          Abstract

          Resumen Objetivo. Evaluar la producción de larvas de moscas en borra de café en combinación con gallinaza a dos alturas en magentas en un moscario. Configuración y Diseño. Diseño bifactorial completamente aleatorizado con dos factores: Factor 1-cantidad de sustrato (borra de café y gallinaza, %), Factor 2- altura del sustrato en la magenta (tres y cinco, cm). A- 100 % borra de café; B- 25 % gallinaza + 75 % borra de café; C- 50 % borra de café + 50 % gallinaza; D- 75 % borra de café + 25 % gallinaza; E- 100 % gallinaza a tres centímetros de altura y E, F, G, H, I, J con las mismas proporciones de sustratos a cinco centímetros de altura, replicados seis veces. Materiales y Métodos. En cada combinación se midieron las temperaturas en sustratos y ambiente en moscario por la mañana y tarde, la cantidad y peso de las larvas de moscas cosechadas al noveno día y su rendimiento; y la presencia de Salmonella y coliformes fecales. Resultados. La temperatura en los sustratos (34,50 oC - 37,10 oC). fue superior al ambiente (17,80 oC – 34,2 oC) en todo el período. El rendimiento tuvo influenciado por el número de larvas, que fue mayor para el tratamiento E y J con 12,302 y 21,765 g kg-1, respectivamente y no por el peso de las larvas que no difirió. Conclusiones. La inclusión de borra de café en diferentes proporciones con la gallinaza no posibilita la obtención de larvas de moscas.

          Abstract Objective. To evaluate the production of larvae of flies in coffee grounds in combination with layer manure at two heights in magentas in a moscario. Configuration and Design. Completely randomized bifactorial design was established with the following factors: Factor 1 - quantity of substrate (coffee grounds and layer manure, %), Factor 2 - height of the substrate in magenta (three and five, cm). A- coffee grounds 100%; B- layer manure 25% + coffee grounds 75%; C- coffee grounds 50%+ layer manure 50%; D- coffee grounds 75% + layer manure 25%; E- layer manure 100% at three centimeters in height and E, F, G, H, I, J with the same proportions of substrates at five centimeters in height. Each interaction was replicated six times. Materials and Methods. In each combination the temperatures were measured in substrates and ambient temperature in moscario at morning and afternoon, the quantity and weight of the larvae of flies harvested to the ninth day and their yield; and the presence of Salmonella and faecal coliforms. Results. The temperature in the substrates (34.50 oC – 37.10 oC). went superior to the ambient (17.80 oC – 34.2 oC) in the whole period. The yield had influenced by the number of larvae, that was bigger for the treatment E and J with 12.302 and 21,756 g kg-1, respectively and not for the weight of the larvae that didn't differ. Conclusions. The inclusion of coffee grounds in different proportions with the layer manure doesn't facilitate the obtaining of larvae of flies.

              Conversion of organic wastes into fly larval biomass: bottlenecks and challenges

              The large volume of organic wastes and by-products produced every year usually generates environmental problems, such as water, air and soil contamination and it can be also a focus for pathogen dispersion. Sustainable waste management strategies should be developed, that can favour the value of the organic waste instead of its disposal. A sustainable strategy would be the use of the organic waste as substrate for intensive production of insect biomass. The insects associated with manure and organic waste can play a key role for the sustainable valorisation of organic waste streams as high add value products as they could be used as feed. This review is an overview of the research related with intensive insect farming of saprophagous dipteran species (flies) on manure and other organic wastes and the by-products obtained after the process. Using dipterans as recyclers of waste means that the mass-production systems of these organisms have to be efficient and competitive with other recycling systems. This review describes the possibilities of the dipterans to become active agents in waste management systems and, at the same time, an important resource of protein for feed and the main aspects and bottlenecks that have to be improved in order to achieve competitive insect farming.
