Ricaniidae

Crops damaged: Ricaniidae are highly polyphagous, meaning they feed on a diverse range of host plants. Major economic impacts are observed in vineyards, citrus orchards, various fruit-bearing trees, as well as ornamental plants and shrubs. Their ability to switch hosts allows them to maintain populations in various environments throughout the season.

Biology and life cycle: The life cycle progresses through the egg stage, five nymphal instars, and the adult stage. Nymphs are frequently observed with long, waxy filaments that provide protection and aid in camouflage. Adults are characterized by their distinct, triangular wing shape, often featuring complex patterns that help them blend into leaf surfaces.

Damage character and harmfulness: The primary harm caused by Ricaniidae is the extraction of phloem sap, which leads to stunted plant growth, chlorosis, and general weakness. Furthermore, the excretion of honeydew promotes the growth of sooty mold, which coats leaves and fruits, interferes with photosynthesis, and significantly reduces the marketable quality of produce.

• Systemic insecticides are effective during the early nymphal stages.
• Pruning and destroying heavily infested plant parts to reduce populations.
• Installing yellow sticky traps for monitoring adult flight patterns.
• Promoting biodiversity in the orchard to encourage natural predators.
• Implementing strict quarantine measures for imported plant material.
