Small green lacewing

The small green lacewing (Chrysopa microphya) belongs to the order Neuroptera, family Chrysopidae. While the family is widely recognized for its beneficial predatory species, this specific member is documented as a pest capable of causing significant damage to horticultural and agricultural crops under favorable climatic conditions.

This species primarily attacks fruit trees, berry bushes, and various vegetable crops. By feeding on young buds, leaves, and tender shoots, the insect depletes the plant's resources, leading to arrested development and stunted growth, which ultimately affects the quality and quantity of the harvest.

The biological cycle consists of four distinct stages: egg, larva, pupa, and adult. Females deposit eggs on long stalks to protect them from competitors. The larvae are the most destructive stage, actively feeding on plant tissues before moving to sheltered areas on the trunk or soil to pupate during the winter season.

Damage is characterized by localized yellowing, necrotic spotting, and structural deformation of new growth. High infestation levels can lead to severe stress in the host plants, making them more susceptible to secondary fungal or bacterial infections that can spread rapidly throughout the orchard or field.

Integrated pest management strategies include:

• Early season monitoring using specialized sticky traps.
• Application of selective biopesticides during the larval stage.
• Sanitary pruning to remove overwintering sites for the insects.
• Encouraging natural biodiversity to maintain the ecological balance in the field.
