The main purpose of these study was to evaluate the composting period as previous treatment in the worms diet and in their subpopulations development. Two tipes of dung (cattle and sheep) mixed with pruning remains and in four pre-composting times (14, 21, 30 and 45 days) were evaluated. The purpose of these mixtures was to adjust the C:N ratio, seeking to make it as close to 30:1 as possible. At the time of composting the parameters of temperature, humidity and pH were monitored. Each experimental unit consisted of 10kg of substrate and 50 clitellate worms. Each experimental unity was represented by 10 kg of substrate or pre-compost was inoculated with 50 cliteled worms. To evaluate population dynamics, they were counted every 2 weeks for a period of 2 months from the date of inoculum. The results show that; in the first census, the cocon subpopulations were favored mainly by cattle manure with pruning remains subjected to a 45-day composting period. In the second census, the best result in the increase of coconuts was given by the vacuum manure with pruning remains subjected to a composting period of 21 days. In the third census, it was shown that the cocon subpopulations and juveniles responded better to cattle manure with pruning remains subjected to 14 days. Finally, the fourth census indicates that the subpopulations of cocones were favored from the vacuum manure with pruning remains subjected to a composting period of 21 days; subpopulations of juveniles and adults, were benefited, with the same substrate, subjected to a composting period of 14 days. It is concluded that the best composting period ranged between 14 and 21 days, manifesting itself in the position of cocones, development of juveniles and increase of clitelated adults. The substrate that had the best results in the subpopulations of Eisenia fetida was cattle manure with pruning remains. Additionally, the values obtained from the physical-chemical characterization analysis of the vermicompost are within what is required by the NTC-2011 in the use of fertilizers and organic amendments for crops.
