Polyphasic approach to the selection of Esteya isolates for the control of the ...
Pires, David; Vicente, Cláudia S. L.; Mota, Manuel; Inácio, Maria L.Pine wilt disease, caused by the pinewood nematode, Bursaphelenchus xylophilus, is a major phytosanitary concern to pine forests worldwide. Managing pine wilt disease involves a complex logistical undertaking, with limited effectiveness and significant ecological repercussions. An increasing demand for biosolutions has sparked an interest in microbial antagonists capable of controlling the nematode. Esteya spp....
Infection of In Vivo and In Vitro Pines with the Pinewood Nematode Bursaphelenc...
Faria, Jorge M. S.; Figueiredo, Ana Cristina S.; Teixeira, Dora M.; Inácio, Maria L.The pinewood nematode (PWN) is a phytoparasite that causes pine wilt disease (PWD) in conifer species. This plant parasitic nematode has heavily contributed to pine deforestation in Asian countries, e.g., Japan, China, and Korea. Over the last two decades, in Europe, Portugal and Spain have been greatly affected. Research on the mechanisms of PWN infection and/or PWD progression in susceptible host species reli...
Co-culturas planta-nemátode para a despistagem de nematicidas sustentáveis cont...
Faria, Jorge M. S.; Vicente, Cláudia S. L.; Rusinque, Leidy; Camacho, M. João; Inácio, Maria L.As doenças causadas pelos nemátodes fitoparasitas permanecem uma considerável limitação á produção agrícola global. Um crescente número substâncias activas, utilizadas em formulações nematicidas comerciais, têm sido proibidas por políticas comuns de gestão de pragas, devido a preocupações ambientais e de saúde humana. Muitas vezes, os pesticidas de substituição demonstram uma menor eficiência no campo, o que se...
Root-knot nematode assessment: species identification, distribution, and new ho...
Rusinque, Leidy; Camacho, Maria João; Serra, Clara; Nóbrega, Filomena; Inácio, Maria L.Considered one of the most devastating plant parasitic nematodes worldwide, Meloidogyne spp. (commonly known as the root-knot nematodes (RKNs)) are obligate sedentary endoparasites that establish in the roots, causing hyperplasia and hypertrophy of surrounding cells, triggering the formation of galls. These galls will affect root development and physiology, leading to substantial yield losses. During 2017-2022,...
Essential Oil Volatiles as Sustainable Antagonists for the Root-Knot Nematode M...
Faria, Jorge M. S.; Rusinque, Leidy; Cavaco, Tomás; Nunes, João C.; Inácio, Maria L.Climate change is prompting a shift of tropical pests to locations with a previously lower probability of invasion. This is the case for root-knot nematodes, Meloidogyne sp., particularly of the tropical group. Among them, M. ethiopica is now considered a threat to European food security. The development of novel sustainable nematicides can be based on in vitro bioassays of highly active phytochemicals, e.g., v...
Linking nematode communities and soil health under climate change
Pires, David; Orlando, Valeria; Collett, Raymond L.; Moreira, David; Costa, Sofia R.; Inácio, Maria L.Soil health is intimately intertwined with ecosystem services. Climate change negatively impacts ecosystem functioning, by altering carbon and nitrogen biogeochemical cycles and shifting nutrient bioavailability, thus hampering food production and exacerbating biodiversity loss. Soil ecosystem services are provided by belowground biota, and as the most abundant metazoans on Earth, nematodes are key elements of ...
Synergistic Activity of Cymbopogon citratus and Mentha piperita Essential Oils ...
Gonçalves, Diogo; Cavaco, Tomás; Pombo, Ana; Moiteiro, Cristina; Teixeira, Dora Martins; Inácio, Maria L.; Faria, Jorge M.S.The pinewood nematode (PWN) Bursaphelenchus xylophilus is a major threat to pine forests. Research on sustainable pest management strategies is now a priority. Essential oils (EOs) are biodegradable, complex mixtures of volatiles that can show low toxicity to mammals and powerful nematicidal activities depending on their chemical composition. In the present work, the EOs of four plants were screened against the...

Six First Reports of Pin Nematodes from Portugal, with an Update of the Systema...
Rosmaninho, Teresa; Mota, Manuel; Inácio, Maria L.; Eisenback, Jonathan D.; Gutiérrez-Gutiérrez, CarlosPin nematodes (Paratylenchus spp.) currently comprise 132 species of polyphagous plant ectoparasites with at least seven species that are plant pathogenic emphasizing the need for correct identification to establish an appropriate management strategy. Sequences of highly conserved regions of ribosomal and mitochondrial RNA genes are a powerful species-level diagnostic tool within Tylenchulidae. A nematological ...
First report on the synergistic interaction between essential oils against the ...
Faria, Jorge M. S.; Cavaco, Tomás; Gonçalves, Diogo; Barbosa, Pedro; Teixeira, Dora Martins; Moiteiro, Cristina; Inácio, Maria L.Control of the pinewood nematode (PWN), the causal agent of pine wilt disease, can be achieved through the trunk injection of nematicides; however, many pesticides have been linked to environmental and human health concerns. Essential oils (EOs) are suitable alternatives due to their biodegradability and low toxicity to mammals. These complex mixtures of plant volatiles often display multiple biological activit...
