Fungus weevil

Systematic position: Anthribus belongs to the order Coleoptera and the family Anthribidae, commonly known as fungus weevils. Unlike typical curculionid weevils, they possess distinctive anatomical features such as shorter and broader snouts, which adapt them specifically to their niche environments.

Host plants and damage: This pest is primarily associated with trees in orchards and woodlands. It targets the bark and cambium layers of fruit trees, frequently colonizing plants that are already stressed or compromised by fungal infections, such as cankers or mildews, which the larvae may also consume.

Biology and life cycle: The life cycle is tightly synchronized with the condition of the host tree. Adult weevils are attracted to damaged bark where they oviposit. The larval stage is spent entirely beneath the bark, where the larvae feed on plant tissues and fungal structures, creating intricate galleries that disrupt the vascular system.

Character of damage: Infestations result in the disruption of sap flow, leading to localized dieback of branches. The presence of the pest is often indicated by small emergence holes on the surface of the bark. Over time, heavy infestations can lead to structural decay and the death of the affected tree limb.

Control measures: Management strategies focus on sanitation and tree health.

• Regular pruning of dead or infected branches.
• Removal and destruction of heavily infested bark.
• Application of contact or systemic insecticides during the peak activity of adults.
• Maintenance of tree vigor through proper fertilization and watering.
