Cicada

The genus Cicadetta belongs to the order Hemiptera and the family Cicadidae. These insects possess a specialized mouthpart called a rostrum, which is adapted for piercing plant tissues and extracting cell sap, causing significant stress to the host plant.

The pest affects a wide range of cultivated and wild plants. Cicadetta often causes damage to fruit trees, vineyards, and various cereal crops. Both adults and nymphs contribute to plant depletion by feeding on young shoots and leaves, which leads to stunted growth and reduced yields.

The biological life cycle of these insects is notably long and can span several years. The majority of the life cycle occurs underground, where the nymphs feed on plant roots. Adults emerge during the warmer months to mate and deposit eggs into the soft tissues of stems or branches, which can lead to further physical damage.

Typical damage symptoms include the wilting of shoot tips, leaf deformation, and a weakened overall plant immune system. Mechanical damage caused by egg-laying creates entry points for various pathogens, including fungal and bacterial infections that can lead to tissue necrosis or branch dieback.

Effective control measures require a strategic, integrated approach:

• Cultural practices: deep soil cultivation to disrupt nymph development.
• Chemical control: application of systemic insecticides during peak adult emergence.
• Monitoring: using sticky traps to detect infestation levels early.
• Sanitation: pruning and destroying infested branches containing egg clusters.
