Abstract. Abidin Z, Leksono AS, Yanuwiadi B, Purnomo M. 2020. Refugia effect toward arthropods in an organic paddy field in Malang District, East Java, Indonesia. Biodiversitas 21: 1415-1421. This study aims to determine the abundance, community structure, and diversity of arthropod visitors of refugia in organic paddy fields in the Malang District of East Java, Indonesia. This research was conducted in 2019 from February to June and covered the stages from planting to harvest. The paddy fields were divided into 12 plots consisting of six refugia plots and six control plots. Sampling was carried out in two five-day phases, specifically in the vegetative phase (February) and the generative phase (June) of paddy plants. The results showed that 28.184 species consisting of nine orders and 40 families were observed. The abundance of common predator families, such as the Aleyrodidae, Formicidae, Libellulidae, and Tetragnatidae, in organic paddy. The average arthropod taxa richness in the refugia was 20.59 ± 12.24 species, while in the control it was 13.16 ± 8.95 species. Statistical analysis showed that the difference was significant (p < 0.05). The average arthropod diversity in the refugia was 2.39 ± 0.78 species, while in control was 2.35 ± 0.15 species. In conclusion, the population of arthropods was the highest in the refugia. Therefore, organic paddy surrounded by refugia with wild plants was the most appropriate habitat and niche for predatory arthropods.

Abstract. Leksono AS, Yanuwiadi B, Khotimah A, Zairina A. 2021. Grasshopper diversity in several agricultural areas and savannas in Dompu, Sumbawa Island, Indonesia. Biodiversitas 23: 75-80. In Sumbawa Island, the conversion of forests and savannahs into agricultural land has increased rapidly since 2010. This research aims to compare grasshopper species' abundance, richness, and diversity between several farmland and savannas in Dompu, Sumbawa Island. It was conducted at ten locations in Dompu, Sumbawa Island, and included an ecotone, two post-harvested rice farms, two post-harvested corn farms, a mixed farm, a vegetable farm, and three savannas. Furthermore, samples were taken four times from four plots at each location in the post-harvest period from August to September 2021. Grasshopper sampling was carried out using the sweeping method with an insect net with each plot size of 2 x 10 m2. A total of 2264 individual grasshoppers belonging to 30 species and four families were collected from all research sites. The dominant species were Alloteratura sp., Trilophidia annulata, Atractomorpha crenulata, Phlaeoba fumosa, Oxya japonica and, Phlaeoba infumata. The greatest grasshopper species richness and diversity were found in post-harvest rice farms, while the lowest was in the vegetable farm, and most of these species are considered pests. This research shows that the composition of grasshoppers on agricultural land is very similar to that of the adjacent savannah. Hence, monitoring and controlling their presence is necessary by paying attention to savannas as refuge land.
