Planting System and Cultivar Influence Olive Key-Pests Infestation in an Olive-Growing Vocated Area Cutrone, Michele Maldera, Francesco Nicolì, Francesco Tarasco, Eustachio Hermoso Leon, Juan Francisco Romero, Agusti Camposeo, Salvatore Producció Vegetal Fructicultura 633 Traditional and intensive planting systems have paved the way for the phenomenon of intensification, with the super high-density (SHD) system being the most prominent. This system has demonstrated high levels of profitability due to both the reduction in production costs achieved through complete mechanization and a significant increase in olive oil production per hectare, stemming from the more efficient utilization of resources such as light, water, and nutrients. The aim of this study was to evaluate, in a vocated olive-growing area, the phytosanitary status of a SHD olive orchard compared to a traditional one (TRD). The research focused on six key olive pests, considering the interaction between planting systems and eight cultivars in a semi-arid environment. The comparative analysis of pest infestations across the two planting systems revealed significant and complex patterns in pest population distribution and intensity. Overall, the planting system appeared to be the main factor influencing pest dynamics. The SHD olive orchard exhibited the highest infestation levels of Otiorhynchus cribricollis, Palpita unionalis, and Bactrocera oleae. Conversely, in the TRD system, the highest infestation levels of Saissetia oleae, Euphyllura olivina, and Prays oleae were observed. Moreover, the study highlighted a less pronounced effect of cultivars on the prevalence of all monitored key pests. These findings underscore the potential for developing more sustainable and effective pest management strategies tailored to specific planting systems. Furthermore, the results contribute to advancing eco-friendly control approaches and improving pest infestation management practices. Additional research will be necessary to deepen the understanding of these key pests and their interactions within different olive-growing systems.
