Zonas urbanas são inseguras do ponto de vista alimentar, pois é priorizado o uso não agrícola da terra, necessitando a importação diária de alimentos, alguns com alta exigência hídrica em sua produção. O conceito Água Virtual aplica-se ao volume oculto de água em qualquer produção. É necessário conhecer esse volume para melhor gerir os recursos hídricos, ainda mais se a produção é exportada. Analisou-se a capacidade hídrica do Submédio do Vale do Rio São Francisco em suportar a pressão exercida pela agricultura convencional irrigada. A pesquisa acercou-se do conceito de Água Virtual, e calculou o volume de água virtual que é exportada a outras regiões do Brasil e do Mundo através da manga (Mangifera indica L) e da uva (Vitis sp.) mostrando-se insustentável essa atividade.

Objetivo: Caracterizar y evaluar las selecciones Ataulfo diamante’, ‘Zafiro’ y ‘Citlalli’ de mango (Mangifera indica L.), obtenidas en el programa de mejoramiento genético de mango en el Campo Experimental Rosario Izapa del INIFAP.Diseño/metodología/aproximación: Se realizó la caracterización morfológica de acuerdo a los descriptores propuestos por la UPOV. Se evaluó el comportamiento agronómico de los clones, y con los resultados de las variables se aplicó un análisis de varianza y una comparación de medias de acuerdo a Tukey con un a=0.05.Resultados: Se encontraron diferencias morfológicas entre los clones caracterizados y evaluados; las diferencias fueron en morfología del fruto, sabor y rendimiento.Limitaciones del estudio/implicaciones: El potencial productivo y la calidad de los clones de mango estará en función del manejo en campo y postcosecha que reciban los frutos.Hallazgos/conclusiones: Los clones ‘Citlalli’, ‘Ataulfo Diamante’ y ‘Ataulfo Elite’ presentan características productivas de alto potencial y registran calidad para ser considerados en programas de mejora de la productividad del cultivo en la región del Soconusco, Chiapas, México.

Mites have hostplant specifications or host plants. Mites can be destructive and deadly of which is the host plants a mango crop. Mites on mango crops will cause the leaves yellow and fall off prematurely. This is will lead to the disruption of the productivity of mango. It is necessary for research to identify the mites that infect the mango crop. The method is carried out by direct observation. Mites were taken from the surface of mango leaves later in preservation with several levels of concentration of alcohol, and polyvinyl laktofenol. Then, observed under a microscope and documented for identification purposes. Mites on the leaf surface of manalagi mango (<em>Mangifera indica</em>) found two species, it is <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> (Family: Tetranychidae, Superfamily: Tetranychoidea). <em>Oligonychus</em> sp. hallmark is rounded body shape like a spider, with a body is transparent and there are two long seta on posterior part. While <em>Oligonychus ilicis</em> has a characteristic elongated rounded body shape, red, and there is a short posterior seta. <em>Oligonychus</em> sp. and <em>Oligonychus ilicis</em> live as parasites on the surface of mango leaves that can lead to wrinkled leaves, yellow and to fall. <em>Oligonychus</em> life cycle starts from the eggs develop into Nympha and then adult.

Mango fruits `Criollo de Bocado' harvested at the mature-green stage were treated with a hydrothermic treatment of 55 °C for 3 min and stored for 20 days at temperatures of 10 ± 2, 15 ± 2 and 28 ± 2 °C. A randomized design 2 × 3 × 4 with three replications was used. Some chemical parameters were analyzed, such as total soluble solids content (% TSS), pH, tritatable acidity, and TSS/tritatable acidity ratio. TSS content increased with storage time at low temperature. The pH increased measurably with storage temperature, while tritatable acidity values results had inconsistent data.

Mango fruits `Criollo de Bocado' harvested at the mature-green stage were treated with a hydrothermic treatment of 55 °C for 3 min and stored for 20 days to temperatures of 10 ± 2, 15 ± 2, and 28 ± 2 °C. A randomized design 2 × 3 × 4 with three replications was used. Physical parameters such as color (L*, a*, b*), firmnness, and fresh weight loss were studied. Results reported that mango fruits stored at 10.2 and 15.2 °C showed the highest firmness values. Skin color changed very fast during the first storage days, while pulp color required more time to achieve mature ripe color. Fresh weight loss tended to increase with storage time and with high storage temperature. The lowest storage temperture retarded softening in mango fruits and firmnness reached the highest values.
