“…Habitat heterogeneity provided by the intercropped strip of green manure in O3 did not benefit small beetles known to be egg predators, particularly Bembidion spp. which are more abundant in open ground habitats than in areas with increased ground cover (Eyre et al, 2009;Bjorkman et al, 2010). Although organic systems O1 and O2 had comparable ground cover small beetles were most abundant in O2.…”

a b s t r a c tIn a field experiment, we evaluated effects of three different organic white cabbage-cropping systems (O1, O2, O3) on the cabbage root fly, Delia radicum, and its egg predators and pupal parasitoids over 3 years. The three systems all complied with regulations for organic production, but varied in external nutrient input and N-recycling, and were compared to a conventionally farmed control. One organic system (O3) included an intercropped strip of green manure between crop rows. Oviposition by D. radicum was generally not reduced in organic cropping systems. However, higher pupae/egg ratios were observed in the conventional compared to all organic systems, indicating that immature survival from oviposition to pupation was reduced under all the three organic farming practices. In organic system O2 most small coleopteran predators were recorded, but predation on fly eggs was not significantly higher in organic treatments. Pupal parasitization rates ranged from 26.5% to 59.5%, but no significant differences among farming systems were found. Although reduced D. radicum survival could not be attributed solely to natural enemies, the results indicated that organic farming practices in general contribute to the suppression of belowground pests in cabbage production.

“…Ground beetles are essential predators, thus, their movement from the borders into the field should be enhanced (Eyre et al 2009). In a study conducted by Peng and Sutton (1996) in UK ground arthropods increased in the alleys of alley cropping compared to arable control plot which was attributed to the improved microclimate due to the presence of trees.…”

Ecological benefits provided by alley cropping systems for production of woody biomass in the temperate region: a review

et al. 2012

In temperate Europe alley cropping systems which integrate strips of short rotation coppices into conventional agricultural fields (ACS) are receiving increasing attention. These systems can be used for crops and woody biomass production at the same time, enabling farmers to diversify the provision of market goods. Adding trees into the agricultural land creates various additional benefits for the farmer and society, also known as ecosystem services. However, tree-crop interactions in the temperate region have not been adequately substantiated which is identified as a drawback to the practical implementation of such systems. In order to bridge this gap, the current paper aims to present a comprehensive overview of selected ecosystem services provided by agroforestry with focus on ACS in the temperate region. The literature indicates that compared with conventional agriculture ACS have the potential to increase carbon sequestration, improve soil fertility and generally optimize the utilization of resources. Furthermore, due to their structural flexibility, ACS may help to regulate water quality, enhance biodiversity, and increase the overall productivity. ACS are shown as suitable land use systems especially for marginal sites. Based on the available data collected, we conclude that ACS are advantageous compared to conventional agriculture in many aspects, and therefore suggest that they should be implemented at a larger scale in temperate regions.

“…Specific aspects of carabid beetle diversity and distribution include e.g. spatio-temporal changes across gradients of vegetation, land use intensification or disturbance (Aviron et al 2005;Gobbi and Fontaneto 2008;Gu et al 2008;Roughley et al 2006;Yu et al 2007), effects of habitat fragmentation and isolation (Fujita et al 2008;Wamser et al 2010), and effects of land management and cropping systems (Eyre et al 2009;O'Rourke et al 2008), grasslands (Purtauf et al 2004), forests and forest plantations (Fuller et al 2008;Taboada et al 2008;Yu et al 2008). Conclusions drawn from those studies are that most carabid species can be subdivided in open land and forest species, with specialists and generalists in each group.…”

Carabid beetles (Coleoptera: Carabidae) have widely been used to assess biodiversity values of different habitats in cultivated landscapes, but rarely in the humid tropics. This study aimed to investigate effects of land use change on the carabid assemblages in a tributary valley of the Mekong River in tropical southern Yunnan, China. The study area includes habitats of traditional land use systems (rice production and shifting cultivation successions) and was dominated by natural forests until about 30 years ago. Since then, large areas of forest have been, and still are, successively transformed into commercial rubber monoculture plantations. In total, 102 species of Carabidae (including Cicindelinae) were recorded from 13 sites over different seasons, using pitfall traps, Malaise traps and aerial collectors in trees. Cluster analysis and indicator species analysis showed that three types of habitat (rice field fallows, early natural successions and natural forest) possess a degree of uniqueness in species composition. Non-metric multidimensional scaling revealed that the environmental factors explaining 80% of the total variation in carabid assemblage composition are the degree of vegetational openness of a habitat and its plant species diversity. Rice field fallows had significantly higher numbers of species and individuals than any other type of habitat and are probably dominated by species originating from other regions. Carabid assemblages of young rubber plantations (5 and 8 years) were quantitatively similar to those of forests, but without species of significant indicator value. With increasing plantation age (20 and 40 years), the number of carabid species decreased. Increasing age and a further spatial expansion of rubber plantations at the expense of forest areas will have negative impacts on the native forest carabid assemblages with strongest effects on forest specialists and rare species.
