Cicada

Systematic position: Cicadetta cantilatrix belongs to the order Hemiptera and the family Cicadidae. While they are known for their distinct songs, these insects can become significant pests in horticultural settings when population levels exceed natural thresholds.

Host plants: The pest primarily targets woody perennial plants, with a strong preference for pome and stone fruit trees, including apple, pear, and peach. They are also found on various deciduous forest trees, which can serve as a reservoir for infestation.

Biology and life cycle: The life cycle is complex and often spans several years. Nymphs remain underground, feeding on root sap, which goes largely unnoticed until adults emerge. Once adults emerge, they focus on mating and egg-laying, usually during the peak summer months, making the adult phase the most visible and potentially damaging stage.

Damage and economic impact: Damage is primarily caused by female cicadas during oviposition. They insert their sharp ovipositors into young, succulent stems, causing the twigs to split or wither. These wounds serve as entry points for bacterial and fungal pathogens, potentially leading to branch dieback and reduced fruit production.

Control measures: Integrated management includes several critical approaches:

• Regular pruning and removal of infested twigs containing eggs.
• Strategic application of insecticides during the period of adult emergence.
• Maintenance of healthy orchard conditions to improve tree vigor.
• Monitoring population levels using visual inspections and song detection during the adult season.
