Pissodes validirostris

Pine cone weevil

Description

Pissodes validirostris, commonly known as the pine cone weevil, is a small beetle from the Curculionidae family, primarily infesting various species of pine (Pinus). Its hosts include Pinus sylvestris (Scots pine), Pinus nigra (black pine), Pinus mugo, Pinus pinea, and others, but it does not infest Pinus cembra. The larvae bore into pine cones, where they feed on the seeds, causing gall-like deformations. These cones become malformed, often curved, and drop prematurely before winter. The larvae, which are legless, pupate within the gall-like cone. This species is found in Europe, and other regions with significant pine forests. Despite the visible damage to cones, the overall economic impact is generally low due to the minor seed loss.

Symptom

Infested pine cones are malformed, often curved, and fall early. Small, round exit holes may be visible once the adults emerge.
