Acrogonia terminalis

Acrogonia terminalis is a species of sharpshooter leafhopper belonging to the family Cicadellidae (order Hemiptera). This insect is recognized as a significant agricultural pest due to its role as a vector for various plant pathogens, specifically those causing vascular diseases in woody perennials.

The primary hosts of this pest include citrus trees, coffee plants, and various ornamental species. Both nymphs and adults feed exclusively on xylem sap, which places extreme metabolic stress on the host plants and leads to reduced vigor and stunted growth.

The life cycle of the insect consists of an egg stage, five nymphal instars, and the adult stage. Development is highly sensitive to environmental factors such as temperature and humidity, allowing the pest to flourish in tropical and subtropical regions where host plants are grown year-round.

Damage caused by Acrogonia terminalis is characterized by direct injury from sap extraction and, more importantly, the transmission of bacterial diseases such as Xylella fastidiosa. Visible symptoms often manifest as leaf chlorosis, premature fruit drop, and extensive twig dieback, which severely limits the economic viability of the orchard.

Effective management strategies against this pest include:

• Rigorous field monitoring and trap placement to detect early infestations.
• Application of systematic insecticides to target nymphs and adults.
• Maintenance of clean orchard floors to remove alternative weed hosts.
• Implementation of biological control agents to manage local population surges.
