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.

维持农业系统中的生物多样性至关重要，因为它在提供生态系统服务中发挥着关键作用。但是，它正在以前所未有的速度下降。几种方法可有助于增加农业生态系统中的物种多样性，包括使用人工微生境。最近，主要在欧洲和北美进行了针对葡萄园中生物多样性的研究，但在南美却很少。在这项研究中，我们调查使用瓦楞纸板带是否引入环境变异性和栖息地复杂性，增强葡萄园中蜘蛛的丰度和多样性。使用两种收集方法（叶拍打和直接收集）从葡萄植物中收集蜘蛛。在葡萄园的三个不同物候阶段（普通，成熟和收获后）对有纸板带和无纸板带（N = 30）的植物进行采样。总体而言，我们收集了904种属于35种蜘蛛的蜘蛛。我们发现，随着纸板带的增加，蜘蛛的丰度和物种丰富度显着增加。此外，我们确定了喜欢使用纸板带建造庇护所的特定物种。结果表明，具有成本效益的栖息地操纵可以增加葡萄园中蜘蛛的丰度，这意味着更高的生物多样性保护价值和改善生物控制的潜力。我们发现了喜欢用纸板带建造庇护所的特定物种。结果表明，具有成本效益的栖息地操纵可以增加葡萄园中蜘蛛的丰度，这意味着更高的生物多样性保护价值和改善生物控制的潜力。我们发现了喜欢用纸板带建造庇护所的特定物种。结果表明，具有成本效益的栖息地操纵可以增加葡萄园中蜘蛛的丰度，这意味着更高的生物多样性保护价值和改善生物控制的潜力。
