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...
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...
The visitor to Vinhais Biological Park
Rodrigues, Isabel; Esteves, Elsa Tavares; Martins, Márcio RibeiroNatural spaces have become a tourist attraction that allows leisure activities to be practiced, contributing to the tourist experience and a better quality of life for the communities visited and visitors. Environmental preservation, fauna, flora and the various ecosystems associated with natural spaces have given rise to ecotourism as a segment of tourism. The Vinhais Biological Park, part of the Montesinho Na...
Ground-cover vegetation composition shapes the abundance of Sphaerophoria scrip...
Madureira, Marta; Rodrigues, Isabel; Pereira, J.A.The ground-cover vegetation, commonly found in olive groves, provides shelter and vital floral resources for syrphids. Such resources can contribute to syrphids’ growth, development, reproduction, and survival, allowing them to maximize their function as natural pest enemies, pollinators, and decomposers of organic matter. Therefore, identifying the flowering plant families driving the abundance of Sphaerophori...
Spatial distribution pattern of male adults of Phyllocnistis citrella Stainton ...
Costa, Jaciley Bragança; Madureira, Marta; Pereira, J.A.; Rodrigues, IsabelPhyllocnistis citrella Stainton, commonly known as the citrus leafminer, threatens global citrus production. This study focuses on elucidating the population dynamics and spatial distribution of P. citrella in lemon orchards located in Northern Portugal. From May to December, using delta traps with sexual pheromones, the levels of the adult population were monitored, and aggregation indices were calculated. Fiv...
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...
Cicadomorpha community (Hemiptera: Auchenorrhyncha) in different agroecosystems...
Rodrigues, Isabel; Baptista, Paula; Pereira, J.A.1. The infraorder Cicadomorpha is a diverse group comprising several species considered important pests of economic crops and species that may act as vectors of plant pathogens. In Europe, the gram-negative bacterium Xylella fastidiosa is one of the most important and severe insect-borne plant pathogens associated with the infraorder Cicadomorpha. 2. Therefore, the knowledge of the abundance and diversity of na...
Intermediate fragmentation surrounding vineyards favours the Coleoptera communi...
Taranto, Luisa; Rodrigues, Isabel; Santos, Sónia Marina Figueiredo Abrantes; Villa, Maria; Pereira, J.A.Insects of the order Coleoptera play an essential role in agricultural sustainability by supporting many ecosystem services (such as biological control, nutrient cycling or pollination). In agroecosystems, the Coleoptera community may be influenced by the surrounding landscape, which can provide living resources, like food or shelter, during different seasons, originating spillover movements between different e...
The surrounding landscape shapes the abundance of Sphaerophoria scripta and Mel...
Madureira, Marta; Rodrigues, Isabel; Villa, Maria; Pereira, J.A.1. The intensification of urban and agricultural use in the landscape is the major driver of biodiversity loss and the consequent decrease of ecosystem services provided by insects. Syrphids are important ecosystem service providers, including pest regulation, pollination, and matter decomposition. 2. Understanding how the surrounding landscape to crops affects syrphids is essential to implementing strategies t...
Cicadomorpha community (hemiptera: auchenorrhyncha) in portuguese vineyards wit...
Rodrigues, Isabel; Rebelo, Maria Teresa; Baptista, Paula; Pereira, J.A.Simple Summary Cicadomorpha (Hemiptera: Auchenorrhyncha) represent a group of concern in vineyards since they can cause damage directly through feeding or can be vectors for serious pathogens such as grapevine yellows or the bacterium Xylella fastidiosa, the causal agent of Pierce's disease. Therefore, knowing the diversity and abundance of these insects in Portuguese vineyards is the first step for implementin...
