L’objectif de la recherche est la présentation des contenus méthodologiques et des résultatspréliminaires du développement d'un GIS pour la gestion du problème la Processionnaire du Pindans le Parc National d'Aspromonte (Reggio Calabria, Italie). La dynamique de metapopulation duphytophage, nuisible pour l'économie forestière et la santé humaine et animale, a été analysée avec un échantillonnage intensif de la durée de 3 ans. Les données recueillies ont permis de produire une détaillée représentation de la dynamique de population de l’insecte. L’emploie detechniques d'analyse spatiale intégrée dans un GIS a permis l'élaboration de cartes de risque phyto-sanitaire et hygiénique. Le développement de modèles mathéMatiques et statistiques finalisé à l'évaluation comparative de stratégies d'intervention et à l'élaboration de décors futursd'infestation dont l'output est géré par le GIS est le fondement pour la création d'un Système de Support Décisionnel (DSS) avec lequel procéder à la gestion rationnelle des stratégies de contrôledu phytophage.
The aim of the present study has been to illustrate the methodological contents and the preliminary results related to the development of a GIS for the management of a forestal pest, the pine processionary moth, a defoliating insect, in the Aspromonte National Park, Calabria, Italy. The insect is harmful to the forest economy and causes allergic reactions in man and animals; its metapopulation dynamic has been analyzed through an intensive three years sampling. The data recorded have allowed a detailed representation of the pest dynamics. The use of spatial analysis techniques, integrated with a GIS, has permitted the elaboration of risk district maps for the evaluation of the pest impact on forest, human and animal health. In order to develop a Decisional Support System (DSS) mathematical and statistical models have been proposed for a comparative evaluation of strategies of intervention and for the elaboration of future scenarios of infestation.These DSS components are under implementation in the GIS environment to support the definition of rational control strategies for the management of the pest.

Abstract
The aim of the present study has been to illustrate the methodological contents and the preliminary results related to the development of a GIS for the management of a forestal pest, the pine processionary moth, a defoliating insect, in the Aspromonte National Park, Calabria, Italy. The insect is harmful to the forest economy and causes allergic reactions in man and animals; its metapopulation dynamic has been analyzed through an intensive three years sampling. The data recorded have allowed a detailed representation of the pest dynamics. The use of spatial analysis techniques, integrated with a GIS, has permitted the elaboration of risk district maps for the evaluation of the pest impact on forest, human and animal health. In order to develop a Decisional Support System (DSS) mathematical and statistical models have been proposed for a comparative evaluation of strategies of intervention and for the elaboration of future scenarios of infestation.These DSS components are under implementation in the GIS environment to support the definition of rational control strategies for the management of the pest.File | Dimensione | Formato | |
