Trioza erytreae (Del Guercio, 1918) and the Interaction with its hosts: A Review
Magalhães, Tomás Thormann Abranches de; Duarte, Amilcar; Tomás Marques, Natália; Pereira, José AlbertoThe cultivation of citrus in the Mediterranean region is of considerable economic importance. The viability of this industry is contingent upon a number of factors, with adequate phytosanitary management being of particular significance. During the last decade, the geographical range of the invasive psyllid, Trioza erytreae (Del Guercio, 1918), has expanded to the mainland territories of Portugal and Spain. Tri...
The potential risk of bactrocera dorsalis (Tephritidae) invasion into the fruit...
Wijekoon, Chandana Dammika; Duarte, Amilcar; Neto, LuísBactrocera dorsalis (Hendel, 1912) (Diptera: Tephritidae) is considered a highly invasive fruit fly species already widespread in Indo-Asia and sub-Saharan Africa. In recent years, this species has extended its range into new regions previously considered unsuitable, posing an alarming new risk for the subtropical regions of Europe. This review aimed to assess the potential risk of B. dorsalis invasion into the...
Developing epidemiological preparedness for a plant disease invasion: modelling...
Ellis, John; Lázaro, Elena; Zarcos Duarte, Beatriz; Magalhães, Tomás Thormann Abranches de; Duarte, Amilcar; Benhadi‐Marín, JacintoSocietal Impact Statement Huanglongbing (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected. By developing a mathematical model of spread in Spain, we tested surveillance and control strategies before any future HLB entry in the EU. We found while some citrus production might be maintained b...
Case study: water reuse in citrus farming - carbon emissions reduction and ecos...
Resende, Flávia C.; Silva, Manuela Fernanda Gomes Moreira da; Anibal, Jaime; Martins, António; Duarte, AmilcarAnthropogenic factors and climate change are putting increasing pressure on natural water resources, threatening habitats and biodiversity (Libutti et al.2018, Rebelo et al., 2020). Worldwide, agriculture uses around 70% of the total water used in human activities. In addition, the demand for food and animal feed production tends to increase with the growth of the world population (Parris, 2010; Becerra-Castro ...
Urban vegetation benefits in mediterranean cities for climate change adaptation...
Matias, Pedro; Silva, Manuela Fernanda Gomes Moreira da; Teigão, João; Duarte, AmilcarIn the current climate change scenario, Mediterranean cities face heatwaves and reduced availability of freshwater alternated with intense precipitation events in short periods. The demand for water, especially for urban and tourism purposes, is rising, particularly in coastal cities. The importance of integrating nature into cities, particularly trees, has been studied for its benefits in adapting to climate c...
Effect of ground cover on soil carbon storage in a citrus orchard: challenges a...
Reis, Adélia; Duarte, Beatriz; Duarte, AmilcarFruit tree crops, as a relevant agricultural sector, have great importance in the sequestration of atmospheric carbon and its stock in the soil. A vast area of citrus orchards is found in the Mediterranean region, an area prone to soil degradation and desertification. Adoption of sustainable agricultural practices, such as permanent soil cover in orchards, can contribute to maintaining their productivity, prote...
Effect of heading cuts on branch growth of ‘Encore’ mandarin
Jacinto, Catarina; Matias, Pedro; Oliveira, Cristina; Duarte, AmilcarPruning can be used for various purposes in citriculture: to control the size and shape of the trees; improve fruit size and quality; manage the alternate bearing and control diseases and pests. However, the physiological response of the tree to heading cuts it´s not well documented. To supplement the lack of studies on the effect of pruning on branch growth, a trial was conducted on ’Encore’ mandarin, in the A...
Current distribution of the African citrus psyllid Trioza erytreae in Portugal:...
Duarte, Beatriz; Poeira, Rita; Magalhães, Tomás; Paiva, Paulo; Soares, Celestino; Neto, Luís; Marques, Natália; Duarte, AmilcarThe onset of Trioza erytreae, the African citrus psyllid, in the northwest of the Iberian Peninsula (north of Portugal and northwest of Spain) caused great concern among citrus growers in Europe. This insect is a vector of the bacteria Candidatus Liberibacter spp., the causal agent of huanglongbing, one of the most devastating citrus diseases. The first report of T. erytreae presence in mainland Europe refers t...
A citricultura do Algarve e a seca: Proposta de algumas medidas de contenção.
Duarte, Amilcar; Trindade, Ana RitaNas últimas semanas a seca que está a afetar o Algarve (e algumas zonas do Alentejo) tem estado presente na maioria dos órgãos da comunicação social e tem sido alvo de discussão em todo o país. O problema levou a que os diversos órgãos do poder se tenham concentrado em falar e tomar decisões relativamente à falta de água que ameaça a economia e, eventualmente, a qualidade de vida nesta região. Independentemente...
Effect of fruit thinning on fruit quality and alternate bearing of ‘Setubalense...
Guerreiro, T.; Trindade, Ana Rita; Duarte, Amilcar; Matias, PedroCitriculture plays a major role in agriculture worldwide, especially in the Mediterranean region. However, there are limitations in citrus production. Alternate bearing can be a big problem when it is very intense. Trees produce a heavy yield one year (“on” year) and light ones the next (“off” year). During the “on” year, trees produce many small-sized fruits, while in the “off” year, they produce very few, lar...
