Avaliação reprodutiva e adaptativa das minhocas Elsenia andrei (Bouché, 1972) e Euddíus eugenlae (Kinberg. 1867) cultivadas em diferentes. substratos.

Abstract

The increasing Brazilian population demande—d a high demand for food production, conse—quently the waste also occurs on a larger scale generating domestic organic waste - RODS in important quantities. Many of these RODs can be reused and reverted to soil nutrition because they are mostly organic material that, when used for landfills and landfiils without any previous treatment, end up causing serious environmental problems, The objective of this work was to evaiuate the reproductive and adaptive process of two species of oiigochaetes: Eisenr'a andre-i (Bouche, 1972) - California red and Eudniius eugeniae (Kinberg, 1867) — African giant. in different substrates to identify the species that best adapte as well as the substrate that offers better biological conditions for the earthworm. The experiment started in August 2015, with two evaluation dates for each species and each type of treatment (30 and 60 days) and different population levels (0. 10 and 15 worms of each species), using treatments composed of: (50% bovine manure and 50% ROD), (75% ROD and 25% sawdust) and (100% goat manure). The data were duty recorded and submitted to statistical treatment. The results were different from the 30-day evaluation for the Eisenia andreia worm species. There was greater reproduction in the material composed of sawdust and ROD, however, at 60 days this treatment was overcome by 50% bovine manure and 50% ROD, with a better reproduction and adaptation to this treatment. The goat manure did not obtain satisfactory results, verified by the little reproduction. The Eudrilus eugeniae worm species did not show any favorable development in any of the treatments used, due to absence of reproduction, escape! death and humus production in comparison to the other species studied. ln view of the results obtained, it can be suggested for use in the domestic composting process, the Eisenia andrei species as the most appropriate, in order to be able to consume different substrates. taking advantage of a higher percentage of domestic organic waste produced.
