Perotis lugubris

Perotis lugubris is a species of beetle belonging to the family Buprestidae, commonly known as jewel beetles or metallic wood-boring beetles. As an agricultural and forestry pest, it is recognized for its ability to infest various woody plants, causing structural damage to the host species.

The beetle primarily targets weakened or stressed trees and shrubs. Its host range often includes ornamental species and specific forest trees. Because the larvae feed internally, the presence of the pest is often undetected until the host plant shows significant decline or branch dieback, which is a major concern for foresters and arborists.

The lifecycle of Perotis lugubris consists of complete metamorphosis: egg, larva, pupa, and adult. The females lay their eggs in bark crevices. Upon hatching, the larvae bore into the inner bark and sapwood, where they feed and develop. The adult stage typically emerges during the warmer months to mate and feed on foliage before starting a new cycle.

The damage caused by this pest is primarily vascular. By creating galleries in the cambium and wood, larvae disrupt the transportation of nutrients and water. This damage results in weakened plant vitality, leaf yellowing, branch death, and in cases of severe infestation, the death of the entire tree or shrub.

Effective management strategies against Perotis lugubris focus on prevention and sanitation:

• Regular inspection of trees to detect early signs of infestation.
• Removal and destruction of infested branches or severely damaged trees.
• Applying preventive insecticide treatments during the emergence period of adults.
• Improving plant vigor through proper irrigation and balanced fertilization.
