Abstract. Herlinda S, Karenina T, Irsan C, Pujiastuti Y. 2019. Arthropods inhabiting flowering non-crop plants and adaptive vegetables planted around paddy fields of freshwater swamps of South Sumatra, Indonesia. Biodiversitas 20: 3328-3339. Local farmers in freshwater swamps of South Sumatra traditionally plant adaptive flowering vegetables surrounding paddy fields and let wild flowering plants or non-crop plants grow on the embankment. This research aimed to determine the species of non-crop plants and adaptive vegetables surrounding the freshwater swamp paddy fields as habitats and niches of arthropods. This study used four species of flowering non-crop plants (Zinnia sp., Tagetes erecta, Cosmos caudatus, Sesamum indicum) and four species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, Luffa acutangula) planted around the paddy fields. While the arthropods were collected using sweep nets. There were 24 species of predatory arthropods, three species of parasitoids, 17 species of herbivores, and nine species of neutral insects found in the non-crop plants and vegetables. The non-crop plant and vegetable species that were the most chosen by the predatory arthropods were Zinnia sp. and M. charantia, respectively. Species of the non-crop plants and vegetables chosen by the parasitoids were T. erecta and M. charantia, respectively. Those non-crop plants and adaptive vegetables were also the most chosen plants by the predatory arthropods for their habitats and niches. Therefore, for the conservation of natural enemies, it is better to use Zinnia sp., T. erecta, and M. charantia.

Abstract. Herlinda S, Prabawati G, Pujiastuti Y, Susilawati, Karenia T, Hasbi, Irsan C. 2020. Herbivore insects and predatory arthropods in freshwater swamp rice field in South Sumatra, Indonesia sprayed with bioinsecticides of entomopathogenic fungi and abamectin. Biodiversitas 21: 3755-3768. Herbivore insect population and predatory arthropods in rice field may be effected by the application entomopathogenic fungi or synthetic insecticide. The objective of this research was to analyze individual quantity of herbivore insects and predatory arthropod inhabiting freshwater swamp rice fields treated with bioinsecticides and abamectin (commercial insecticide). This research was conducted in the freshwater swamp rice field located in Village Pelabuhan Dalam, Sub District Pemulutan, District Ogan Ilir, and South Sumatra. The experiment was arranged in a Completely Randomized Block Design consisted of four plots of treatment. The research used the bioinsecticides made from entomopathogenic fungi (Beauveria bassiana, Metarhizium anisopliae, and Cordyceps military), and abamectin. Sampling to collect arthropods inhabiting rice canopy was also conducted using an entomological net in the study locations. This research found 12 families of herbivore insects with 22 species dominated by Nilaparvata lugens and Leptocorisa acuta and 32 species of spider belonged to eight families dominated by Tetragnatha virescens and Oxyopes matiensis. The species diversity of spider was higher in the plots of the bioinsecticide compared to that of the abamectin. Predatory insects found belonged to 14 species belonged to eight families dominated by species of Ophionea nigrofasciata, Verania discolor, and Paedorus fuscipe. The abundance of predatory insects in plots sprayed with the bioinsecticides was higher compared to that of the abamectin plot. The abundance and species diversity of predatory arthropod sprayed with bioinsecticide of B. bassiana, M. anisopliae, and C. militaris did not decrease, while the population of herbivore insect tended to decrease.

Abstract. Anggraini E, Anisa WN, Herlinda S, Irsan C, Suparman S, Suwandi S, Harun MU, Gunawan B. 2021. Phytophagous insects and predatory arthropods in soybean and zinnia. Biodiversitas 22: 1405-1414. In Indonesia, soybean is the third most important commodity after rice and corn. Cultivation technique such as planting hedgerows was expected to attract and retain natural enemies of pest predators. This study was conducted to determine the phytophagous insects and predatory arthropods species in soybean (Glycine max L.) and zinnia (Zinnia sp., hybrids) plants as refugia. This study utilized three methods i.e., visual observation, pitfall trap, net-trap in both soybean and zinnia planting areas. All collected insects were carried to the laboratory for observation and identification using insect determination key book. Insect identification was based on their morphological characteristics. The results study showed that phytophagous and predatory arthropods were found in both soybean and zinnia plantations in Agro-Techno Center (ATC), Sriwijaya University, Indonesia. There were 11 species of phytophagous and 5 species of entomophagous insects identified at soybean cultivation. Meanwhile, 5 species of phytophagous and 9 species of predatory arthropods including five spider species found, namely Pardosa distincta, Oxyopes javanus, Lycosa pseudomonas, Pardosa sp. and Drapetisca socialis at zinnia cultivation area. However, chi-square analysis (at alpha 0.05), confirmed that there was no significant difference between predatory arthropods in soybean and Zinnia the results indicate that soybean is might be suitable to be planted as refugia for predatory arthropods.

Abstract. Herlinda S, Tricahyati T, Irsan C, Karenina T, Hasbi, Suparman, Lakitan B, Anggraini E, Arsi. 2021. Arboreal arthropod assemblages in chili pepper with different mulches and pest managements in freshwater swamps of South Sumatra, Indonesia. Biodiversitas 22: 3057-3066. In the center of freshwater swamps in South Sumatra, three different chili cultivation practices are generally found, namely differences in mulch and pest management that can affect arthropod assemblages. The effect of mulches and pest management on arboreal arthropod assemblages specific to chili production centers in the freshwater swamps of South Sumatra has never been investigated. This study aimed to observe arboreal arthropod assemblages in chili with different mulches and pest management. Arboreal arthropods were sampled using sweep nets in three locations with plots treated with leaf litter mulch and bioinsecticide, plastic mulch and synthetic insecticide, and weedy plot without mulch with synthetic insecticide. The species number of arboreal arthropods found was 28 species of Arachnids and 23 species of Insects, and consisting of 6 families of the Arachnids and 25 families of Insects. The abundance of arboreal arthropods was 65.60 individuals/5 nets per observation. In the chili field without mulch but with the insecticide, the species biodiversity and abundance of arboreal predatory arthropods were the highest. In contrast, in the chili field, that applied with synthetic insecticides and plastic mulch, the abundance of arboreal predatory arthropods was the lowest. The herbivorous insect populations in chili with plastic mulch and synthetic insecticides and the chili with the leaf litter mulch were higher than those in the chili without mulch. In the chili with the leaf litter mulch and bioinsecticide, the species number and abundance of the spiders were the highest compared to the other chili fields. The weedy chili field without mulch and chili with the leaf litter mulch has proved ideal habitats for the arboreal predatory arthropods.
