestry and specialized plant nurseries where they can significantly impact plant health.

The host range of Tetralicia typically includes various evergreen shrubs and broad-leaved woody plants. Due to their preference for the underside of leaves, infestations often go undetected until significant damage to the plant's vitality becomes apparent to the grower.

The biological cycle consists of eggs, nymphal stages, and the adult phase. Eggs are deposited on the foliage, and after hatching, the nymphs anchor themselves to the leaf surface to feed. The climate-controlled conditions often found in greenhouses accelerate their reproductive rates, leading to multiple generations per season.

Damage is characterized by chlorosis, stunted growth, and leaf curl caused by direct feeding. Furthermore, the secretion of honeydew promotes the growth of sooty mold, which coats the foliage, interferes with photosynthesis, and reduces the plant's aesthetic and commercial value.

Control measures require a multi-faceted approach. Monitoring for early signs of infestation is critical for management. Chemical control involving systemic insecticides is effective, while cultural practices such as improving airflow and sanitation help reduce population pressure within the environment.
