The composition and diversity of bees in an agricultural area in Rio Claro, state of São Paulo, Brazil, were studied from May 2003 to June 2004, using Moericke traps. The collection site, an area with 58.08 hectares, is characterized by grain production and direct planting, with 70% of the surrounding area planted with sugar cane. During the study, 456 bees were collected, distributed among 20 genera, pertaining to the families Andrenidae (4.8%), Apidae (40.8%) and Halictidae (54.4%). Specimens of genera Dialictus (38%) and Diadasia (30%) predominated in this area. The species diversity, assessed using the Shannon and Simpson indices, were H=1.88 and 1/ D= 4.15, respectively, and the Evenness index was 0.61. |

ABSTRACT Pig farming has increased in recent years, resulting in the production of a large quantity of liquid manure, which can be used as a source of organic fertiliser. The aim of this work was to determine the influence of pig slurry on the community of soil fauna in a system of direct seeding. The study was carried out in an experimental area in the town of Taquaruçu do Sul, in the state of Rio Grande do Sul, Brazil. The experimental design was of randomised blocks in a (4 + 1) x 4 factorial scheme, comprising five fertilisation treatments, 0 (no fertiliser), 20, 40 and 80 m3 of pig slurry ha-1 and one additional treatment (mineral fertiliser), with four evaluations corresponding to the number of slurry application (1st, 2nd, 3rd and 4th application),... |
