The Collembola have cosmopolitan distribution, numerically and occupy second place in edaphic
mesofauna, the living spaces of the soil (micro and macro pores), were low with 3 mm in length
may reach 6 to 7 mm, influencing micro fauna composed of fungi and bacteria that make the
mineralization and decomposition of nutrients contained in organic matter, the fundamental
processes continued productivity of the terrestrial ecosystems. The experiment was conducted
in the field and the laboratory of Biological Sciences at the Universidade Estadual de Mato
Grosso do Sul (UEMS), Unit of Dourados-MS, and in the laboratory of Entomology of Experimental
Center of Agricultural Sciences, Universidade Federal da Grande Dourados (UFGD). Taking
into consideration the importance of training in the process of mesofauna soil, the main objective
was to complete the survey population, quantifying and identifying the genera and families of
Collembola in no tillage system with oats. Collections were made during the months of April to
July 2006. The collections and extraction of Collembola were made in the range of 5 cm deep,
with a proportion of soil from 144,44 cm³ using the funnel of Berlese changed. In 3 of 50x50m
plots were withdrawn 3 in soil samples randomly classified as Latossolo Vermelho Distroférrico.
The samples were submitted to extract a table exhibiting for a period of seven days. Then the
bodies were identified and quantified, with the aid of optical and microscope. Based on the
results obtained there has been a major population of Collembola in collecting 01, featuring
3744 organisms/m2, collecting 02 with 2196 organisms/m2 and collecting 03 and 04, 648
organisms/m2 both. According to the data found the first collection presented greater population
and wealth of edaphic Collembola. Of the genera identified the family was the predominant
Entomobrydae, which found its representatives were the genera Lepidocyrtus spp and Seira
spp, these two genres have more morphology, as antenna, legs, and wishbone epiedaphic
prefer to live in the region, coming to the food litter on the ground. Two other families were found
Paronellidae and Oncopoduridae, with its representatives Troglopedetes genera spp and
Oncopodura spp, respectively. These are considered hemiedaphics or euedaphics are
completely susceptible to the conditions edaphic. The highest rates were observed population
when environmental conditions, especially the humidity, were more favorable. The reduction of
soil moisture due to lower rainfall in the months of collections showed that the number of
organisms/m2 population of edaphic Collembola suffered decline highlighted the fact in the last
two collections. MenosThe Collembola have cosmopolitan distribution, numerically and occupy second place in edaphic
