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 Palm Weevil, also based on cost-benefit approaches.

Community preferences for the preservation of Canary Palm from Red Palm Weevil in the city of Bari. Arab Journal of Plant Protection, 37(2): 206-211.Rhynchophorus ferrugineus (red palm weevil) caused the death of 40% of Phoenix canariensis Chabaud (Canary palm) between 2011 and 2013 in the city of Bari. Extraordinary measures of compulsory pest control at EU and national level were applied, which however require public funds, hence proper cost-benefit studies, in order to favour better decision-making for urban green management. In this work, we investigated the preferences of the urban community towards specific measures for the preservation of Canary palm through a choice experiment. The results can be used to endorse the strategy in force and to shed light on effective and efficient prospective expenditures of public funds for areas affected by red palm weevil.
