“…Xf is an aerobic bacterium [3], transmitted through xylem-sucking insects [4], that multiplies in the xylem [5], causing occlusion of xylem vessels and water and nutrient stress. It has been considered a quarantine pest, for affecting economically important agricultural crops [6].…”

Predictive studies are essential to establish fundamental data for monitoring and controlling Xylella fastidiosa infections in our country. Limited knowledge exists about how Xylella fastidiosa interacts with the plant host's immune system, leaving numerous unanswered questions regarding Xylella fastidiosa biology and its interactions with national plant hosts. Key inquiries include understanding of how the plant immune system interfaces with Xylella fastidiosa in the xylem and identifying the specific or shared mechanisms underlying the susceptibility of different hosts. Factors such as the presence of insect vectors, abundance of host plants, and climate suitability play pivotal roles in Xylella fastidiosa dispersal. We recommend that countries identified with relatively high risk, like Portugal, undertake thorough individual risk analyses. The implementation of preventive measures and, if necessary, the enhancement of surveillance systems for early detection of Xylella fastidiosa in plants and insect vectors are crucial steps. Additionally, raising awareness is of equal importance to mitigate socioeconomic and ecological impacts on their ecosystems.

“…Sweep nets are the most widely applied sampling method of P. spumarius adults [ 11 , 17 , 18 , 19 , 20 , 21 ] but, as reported by Purcell et al [ 22 ], although this method is highly effective for the evaluation of insects on ground cover, it is less effective on canopies. Attempts to use vacuum samplers, such as the backpack motor D-Vac, have provided poor results in the collecting of vectors of X. fastidiosa in vineyards, and on almond and olive trees [ 23 ].…”

Following the detection of the quarantine bacterium Xylella fastidiosa (Wells et al.) in the Apulia region (southern Italy) and the identification of spittlebugs as the main vector species that contributes to its epidemic spread, monitoring activities have been intensified in an attempt to implement vector control strategies. To date, sweep nets have been the most widely used sampling method to monitor adult spittlebug populations. Field experiments were carried out, during 2018 and 2019, to evaluate the effectiveness of sticky traps in capturing spittlebugs in different woody crops. The attractiveness of different traps was compared: four colored sticky traps (white, red, blue, and yellow), with the yellow sticky traps having three different background patterns (plain yellow, yellow with a black circle pattern, and yellow with a black line pattern). In addition, the efficiency of the yellow sticky traps was evaluated by placing the traps on the ground or hanging them from the canopies in orchards with different spittlebug population densities. Trap catches of Philaenus spumarius (Linnaeus) and Neophilaenus campestris (Fallén) (Hemiptera: Aphrophoridae) were compared with those collected using sweep nets. The two spittlebug species showed a similar response to the colored traps and were mainly attracted to the yellow sticky traps. Captures throughout the adult season indicated that an accurate estimation of the presence and abundance of spittlebugs can be obtained by integrating the two sampling methods. Moreover, sweep nets appeared to be more efficient in collecting adults soon after their emergence, while the use of sticky traps was more efficient in the rest of the adult season when the use of traps can significantly expedite vector monitoring programs.

“…Future projections indicate, in a worst-case scenario, an economic impact of 5.2 billion Euros in Italy alone for the next 50 years [9]. Hence, X. fastidiosa was declared a quarantine pest by the European Commission, and was the highest-ranked crop infesting pest according to the Impact Indicator for Priority Pests (I2P2) metric, leading all the economic, social, and environmental ranked domains in 2019 [10].…”

Xylella fastidiosa is a gram-negative phytopathogenic bacterium that caused a significant economic impact around the world. In the last decade, genome-scale metabolic models have become important systems biology tools for studying the metabolic behaviour of different pathogens and driving the discovery of novel drug targets. In this work, a GSM model of X. fastidiosa subsp. pauca De Donno was developed. The model comprises 1164 reactions, 1379 metabolites, and 508 genes. in silico validation of the metabolic model was achieved through the comparison of simulations with available experimental data. Aerobic metabolism was simulated properly and fastidian gum production rates predicted accurately. The GSM model allowed identifying potential drug targets, using a pipeline based on the model's gene essentially analysis.
