Gilpinia pallida

Pine sawfly Gilpinia pallida

Description

Gilpinia pallida is a species of pine sawfly, commonly found in northern, central, and eastern Europe. It primarily targets pine species, with a strong preference for Scots pine (Pinus sylvestris). The adults are 6–8 mm long and are most active from May to July. The larvae of G. pallida feed on pine needles, causing defoliation that can lead to significant damage to forests during outbreak years. These outbreaks can coincide with other sawflies, such as Diprion pini, compounding the damage. During feeding, the larvae consume the needles, which reduces tree vigor and growth, and may lead to tree death if infestations are severe and prolonged.

Symptom

Symptoms include defoliation of pines, especially Scots pine, with needles being stripped from branches, leading to stunted growth, decreased vigor, and potential tree death during heavy infestations.
