Bat populations are threatened in many regions of the world, partly due to the loss of foraging and commuting habitats in farmland and declines in insect prey populations caused by agricultural intensification. Given that bats play an important role as bioindicators and in suppressing crop pests, it is crucial to mitigate negative impacts that arise from these threats. In this study we evaluated the richness, quantified at family level, and abundance of bat prey insects in organic vineyards surrounded by three types of adjacent habitat: urban/semi-urban areas, exotic tree plantations, and remnants of native vegetation. The relationship between the abundance of prey and the foraging activity of bats in the vineyards was also examined. Insects were sampled using ultraviolet light traps, located both inside and at the edge of the vineyards. Bat activity was monitored at each site using acoustic recorders. The insect richness was unaffected by the type of adjacent habitat and did not differ between the edge and the interior of the vineyards. In contrast, insect abundance was significantly influenced by the type of adjacent habitat. Vineyards adjacent to native vegetation and exotic tree plantations showed the highest abundances for most insect orders present in the bat diet compared to urban areas. Bat activity was significantly correlated with the abundance of Coleoptera and Lepidoptera, with mixed effects between bat species (negative for Tadarida brasiliensis, positive for Lasiurus varius, Lasiurus villosissimus and Myotis chiloensis). Crop edges adjacent to native vegetation provides important foraging habitat for bats and should therefore be considered in agricultural management. Locating vineyards close to these habitats may promote bat conservation via increased prey insects and may also benefit winegrowers through the ecosystem services provided by insectivorous bats in this crop.

蝙蝠种群在世界许多地区都受到威胁，部分原因是农田的觅食和通勤栖息地的丧失以及农业集约化导致昆虫猎物种群的减少。鉴于蝙蝠作为生物指标和抑制作物病虫害发挥着重要作用，减轻这些威胁产生的负面影响至关重要。在这项研究中，我们评估了被三类相邻栖息地包围的有机葡萄园中蝙蝠捕食昆虫的丰富度、家庭层面的量化和丰度：城市/半城市地区、异国情调的树木种植园和原生植被的残余。葡萄园中猎物的丰富性与蝙蝠的觅食活动之间的关系也得到了研究。使用位于葡萄园内部和边缘的紫外线陷阱对昆虫进行采样。蝙蝠的活动在每个地点使用录音机进行监测。昆虫丰富度不受相邻栖息地类型的影响，并且在葡萄园的边缘和内部之间没有差异。相比之下，昆虫丰度受相邻栖息地类型的显着影响。与城市地区相比，与本地植被和外来树木种植园相邻的葡萄园显示蝙蝠饮食中存在的大多数昆虫目的丰度最高。蝙蝠的活动与鞘翅目和鳞翅目的丰度显着相关，蝙蝠物种之间存在混合效应（负 昆虫丰度受相邻栖息地类型的显着影响。与城市地区相比，与本地植被和外来树木种植园相邻的葡萄园显示蝙蝠饮食中存在的大多数昆虫目的丰度最高。蝙蝠的活动与鞘翅目和鳞翅目的丰度显着相关，蝙蝠物种之间存在混合效应（负 昆虫丰度受相邻栖息地类型的显着影响。与城市地区相比，与本地植被和外来树木种植园相邻的葡萄园显示蝙蝠饮食中存在的大多数昆虫目的丰度最高。蝙蝠的活动与鞘翅目和鳞翅目的丰度显着相关，蝙蝠物种之间存在混合效应（负Tadarida brasiliensis，Lasiurus varius、Lasiurus villosissimus和Myotis chiloensis阳性）。邻近原生植被的作物边缘为蝙蝠提供了重要的觅食栖息地，因此应在农业管理中予以考虑。将葡萄园靠近这些栖息地可以通过增加捕食昆虫来促进蝙蝠保护，还可以通过这种作物中食虫蝙蝠提供的生态系统服务使葡萄种植者受益。
