Acanaloniid planthoppers

Host range These insects are polyphagous, meaning they feed on a broad variety of botanical families. Economically significant damage is often observed in vineyards, various fruit trees, ornamental shrubs, and vegetable crops. Their ability to switch between different host plants makes them a persistent threat throughout the growing season.

Biology and life cycle The life cycle involves an egg stage, several nymphal instars, and the adult stage. Nymphs typically produce waxy secretions that act as a physical shield. Adults are mobile and capable of jumping or flying short distances, allowing them to colonize new plant parts quickly during the spring and summer months.

Damage and pest status The primary damage is caused by the extraction of plant sap, leading to stunted growth and reduced yields. Furthermore, the excretion of honeydew promotes the growth of sooty mold, which covers the leaf surface, blocks photosynthesis, and diminishes the aesthetic value of ornamental plants and the quality of edible produce.

• Implement yellow sticky traps to monitor adult flight activity.
• Use horticultural oils or insecticidal soaps for early instar nymph control.
• Apply systemic insecticides during high infestations to ensure effective coverage.
• Promote natural biological control by conserving predator populations like lacewings and spiders.
• Practice thorough weed management to eliminate alternative host plants in the field.
