The common pear psyllid ( Cacopsylla pyri ) is a well-known pest for arborists in France. This small, cicada-like insect causes significant damage to pear trees, ranging from general weakening of the trees to crop loss. This comprehensive guide helps you identify the symptoms, understand the pest's life cycle, and adopt effective control methods. At the end of the article, discover how Arboriverse, a specialist wholesale supplier, can help you restore your orchards.


Life Cycle of the Common Psyllid

Characteristics of the insect

  • Adult: Looks like a small cicada of about 2 to 3 mm, active from the end of winter.
  • Eggs: Elongated and translucent when hatched, they turn orange before the larvae are born.
  • Larvae: Go through five stages of development, gradually changing from yellow to flattened brown.

Annual schedule

The common psyllid can produce multiple generations each year, increasing pressure on orchards. Adults overwinter in orchards or nearby natural shelters, then lay eggs on buds in spring. The larvae emerge quickly, causing significant damage.


Damage Caused by the Common Psyllid

  • Direct impact on trees: Deformation of leaves and fruits, premature fall.
  • Honeydew and sooty mold production: Sticky honeydew promotes the appearance of sooty mold, reducing photosynthesis.
  • General weakening: Repeated infestations weaken the tree, making it vulnerable to secondary diseases.

Prevention of Common Pear Psyllid

  • Regulating tree vigor: Limit nitrogen inputs and practice careful pruning.
  • Promote natural auxiliaries: Encourage biodiversity to regulate psyllid populations.
  • Improve ventilation in the orchard: Adopt optimal tree spacing and avoid dense windbreaks.

Biological Control Strategies

  • Proactive monitoring: Regularly inspect trees for eggs or larvae.
  • Honeydew-targeting treatments: Use products like potassium soap and Heliosol.
  • Biodiversity management: Maintain a diverse environment to encourage natural predators.

Conventional Control Strategies

  • Winter ovicidal treatments: Apply specific products to destroy eggs before they hatch.
  • Reasoned chemical control: Prefer pesticides targeting only the Psyllid to protect predators.

Varietal Sensitivity

  • Vulnerable varieties: Some varieties like Williams are more sensitive and require increased monitoring.

Recommended Cultural Practices

  • Pruning: Regularly remove unnecessary suckers and branches.
  • Fertilization: Moderate nitrogen inputs to avoid excessive vigor.
  • Density: Respect an optimal planting density.
  • Sprays: Ensure even coverage when applying.

An Integrated Approach for Sustainable Management

Psyllid control relies on a combination of preventative, biological, and conventional methods. This integrated approach minimizes environmental impacts while ensuring sustainable yields. Proactive management is essential to maintain tree health and fruit quality.
