El objetivo del presente estudio fue utilizar herramientas de la neurogastronomía y neuromarketing para estudiar las emociones y preferencias visuales de los consumidores hacia hojuelas de papas (Solanum tuberosum) nativas y clásicas. Se utilizaron dos tipos de hojuelas frita, papa clásica y papa nativa, con un costo de S/ 6,60 (1.79 USD) y S/ 7,00 (1.90 USD), respectivamente. En una primera etapa se utilizó la tecnología de Seguimiento Ocular y el Análisis de Emoción utilizando una aplicación para teléfono móvil. En una segunda etapa, cada participante respondió una encuesta cognitiva, mediante el uso de formulario Google. Se utilizaron 100 consumidores con edades entre 14 y 63 años. La encuesta mostró que un 45% de los consumidores mostraron su intención de comprar el producto nativo más que el producto clásico. Los resultados de neuromarketing mostraron principalmente una mayor proporción de neutralidad, y un poco menor, en emociones negativas de “escepticismo”, “tristeza” y “disgusto”, especialmente sobre el factor nutricional y el precio. Estos resultados, más que contradictorios son complementarios, ya que las herramientas tecnológicas nos permiten conocer más detalles de las preferencias y elecciones. Los consumidores pretenden consumir más productos nativos, siempre que sean más nutritivos, más sustentables, más baratos y beneficien al productor local.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42957252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The virus has been reported in Brazil and Colombia, and is usually found in mixed infections, and in plants affected by Cassava Frogskin Disease (CFSD), an endemic cassava disease in the Americas. Genome analysis of CsTLV identifies a gene in RNA2 implicated in pathogen movement in other torradoviruses. This gene (RNA2-ORF1) and another one no related to virus movement (Maf/Ham1) were amplified by PCR and cloned into constructs under the 35S promoter of cauliflower mosaic virus (CaMV), which then were transfered to agrobacterium binary vectors. When agro-infiltrated in Nicotiana benthamiana plants, only RNA2-ORF1 had a positive effect on the mechanical inoculation of cassava virus X (CsVX), a potexvirus that has a low rate of mechanical infection in N. benthamiana. Efficiency of CsVX mechanical transmission was measured by the number of infected plants, presence of symptoms, and titers of CsVX as measured by ELISA, two weeks after infection. On average, CsVX could infect 2.3 times more plants when these were previously agro-infiltrated with A. tumefaciens binary vector encoding CsTLV RNA2-ORF1. We conclude that the novel secovirid CsTLV associated with leaf spot symptoms in cassava, encodes a gene that could enhance other viral infections in N. benthamiana. Further studies are required to elucidate this effect and its role in mixed infections, often observed in cassava plants affected by CFSD.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45337955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Coleoptera: Curculionidae) for several years. Despite its importance, the behavior of the black weevil in Ecuador is not well comprehended presently. Therefore, this study aimed to predict infestation patterns of the black palm weevil in Ecuador using a mathematical model based on monitoring data. Data on the number of insects per trap from a commercial oil palm farm in Quinindé, Ecuador, was collected every two weeks for five years (2016-2020) and analyzed using the Classical Fourier (CF) spectrum and the Dickey-Fuller test to determine seasonality. The trend component of the data dropped from 16.33 in January 2017 to 11.96 in January 2019, with a fluctuation ranging from -0.11 to 2.50 observed for the entire data set. The results obtained after fitting the model ranged from -0.11 to 3.19, with a maximum of 5.30. The augmented Dickey-Fuller (ADF) test for the black weevil time series yielded a result of -5.60 (P<0.01). The partial autocorrelation ranged from -0.35 to 0.1. Based on our model, we projected the occurrence of black palm weevil from 2021 to 2024, with a fluctuation in the number of insects per trap ranging from 12.68 in January 2021 to 13.023 in November 2023. This model can be used to predict future insect occurrences in Ecuador, providing valuable insights into the behavior of the black weevil and using it for effective development control measures for this pest.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47448908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to develop an adsorbent from plantain peel, using a simple procedure, and to evaluate its capacity to remove phosphate from aqueous solutions at phosphate concentrations similar to those of water sources at risk of eutrophication (0.30 mg/L). The simple pyrolysis method was used in an electric muffle, without chemical activation, using plantain peel as precursor. The variables evaluated were pyrolysis temperature and solution pH. The specific surface area BET, zero loading point of the developed treatments, was determined. Phosphate adsorption was studied in a batch experiment in the presence of calcium ions in solution. Phosphate adsorption was favorable at all three pyrolysis temperature levels (500, 600 and 700 °C) and two solution pH levels (pH 7 and 10). the pseudo-second order kinetic model was the best fit for the experimental data to describe the adsorption mechanism. The best fit to the experimental equilibrium data was obtained with the Langmuir isotherm model. It was found that a 1 g/L dose of the adsorbent was able to reduce 92% of phosphate in water, with a removal capacity 0.14 mg/g at pH 10 and pyrolysis temperature of 700 °C.

Tree biometric parameters (height, diameter, biomass) and N, P, K, Ca, Mg, Fe, Cu, Mn, Zn foliar concentrations were determined during early the growth of teak. Treatments with addition of dolomite lime favored higher biometric parameters, and use of organic fertilizers promoted more growth than inorganic fertilizers. In the case of nutrients, no major differences were observed between limed and unlimed treatments while organic fertilizer promoted Ca, K and S nutrition.

However, due to the raw materials used, the compost can have a significant content of heavy metals such as: cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and selenium (Se), and contaminants such as potentially toxic trace elements that harm human health. These components can accumulate in plant tissues by absorption, giving rise to the possibility of being bioavailable to humans and animals. The fungal bioremediation of heavy metals in RSOM/U compost is highly efficient, cost-effective, available and friendly to the environment, therefore the removal of metals through this technique is a priority, if the purpose is to use it in agricultural soils. This review summarizes the studies based on the potential of fungal biomass for the bioremediation of heavy metals in RSOM/U compost, reporting information on RSOM/U-based compost, fungal biomass production and mechanisms of bioremediation of heavy metals by fungal biomass. In conclusion, the bioremediation of heavy metals using the fungal biomass in RSOM/U compost, with adequate segregation of raw material, coupled with bioremediation, could improve the removal of heavy metals in RSOM/U compost, and could be an ecological and viable alternative, which must be valued by intensifying its use.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43468104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
