Melanaspis corticosa: a new insect pest of olive trees in Europe
Mazzeo, Gaetana; Pellizzari, Giuseppina; Mateus, Célia; Silva, Elsa Borges da; Russo, Agatino; Nucifora, Salvatore; Soares, Celestino; Tomé, DoraThe presence of the South African Obscure Scale, Melanaspis corticosa (Brain) (Hemiptera, Diaspididae), was detected infesting olive trees, in Portugal. The identity of the scale insect was confirmed based on both morphological and molecular studies. Until now, this species was only known in a few African countries, including Guinea, Mozambique, South Africa and Zimbabwe. This is the first record of this specie...
Drosophila suzukii: conhecer para melhor combater
Mateus, Célia; Godinho, Maria do Céu; Figueiredo, ElisabeteDrosophila suzukii (Matsumura) ou “drosófila-da-asa-manchada” é uma espécie que dispensa apresentações, devido aos prejuízos que tem vindo a causar em várias culturas, principalmente nas de pequenos frutos. Tal como aconteceu em 2016, no último Colóquio Nacional de Produção de Pequenos Frutos, faz-se aqui uma atualização do conhecimento sobre esta espécie, através da análise de trabalhos de investigação realiza...

Seabra, Sofia G.; Martins, Joana; Brás, Patrícia; Tavares, Ana M.; Freitas, Inês; Barata, António; Rebelo, Maria Teresa; Mateus, CéliaThe tiger-fl y Coenosia attenuata Stein (Diptera: Muscidae: Coenosiini) is a generalist predator that preys on several pests of greenhouse crops and is considered a biological control agent in the Mediterranean region. Previous behavioural observations identifi ed its preferred prey, but a more in-depth evaluation will benefi t from using Polymerase Chain Reaction amplifi cation of prey DNA remains in the gut o...

Seabra, Sofia; Neto, Carina; Rodrigues, Ana Sofia; Streito, Jean-Claude; Genson, Guénaëlle; Pierre, Eric; Silva, Sara; Popova, Gana; Marabuto, EduardoPhilaenus spumarius, is a widespread and polyphagous xylem-feeding insect. It is also the main vector of Xylella fastidiosa in Europe (Saponari et al., 2014). P. spumarius and P. tesselatus are considered sister species, differentiated at the male genitalia level but not at karyological, mitochondrial DNA and some nuclear genes levels (Maryanska-Nadachowska et al., 2012; Rodrigues et al., 2014). Genome-wide mar...
Methodological approach to assess biodiversity in agro ecosystems – A case study
Tavares, Catarina; Gouveia, Ana F.; Crespo, Luís; Mateus, Célia; Rebelo, M. TeresaIn agroecosystems, the evaluation of biodiversity is extremely important given its relation with their sustainability, however it is a difficult and expensive task. The use of the higher taxa surrogacy has been proposed as an effective and less expensive way to assess biodiversity, but is still being used mainly in natural, more stable, ecosystems. In this study, we tested the use of the higher taxa surrogacy a...
An overview of Vicia faba role in ecosystems sustainability and perspectives fo...
Veloso, Maria Manuela; Mateus, Célia; Suso, Maria JoséFaba bean (Vicia faba L.) that is grown world-wide as a protein source for food and feed also offers ecosystem services such as N2 fixation and enhancement of wild fauna diversity such as bee-pollinators and other beneficial organisms. Thus, it helps to mitigate the pollinator decline and it is recognized that also contributes to pest control not only in the crop itself but also in the neighbouring/associated c...
Monitorização dos insetos potenciais vectores de Xylella fastidiosa na Herdade ...
Sargento, Liliana; Boavida, Conceição; Mateus, Célia; Patanita, Maria IsabelXylella fastidiosa é uma bactéria de quarentena restrita ao fluido xilémico de uma vasta gama de hospedeiros vegetais, alguns dos quais constituindo culturas agrícolas e florestais de grande importância económica para Portugal. A bactéria é transportada e transmitida por insetos picadores-sugadores de fluido xilémico, nomeadamente Hemiptera Auchenorrhyncha (Cicadomorpha). Em Itália, Philaenus spumarius (Hemipte...
