Azorean Cryptomeria japonica immature female cones essential oil: Effect of hyd...
Arruda, Filipe; Lima, Ana; Janeiro, Alexandre; Rodrigues, Tânia; Baptista, José; Rosa, José S.; Machado, Alexandra; Figueiredo, Ana C.; Lima, ElisabeteABSTRACT: Cryptomeria japonica’s wood production in Azores generates large amounts of underutilized biomass residues, such as immature female cones (Az–CJIFC), that can be used to produce essential oils (EOs). Hydrodistillation (HD) can be used both to obtain and to fractionate EOs. In this study, EOs from Az–CJIFC, grinded (GR) and non grinded (NGr) fresh samples, were obtained via HD over 4 h, yielding 1.0 % ...

Arruda, Filipe; Lima, Ana; Janeiro, Alexandre; Rodrigues, Tânia; Baptista, José; Rosa, José S.; Machado, Alexandra; Figueiredo, Ana CristinaCryptomeria japonica's wood production in Azores generates large amounts of underutilized biomass residues, such as immature female cones (Az–CJIFC), that can be used to produce essential oils (EOs). Hydrodistillation (HD) can be used both to obtain and to fractionate EOs. In this study, EOs from Az–CJIFC, grinded (GR) and non-grinded (NGr) fresh samples, were obtained via HD over 4 h, yielding 1.0 % and 0.5 %,...
Macaronesian Plants as Promising Biopesticides against the Crop Pest Ceratitis ...
R. Tavares, Wilson; Jiménez, Ignacio A.; Oliveira, Luísa; Kuhtinskaja, Maria; Vaher, Merike; Rosa, José S.; Seca, A. M. L.; Bazzocchi, Isabel L.ABSTRACT: Ceratitis capitata is responsible for significant economic losses in the fruit production industry, and the market lacks biopesticides that are effective but also cheaper and less contaminating, with fewer negative impacts on the environment. In this regard, the present study suggests as potential options ethanolic extracts from several Macaronesian plants, which inhibit the oviposition and are toxic ...
Cryptomeria japonica : inovar para (re)criar valor
Arruda, Filipe Martim Pacheco; Lima, Ana; Pavão, Alexandre; Baptista, José; Rosa, José S.; Lima, Elisabete[…] Por que as florestas são importantes? Os factos falam por si: as florestas cobrem 30% da superfície terrestre; armazenam cerca de 300 gigatoneladas de carbono na biomassa; são o habitat de mais de 80% de todas as espécies terrestres; são o meio de subsistência para cerca de 1,6 biliões de pessoas; contribuem para a saúde humana e bem estar, fatores fundamentais para a qualidade de vida de um indivíduo; ofer...
Molluscicidal activity of four Apiaceae essential oils against the freshwater s...
Sousa, Rose Marie O. F.; Rosa, José S.; Cunha, Ana; Ferreira, Manuel FernandesSnails of the family Lymnaeidae are an essential link in the transmission of zoonotic diseases. Radix peregra is a European freshwater snail and a susceptible intermediate host of Fasciola hepatica, the causing agent of fascioliasis. Essential oils (EOs) extracted from Anethum graveolens (dill), Cuminum cyminum (cumin), Foeniculum vulgare var. vulgare (bitter fennel) and Petroselinum crispum (plain leaf parsley...
Chemical composition and biological activities of Laurus essential oils from di...
Furtado, R.; Baptista, José; Lima, Elisabete; Paiva, Lisete S.; Barroso, J. G.; Rosa, José S.; Oliveira, LuísaEssential oils (EO) and eight pure components from the fresh leaves of Laurus novocanariensis (LN) from Madeira and of Laurus azorica (LA) from four Azorean Islands (S. Miguel-SMI, S. Maria-SMA, Pico-PIC and S. Jorge-SJO) were evaluated for fumigant and contact insecticidal effects on adult stage of Mediterranean fruit fly (medfly) and for inhibition of oviposition. The chemical composition of EO were analysed ...
Cytotoxic, antibacterial, antioxidant, and anticholinesterasic activity of Juni...
Oliveira, Nemésia; Medeiros, Sofia; Barreto, Maria do Carmo; Seca, Ana M. L.; Rosa, José S.The cytotoxic, antibacterial, antioxidant and anticholinesterasic (anti-AChE) activities of the methanol and acetone extracts of Juniperus brevifolia wood and bark were determined. The present study demonstrates that bark extracts of J. brevifolia are the most active and showed good antioxidant activity, lower anti-AChE activity except for the acetone extract, poor cytotoxic and antibacterial activities and abs...
Assessment of molluscicidal activity of essential oils from five Azorean plants...
Teixeira, Tânia; Rosa, José S.; Rainha, Nuno; Baptista, José A. B.; Rodrigues, ArmindoThe molluscicidal activity of essential oils from two endemic (Juniperus brevifolia; Laurus azorica) and three introduced (Hedychium gardnerianum; Pittosporum undulatum; Psidium cattleianum) Azorean plants against the snail Radix peregra was studied under laboratory conditions. Essential oils from leaves of H. gardnerianum, L. azorica and J. brevifolia presented promising molluscicidal activity on both adults a...
Pesquisa de agentes entomopatogénicos na ilha do Pico (Açores)
Rosa, José S.Durante a “Expedição Científica Pico 2005” efectuou-se a recolha de amostras de solo para pesquisar nemátodes entomopatogénicos. Com o designado “Galleria trap method” e pela técnica de flutuação-centrifugação re-isolou-se um nemátode do género Steinernema. Esse nemátode, Steinernema carpocapse, isolado Az27 foi pela primeira vez isolado na ilha do Pico no ano de 1991.; ABSTRACT: A survey for entomopathogens in...
Susceptibility of Pseudaletia unipuncta (Lepidoptera; Noctuidae) to Entomopatho...
Medeiros, Jorge R.; Rosa, José S.; Tavares, João; Simões, NelsonThe armyworm, Pseudaletia unipuncta (Haworth), is a serious pest to the Azores's pastures. In laboratory bioassays we tested the susceptibility of this insect to entomopathogenic nematodes isolated in Azores: Steinernema carpocapsae Az20, Az150, and A48 strains, S. glaseri Az26 strain and Heterohabditis bacteriophora Az33 strain. The A48, Az20, and Az150 strains caused parasitism rates of 96.6, 90, and 53.3%, a...
