“…These species can grow well on the soil surface, indicating they are not true epiphytes. The results confirmed the findings of Suzanti et al (2016), which found that true epiphytes were uncommon in an oil palm plantation. The species of pteridophytes in the eastern region were more diverse than those in the west, as seen in Table 2.…”

“…Nurdiansyah et al (2016) suggested that maintaining plant diversity and fostering weedy strips could be effective for the biological control of pests and disease. Meanwhile, vascular epiphytes may help support insect biodiversity (Suzanti et al 2016). It also increases understory vegetation, mitigates the adverse effects of forest resources, and prevents the loss of diversity (Ashton-Butt et al 2018;Nájera and Simonetti 2010).…”

“…Material deposit is a medium for most epiphytic plants to grow on oil palm trunks. Vascular epiphytes are commonly attached to the oil palm stem (Suzanti et al 2016), where microfauna, mesofauna, macrofauna, and different types of amoeba, are also observed (Potapov et al 2020). Each material deposits microbiome will differ from terrestrial soils (Eskov et al 2021).…”

Abstract. Pradiko I, Farrasati R, Rahutomo S, Sapalina F, Pane RDP, Hidayat F, Ginting EN. 2022. The physical, chemical, and biological characteristics of microhabitats inside oil palm trunk axils in North Sumatra, Indonesia. Biodiversitas 23: 3793-3807. Above-ground ecosystems (AGE) components in oil palm plantations consist of epiphytic plants and fauna in microhabitat within the axil of pruned fronds. This research aimed to identify the characteristics of microhabitat, including microclimate profile, physical and chemical properties of the material deposit, epiphyte abundance, and microbe population. The study sites were located in the eastern and western regions of North Sumatra. Furthermore, vertical observations were taken on oil palm trunks at the height of 20, 100, 150, 200, and 300 cm. The study indicated that the microclimate, nutrients content, physical properties of the material deposit, and bacterial populations in the trunk axils of oil palm in the eastern differed from the western region. There was no obvious pattern in the microclimate profile for individual oil palms. However, there was a change in N, C-organic, and C/N ratios with the increasing height of microhabitat sites. In terms of abundance, Nephrolepis bisserata and Vittaria ensiformis epiphytes were more dominant in the upper and bottom trunk, respectively. The microhabitat at the bottom trunk had a denser bacterial population, negatively correlated with N, C-organic, C/N ratio, Mg, and pH.

“…The percentage of pest attacks in intercropping cropping patterns is lower compared to monoculture cropping patterns. This is thought to be because the intercropping pattern, apart from providing nectar from flowers needed by parasitoid and predatory insects (Saputra et al, 2023;Allifah, 2013;Kurniawati & Martono, 2015;Suswati et al, 2021;Azwana & Sihotang, 2023), also contains repellent compounds for insect pests (Nurdiansyah et al, 2016;Suzanti et al, 2016). The use of intercropping increases plant diversity in the field which can suppress pest attacks and increase the performance of natural enemies (Nirmayanti et al, 2015).…”

Coffee is one of the leading commodities in the plantation subsector in North Sumatra which has good market opportunities both domestically and abroad. Especially in the Lake Toba area, apart from the PBKo pest, it turns out that attacks by the coffee leaf sucking pest Helopeltis sp. are also felt to be very important by farmers, because the presence of Helopeltis sp. This causes the coffee leaf shoots to develop brown spots, curl and eventually dry out and die (die back). The aim of the research was to study the symptoms of attacks and the intensity of Helopeltis sp. attacks on Arabica coffee plants in the Lake Toba area, North Tapanuli Regency. This research was carried out on people's coffee plantations in North Tapanuli Regency at an altitude of 1,300 meters above sea level, from February to June 2023. On the Sigarar Utang variety Arabica coffee plantation with monoculture and polyculture planting patterns. The sample plants were determined to be 10% of the total plants at each observation location. Sampling of plant samples is determined using a zig zag line. The parameters observed were the intensity of attacks and the percentage of pest attacks. The results obtained by Helopeltis sp. sucking shoot pests have been known to attack coffee plants in North Tapanuli Regency with symptoms of attack. At the start of the attack, leaf spots are visible, brown, curly and eventually dry out, die back, then grow rosettes, namely shoots, new ones that are shortened tightly and do not develop. The intensity of attacks by Helopeltis sp. on smallholder coffee plantations in North Tapanuli Regency is quite varied, from light to heavy attacks with the intensity of shoot attacks ranging from 15.67% to 57.80%. Monoculture coffee plantations with protective plants, but no pruning, are locations with Helopeltis sp. attack levels in the heavy category with shoot attack intensity reaching 56.66%. The intercropping coffee plant cultivation system (polyculture) had a significant influence on the low intensity of Helopeltis sp. attacks, where tcount (8.921) > ttable (2.306).

Oil palm plantations are typically managed in a monoculture system over large areas. This system contributes to biodiversity loss and promotes pest outbreaks by reducing natural enemies. However, ecosystem functions in oil palm plantations vary spatially and temporally and can still support biodiversity under certain conditions. We conducted a study on the species richness, abundance and species composition of natural enemies in oil palm plantations and investigated the factors influencing natural enemy communities in oil palm plantations at both local and landscape scales. We selected 12 sites in an oil palm plantation in Central Borneo, Indonesia, which were grouped into 4 sub‐areas based on the presence of natural habitats, which varied in local and landscape characteristics. Arthropods were sampled using canopy knockdown fogging with a pyrethroid insecticide. Different taxa of natural enemies responded differently to changes in habitat characteristics within oil palm plantations. Species richness of spiders was not affected by either local or landscape scale, but their species composition was affected by oil palm tree age (local scale) and the total edge of dominant oil palm tree age (landscape scale). Ant species richness was influenced by the class area of natural habitat (landscape scale), whereas their species composition was not influenced by either local or landscape scale. On the other hand, species richness of parasitoid wasps was influenced by light intensity (local scale) and the variation of oil palm tree age within a landscape (landscape scale). However, their species composition was only affected by light intensity. The results suggest that oil palm management practices need to consider both local and landscape scales to maintain biodiversity and biological control and to achieve sustainable management of oil palm plantations.
