Impact on the flow of ecosystem services The EKE shows major impacts of the invasion of Xf subsp. pauca on the delivery of ES in Puglia (Supplementary Material C, Table S.C1). One of the experts indicated that “a simple aerial picture of the landscape from the infected zone in Salento (e.g. Fig. 3, Fig. 4) can effectively demonstrate the devastating impacts of the disease on olive cultivation, Mediterranean shrub vegetation, and the associated ecosystem”.

He described the impact as “no more millenarian or centenarian monumental olive trees are alive in the Salento area, with a “global” effect on the entire agroecosystem”. Fig. 3. Fig. 4. The experts noted that the negative impacts on ES provisioning (and biodiversity) are mainly due to the disease, rather than due to the control measures such as chemical pesticides, weeding and pruning. 3.1.1.

INSECTS 07/09/20 Biology and Prevalence in Northern Italy of Verrallia aucta (Diptera, Pipunculidae), a Parasitoid of Philaenus spumarius (Hemiptera, Aphrophoridae), the Main Vector of Xylella fastidiosa in Europe

(Hemiptera Aphrophoridae), the main vector of Xylella fastidiosa Wells et al. in Europe, has few known natural enemies. The endoparasitoid Verrallia aucta (Fallén) (Diptera, Pipunculidae) was first noticed a long time ago but very little is known about its biology and prevalence. In this study, the presence and prevalence of V. aucta were investigated in different regions of northern Italy, both in plain–foothill and montane zones. Parasitic larvae were identified by the dissection of spittlebug adults, P. spumarius and Neophilaenus campestris (Fallén), and by a new species-specific molecular tool targeting the ITS2 and COI genomic regions, developed in this work. A small-scale rearing was set up to gain information on the life cycle of V. aucta on its main host P. spumarius. ►▼ Show Figures.

Fausto Venturi, a local farmer who devotes autumn weekends to making olive oil, could not have been happier. The weather was perfect for harvesting the Moraiolo olives. The small, round green fruit is indigenous to Umbria and Tuscany, prized by olive growers for its high yield and among connoisseurs for the oil’s gorgeous emerald-green colour and fruity aroma, with hints of artichokes and herbs. Better yet, the trees were in near full bloom, signalling a rare bumper crop. NATIONALGEOGRAPHIC - AOUT 2018 - Italy's Olive Trees Are Dying. Can They Be Saved?

Bunches of leaves turned brown and crunchy around the edges. Then, whole groves started to wane. Farmers whose families had tended olives for generations watched their trees dry up and their businesses plummet. At first, it wasn’t clear what was causing the decline. OLIVEOILTIMES 19/08/19 Xylella Fastidiosa Could Be Contained With Better Monitoring. A new study by Enrico Bucci from the Sbarro Health Research Organization (SHRO) suggests that the current strategy for monitoring Xylella fastidiosa fails to identify all the infected plants and enables progression of the epidemic via undetected infection hotspots.

The data revealed in Bucci’s report on the effectiveness of current measures could prove vital for the fine-tuning of an effective containment strategy; which due to the lack of a cure for Xylella offers the best chance of stopping the disease in its tracks and preserving both the traditional landscapes of the impacted Mediterranean countries and their economies. Bucci told Olive Oil Times that data shows there is a failure in the current disease monitoring strategy. He believes the weakness can be attributed to the way in which trees are sampled.

Whilst the current focus is on trees displaying symptoms; most newly infected plants are usually symptom-free and therefore escape detection.

A vicious bacterium that is devastating southern Italy’s valuable olive groves is still spreading years after it was identified, because of opposition to measures meant to contain the pathogen.

NATURE 13/11/18 Italy’s olive crisis intensifies as deadly tree disease spreads - Containment measures meant to stop a rampant bacterium have been frequently delayed.

After months of inaction, authorities in the Puglia region have now resumed efforts to track the spread of the bacterium, Xylella fastidiosa, which causes a disease called olive quick decline syndrome (OQDS) that cannot be cured or eradicated. But scientists say that the delays in implementing disease-containment measures have added to the growing risk that the infection will spread out of the Puglian peninsula, the region contained within the heel of Italy’s ‘boot’, and towards olive groves in Italy’s main landmass. Italy declared a state of emergency over the crisis in 2015.

But quarantine efforts — which can involve uprooting beloved, ancient trees — have been opposed by environmentalists and some farmers, and stopped again most recently in May.

Contexte Xylella fastidiosa est l'une des bactéries les plus dangereuses pour les végétaux à l'échelle mondiale: elle cause diverses maladies, invariablement mortelles pour les végétaux infectés, qui ont des répercussions économiques dévastatrices dans le secteur de l'agriculture. Les États membres doivent prendre toutes les mesures nécessaires à l'éradication de Xylella fastidiosa et, lorsque ce n'est pas possible, empêcher sa propagation sur le reste du territoire italien et de l'Union dans son ensemble. À plusieurs reprises, la Commission a instamment demandé à l'Italie de s'acquitter de ses obligations. Sci Rep. 2017 Dec 18;7(1): Isolation and pathogenicity of Xylella fastidiosa associated to the olive quick decline syndrome in southern Italy.

