Publication très récente sous la signature d’ auteurs célèbres comme HOODLE et FALEIRO on y trouve une analyse assez semblable à celle de l’ANSES. Intérêt du piégeage massif qui de surplus à un effet mobilisateur. Les insecticides ne sont pas écartés avec une préférence pour l’administration par le systèmes racinaire (soil drenching) de préférence à l’endothérapie. Les auteurs insistent beaucoup sur l’intérêt de la nouvelle stratégie “attract-and-kill” technique. Cela devrait nous inspirer dans les recommandations adressées à la DGAL.

Abstract
Urban areas landscaped with ornamental palms, especially Canary Islands date palms (Phoenix canariensis), are particularly vulnerable to incursion by invasive palm weevils, Rhynchophorus spp. (Coleoptera : Curculionidae). Metropolitan palmscapes are often resource rich in terms of palm species diversity and density, and these areas typically have numerous conduit (e.g., air, road, or sea transportation hubs) that assist with international and regional trade and tourism which can facilitate accidental or deliberate weevil introductions. Once established in urban areas, Rhynchophorus populations may be hard to suppress, from where they can expand their range and threaten agricultural commodities or native palms in wilderness areas.Here, we review current knowledge about relationships between Rhynchophorus invasions and urban environments. Further
research areas should be addressed to improve forecasts of invasion risks and to complement management options for detection and control. We propose that greater attention be paid to quarantine restrictions on live palm movements and pro-active early detection and monitoring programs in areas deemed to be at high risk of invasion and establishment. In response to an incursion, we advocate the deployment of containment and eradication campaigns in urban zones when populations are small and highly localized.
 

Conclusions
Palm weevil infestations affect the aesthetics of infested urban palmscapes and uncontrolled urban populations threaten agricultural (e.g., date plantations) and natural areas (e.g., palm oases). Accidental introduction of Rhynchophorus spp. into new areas has resulted in establishment and spread of these notorious palm pests in distinctly non-native habitats. Initial incursion detections are often in urban areas where weevils preferentially infest P. canariensis which is extremely vulnerable to attack and an excellent developmental host. Urban areas provide challenges for managing weevil infestations as infested palmsare often on private land which may complicate control programs. Inappropriate management planning, poor coordination between stakeholders, and public resistance to implementation of controls can adversely affect incursion management programs. Despite these difficulties, urban infestations can be dealt with effectively. Eradication is possible and success is largely predicated on strong longterm (i.e., > 3 years) public and institutional support of the management program (Hoddle et al. 2016). Failure to rapidly curb initial weevil establishment results in increasing size of area infested and rapid population growth, which jeopardize the success of eradication and containment programs.
