Effects of Climatic, Chemical, and Cultural Control Strategies on Community Com...
Nascimento, Patrícia Monteiro; Neto, Ana Carina; Guerreiro, Vera; Barateiro, Anabela; Anjos, Hugo; Coutinho, José Pereira; Antunes, MaríliaA three-year study in two Mediterranean peach orchards monitored Auchenorrhyncha species, including the main vectors of plant pathogens causing significant economic losses. The research focused on the management of two polyphagous leafhoppers, Asymmetrasca decedens and Hebata (Signatasca) solani. Yellow sticky traps were used to track species dynamics and assess population trends in relation to meteorological f...
Challenges of Providing Safe Drinking Water in African Rural Communities: A Cas...
Silveira, Pedro; Rebelo, Maria Teresa; Salvador, DanielAccess to safe drinking water is a fundamental human right, yet it remains a global challenge affecting nearly 2 billion people, particularly in Africa in regions such as Guinea-Bissau. This study investigated the microbiological and physicochemical quality of drinking water in four rural areas of the Oio region of Guinea-Bissau—Cangha N’Tchugal, Cajaque, Infaidi and Insanha—over a one-year period (October 2022...
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...
Strategies for Monitoring Microbial Life in Beach Sand for Protection of Public...
Brandão, João; Valério, Elisabete; Weiskerger, Chelsea; Veríssimo, Cristina; Sarioglou, Konstantina; Novak Babič, Monika; Solo-Gabriele, Helena M.The 2021 revised guidelines of the World Health Organization recommend monitoring the quality of sand in addition to water at recreational beaches. This review provides background information about the types of beaches, the characteristics of sand, and the microbiological parameters that should be measured. Analytical approaches are described for quantifying fungi and fecal indicator bacteria from beach sand. T...
APOB Variants Spectrum and Functional Characterization in Portuguese Patients w...
Ferreira, Maria Rafael Simões do Carmo; Alves, Ana Catarina; Rebelo, Maria TeresaFamilial hypercholesterolaemia (FH) is an autosomal semi dominant disorder of lipid metabolism clinically characterized by increased levels of circulating LDL cholesterol and associated with elevated cardiovascular risk. The genetic diagnosis is usually based on the analysis of LDLR, APOB, and PCSK9 genes. APOB variants are responsible for 5-10% of FH cases, and the variant spectrum of APOB has increased due to...
The potential role of scavenging flies as mechanical vectors of Lagovirus europ...
Lopes, Ana M.; Almeida, Tereza; Diz, Sílvia; Côrte-Real, João V.; Osório, Hugo; Ramilo, David W.; Rebelo, Maria Teresa; Pereira da Fonseca, IsabelThe European rabbit (Oryctolagus cuniculus) populations of the Iberian Peninsula have been severely affected by the emergence of the rabbit haemorrhagic disease virus (RHDV) Lagovirus europaeus/GI.2 (RHDV2/b). Bushflies and blowflies (Muscidae and Calliphoridae families, respectively) are important RHDV vectors in Oceania, but their epidemiological role is unknown in the native range of the European rabbit. In ...
No trilho da investigação em parasitologia
Ramilo, David W.; Rebelo, Maria Teresa; Cardoso, Luís; Fonseca, Isabel Pereira daO primeiro autor deste resumo iniciou o seu doutoramento em 2012, tendo como tema os estudos morfológicos e genéticos em insetos Culicoides, assim como o efeito de moléculas inseticidas em órgãos sensoriais dos mesmos. Após a conclusão do doutoramento em 2016, os estudos na área de Culicoides continuaram durante o seu pós-doutoramento (2017-2020). Adicionalmente, outros trabalhos de investigação foram conduzido...
The bee fauna (Hymenoptera: Apoidea: Anthophila) of allotments in downtown Lisbon
Azevedo, Miguel; Figueiredo, Elisabete; Rebelo, Maria TeresaIn the last ten years, a growing number of studies have focused on urban green areas as potential refuges for biodiversity, where private gardens, urban parks and green roofs have relatively high diversities of wild bees. However, the western Mediterranean is still poorly studied and is a biodiversity hotspot that is already suffering the consequences of climate change. It is essential to rectify this and under...
Size does matter: intraspecific geometric morphometric analysis of wings of the...
Rodrigues-Filho, Sérgio J.M.; Prado e Castro, Catarina; Lopes, Luís Filipe; da Fonseca, Isabel Pereira; Rebelo, Maria TeresaBlowflies have forensic, sanitary and veterinary importance, as well as being pollinators, parasitoids and ecological bioindicators. There is still little work with real data and from experiments assessing the relationship between blowflies’ morphologic features and environmental and demographic factors. The present work tests whether the variation, in the shape and size, of Chrysomya albiceps (Wiedemann, 1819)...
PrunusFITO - Avaliação do impacto de alguns inimigos (pragas e doenças) nas cul...
Barateiro, Anabela; Ramos, Cristina; Fragoso, Preciosa; Lopes, Sandra; Abrantes, Ana Celisa; Vieira, Francisco José Pereira; Rebelo, Maria TeresaO G.O. PrunusFITO surgiu pela necessidade de conhecer melhor as dinâmicas populacionais de alguns dos inimigos mais relevantes em pessegueiro e cerejeira na Beira Interior, estabelecendo-se como prioritários o cancro, a mosca do mediterrâneo, a cigarrinha verde e ratos em pessegueiros, e a mosca de asa manchada em cerejeira. Relativamente ao cancro foram realizadas observações em plantas sintomáticas de 2018 a ...
