Kissophagus

Kissophagus is a genus of beetles belonging to the Curculionidae family, within the Scolytinae subfamily (bark beetles). Systematically, these insects are specialized dendrophages that infest woody species. They are closely associated with specific tree varieties, utilizing their tissues for feeding and reproduction.

The main crops damaged by Kissophagus are various types of fruit and ornamental trees, particularly those from the Rosaceae family. The damage manifests as a weakening of the tree's health, making it highly susceptible to secondary infections and infestations by other pests.

The biology and life cycle of Kissophagus are typical for members of the bark beetle subfamily. The adults bore into the bark, where the larvae then develop. The entire life cycle occurs within the woody tissues, creating a protected environment for the insect throughout most of its life stages, which complicates the early detection of the pest.

The nature of the damage involves the creation of complex galleries of maternal and larval tunnels beneath the bark. This disrupts the normal flow of nutrients and moisture within the plant, leading to the drying of branches, yellowing of foliage, and eventually the death of specific sections or the entire tree during mass outbreaks.

Protection measures against Kissophagus include a comprehensive approach aimed at maintaining orchard health:

• Regular monitoring of tree bark for the presence of entry holes.
• Timely sanitary pruning and disposal of infested branches and trunks.
• Application of authorized insecticides during the period of peak adult flight.
• Adherence to agricultural practices that enhance the natural resistance of the plants.
