“…Lithobiida and Julida were significantly affected by tillage in the first month of sampling but, in the latter 3 months, both groups were reduced regardless of treatment. Centipedes are effective predators in agroecosystems ( Brust & House, 1990 ) and the results of the present study suggest that tillage may decrease potentially beneficial effects of predators early in the growing season. Centipedes and millipedes can also influence a number of soil processes, including the mixing of organic and mineral particles, the creation of biopores, the promotion of humification and redistribution of microorganisms throughout the soil ( Hendrix et al , 1986 ).…”

1 Tillage, commonly used in agroecosystems, can influence the abundance of invertebrates through factors such as habitat change and food availability. 2 The effects of tillage on the composition and abundance of invertebrates were examined in a vineyard near Mildura in Victoria, Australia, focusing particularly on groups that might act as natural enemies in vineyards. We used pitfall traps at ground level and sticky traps in the canopy. 3 The collections were first sorted to order. Beetles (Coleoptera) were sorted to family and ants (Hymenoptera: Formicidae) to genus. 4 Ants were the only group to be affected by tillage when all months were considered. The same genera occurred in both treatments but the abundance of several genera was reduced by tillage. Families of several beetles, including predators, increased in tilled areas. Spider, millipede, centipede and earwig numbers were decreased by tillage. In the canopy, Trichogrammatidae and other parasitoids decreased in abundance after tillage. 5 These results indicate that tillage influences the composition of invertebrates and has the potential to negatively affect the abundance of beneficial groups.

“…The no-till system drive to an increase in the ant richness, population density and foraging activities over time, which can guide to a more efficient biological control of the insects considered pests. Some authors found that the higher densities of these arthropods for controlling the crop pests reduced the number of the insecticide applications (Brust and House, 1990;Brust, 1991;Clark et al, 1994). Barbosa and Fernandes (2003) also observed greater richness, diversity, and equitability of the ant fauna in the understory areas with more complex E. urophylla.…”

“…Moreover, in this study, the biomass of spiders was enhanced significantly by untilled treatment. Several studies have reported that generalist predators, including spiders, are enhanced in untilled or reduced-tillage cropping systems in upland agro-ecosystems (Brust et al, 1985;Brust and House, 1990;Kendall et al, 1991;Symondson et al, 1996;Clark et al, 1997). Reduced-tillage cropping systems are favorable for spiders because of a richer habitat structure (more weeds and plant residues), lower disturbance, higher soil moisture, and the proliferation of detritivores (see review by Wardle, 1995;Sunderland and Samu, 2000).…”

To examine the effects of tillage practices on spider assemblages in rice paddy fields, we investigated the abundance and biomass of spiders in untilled and tilled paddy fields over three cropping seasons (from 1999 to 2001). In total, we collected 6,829 spiders, consisting of 13 species in seven families. The family Lycosidae was the most abundant, followed by Tetragnathidae, Linyphiidae, and Salticidae. Spider abundance and biomass were greater in untilled than in tilled paddies during each cropping season. Although we detected no significant effect of tillage on spider abundance, we did observe a significant effect of tillage on spider biomass in 2000 and 2001. No differences were found in the abundance and biomass of tetragnathid and linyphiid spiders during the cropping season. In contrast, the abundance and biomass of lycosid or salticid spiders tended to be larger in untilled paddies than in tilled paddies, especially later in the cropping season.
