- The Pervermac II Project and Its Actions Regarding the Sustainable Use of Pesticides on Agricultural Production, Food Safety and Consumers Health in AzoresPublication . Lopes, David João Horta; Fernandes, Paulo; Aguiar, Andreia; Dias, Ana; Bettencourt, Maria; Tarantino, ElisaThe overall objective of Pervermac II project is to promote a sustainable use of pesticides in the agricultural production and ensure food security in the Macaronesian region (Azores, Madeira, Canaries and Cape Verde). The aim is to ensure farmer’s safety and health with special regards to those who apply pesticides in field through the quantification of residues level in the vegetable and fruits locally produced and imported and, at the same time, decreasing environmental contamination which could represent a risk for consumer health. The level of residues in agricultural products collected during the last four years (2017 to 2020) were been analysed in order to safeguard food safety for the Azorean population. There were also made food surveys to obtain the real proportion of vegetable and fruits in our diet and the correlated level of pesticides residues in the food intake by humans. On most of the products analysed, no pesticide residues were found. Pesticides residuals were found only on a small portion and in this case, the limit allowed by law was never been reached. Activities to raise awareness about the adoption of good diet and promoting actions concerning the implementation of organic production and consumption were conducted with students and Azorean consumers. Actions of knowledge increasing and technology transfer to farmer and the technicians ensured the adoption and implementation of integrated protection measures, promoting the sustainable use of pesticides by the farmers that implemented alternative means of protection against the major crop’s phytosanitary problems. This work has been funded by the European Fund for Regional Development (FEDER), articulated through the Territorial cooperation MAC 2014-2020.
- Monitoring ten insect pests in selected orchards in three Azorean Islands : The project CUARENTAGRIPublication . Lamelas-López, Lucas; Borges, Paulo A. V.; Tarantino, Elisa; Juliano, Maria M.; Fontes, José C.; Moules, Cristina A. R.; Rodrigues, Ricardo; Machado, Jessica; Mota, José A.; Sousa, Beatriz; Amaral, Helder; Filipe, Maria da Conceição; Lopes, David João HortaBACKGROUND: The data we present are part of the CUARENTAGRI project, which involves all archipelagos of the Macaronesia (Azores, Madeira, Canary Islands and Cabo Verde). The project aims to: i) identify and evaluate the risks associated with the introduction of new arthropod pests; ii) study the population dynamics of selected arthropod pest species currently responsible for the damage of key target crops and iii) develop monitoring systems, based on prediction and/or population dynamics of the crop pests, creating warnings and a phytosanitary prevention system. In this contribution, we compile data for three Azorean Islands (Terceira, São Jorge and São Miguel Islands), where pheromone-baited traps were placed in pastures, potato fields and several orchards’ types (apples, banana, chestnuts, olives, orange and strawberry), during three consecutive years (2020, 2021 and 2022). NEW INFORMATION: A total of 114,827 specimens of insects (Arthropoda, Insecta) were collected, belonging to four orders, six families and ten recorded pest species. A total of eight species are considered introduced (Cosmopolites sordidus (Germar, 1824), Drosophila suzukii (Matsumura, 1931), Bactrocera oleae (Rossi, 1790), Ceratitis capitata (Wiedemann, 1824), Phthorimaea operculella (Zeller, 1873), Cydia pomonella (Linnaeus, 1758), Cydia splendana (Hübner, 1799) and Grapholita molesta (Busck, 1916); n = 84,986 specimens) and two native non-endemic (Mythimna unipuncta (Haworth, 1809) and Spodoptera littoralis (Boisduval, 1833); n = 17,465 specimens). This study intended to contribute to a better knowledge of the arthropods pests that can affect the Azorean crops and will serve as a baseline for future monitoring actions, pest risk assessments and prevention systems.
- Contribution to the study of the beneficial fauna of olive orchards in Porto Martins, Terceira Island, AzoresPublication . Moules, Cristina Alexandra Rocha; Tarantino, Elisa; Lopes, David João Horta; Borges, Paulo A. V.The olive tree culture in Terceira Island occupies a strip in Porto Martins area whose fruit is very sought, mainly by tourists and restaurants. The olive tree is very affected by pests, such as the olive fly, which causes high losses and a drastic loss of production. Therefore, large quantities of pesticides are applied whose applications have a great impact, in particular, on beneficial organisms. In this work, the beneficial fauna present in olive groves was identified through the technique of beatings. The impact of the application of pesticides on these beneficial insects present in olive trees with different levels of treatments was also evaluated. For this, orchards with intensive applications, with less intensive applications and one organic orchard were selected to studied and monitoring. It was verified that in the olive groves with intensive and semi-intensive pesticide applications the abundance of beneficial insects was unbalanced, with a low abundance of predatory insects and still high population densities of the olive cottonweed pest. The results obtained point to the fact that chemical treatments do not destroy the target pests and worst contribute to a reduction in auxiliary organisms. In the organic orchard was observed the highest abundance of predatory insects and the lowest abundance of herbivorous insects. These results showed that this type of orchard is in a natural balance and that this is the way to follow in preserving the presence of beneficial insects in the olive parcels because these are very important to keep low pest populations and permit its better control. The conclusions of this study point to the fact that producers can further increase their yield by taking the biological option in their daily practices that will have a lower impact on the beneficial fauna present in the olive groves. At the same time will also permit to preserve the environment and the health of the applicators, producers and of the consumer by obtaining a product without any pesticide residues.
