Calophyidae
The family Calophyidae belongs to the order Hemiptera and the superfamily Psylloidea. These insects are highly specialized, often exhibiting a strong host-plant specificity, which plays a critical role in their distribution and the management challenges they present in commercial plantations.

Calophyidae
These pests primarily infest woody trees and shrubs. They are particularly recognized as significant pests of the Anacardiaceae family, most notably causing economic damage to pistachio orchards. Their impact is severe enough to warrant strict monitoring in major agricultural production zones.
The biological lifecycle of Calophyidae consists of the egg stage, five nymphal instars, and the adult stage. Females oviposit into the tissue of young shoots or leaves. The nymphs often develop either in the open or within galls, providing them with significant protection against environmental stressors and natural predators.
Typical damage includes leaf deformation, curling of the shoots, and premature defoliation. The feeding activity creates necrosis in plant tissues, which reduces the host plant's vigor and acts as an entry point for secondary bacterial and fungal pathogens, directly leading to yield losses.
Control measures rely on an integrated pest management (IPM) approach. This includes:
- Regular field scouting using yellow sticky traps to detect initial infestations.
- Sanitary pruning to remove infested plant parts.
- Application of systemic insecticides during the peak nymphal emergence window.
- Encouraging indigenous beneficial insect populations to suppress pest numbers.
