Fidicina drewseni cicada

Fidicina drewseni is a large insect belonging to the order Hemiptera and the family Cicadidae. This species is a characteristic representative of tropical and subtropical fauna, with a life cycle closely associated with woody plants and forest ecosystems.

This pest primarily infests perennial woody crops, including fruit trees and ornamental plantings. In regions with warm climates, these cicadas can reach significant population densities, negatively impacting the physiological health and productivity of the infested plants.

The biology of Fidicina drewseni involves a prolonged life cycle, with the majority of its development occurring underground. Nymphs lead a subterranean lifestyle, feeding on plant root sap. Once the nymphal stage is complete, they emerge from the soil, climb onto tree trunks, and undergo their final molt into the adult form.

The primary damage is caused by females during the oviposition process. Using their sharp ovipositors, they create slits in young shoots and twigs to lay eggs. This causes mechanical damage, disrupts nutrient transport, and often leads to the dieback of the affected plant tissues. Additionally, adult cicadas feed on sap from vegetative organs, weakening the tree's immune system.

Control measures rely on a combination of cultural and chemical strategies. Key recommendations include:

• Regular pruning and removal of infested shoots.
• Application of targeted insecticides during periods of peak adult emergence.
• Maintenance of overall plant health to improve tolerance to infestations.
• Constant monitoring of insect populations to ensure timely intervention.