Detection and culture of X. fastidiosa from symptomatic olive trees X. fastidiosa was detected by qPCR in all fifty-eight symptomatic trees sampled in the oldest (2013) and the more recent (2016) OQDS outbreaks.

Sci Rep. 2017 Dec 18;7(1): Isolation and pathogenicity of Xylella fastidiosa associated to the olive quick decline syndrome in southern Italy.

Quantitative PCR reactions yielded quantitative cycles (Cq) in the range of 21–26, which corresponded to an average population of 4.5–6 (log cells/gr of tissue when interpolated on the linear standard curve generated using 10-fold serial dilutions of a bacterial suspension with known concentration). Fluorescence signal in the negative and non-template controls remained below the background, with no Cq values. Actively growing X. fastidiosa colonies were successfully obtained from 51 of the 58 olive samples, collected in distinct OQDS foci (Table 1). Colonies grew relatively slowly, requiring 7 to 15 days to become visible (Fig. 1) and developed in several spotted imprints of each sample, an indication of the wide distribution of the bacterium in symptomatic trees.

NATURE 07/06/17 Italy rebuked for failure to prevent olive-tree tragedy - European Commission reveals widespread delays by the country’s authorities to halt spread of deadly plant disease.

A vicious pathogen that is destroying historic olive groves in Puglia, southern Italy, is marching north and threatens to reach the rest of Europe. Yet Italian authorities last year failed to track the infection’s spread, and didn’t follow containment plans agreed with the European Commission, according to an audit released last week by the commission. Scientists in the region aren’t surprised by the criticism: their efforts to stop the infection have been repeatedly hampered over the past four years, since they first suspected that the disease was caused by the bacterium Xylella fastidiosa. “The situation is ridiculous,” says plant pathologist Giovanni Martelli at the University of Bari in northern Puglia. The pathogen — for which there is no cure — had never been seen in Europe before it was spotted in Puglia in 2013.

LEGGE REGIONALE 29 marzo 2017, n. 4 “Gestione della batteriosi da Xylella fastidiosa nel territorio della regione Puglia” Biological Invasions 21/02/17 Modelling the spread and control of Xylella fastidiosa in the early stages of invasion in Apulia, Italy. The rapid invasion of X. fastidiosa causing OQDS in Italy is causing substantial damage to olive production and the local economy, and is extremely worrying for neighbouring olive-producing regions in Italy and in other Mediterranean regions (Bosso et al. 2016a, b).

Predicting its spread is important, since this will help guide control strategies and assess risk, and existing statistical distribution models (Bosso et al. 2016a, b) only predict the potential spatial extent of the disease, not the rate and patterns of spread or impacts of spatial control approaches. Here, we have developed a simple model based on previous work (Chapman et al. 2015) which we have compared to the known spatial and temporal dynamics of X. fastidiosa and shown that the model qualitatively reproduces the pattern and speed of spread of X. fastidiosa in the Apulian region. Given the paucity of data, our model has provided useful insight into the spread of X. fastidiosa and potential control strategies.

JOURNAL OF PEST SCIENCE 12/07/16 Spittlebugs as vectors of Xylella fastidiosa in olive orchards in Italy. The introduction of X. fastidiosa into Italy, and its primary role in olive desiccation and dieback as clearly shown by Saponari et al. (2016), has highlighted important knowledge gaps for the development of management practices aimed at reducing the spread of this pathogen in Europe. Among these is the limited information available on spittlebugs as X. fastidiosa vectors. In this study, we attempted to address questions of immediate importance, such as which potential vector species are present in olive orchards in southern Apulia. P. spumarius transmitted X. fastidiosa from olive to olive plants as well as from a range of infected-source plant species to periwinkle test plants. Furthermore, the spittlebug P. spumarius was the most abundant species found in orchards on both weeds and olive trees; X. fastidiosa prevalence in P. spumarius on olive trees was approximately twice that of insects collected from weeds, but the prevalence was very high in both environments.

Paris, 3 avr 2015 (AFP) - Le ministre de l'Agriculture Stéphane Le Foll a décidé d'interdire l'importation en France de végétaux sensibles à une bactérie tueuse qui s'attaque notamment aux oliviers et a déjà fait des ravages en Italie. « Actuellement, aucun foyer n'a été détecté en France », a déclaré le ministère vendredi dans un communiqué. Mais pour éviter que la maladie ne s'étende en France, « un arrêté a été signé ce jour et sera publié demain afin d'interdire l'importation en France de végétaux sensibles à Xyllela fastidiosa et provenant de zones touchées par la bactérie », indique le texte.

Cette interdiction concerne les échanges intra-européens depuis la région des Pouilles en Italie, et les importations issues des zones infectées des pays tiers concernés, notamment le continent américain. Elle sera assortie du renforcement du plan de contrôle et de surveillance sur l'ensemble du territoire national.

The recommendation follows an assistance request from the European Commission after the disease was found on olive trees in Apulia in the Lecce province. While noting that no successful eradication of the disease has ever been achieved once it has been established outdoors, the EFSA emphasized a focus was needed on two main pathways in containment areas – plants for planting and infective insects in plant consignments.
