Keberhasilan budi daya tanaman kacang-kacangan dipengaruhi oleh keberadaan Arthropoda yang berperan sebagai polinator, dekomposer, parasitoid, dan bioindikator. Tujuan penelitian ini untuk menentukan keanekaragaman Arthropoda pada lahan pertanian kacang-kacangan di Kabupaten Kupang. Penelitian ini bersifat deskriptif kuantitatif yang telah dilaksanakan di tiga lokasi, yaitu lahan kacang tanah, lahan kacang panjang, dan lahan kacang hijau. Pengambilan sampel Arthropoda menggunakan pitfall trap, insect net, dan hand sorting. Hasil penelitian ditemukan keanekaragaman Arthropoda yang bervariasi di tiga lahan pertanian kacang. Pada lahan pertanian kacang tanah ditemukan 31 spesies, 15 famili, 9 ordo, 2 kelas, dengan total individu 115. Pada lahan pertanian kacang panjang ditemukan 17 spesies, 11 famili, 7 ordo, 2 kelas, dengan total individu 53. Pada lahan pertanian kacang hijau ditemukan 30 spesies, 20 famili, 9 ordo, 3 kelas, dengan total individu 108. Indeks keanekaragaman tertinggi terdapat pada lahan pertanian kacang hijau sebesar 3.19, diikuti lahan kacang tanah sebesar 2.83, dan lahan kacang panjang sebesar 2.43. Nilai indeks kekayaan jenis tertinggi terdapat pada lahan kacang tanah sebesar 6.32 diikuti lahan kacang hijau sebesar 6.19, dan terendah lahan kacang panjang sebesar 4.03. Tidak ada jenis Arthropoda yang mendominasi di ketiga lahan pertanian kacang dengan kemerataan jenis tergolong merata penyebarannya. Kesamaan Jaccard antar habitat kacang menunjukkan nilai lebih kecil dari 50%, artinya tingkat kesamaan famili Arthropoda yang ditemukan di ketiga habitat kacang tergolong rendah.Tingkat kesamaan yang rendah dapat disebabkan oleh aplikasi pestisida khususnya pada lahan kacang panjang dan kacang hijau. Selanjutnya, faktor abiotik memberikan pengaruh yang signifikan terhadap keanekaragaman arthropoda.

Abstract. Sembiring M, Munawaroh H, Mukhlis, Hidayat B, Sabrina T. 2021. Soil macrofauna diversity in andisol after eight years of Mount Sinabung eruption in Sumatra, Indonesia. Biodiversitas 22: 3024-3030. The eruption of Mount Sinabung resulted in volcanic ash covering the soil of various thicknesses. That will affect the population and diversity of macrofauna in it. This research aimed to determine the Andisol soil macrofauna in Karo District with various thicknesses of volcanic ash covering from Mount Sinabung. This research was conducted in May 2019. Plots were placed in four locations, Location I: processed land (0 cm), Location II: Land covered by thin ash (?2 cm), Location III: Land covered by medium ash (2-5 cm), Location IV: Land covered by thick ash (?5 cm). Sampling was conducted by using the Pitfall trap, Monolith squared, and Hand sorting methods. The research results indicated that the thicker the volcanic ash covering the soil surface, it would reduce soil moisture, soil water content, organic C, and soil pH, but on the other hand, increase the soil temperature. A total of 20 species were able to live on the Andisols affected by the eruption of Mount Sinabung.

Changed soil conditions will result in the changed population and diversity in the soil. The eruption of Sinabung Mount caused the surface of the soil covered with volcanic ash with various thicknesses. This research was to study a description of macrofaunal communities at different thicknesses of Sinabung volcanic ash on andisol soil in Karo Regency. The experiment was conducted in May 2017. The experiment plot was located at four locations, location I was not covered by ash (0 cm), location II was covered with thin ash (≤2 cm), location III was covered with medium ash (2-8 cm), location IV was covered with thick ash (≥8 cm) using the transect sampling method. Samples was collected by using the Pitfall Trap, Monolith quadrant, and the Hand Sorting method. Macrofaunal communities found 3 phyla, 6 classes, 11 orders, 17 families, and 18 species at location I. Macrofaunal communities found 3 phyla, 7 classes, 11 orders, 16 families, and 17 species at location II. Macrofaunal communities found 2 phyla, 3 classes, 7 orders, 9 families, and 9 species at location III. Macrofaunal communities found 1 phylum, 2 classes, 5 orders, 7 families, and 7 species at location IV.

AbstractThe effects on carabids of natural, fescue, and rye sod types and of tillage were investigated in a pest management apple orchard. Carabids were sampled before and after the treatments by pitfall trapping and by two types of soil sampling. There were no significant effects of sod type on pitfall trap catches; however the abundance of all common species in soil samples was significantly affected by sod types. Usually in soil samples carabids were most abundant in natural sod and least abundant in tilled plots; numbers were intermediate in fescue and rye. Sod type did not affect structure or diversity of the carabid fauna.

