Tetralicia iberiaca

Tetralicia iberiaca is a species of insect belonging to the Aleyrodidae family (whiteflies) within the order Hemiptera. While often overlooked compared to more common greenhouse whiteflies, it poses a specific threat to various ornamental and cultivated plants, utilizing a piercing-sucking mouthpart to extract plant fluids.

This pest is primarily observed on specific botanical families, often targeting shrubs and broad-leaved plants. It thrives in moderate climates, and its ability to colonize the underside of leaves makes it a hidden threat that can cause significant physiological stress to the host plant if left unmanaged.

The life cycle of Tetralicia iberiaca follows a typical hemimetabolous pattern, progressing through egg, larval (nymphal), and adult stages. The larval stages are particularly damaging as they remain sedentary on the leaf surface, feeding continuously, while adults are capable of flight, facilitating the spread of the infestation throughout the garden or nursery.

The primary damage symptoms include chlorotic spotting, leaf yellowing, and general stunting of plant growth. Furthermore, the secretion of honeydew by the insects serves as a substrate for sooty mold growth, which blocks sunlight from the leaf surface and further impairs the plant’s ability to perform photosynthesis efficiently.

To effectively manage populations of this whitefly, an integrated pest management (IPM) approach is recommended. This includes:

• Deploying yellow sticky cards to monitor adult flight activity.
• Applying systemic insecticides that provide long-lasting control.
• Implementing strict quarantine protocols for new plant stock to prevent introduction.

Cultural practices such as improving airflow and ensuring plants are not overcrowded also play a vital role in reducing the suitability of the environment for Tetralicia iberiaca. Regular scouting of the foliage is essential to detect early infestations before they reach economic threshold levels.
