This work aimed to identify the species and characterize the populations performing a faunistic
analysis of Carabidae and Staphylinidae (Coleoptera) associated with soil in five areas located
in four municipalities of the Northeastern region of São Paulo State (Descalvado, Gavião Peixoto,
Guaíra e Jaboticabal). Each area was constituted by a forest fragment adjacent to a soybean
field or an orange orchard. The population survey was carried out from December/2004 to May/
2007 and the insects were sampled by pitfall traps distributed in two transects. Each transect
was 200 m length reaching 100 m in the crop field and 100 m in the forest fragment. Four traps
were set close to each other (1 m) in the edge of the crop with the forest fragment and from this
point the traps were installed each 10 m. The samplings were biweekly during the crop seasons
and monthly in the non-seasons and the traps remained in the field during one week. The fauna
was characterized by diversity, evenness, abundance, dominance, frequency and constancy
indexes. A total of 53 carabid species and 26 staphylinid species were captured in Jaboticabal
(soybean under no-tillage system). In the other areas it was captured: 47 carabid species and
32 staphylinid species in Guaíra (soybean under no-tillage system), 38 carabid species and 18
staphylinid species in Guaíra (soybean under conventional tillage system), 48 carabid species
and 24 staphylinid species in Gavião Peixoto (orange orchard) and 32 carabid species and 41
staphylinid species in Descalvado (orange orchard). Among the carabid species classified as
dominants, Abaris basistriatus Chaudoir and Selenophorus seriatoporus Putz. prevailed in five
and four experimental areas, respectively, while Megacephala brasiliensis Kirby, Odontochila
nodicornis (Dejean), Odontochila cupricollis Kollar, Scarites sp.3, Selenophorus alternans
Dejean and Calosoma granulatum Perty showed that ecological characteristic in at least two of
the studied areas. Few staphylinids species were classified as dominants: Xenopygus sp.2
reached that status in both areas with orange orchard (Descalvado and Gavião Peixoto), and
Eulissus chalybaeus Mannerheim in Guaíra (soybean under no-tillage system). The highest
indexes of species diversity and evenness for carabids and estaphylinids were observed in
areas with forest fragment and soybean under no-tillage system or orange orchard, the opposite
was observed in the soybean cultivated in conventional tillage system. Those results indicate
that the communities of carabids and estaphylinids were best structured in the areas with cultures
whose soil was not moved by cultivation. These communities contain lower number of dominant
species and most of them having similar abundances when they are compared to the community
of carabids and estaphylinids inhabiting the soybean crop under conventional tillage system.
