Vane-winged cixiid

The vane-winged cixiid (Cixius nervosus) is an insect belonging to the order Hemiptera and the family Cixiidae. It is a widespread species in the Palaearctic region, commonly inhabiting orchards, forests, and various crop fields where it acts as a significant sap-sucking pest.

This species is polyphagous, targeting a wide range of woody plants and shrubs. Its primary host range includes economically important fruit trees such as apples, pears, cherries, and plums. It is also frequently found on forest trees, including oak and birch, which acts as a reservoir for the pest.

The biological cycle of the pest consists of one generation per year. The larvae overwinter in the soil, feeding on the roots of host plants. As the weather warms, they complete their development, emerge as adults, and migrate to the tree canopy to feed on foliage and young shoots throughout the growing season.

Damage caused by the vane-winged cixiid involves the extraction of plant sap, which leads to general weakening of the host plant. Infested leaves often exhibit yellowing, curling, and early senescence. Furthermore, these insects are known vectors for various phytoplasmas and viruses, potentially causing devastating diseases in fruit orchards.

Control and management strategies include:

• Maintaining weed-free conditions in orchards to reduce larval habitats.
• Application of systemic insecticides during the peak activity period of the adult stage.
• Deployment of sticky traps for monitoring and reducing the population of adult insects.
• Improving plant health through proper fertilization and cultivation to mitigate the effects of pest pressure.
