Pine turtle scale Scale insect infestation in expands across Italy

The pine turtle scale insect (Toumeyella parvicornis), a North American species that feeds on sap and causes needle loss and tree decline, parvicornis) infestation has triggered emergency phytosanitary responses expanded across several Italian regions. Italy, prompting new biological and financial calls for action. In Tuscany, the Regional Phytosanitary Service implemented measures in Abruzzo region, the Florence, Fiesole, outbreak has spread along the Teramo coast from Pineto to Silvi, Alba Adriatica, Roseto degli Abruzzi, and Sesto Fiorentino areas. Giulianova. In Pineto, a census identified 712 specimens, with 322 classified as severely compromised. Silvi has treated approximately 800 trees. Following investigations by official confirmation of the parasite, the Regional Phytosanitary Service and the Council for Agricultural Research and Economics (CREA DC), an updated Action Plan was issued. This plan includes eradication strategies within 100 meters of established 5-kilometer buffer zones around infested plants in the affected zone, while containment strategies will be applied to other areas where the infestation can no longer be eliminated. In other regions, areas. Enio Pavone of the infestation Azione group has led requested extraordinary financial support from the Abruzzo Region to direct municipal interventions. In Pineto, authorities ordered treatments for hundreds help municipalities cover the unanticipated costs of stone pines showing heavy needle loss mandatory monitoring, pruning, and branch desiccation, noting that specific climatic conditions have encouraged a fourth generation of the insect. waste disposal. In the Rome municipality, specifically in Ostia, Castel Fusano, Pisa, environmental associations such as WWF Alta Toscana and Infernetto, the infestation has reached a terminal stage Italia Nostra are advocating for many trees, necessitating the removal of dead or dying specimens urgent measures to ensure public safety. In Pescara, protect coastal and urban pine groves. They are supporting the situation has escalated into regional introduction of Thalassa montezumae, a local controversy. The association Radici in Comune has issued predatory coccinellid selected by CREA for biological control, following a formal warning to the municipality, with president Simona Barba describing world-first experimental release in Naples. To mitigate damage in urban settings, experts recommend endotherapy—injecting systemic insecticides or biostimulants directly into the infestation as plant’s xylem. Additionally, environmental groups are calling for a “massacre suspension of our largest trees.” Critics argue massive forestry logging, warning that local administration has failed to follow scientific protocols and regional directives established in 2021. The association claims current interventions are ineffective due to reinfestation from untreated trees machinery vibrations and is demanding comprehensive endotherapeutic treatments for all municipal pines by September 2026. the transport of unpeeled timber increase the risk of passive parasite dispersal.
