Xylota

Xylota is a genus of flies belonging to the family Syrphidae within the order Diptera. Unlike most members of the hoverfly family, which are predatory on aphids, Xylota larvae primarily have a saprophagous lifestyle. They inhabit decaying wood, damp rotting organic matter, and occasionally invade the living tissues of plants, causing significant structural damage.

This pest mainly affects weakened ornamental and fruit trees, as well as berry shrubs. A particular risk is posed by species whose larvae develop in the root zone or beneath the bark of young saplings, which leads to the disruption of nutrient flow and the eventual wilting or death of the host plant.

The life cycle of Xylota is closely linked to the accumulation of organic debris in the garden. Adult flies lay their eggs in bark crevices or moist soil areas rich in humus. The larvae develop inside decaying tissues, creating tunnels that become entry points for secondary infections, fungi, and harmful bacteria.

The nature of the damage is often disguised as other wood diseases. Affected parts of the plant begin to deform, while the bark darkens and peels away. In cases of massive infestation, young plants may die within a single growing season due to critical damage to the cambium layer.

Protection measures involve a comprehensive approach to the sanitary condition of the garden. The main methods of control include:

• Regular sanitary pruning and removal of infested branches.
• Clearing the garden of decaying wood and plant debris.
• Maintaining tree health to increase their natural resistance.
• Application of insecticides during periods of peak adult flight activity.
