| The polyculture systems guarantees food to small farmers, would ensure sustainable agriculture, high productivity per unit area and lessen the natural risks of agriculture. Within this context the objective of this study was to evaluate the production cost and profitability of an organic polyculture system comprising passion fruit, maize, pineapple and cassava in association with the cover crops. This research was carried out at the Seridó Ecological Farm, in the Municipality of Rio Branco, Acre State, from 2009 to 2011, in the completely randomized block design in a split plot arrangement with three repetitions and comprised plots containing passion fruit supported by espaliers located 3 m or 4 m apart. Plots were divided into subplots containing the... |

| El presente trabajo evaluó la factibilidad técnica y económica de la implementación del control biológico de ácaros plaga de papayo en la zona productora del Centro de Veracruz. Se colectó Tetranychus merganser Boudreaux en Manlio F. Altamirano, Ver. Se incrementó sobre frijol (Phaseolus vulgaris L.) en invernadero. Se estimaron los parámetros poblacionales a cohortes de T. merganser a 19, 23, 27, 31, 33 y 35 °C y del ácaro depredador Phytoseiulus persimilis Athias-Henriot (comercial: Koppert de México, S.A.) a 27 °C en todos los casos sobre hojas de papayo, a 60 (±2)% HR y 14:10 h luz: oscuridad. T. merganser presentó valores máximos de tasa neta reproductiva (R0 = 62.38) y de tasa intrínseca de crecimiento poblacional (rm = 0.21) a 23 y 27 °C, que... |
