Aclees weevil

The genus Aclees belongs to the order Coleoptera and the family Curculionidae. These weevils are notable as significant wood-boring pests, primarily impacting various plant species, with a particular affinity for members of the Moraceae family, especially fig trees (Ficus carica).

In terms of agricultural impact, these insects are considered major pests. They target healthy and stressed trees alike, causing substantial damage to orchards and ornamental landscapes. Their ability to bore into the wood makes them difficult to manage using standard contact pesticides.

The biological cycle of Aclees involves the adult beetle feeding on green parts of the plant, while the larvae are responsible for the most severe damage. Larvae hatch from eggs deposited in the bark and proceed to tunnel deep into the xylem and phloem, disrupting nutrient flow.

Signs of infestation include the presence of frass (sawdust-like excrement) around the base of the tree, small circular emergence holes on the bark, and canopy thinning. Severe infestations lead to branch dieback, branch snapping during wind, and eventually the total decline of the host tree.

Integrated Pest Management (IPM) is essential for controlling Aclees. Strategies include:

• Maintaining tree vigor to improve natural defenses.
• Physical removal and destruction of infested branches to reduce local populations.
• Using targeted chemical applications during the peak adult activity season.
• Implementing strict quarantine measures on the movement of infested nursery stock.

Due to their cryptic lifestyle, early detection is the key to minimizing losses. Agronomists recommend monitoring tree trunks and branches for signs of larval feeding, especially in regions where the pest has recently been introduced or identified.