- The Fruit Fly Protect project and its actions regarding the evaluation of different traps and attractants for Ceratitis capitata Wied. in AzoresPublication . Lopes, David João Horta; Costa, V.; Tarantino, ElisaThe Mediterranean fruit fly (Ceratis capitata Wiedemann) (Diptera: Tephritidae) is one of the most important pests for fruit and vegetable production because of its ability to damage fruits and adapt to new environments. This study aimed to compare different traps, namely Cera Trap® (Bioiberica) filled with food attractant and Tephri trap baited with Econex Trypack® for C. capitata monitoring. C. capitata adults were collected during three years (2018–2020) in citrus orchards on three different islands of the Azorean archipelago: Terceira, S. Miguel and S. Jorge. The results show only a statistical difference in 2020 for São Miguel Island in Tephri Trap. Cera Trap showed good results in terms of capture when population densities are high and it is, therefore, a good tool to control this pest but at low C. capitata densities, Tephri trap with Trypack represents a good control device.
- First finding of Sophonia orientalis (Matsumura) in the AzoresPublication . Tarantino, Elisa; Ros-Prieto, Alejandra; Lopes, David João Horta; Borges, Paulo A. V.Sophonia orientalis (Matsumura) (Hemiptera; Cicadellidae) is native to South-East Asia and is a highly polyphagous pest, considered an invasive pest, that affects crops as well as endemic plants. This paper presents the first report of S. orientalis in the Azores (Portugal). The first individuals were found in 2018 in the botanic garden on Terceira Island and later in 2020 in banana orchards. In 2020, S. orientalis was found in Pico Island in mixed forests.
- Flowering Coriander (Coriandrum sativum) Strips Do Not Enhance Ecosystem Services in Azorean OrchardsPublication . Ferrante, Marco; Lövei, Gabor; Lavigne, Lambert; Caballero Vicente, Mario; Tarantino, Elisa; Lopes, David João Horta; Monjardino, Paulo; Borges, Paulo A. V.ABSTRACT: Ecosystem services (ESs) and disservices (EDs) are routinely estimated from changes in service provider densities without measuring their actual levels. By using the sentinel approach (i.e., exposing a plant, seeds, and prey models in a standardized way), we tested how coriander (Coriandrum sativum) strips planted in mixed orchards on Terceira Island (Azores, Portugal) affected ESs/EDs via herbivory on lettuce plants, seed predation on wheat and weed seeds, and predation on artificial caterpillars. Vertebrates had more influence than invertebrates on ESs and EDs. Herbivory (ED) after 2 weeks was similar in the coriander and the control plots, while seed predation was higher in the control than in the coriander plots on both wheat grain (an ED: 30.8% vs. 15.3%) and weed seeds (an ES: 2.5% vs. 0.4%). Vertebrate predation (ES) rates after 48 h were significantly higher in the control (9%) than in the coriander plots (3%), while no difference was observed for invertebrate predation. Coriander strips did not support increased ES/reduced ED levels in this habitat. The sentinel approach is effective to quantitatively compare multiple ESs/EDs under different farming management strategies.
- Efficacy of two traps and three different pheromone-based attractants to control the banana weevil adults Cosmopolites sordidus (Coleoptera: Curculionidae) in banana orchards on Terceira Island, Azores.Publication . Lopes, David João Horta; Tarantino, Elisa; Moules, C.ABSTRACT: The banana borer weevil, Cosmopolites sordidus (German) (Coleoptera: Curculionidae), is considered an important pest of bananas. It is extremely specific to Musaceae (Musaceae: Musa species). The efficacy of the different combination of traps and attractants on the banana weevil is important to been investigated to identify the best combination to use in banana orchards on Terceira Island (Azores). For that purpose, an essay was conducted during two years (2021 and 2022) to determine the efficiency of two traps (Cosmotrack and Stopweevil) and three attractants containing sordidin pheromone (Cosmogel NovAgrica, CosmoPlus Scyll’Agro and EcoSordidina 90K Ecobertura) to monitor C. sordidus populations in two banana orchards. The trap contents were collected every 15 days in 2021 for all the year (January to December). In 2022 the same two traps (Cosmotrack and Stopweevil) and only two different attractants (Cosmogel NovAgrica and CosmoPlus Scyll’Agro) were tested for 5 months (from January to May). The results from both essays suggest that Cosmotrack with Cosmoplus is the more suitable best combination trap and attractant for the control of C. sordidus. We also found significant differences in the banana weevil adult captures between the two traps and the three attractants considered in two orchards. Significant difference was found between Cosmotrack with Cosmoplus and Cosmotrack with Cosmogel, and when between Cosmotrack with Cosmoplus regarding all the other trap and attractant combinations tested.
