The diversity of arthropod communities is often used as a bioindicator of environmental changes, specifically in coffee farms with various management systems. Significant impacts of the environmental changes lead to alterations in the community structure and function of arthropods. The aim of this research was to determine the diversity and ecological roles of insect and arachnids in arabica coffee plantations in Bandung Regency. Sampling was conducted on five plots measuring 100 m2 each, with a separating distance of 50 m, in coffee farms located in Legok Nyenang Village, Bandung Regency. This was performed five times per weekly intervals using sweep nets, yellow tray traps, and beating sheets. Subsequently, collected samples were identified based on morphological characters at the Pest Laboratory, Faculty of Agriculture, Padjadjaran University. A total of 269 insects species (11 orders and 98 families, total 669 individuals) and 23 species of Arachnida (one order and 13 families, total 44 individuals) were found, The most abundance of natural enemies were the parasitoid, Megacampsomeris prismatica (Hymenoptera: Scoliidae) and the predator, Tetragnatha sp. (Araneae: Tetragnathidae). Meanwhile, the ecological function of the group with the lowest number was pollinators (Hymenoptera: Apidae). Although the diversity of insects and arachnids species found in coffee farms was high (H' = 5.10), the evenness and dominance index were relatively low. These results showed the potential of coffee plantations as ecosystems for conserving predatory arthropods biodiversity. Consequently, coffee cultivation practices and pest management strategies must prioritize the protection of beneficial insects such as natural enemies and pollinators.

Thrips is an important worldwide cause of severe damage to various host plants, especially chrysanthemums. Current management still relies on synthetic insecticides to control thrips. However, these pesticides harm the environment and promote thrips resistance. The study aimed to compare integrated pest management (IPM) and farmer’s standard practices to control Thrips parvispinus on two chrysanthemum varieties and calculate the cost-benefit ratio of both pest control practices. Two chrysanthemum cultivars were planted in plastic houses to compare IPM and farmer’s standard practices. The observed variables included thrips density, attack and damage rates, cut flower yield, and natural enemies abundance. Data were analyzed using ANOVA, and Tukey's HSD test identified significant differences at a 5% level. The results showed that the population of T. parvispinus nymphs was higher (78%) than adults. The highest adult thrips population emerges when chrysanthemums achieve the flowering phases. This study reveals that the control effects of IPM were not different from farmer’s standard practices. A holistic approach integrating several management strategies successfully controlled the thrips population while producing high-quality crops with minimal aesthetic damage. The IPM strategy against thrips showed a competitive cost and reduced synthetic insecticide applications without decreasing the quality and productivity of chrysanthemums.

The most economically important invasive thrips species, known for causing serious damage to various crops through feeding and virus transmission, was recorded in the cut flower production center of West Java Province, Indonesia. Thrips specimens were collected from chrysanthemum plastic houses using sweep nets, beating trays, yellow pan traps, and hand vacuums. Based on morphological characteristics, the specimens were identified as Frankliniella occidentalis Pergande 1895 (Thysanoptera: Thripidae). Infestation levels in chrysanthemum ranged from 9 to 15 individuals per plastic house. This is the first confirmed report of F. occidentalis infesting chrysanthemums in Indonesia, as the species has not been previously recorded in the country. It can be distinguished from other thrips species by its unique morphological traits, including comb-like setae on the eighth abdominal tergite and distinctive chaetotaxy patterns on the head and pronotum.
