MONITORAGGIO E RUOLO ECOLOGICO DEI SIRFIDI NEL PARCO NAZIONALE DELL’APPENNINO LUCANO VAL D’AGRI – LAGONEGRESE

Hoverflies (Diptera: Syrphidae) are functionally relevant insects in agroecosystems due to their dual role as pollinators and biological control agents. Adults contribute to the pollination of cultivated and wild plant species, whereas larvae, particularly those that are aphidophagous, naturally limit pest popula-tions. This study analyzes the composition and structure of Syrphidae communities along several transects within the Appennino Lucano Val d’Agri-Lagonegrese National Park (Potenza, Italy), selected on the basis of various environmental and structural characteristics of the vegetation. The comparison among transects highlighted variations in community composition in relation to habitat heterogeneity.