Size Dimorphism

Allocosa brasiliensis (Petrunkevitch, 1910) is a nocturnal wolf spider inhabitant of coastal dunes. Pitfall-trap data suggested the occurrence of two sympatric and synchronic morphs, with differences in adult size and abdominal design (minor and major morphs). Previous studies performed with the major morph of A. brasiliensis, postulated courtship-role and sexual size dimorphism reversal for this spider. In the present study, we compare data on development and morphology and test reproductive isolation between morphs of A. brasiliensis, with the hypotheses that the two morphs are reproductively isolated and both show courtship-role reversal. As had been reported for the major morph of A. brasiliensis, the minor-morph females approached the burrows of minor-morph males, entered, initiated courtship, and after copulation, males closed their burrows with female cooperation from the inside. Females did not court or copulate with males belonging to the other morph and, in two cases, major-morph females cannibalised minor-morph males. Morphometrical and developmental data showed differences between morphs. The occurrence of copulation only between individuals of the same morph confirm reproductive isolation, supporting the occurrence of two species. Morphological and behavioural data are consistent with courtship-role-reversal hypotheses for the minor morph, constituting the second report in spiders of this atypical behaviour.

This study examined arthropod community patterns over an altitudinal ecoregional zonation that extended through three ecoregions (Yungas, Monte de Sierras y Bolsones, and Puna) and two ecotones (Yungas-Monte and Prepuna) of Northwestern Argentina (altitudinal range of 2,500 m), and evaluated the abiotic and biotic factors and the geographical distance that could influence them. Pitfall trap and suction samples were taken seasonally in 15 sampling sites (1,500–4,000 m a.s.l) during one year. In addition to climatic variables, several soil and vegetation variables were measured in the field. Values obtained for species richness between ecoregions and ecotones and by sampling sites were compared statistically and by interpolation–extrapolation analysis based on individuals at the same sample coverage level. Effects of predictor variables and the similarity of arthropods were shown using non-metric multidimensional scaling, and the resulting groups were evaluated using a multi-response permutation procedure. Polynomial regression was used to evaluate the relationship between altitude with total species richness and those of hyperdiverse/abundant higher taxa and the latter taxa with each predictor variable. The species richness pattern displayed a decrease in species diversity as the elevation increased at the bottom wet part (Yungas) of our altitudinal zonation until the Monte, and a unimodal pattern of diversity in the top dry part (Monte, Puna). Each ecoregion and ecotonal zone evidenced a particular species richness and assemblage of arthropods, but the latter ones displayed a high percentage of species shared with the adjacent ecoregions. The arthropod elevational pattern and the changes of the assemblages were explained by the environmental gradient (especially the climate) in addition to a geographic gradient (the distance of decay of similarity), demonstrating that the species turnover is important to explain the beta diversity along the elevational gradient. This suggests that patterns of diversity and distribution of arthropods are regulated by the dissimilarity of ecoregional environments that establish a wide range of geographic and environmental barriers, coupled with a limitation of species dispersal. Therefore, the arthropods of higher taxa respond differently to the altitudinal ecoregional zonation.

Abstract. Ikhsan Z, Hidrayani, Yaherwandi, Hamid H. 2020. The diversity and abundance of Hymenoptera insects on tidal swamp rice field in Indragiri Hilir District, Indonesia. Biodiversitas 21: 1020-1026. Hymenoptera is one of the four largest insect orders and it plays a vital role in human life as pollinators, parasitoids, and predators. Hymenoptera parasitoids are particularly important as agents of biological control of pest. The objective of this research was to study the diversity and abundance of Hymenoptera on tidal swamp rice field in Indragiri Hilir District, Riau Province, Indonesia. Samplings were conducted in 3 sub-districts of rice production centers, namely Batang Tuaka, Keritang and Reteh, using four trapping techniques (i.e. insect net, malaise trap, pitfall trap, and yellow pan trap). Shannon diversity index (H '), Krebs evenness index (E), and Jaccard similarity index (Is) were calculated. We found 4,701 individuals consisting of 39 families and 319 species of Hymenoptera at the three studied areas. Tidal swamp rice in Indragiri Hilir District had a high species diversity of Hymenoptera parasitoids and Hymenoptera predators, but a moderate species diversity of Hymenoptera pollinators. Species diversity and evenness of Hymenoptera parasitoids and predators were higher in Keritang than in Batang Tuaka and Reteh. The families of Formicidae, Braconidae, Ichneumonidae, and Scelionidae had the highest number of species, while Formicidae, Scelionidae, Diapriidae, and Braconidae had the highest number of individuals. Based on these findings, the abundance and diversity of Hymenoptera insects in Indragiri Hilir District have the potentials to be developed as biological agents to control pests on tidal swamp rice in this area.
