Developing epidemiological preparedness for a plant disease invasion: Modelling...
Ellis, John; Lázaro, Elena; Duarte, Beatriz; Magalhães, Tomás; Duarte, Amílcar; Benhadi-Marín, Jacinto; Pereira, José Alberto; Vicent, AntonioSocietal Impact Statement Huánglóngbìng (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected. By developing a mathematical model of spread in Spain, we tested surveillance and control strategies before any future HLB entry in the EU. We found while some citrus production might be maintained b...
Seasonal olfactory response of Philaenus spumarius (Hemiptera: Aphrophoridae) t...
Rodrigues, Isabel; Benhadi-Marín, Jacinto; Rodrigues, Nuno; Baptista, Paula; Pereira, José AlbertoIn Portugal, the strength of the olive sector relies on the great genetic heritage of traditional olive cultivars. However, this genetic heritage is threatened by the causal agent of olive quick decline syndrome (OQDS), the phytopathogenic bacteria Xylella fastidiosa, reported for the first time in 2019 in the country. This vector-borne pathogen is transmitted by xylem-feeding insects such as Philaenus spumariu...
Does the superfluous killing exhibited by spiders mask the functional response ...
López‐Mercadal, Júlia; Benhadi-Marín, Jacinto; Rodrigues, Isabel; Miranda, Miguel Ángel; Pereira, J.A.The meadow spittlebug Philaenus spumarius L. (Hemiptera: Aphrophoridae) is a xylem-sap feeder and the most abundant and widespread vector of Xylella fastidiosa (Xanthomonadales: Xanthomonadaceae) throughout Europe. Control strategies for the disease are based on containment and eradication measures regulated by the European Union. Within the context of biological control, the use of natural enemies aims at limi...

Paz, Maria Catarina; Barreira, Raquel; Amaro, Luís; Sousa, José Paulo; Benhadi-Marín, Jacinto; Rasko, Mykola; Silva, António Alves da; Alves, JoanaA limitação natural de pragas é um serviço de ecossistema que deve ser promovido nos sistemas agrícolas, já que pode ser usada como alternativa, ou complementarmente, à aplicação de pesticidas. Consiste no consumo das pragas pelos seus inimigos naturais e pode ser promovida através do estabelecimento de componentes paisagísticas que forneçam, a estes inimigos das pragas, alimento alternativo e refúgio, para alé...
Kaolin particle films disrupt landing, settling behavior and feeding of Trioza ...
Félix-Oliveira, Diogo; Benhadi-Marín, Jacinto; Neto, Joana; Sanz, Lorena; Garzo, Elisa; Aguiar, Ana; Fereres, Alberto; Pereira, J.A.BACKGROUND The citrus greening disease or Huanglongbing (HLB) is the most devastating disease of citrus crops. Trioza erytreae is a vector of HLB. Since its introduction in Europe, the insect reached the northern region of Spain and the southern region of Portugal, threatening relevant citrus production areas. Limiting the spread of HLB vectors is mandatory to prevent this disease. In this work, we assessed the...
The assemblage of beetles in the olive grove and surrounding mediterranean shru...
Kubiak, Ketrin; Pereira, J.A.; Tessaro, Dinéia; Santos, Sónia A.P.; Benhadi-Marín, JacintoThe olive tree is perfectly adapted to the Mediterranean region, where it represents high economic, social, and landscape importance, olive orchards being an important repository of biodi- versity. The order Coleoptera encompasses families that provide important ecosystem services, such as pest limitation. The objective of this work was to compare the assemblage of families of Beetles between the olive grove an...
A novel molecular diagnostic method for the gut content analysis of Philaenus DNA
Rodrigues, Isabel; Ramos, Vitor; Benhadi-Marín, Jacinto; Moreno, Aránzazu; Fereres, Alberto; Pereira, J.A.; Baptista, PaulaPhilaenus spumarius is a vector of Xylella fastidiosa, one of the most dangerous plants pathogenic bacteria worldwide. There is currently no control measure against this pathogen. Thus, the development of vector control strategies, like generalist predators, such as spiders, could be essential to limit the spread of this vector-borne pathogen. In this study, a polymerase chain reaction (PCR)-based approach was ...
Web architecture affects the functional response of the space web-builder Kochi...
Félix-Oliveira, Diogo; Pereira, J.A.; Benhadi-Marín, JacintoThe “citrus greening disease” or huanglongbing (HLB) is caused by the Gram-negative bacteria Candidatus Liberibacter spp. One vector of HLB, the African citrus psyllid Trioza erytreae (del Guercio, 1918), was recorded for the first time in 2014, in mainland Spain, and since then, it has spread throughout the Iberian Peninsula. Spiders could be natural enemies of T. erytreae. In this work, we assessed the potent...
Presence and distribution of the African citrus psyllid in São Tomé island
Benhadi-Marín, Jacinto; Félix, Diogo; Carvalho, Miclay dos Reis Pereira; Mendes, José Luis; Baptista, Paula; Pereira, J.A.The African citrus psyllid, Trioza erytreae (Hemiptera: Triozidae), is a natural vector of Candidatus Liberibacter spp., the causal agents of the citrus greening disease or Huanglongbing (HLB). Despite the global losses of the Citrus industry due to HLB, the vector is rapidly spread to new areas threatening citrus crops and raising con-cern for stakeholders. Until now, there was a single old register of T. er y...
Functional diversity of epigeal spiders in the olive grove agroecosystem in nor...
Kubiak, Ketrin; Pereira, J.A.; Tessaro, Dinéia; Santos, Sónia A.P.; Benhadi-Marín, JacintoThe olive grove agroecosystem (Olea europaea L., Oleaceae) is very important in terms of economy and culture throughout the Mediterranean region. In Trás-os- Montes (Portugal), olive groves are commonly surrounded by semi-natural areas consisting of Mediterranean shrublands. Understanding the role of potential predators of olive pests is crucial to enhancing biological control in sustainable agriculture. This s...
