Seasonal and daily patterns in the flight activity of Trioza erytreae (Del Guer...
Rodrigues, Isabel; Félix‐Oliveira, Diogo; Otero, Rosa Pérez; Pereira, José Alberto; Fereres, AlbertoThe psyllid Trioza erytreae (del Guercio, 1918) (Hemiptera: Triozidae) is one of the vectors of Candidatus liberibacter spp., the causal agent of the huanglongbing (HLB) the main citrus disease worldwide. In this study, we investigated for the first time how the flight behavior of T. erytreae is influenced by factors such as sex or daily and seasonal pattern fluctuations by using a flight mill device under cont...
Assessment of Trioza erytreae microbiome and mitochondrial genome variability b...
Chiumenti, Michela; Nicoloso, Vittorio; Fereres, Alberto; Pereira, José Alberto; Maree, Hans J.; Bester, Rachelle; Reynaud, Bernard; Delatte, HélèneHuanglongbing, a devastating citrus disease, is associated with 'Candidatus Liberibacter asiaticus', 'Ca. L. africanus' or 'Ca L. americanus', bacteria transmitted by the psylloids Diaphorina citri and Trioza erytreae. Using a DNA-Seq and metabarcode sequencing integrated approach, the first catalogue of endosymbionts associated with T. erytreae from the Iberian Peninsula, South Africa and African Islands, was ...
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...
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 ...
Climate tolerances of Philaenus spumarius should be considered in risk assessme...
Godefroid, Martin; Morente, Marina; Schartel, Tyler E.; Cornara, Daniele; Purcell, Alexander H.; Gallego Cambronero, Diego; Moreno, AránzazuThe bacterium Xylella fastidiosa (Xf) is an invasive insect-borne pathogen, which causes lethal diseases to important crops including olives, citrus, almonds and grapes as well as numerous forest, ornamental, and uncultivated plants. Outbreaks of Xf-related plant diseases are currently occurring in the Mediterranean region, causing substantial losses to various agricultural sectors. Several models have recently...
Potential areas of spread of Trioza erytreae over mainland Portugal and Spain
Benhadi-Marín, Jacinto; Fereres, Alberto; Pereira, J.A.Trioza erytreae is one natural psyllid vector of Candidatus liberibacter, the causal agent of the citrus greening disease (HLB). Since its introduction in 2014 into the Iberian Peninsula, T. erytreae was able to spread continuously toward southern coastal regions of Portugal and northern coastal regions of the Cantabric sea in Spain. Identifying key areas of potential colonization by the psyllid vector is cruci...
Sampling and distribution pattern of Trioza erytreae Del Guercio, 1918 (Hemipte...
Benhadi-Marín, Jacinto; Pereira, Luís Fernando; Rodrigues, Isabel; Fereres, Alberto; Pereira, J.A.Developing efficient sampling protocols is essential to monitor crop pests. One vector of the citrus disease HLB, the African citrus psyllid Trioza erytreae Del Guercio, 1918 (Hemiptera: Triozidae), currently threatens the lemon industry throughout the Mediterranean region. In this work, a pool of sampling methods devoted to monitoring the population of T. erytreae was compared, its spatial distribution in the ...
Host plant preference of Trioza erytreae on lemon and bitter orange plants
Benhadi-Marín, Jacinto; Garzo, Elisa; Moreno, Aránzazu; Pereira, J.A.; Fereres, AlbertoTrioza erytreae, the African citrus psyllid, is a vector of Candidatus Liberibacter spp., the causal agent of the citrus greening disease or Huanglongbing (HLB). The spread of the vector throughout the Iberian Peninsula has been continuous since its introduction in mainland Spain in 2014. The patterns of host preference and feeding behaviour largely depend on olfactory cues. Understanding these patterns is cruc...
Populations and host/non-host plants of Spittlebugs Nymphs in olive orchards fr...
Villa, Maria; Rodrigues, Isabel; Baptista, Paula; Fereres, Alberto; Pereira, J.A.The Aphrophoridae family contains important vectors of Xylella fastidiosa, a serious bacterial plant disease. In olive orchards, nymphs usually feed on the ground-cover vegetation. However, detailed information about their populations and host/non-host plants in some regions threatened by Xylella, such as the northeast of Portugal, is very limited. The goal of our work was to identify the vector species, nympha...
A model to predict the expansion of trioza erytreae throughout the iberian peni...
Benhadi-Marín, Jacinto; Fereres, Alberto; Pereira, J.A.Assessing the potential of spread of an introduced crop pest in a new country is crucial to anticipating its effects on crop production and deriving phytosanitary management toward reducing potential negative effects. Citrus production represents a key agricultural activity throughout the Mediterranean basin. The African citrus psyllid Trioza erytreae (del Guercio, 1918) (Hemiptera: Triozidae) is a natural vect...
