Leucaspis lowi

Löw's pine scale

Description

Leucaspis lowi is a sap-sucking scale insect primarily found on coniferous trees, especially various species of pines (Pinus spp.) and occasionally Abies and Taxus baccata. It feeds on the needles, causing discoloration, yellowing, and premature needle drop. Depending on climatic conditions, it produces one to two generations per year, overwintering as second instar nymphs, adult females, or occasionally as eggs. Females lay about 25 eggs, and crawlers disperse to new needles or are transported by wind, animals, or human activity.

Infestations reduce tree vitality and aesthetic appeal, especially in parks, gardens, and urban areas. Heavy infestations may weaken trees over time, leading to reduced growth and increased susceptibility to other stress factors. Leucaspis lowi is distributed across Europe, with higher activity in warmer regions and is considered an occasional pest in Central Europe.

Symptom

Infested needles turn yellow, dry out, and drop prematurely. Scale covers, up to 2 mm long, are visible on the upper side of young needles, giving the surface a rough texture.
