Effects of croton urucurana extracts and crude resin on Anagasta kuehniella (Lepidoptera: Pyralidae) BABT
Silva,Luciana Barboza; Silva,Walciane; Macedo,Maria Ligia Rodrigues; Peres,Marize Terezinha Lopes Pereira.
Hundreds of plant species have been studied in order to find out the active ingredient responsible for their insecticidal activity against the pests of economic importance. To verify the insecticidal activity in the husk of stem of Croton urucurana Baillon 1864 (Euphorbiaceae) against Anagasta kuehniella Zeller 1879 (Lepidoptera: Pyralidae), the methanolic (EMeOH) extract, dichloromethane fraction (FDM), ethyl acetate fraction (FAE) and crude resin, incorporated into an artificial diet were evaluated. EMeOH (0.5, 1.0 and 2.0%) and crude resin (2.0%) interfered with neither the weight nor the survival of fourth instar larvae and other analyzed parameters. FDM (2.0%) fraction caused mortality of 65%, and the artificial diet containing 2.0, 1.0 and 0.5% FAE...

Abstract Brazil has high diversity of native fruits with high nutritional and biochemical value. Bactris setosa Mart. (tucum-do-Pantanal) stands out by its oil-rich almond. This study aimed to determine the physicochemical characteristics of tucum-do-Pantanal almond and its by-products: press cake and crude oil. The almond of tucum-do-Pantanal had total weight of 0.81g, lager diameter 10.87mm, small diameter 8.21mm, height 12.50, weight of almond 0.38g, weight of endocarp 0.25g. In relation to the chemical analysis, the cake had higher ash, protein and carbohydrate contents than the almond. On the other hand, the content of moisture, lipids and calories were higher in the almond. The press cake showed 636.80 g kg-1 of total fiber. The fatty acids that...

Control of papaya fruits anthracnose by essential oil of Ricinus communis BABT
Siqueira Júnior,César Luis; Freire,Maria das Graças Machado; Moreira,Antônio Sérgio Nascimento; Macedo,Maria Ligia Rodrigues.
The aim of this work was to investigate the potential of castor oil for the control of papaya diseases caused by the fungus Colletotrichum gloeosporioides and the bacterium Pseudomonas caricapapayae. The treatment with 1% castor oil did not significantly affect the fungal growth. The effectiveness of castor oil for the control of anthracnose was shown when 5% and 10% (v/v) were used in the assays resulting in reduced mycelial growth. Fungal sporulation was strongly inhibited at 10% (v/v) concentration of essential oil. The studies with the fresh fruits treated with 5% (v/v) castor oil in aqueous emulsions resulted in effective reduction of pathogen spread in these fruits. No lesion was found in the fruits treated with oil, when compared to the control...

Proteins of Bacuri almonds: nutritional value and in vivo digestibility Ciênc. Tecnol. Aliment.
Lima e Silva,Magalli Costa Barbosa; Hiane,Priscila Aiko; Braga Neto,José Antônio; Macedo,Maria Ligia Rodrigues.
Bacuri (Scheelea phalerata Mart.) is a type of palm fruit tree widely distributed in the Brazilian Cerrado. The objective of this paper was to study the almonds of bacuri, in their form in natura and processed, focusing on their nutritional value through the profile of amino acids, anti-nutritional factors and in vivo digestibility. Raw and toasted samples of the almond presented a high level of proteins and fiber. Proteins of raw bacuri almond showed no limiting amino acid when compared to the ones recommended by FAO/WHO, and histidine was the most limiting essential amino acid in the toasted almonds. The almond of bacuri does not present anti- nutritional factors. In an assay with rats fed with control (casein), tests (bacuri almond flours) and aproteic...

Conservação pós-colheita de guavira (Campomanesia sp.) Rev. Bras. Frutic.
Campos,Raquel Pires; Hiane,Priscila Aiko; Ramos,Maria Isabel Lima; Ramos Filho,Manoel Mendes; Macedo,Maria Ligia Rodrigues.
Este trabalho foi realizado com o objetivo de avaliar a conservação pós-colheita de guavira (Campomanesia sp.), em função da utilização de 1-MCP e de atmosfera modificada passiva, além do armazenamento à temperatura ambiente e a 11ºC. Os frutos foram colhidos no ponto de maturidade fisiológica, subdivididos em parcelas e submetidos à aplicação de 1-Metilciclopropeno (1-MCP) (700 ηL.L-1/12horas) e à atmosfera modificada passiva por meio do uso de embalagem plástica. Foram realizadas análises de perda de massa, sólidos solúveis, acidez titulável, vitamina C, fenóis totais, atividade antioxidante e aparência geral dos frutos. O uso de 1-MCP não reduziu a perda de massa dos frutos, tanto em armazenamento ambiente quanto refrigerado, o que foi verificado com o...
