“…The numerical response (of the community of spiders) to higher pest densities was rather rapid, but as the pest densities grew, the abundance of spiders reached a threshold level. This is in agreement with previous studies conducted in different agricultural systems 48–51 . The abundance threshold in spiders can be explained by their limited dispersal rate and, in particular, their territoriality 52–54 …”

BACKGROUND Modern pest control management systems are based on the support of naturally occurring arthropod predators, as it has been shown that such predators offer an important ecosystem service. However, most naturally occurring arthropod predators are generalists (euryphagous). Their role in the biological control of specific pests has been recognized but remains poorly studied. Here, we focused on the naturally occurring arthropod predators of psyllids – the main insect pest of pear trees. We investigated the abundance of psyllids and all of their potential enemies in an abandoned pear orchard on a weekly basis from early spring to early summer. In addition, employing polymerase chain reaction diagnostics and specific primers, we investigated the predation rate on psyllids in all predators collected. RESULTS We found four predatory groups: spiders were the most abundant (60%, N = 756), followed by coccinellid beetles, anthocorid bugs and cantharid beetles. Anthocorids and spiders had the highest predation rates among the predatory groups. Among spiders, >50% of foliage‐dwelling spiders (belonging to the genera Philodromus and Clubiona; N = 206) were positive for psyllids and showed a numerical response to the abundance of psyllids. CONCLUSION We conclude that foliage‐dwelling spiders are, of the four groups, the most important natural enemies of psyllids on pear trees during spring in Central Europe, as they outnumber specialized Anthocoris bugs. © 2021 Society of Chemical Industry

“…We found evidence to support our hypothesis that habitat heterogeneity generated through cardboard bands is effective for increasing spider abundance and richness. The use of cardboard bands is an effective technique to monitor the presence of natural enemies, especially spiders (Horton et al 2001;Lombardini et al 2005;Isaia et al 2006a;Salman et al 2019Salman et al , 2020. Even more, it has been demonstrated to improve biocontrol efficiency in pear orchards (Michalko et al 2017), and it has been widely used in other plantations, such as apples, pomegranates and pecans, mainly in Europe and North America (Lombardini et al 2005; Korenko and Peka ´r 2010; Salman et al 2019).…”

“…Additionally, non-cropped fragments have a positive effect on spider abundance and diversity in soybean crops (Pompozzi et al 2019). Indeed, habitat manipulation is used to increase the number of spiders in the field, and it has been tested with different techniques, such as holes in the ground (Alderweireldt 1994), cages (Halaj et al 2000) and cardboard bands (Bogya et al 1999;Horton et al 2001;Isaia et al 2006a;Korenko and Peka ´r 2010;Michalko et al 2017;Salman et al 2019Salman et al , 2020. Halaj et al (2000) used artificial refuges for ground spiders, and showed an increase in spider abundance in these refuges compared to open fields.…”

Maintaining biodiversity in agricultural systems is essential, as it plays a key role in ecosystem services provision. However, it is declining at an unprecedented rate. Several methods can contribute to increasing species diversity in agroecosystems, including the use of artificial microhabitats. Studies focusing on biodiversity in vineyards have been carried out recently, mainly in Europe and North America, but are scarce in South America. In this study, we investigate whether introduced environmental variability and habitat complexity, using corrugated cardboard bands, enhances spider abundance and diversity in vineyards. Spiders were collected from grapevine plants, using two collecting methods (foliage beating and direct collection). Plants with and without cardboard bands (N = 30) were sampled in three different phenological stages of the vineyard (veraison, maturity and postharvest). Overall, we collected 904 spiders belonging to 35 species. We found that spider abundance and species richness significantly increased with cardboard bands. In addition, we identified particular species that prefer cardboard bands to build their shelters. Results suggest that cost-effective habitat manipulation can increase spider abundance in vineyards, which implies higher biodiversity conservation value and potential for improving biological control.

“…But on the other hand, agricultural landscapes harbour a great number of arthropods that contribute to the high local biodiversity recorded over many centuries in temperate regions. Many of these arthropods are thought to provide ecosystem services (Isaacs et al, 2009;Salman et al, 2019). Therefore, sustainable land use that maintains the biodiversity associated with native plants tends to be higher than that associated with non-native plants (Isaacs et al, 2009), the extent of the potential effect of novel nonnative energy plants such as cup plant and Virginia mallow should be of special interest to policy makers.…”

http://www.eje.cz or restores biodiversity and maximize ecosystem services should be implemented.In addition to the challenge to conserve biodiversity and produce food, farmland is increasingly needed to produce renewable energy. To reduce greenhouse gas emissions the German Renewable Energy Sources Act (EEG) fostered bioenergy production. Consequently, the number of biogas plants in Germany increased from about 850 in 2000 to 9,311 in 2017 (Yang et al., 2021). The associated, increase in cultivation of maize (Zea mais L., Poaceae) for the biogas plants and resultant loss of set aside land and fi eld borders due to increasing land costs and management intensity lead to a controversy over the environmental and socio-economic effects of this policy (Dauber et al., 2010;Gevers et al., 2011;Robertson et al., 2012).When compared to oilseed rape, potatoes, or even cereals, maize requires fewer pesticide treatments per year (Roßberg, 2016), because yields are less dependent on fungal diseases and insect pests. Yet, insect diversity in maize
