Complex agroforestry systems are suggested as a possible solution to reduce the effects of deforestation in the tropics while enhancing the livelihoods of local human populations. Coffee (Coffea spp.) is one of the most important commodity crops in the world that can easily be cultivated in complex agroforestry systems. Coffee agroforestry systems usually sustain higher biodiversity levels than sun-exposed fields while keeping similar levels of productivity considering the several benefits of growing coffee under a complex system. We aim to explore the richness and abundance of invertebrates in coffee home gardens in West Java, Indonesia by comparing 14 sun-exposed and 14 shade-grown gardens. We collected data in March/April 2019 via pitfall traps, pan traps, and beating tray in each field. We ran generalised linear models to assess whether the number of species and the number of individuals of insects differed between sun-exposed vs. shade-grown coffee gardens, and tested associations between main taxa. Overall, there was no difference in the richness (sun-exposed: 19.86 ± SE1.19; shade-grown: 19.71 ± SE1.19; Z-value = 0.12, value = 0.904) and abundance (sun-exposed: 141.93 ± SE 3.18; shade-grown: 139.93 ± SE3.16; Z-value = 0.35, value = 0.706) of invertebrates in coffee gardens, although taxa specific differences were present. Sun-exposed fields had a higher abundance of invertebrates considered as pests (Blattodea: Rhinotermitidae, Ectobiidae; Coleoptera: Scarabaeidae, Lycidae and Tenebrionidae; Diptera: Anisolabididae, Drosophilidae and Sarcophagidae). Camponotus spp. were the most dominant ants in shade-grown gardens while Dolichoderus spp. and Myrmicaria spp. were more abundant in sun-exposed gardens. Despite the fact that sun-exposed coffee fields registered higher abundance of invertebrate pests than shade-grown coffee fields, the richness of invertebrates did not substantially vary between sun-exposed and shade-grown coffee, suggesting that the matrix of gardens offers advanced ecosystem services. It is important to keep the complexity of agroforestry systems that provide key habitats for biodiversity.

印度尼西亚阴凉种植与阳光照射的咖啡家庭花园中无脊椎动物的丰富程度

建议将复杂的农林业系统作为一种可能的解决方案,以减少热带地区森林砍伐的影响,同时提高当地人口的生计。咖啡(咖啡spp.) 是世界上最重要的商品作物之一,可以在复杂的农林业系统中轻松种植。考虑到在复杂系统下种植咖啡的诸多好处,咖啡农林业系统通常比暴露在阳光下的田地维持更高的生物多样性水平,同时保持相似的生产力水平。我们的目标是通过比较 14 个阳光照射的花园和 14 个阴凉的花园,探索印度尼西亚西爪哇咖啡家庭花园中无脊椎动物的丰富程度。我们在 2019 年 3 月 / 4 月通过每个田地的陷阱陷阱、平底陷阱和打浆盘收集了数据。我们运行了广义线性模型来评估昆虫的物种数量和个体数量在阳光照射和阴凉种植的咖啡园之间是否存在差异,并测试了主要分类群之间的关联。总体,值 = 0.904)和咖啡园中无脊椎动物的丰度(日晒:141.93 ± SE 3.18;阴凉处:139.93 ± SE3.16;Z 值 = 0.35,值 = 0.706),尽管存在分类群的特定差异. 暴露在阳光下的田地中被认为是害虫的无脊椎动物的丰度较高(Blattodea:Rhinotermitidae、Ectobiidae;鞘翅目:Scarabaeidae、Lycidae 和 Tenebrionidae;双翅目:Anisolabididae、Drosophilidae 和 Sarcophagidae)。Camponotus spp。是遮荫花园中最主要的蚂蚁,而Dolichoderus spp。和桃金娘spp. 在阳光照射的花园中更为丰富。尽管暴露在阳光下的咖啡田比在阴凉处种植的咖啡田记录了更多的无脊椎动物害虫,但在阳光暴露和阴凉处种植的咖啡之间,无脊椎动物的丰富度并没有显着差异,这表明花园矩阵提供了先进的生态系统服务. 保持为生物多样性提供关键栖息地的农林业系统的复杂性非常重要。
