Vê moinhos? São moinhos: Análise dos discursos sobre turbinas eólicas em Alvaiá...
Nunes, Maria João; Delicado, Ana, 1973-; Figueiredo, Elisabete; Horta, AnaEm muitas áreas rurais, os elementos tradicionais que marcam e diferenciam as paisagens convivem hoje com a presença cada vez menos discreta das turbinas eólicas. Encarando a paisagem como uma activação patrimonial, que impacto terão as turbinas eólicas na cultura e identidade local? Tendo por base um estudo de caso em Alvaiázere, onde a instalação do parque eólico levantou polémicas relacionadas, sobretudo, co...
Discursos técnico-científicos sobre energias renováveis em Portugal
Delicado, Ana, 1973-; Truninger, Mónica; Horta, Ana; Figueiredo, Elisabete; Silva, Luís; Fonseca, SusanaAs energias renováveis têm sido apontadas como cruciais não só para a mitigação das alterações climáticas mas também como panaceia para a dependência dos combustíveis fósseis em países que não os produzem, como Portugal. As respostas sociais a estas tecnologias são um fator essencial para a sua difusão e sucesso. Porém, a macro-geração de energias renováveis, designadamente as centrais solares e eólicas, não pr...
Os ácaros na cultura da amora em estufa e infestantes
Pina, Silvia; Ferreira, Maria dos Anjos; Calha, Isabel M.; Figueiredo, ElisabeteAcarological surveys were carried out fortnightly from March to June 2011 on blackberries and weeds in a greenhouse at Fataca Experimental Farm in Odemira, in order to study species diversity and population interaction. This study focused on two blackberry cultivars, ‘Ouachita’ and ‘Karaka Black’. Sixteen mite species were identified on blackberries. The redberry mite Acalitus essigi (Hassan) was the most noxio...
Interação entre as culturas de amora e mirtilo e as adventícias associadas: os ...
Serra, David; Mateus, Célia; Calha, Isabel; Figueiredo, ElisabeteThe insects present in the blackberry and blueberry crops are still almost unknown in Portugal. Thrips and their natural enemies were surveyed in these crops, during the flowering period, in Odemira region, as well as in the weeds inside and around the crops areas. This allows an evaluation of the entomological interaction cropweeds, for a future management of weeds taking also into account crops protection aga...
A situação do ensino da protecção integrada e da fitofarmacologia em Portugal e...
Figueiredo, Elisabete; Godinho, Maria do CéuIn 2005, in the 7th National Meeting on Integrated Control, the evolution of higher education of plant protection in Portugal, in universities and polytechnic schools with agricultural sciences, was analysed as well as the curricula scenario at that date. The current state is yet well illustrated by these studies since the schools had already adopted their curricula to the Bologna Process at that time (or they ...
Coenosia attenuata (Diptera: Muscidae): um predador em estudo para utilização e...
Martins, Joana; Domingos, Cíntia; Nunes, Raquel; Garcia, André; Ramos, Cristina; Mateus, Célia; Figueiredo, ElisabeteCoenosia attenuata Stein, or “tiger-fly”, a polyphagous predator of important agricultural pests, as larva and adult, was detected for the first time, in Portugal, in 2002, in the “Oeste” region. For mass rearing optimization, the methodologies described in literature were changed. A higher number of emergences occurred on substrates with higher number of sciarids larvae and on the substrate with soil mixed wit...
Impacto da traça-verde Palpita vitrealis (Rossi) em diferentes cultivares de ol...
Mateus, Helena; Figueiredo, Elisabete; Luz, João Pedro; Silva, Maria do Céu; Mexia, AntónioThe attacks of jasmine moth were monitored in three olive cultivars, ‘Arbequina’, ‘Cobrançosa’ and ‘Galega Vulgar’, in a five years old olive grove and also in a plot of ‘Galega Vulgar’ one year old near Belmonte. The observations were carried out in 2000, from April 5 to November 7 and the first symptoms were observed on July 7. ‘Cobrançosa’ was significantly less attacked throughout the observation period and...
Estimativa do risco de traça-verde Palpita vitrealis (Rossi) amplificada por co...
Mateus, Helena; Pereira, Cândido; Cardoso, Miguel; Manteigas, Ana; Sequeira, Manuel; Figueiredo, Elisabete; Luz, João Pedro; Mexia, AntónioJasmine moth population was monitored in olive groves in Cova da Beira, using traps baited with three commercial formulations of pheromone: Russell (in tricoloured funnel traps), SEDQ and Suterra (both in delta traps). Counts were carried out weekly from March to November 2010 for SEDQ’s pheromone and from September to November for Russell’s and Suterra´s pheromones. The scouts ranged among 0 and 4 insects/trap...
Parasitismo oófago de traça-do-tomateiro por Trichogramma evanescens (Hymenopte...
Payer, Rosângela; Mexia, António; Pratissoli, Dirceu; Figueiredo, ElisabeteTuta absoluta eggs were evaluated as host for Trichogramma evanescens with the aim of using indigenous species for biological control of the South American tomato moth. After being proved that T. evanescens could parasitize and achieve the complete development inside this host, parasitism rate, proportion of eggs within the parasitoid that reach the adult stage and viability of development rate, at three differ...
Armadilhas de feromona sexual com luz para captura em massa de Tuta absoluta (M...
Matos, Tiago; Figueiredo, Elisabete; Mexia, AntónioIn an assay performed in November 2010, adults captured in sexual pheromone water traps with and without light were counted. In traps with light a part of the insects were sampled for sex identification. Water traps for mass trapping which combined the attractive effect of sexual pheromone and light captured higher levels of Tuta absoluta adults than the traditional ones, with pheromone bait only. However, thes...
