“…Vegetation structural complexity, including crop biomass and weed abundance which differed between the rainfall treatments, is an important determinant of arthropod abundance and diversity in agroecosystems (Honek, 1988;Lagerlöf and Wallin, 1993; Frontiers in Environmental Science | Agroecology and Land Use Systems October 2014 | Volume 2 | Article 44 | 8 Frank and Nentwig, 1995;Kromp, 1999). Correlations between arthropod abundance and crop and weed biomass suggest that the rainfall effects indirectly affect arthropods by changes on crops and weeds.…”

Climate change scenarios for Central Europe predict less frequent but heavier rainfalls and longer drought periods during the growing season. This is expected to alter arthropods in agroecosystems that are important as biocontrol agents, herbivores or food for predators (e.g., farmland birds). In a lysimeter facility (totally 18 3-m 2 -plots), we experimentally tested the effects of long-term current vs. prognosticated future rainfall variations (15% increased rainfall per event, 25% more dry days) according to regionalized climate change models from the Intergovernmental Panel on Climate Change (IPCC) on aboveground arthropods in winter wheat (Triticum aestivum L.) cultivated at three different soil types (calcaric phaeozem, calcic chernozem and gleyic phaeozem). Soil types were established 17 years and rainfall treatments 1 month before arthropod sampling; treatments were fully crossed and replicated three times. Aboveground arthropods were assessed by suction sampling, their mean abundances (± SD) differed between April, May and June with 20 ± 3 m −2 , 90 ± 35 m −2 , and 289 ± 93 individuals m −2 , respectively. Averaged across sampling dates, future rainfall reduced the abundance of spiders (Araneae, −47%), cicadas and leafhoppers (Auchenorrhyncha, −39%), beetles (Coleoptera, −52%), ground beetles (Carabidae, −41%), leaf beetles (Chrysomelidae, −64%), spring tails (Collembola, −58%), flies (Diptera, −73%) and lacewings (Neuroptera, −73%) but increased the abundance of snails (Gastropoda, +69%). Across sampling dates, soil types had no effects on arthropod abundances. Arthropod diversity was neither affected by rainfall nor soil types. Arthropod abundance was positively correlated with weed biomass for almost all taxa; abundance of Hemiptera and of total arthropods was positively correlated with weed density. These detrimental effects of future rainfall variations on arthropod taxa in wheat fields can potentially alter arthropod-related agroecosystem services.

“…Again, these species formed dense patches more frequently along the railways and were only sporadically noted along the road verges. Leguminous plants offer a high value of nectar and pollen [27], and are particularly important for bumblebees [43]; however, they also support a food niche for a variety of wild bees, e.g., Megachilidae, Anthophorinae, Colletidae, and Halictidae [56].…”

In this study, we evaluated if railway embankments and road verges create refuge habitats for bee flora across agricultural landscape. The survey was conducted in 2009-2012, in the Lublin Province, SE Poland. Data on the bee forage flora were obtained while making floristic charts along 60 transect plots × 300 m, with a total length of 18 000 m, for each type of linear structure. Forage bee flora was compared with respect to species richness, diversity, and evenness indices. The canonical correspondence analysis (CCA) was used to characterize relationship between species composition and environmental variables. The bee forage species richness and abundance were significantly greater on railway embankments than on road verges. The composition of species varied considerably; the number of bee forage species common to both habitats was only approximately 38% in entire data set. Most good-value bee forage species were recorded along the embankments of railways with an intermediate traffic volume. Bee forage species diversity benefits from the location of habitat elements (forests or meadows), primarily if the distance is <50 m. The lack of dense patches of valuable bee forage species in the road verges was related to the high density of non-nectariferous graminoids. Our results demonstrate how the value of man-made areas in an agricultural ecosystem can vary with respect to floral resources across the landscape, suggesting that it is inappropriate to generalize about agricultural systems as a whole without first addressing differences among habitats.

“…Those non-crop vegetation field boundaries (Greaves and Marshall, 1987) give intrinsic and permanent reservoir for vertebrates and invertebrates of agricultural land, but have declined from intensive agriculture. Presence of field margin strips like grassy boundaries, wildflower strips, and uncultivated crop edges or headlands with exclusion of pesticides can improve the abundance and species richness of plants, vertebrates and invertebrates (Lagerlöf and Wallin, 1993;Boatman, 1994;Frank, 1997). Many studies have often focused on the pest or potential natural enemies of invertebrate populations in the field margins (Thomas et al, 1992;Hassall et al, 1992;Lagerlöf and Wallin, 1993;Corbett and Rosenheim, 1996;Barbosa, 1998).…”

The diversity of vegetation enrichment in the weedy strips has been suggested to be higher in diversity of natural enemies than simple agroecosystems (Andow, 1983;Risch et al, 1983;Altieri and Letourneau, 1984).…”

Natural enemies play an important role to control the pest population of a crop field by killing the pest directly or indirectly by parasitism. By knowing the dispersal ability of natural enemies could be effective biocontrol tool for controlling the harmful pest. Vegetated field margins have been suggested as a shelter of natural enemies. Natural enemies like ground beetle, rove beetle, parasitoid and spider dispersal ability from the field margin to inside the oilseed rape field was analyzed by doing this study. All insects were collected from the oilseed rape fields of Southern Sweden. This study showed that parasitoid abundance was higher near the field margin compare to the deep field. Distribution of ground beetle, rove beetle and spider was almost the same all over the field. Parasitoids could be effective to control the oilseed rape pest near the field margin as a biocontrol aspect whereas rove beetle, ground beetle and spider could be a used biocontrol tools for all over the field.
