The Red Palm Weevil in the city of Bari: A first damage assessment

Abstract

Phoenix canariensis Chabaud (Canary Palm) is one of the most distinctive landscape elements of several coastal urban centers in Italy. However, over the past few years, international trade has increased the risk of the introduction of Rhynchophorus ferrugineus (Red Palm Weevil) in the country, causing the death of numerous plants. In this work we assessed the damage caused by the insect to Canary Palm in the City of Bari, Apulia Region, furnishing useful information to decision makers and communities for proper preservation measures in favor of this important urban-green resource. The findings shed light on effective and efficient spending strategies of public funds for urban green inside areas affected by the Red PalmWeevil, also based on cost-benefit approaches.
