Effects of variety and management practices on mite species diversity in Italian vineyards
Bulletin of Insectology 62 (1), 53-60
Abstract: The influence of grape variety (Fiano, Nero d'Avola, Refosco, Verdicchio) and vineyard management (conventional, organic and untreated) on mite diversity was investigated in important Italian vine growing areas over three years. The analysis focused on Phytoseiidae and Tydeidae, which were the most diverse and numerous mites observed. Eleven phytoseiid species were collected. Kampimodromus aberrans (Oudemans), Typhlodromus exhilaratus Ragusa, Typhlodromus pyri Scheuten, Amblyseius andersoni (Chant) and Phytoseius finitimus Ribaga were detected on all four vine varieties. The highest densities of the first two species were observed on Verdicchio, while T. pyri and A. andersoni were mainly found on Nero d'Avola. Only A. andersoni, T. exhilaratus and P. finitimus were recorded in all types of vineyard management. K. aberrans and T. exhilaratus were most abundant in untreated vineyards while T. pyri populations were much higher in the organic ones. Among tydeid species, Tydeus caudatus (Dugès), Tydeus californicus (Banks) and Pronematus ubiquitus (McGregor) were the most frequent. No differences were detected between the biodiversity indexes of the four vine varieties, while these indexes were different in the management experiment: biodiversity was higher in organic and untreated vineyards than in conventional ones. The correlation between mite group densities was evaluated.
