Abstract. Ihsan M, Puspitarini RD, Afandhi A, Fernando I. 2021. Abundance and diversity of edaphic mites (Arachnida, Acari) under different forest management systems in Indonesia. Biodiversitas 22: 3685-3692. Edaphic mites play crucial roles in maintaining ecosystem services that are essential to human needs. However, the conversion of natural habitats followed by agricultural intensification may adversely affect edaphic mites. The objective of this study was to investigate the influence of different management systems on edaphic mite abundance, richness, and diversity in tropical rain forests in Indonesia. There were five forest management systems, which were as follows: secondary forest, production forest (pine monoculture), and three agroforestry systems (pine + coffee, mahogany + coffee, and mahogany + new cocoyam). We established a transect containing five research plots for each forest management system. Litter and soil from each plot were collected from December to March 2021. Temperature, relative humidity, and pH of litter and soil, as well as litter thickness, were measured. We found that edaphic mite abundance, richness, and diversity in the secondary forest were similar to managed forests. However, the aforementioned variables were significantly higher in “pine” systems than in “mahogany” systems. Our analysis evidenced positive correlations between litter thickness and edaphic mite abundance, richness, and diversity. Our findings may assist in selecting the appropriate forest management systems to rationalize the conversion of secondary forests to production forests and agroforestry.

Abstract. Puspitarini RD, Purwantoro A, Pradifta VDA, Muhammad FN, Fernando I. 2024. Abundance of arthropod pests and their natural enemies on cassava fields implementing different agroecosystem management. Biodiversitas 25: 2901-2907. Arthropod pests pose significant challenges to cassava (Manihot esculenta Crantz) cultivation, with detrimental effects on yield and crop quality. Agroecosystem management plays a crucial role in shaping the populations of pests and their natural enemies. Therefore, understanding and implementing appropriate management practices are essential for developing integrated pest management approaches that are effective and environmentally friendly. Our study examined herbivorous and predatory arthropod abundance across six cassava plantations with varying management practices. Field characteristics were examined to elucidate the factors contributing to differences in arthropod assemblages observed among the fields. We used Analysis of Variance (ANOVA) to assess the differences in arthropod abundance across the plantations. Additionally, arthropod assemblage was analyzed using analysis of similarity based on the Bray-Curtis Index, with differences visualized using non-metric multidimensional scaling (NMDS) plots. The high abundance of herbivorous arthropods in certain fields appeared linked to narrow plant spacing, which might facilitate pest dispersal. Furthermore, complete weed removal and the absence of organic fertilizer application, such as manure, could reduce predatory arthropod populations. Additionally, fields situated at lower altitudes demonstrated increased susceptibility to pest outbreaks. Therefore, strategic agroecosystem management is imperative, incorporating practices to mitigate pest population growth while conserving predatory arthropods. Comprehending the interplay between management practices and arthropod dynamics is crucial for developing sustainable pest management strategies in cassava cultivation.

Abstract. Fernando I, Muhammad FN, Furqoni R, Mario MB, Puspitarini RD, Trianti I, Syib’li MA, Rizali A. 2024. Local and landscape effects on the abundance and diversity of soil arthropods in citrus orchards of Malang and Batu, East Java, Indonesia. Biodiversitas 25: 3920-3927. Soil arthropods are crucial for sustaining the balance and function of agroecosystems. This study aimed to assess the diversity and abundance of detritivorous and predatory soil arthropods across various citrus orchards that differ in agroecosystem management practices and landscape composition. The study was conducted in nine citrus orchards from November 2023 to January 2024, with soil arthropod samples collected using Berlese funnels. Analysis of Variance (ANOVA) was used to evaluate the effects of management practices (local effects) on soil arthropod diversity and abundance, while Generalized Linear Model (GLM) analysis was employed to assess the effects of landscape composition (landscape effects) on soil arthropod diversity and abundance. Meanwhile, Analysis of Similarity (ANOSIM) based on the Bray-Curtis index was used to evaluate differences in soil arthropod composition. A total of 1,562 individuals were collected, representing 16 families, 11 orders, and 3 classes. Among the predatory groups, the most abundant family was Laelapidae, while Entomobryidae was the most dominant among detritivores. The diversity of both predatory and detritivorous arthropods was not influenced by variations in management practices. However, the abundance and composition of predatory arthropods were influenced by the frequency of organic fertilizer application, while detritivores were affected by weeding treatments. At the landscape scale, predator abundance positively correlated with the number of natural habitat patches and the area of citrus orchards. In contrast, detritivores were not influenced by landscape variables. This study highlights the critical roles of land management practices and landscape composition in shaping the abundance and diversity of soil arthropods.
