Lauritrioza alacris

Bay laurel psyllid

Description

Bay laurel psyllid Lauritrioza alacris is a species that develops on the leaves of Laurus nobilis (bay laurel), where it induces characteristic leaf-roll galls. Adults are 3.5–4 mm long with pointed wings and dark-tipped antennae. The life cycle is rapid, with several generations per year, especially in warm climates. Nymphs feed by sucking sap and secrete thick waxy substances inside the curled leaf margins, where they remain protected. Repeated infestations can lead to a high number of galls, which may reduce the ornamental value of host plants. This species is widespread in southern Europe and has expanded northward through trade and cultivation of bay laurel.

Symptom

Downward-rolled leaf edges forming tight tubes, often with white waxy deposits inside or brown exit marks.
