Producción de larvas de moscas (Musca domestica L.) con diferentes proporciones de cachaza y gallinaza

Abstract

El efecto de la combinación de diferentes proporciones de cachaza y gallinaza a diferentes alturas en magentas, se evaluó en un diseño bifactorial completamente aleatorizado: Factor 1- cantidad de sustrato (cachaza y gallinaza, %), Factor 2- altura del sustrato en la magenta (tres y cinco, cm). A- 100 cachaza; B- 25 % gallinaza + 75 % cachaza; C- 50 % gallinaza + 50 % a cachaza; D- 75 % gallinaza + 25 % cachaza; E- 100 % gallinaza a tres centímetros de altura y E, F, G, H, I con las mismas proporciones de sustratos a cinco centímetros de altura. Cada interacción se replicó tres veces. Los análisis estadísticos correspondientes se realizaron para P <0,05 a P <0,01. No influye en el rendimiento de larvas de moscas las proporciones de sustratos con la altura de los mismos. Las larvas de moscas se desarrollan entre las temperaturas ambiente de 12,50 oC y 30,40 oC con humedades relativas entre 42,0 % y 75,0 %. El mayor rendimiento de larvas de moscas se obtuvo con las proporciones mayores de gallinaza de 75 % y 100 %, influenciado por el número de larvas. No se encontró Salmonella spp en los sustratos ni E. coli. Palabras clave: Alimento, bacterias, peso, temperatura, tratamiento. Abstract The effect of the production of fly larvae in different substrates at different heights was evaluated. For this, a completely randomized bifactorial design was established with the following factors: Factor 1 – quantity of substrate (filter cake and hens manure, %), Factor 2 - height of the substrate in magenta (three and five, cm). A- 100 filter cake; B- 25% hens manure + 75% filter cake; C- 50% hens manure + 50% filter cake; D- 75% hens manure + 25% filter cake; E- 100% hens manure at three centimeters in height and E, F, G, H, I with the same proportions of substrates at five centimeters in height. Each interaction was replicated three times. The corresponding statistical analyses were performed for P <0.05 to P <0.01. The proportions of substrates with their height not influence the yield of fly larvae. Fly larvae develop between ambient temperatures of 12.50 oC and 30.40 oC with relative humidity between 42.0% and 75.0%. The highest yield of fly larvae was obtained with the highest proportions of chicken manure of 75% and 100%, influenced by the number of larvae. Salmonella spp were not found on the substrates neither E. coli. Keywords: Food, temperature, treatment, weight, bacteria.
