Pest attacks on rice plants can cause a detrimental decrease in production. Hymenoptera has many important roles in ecosystems, including as parasitoids and predators of pests. The purpose of this study was to determine the presence of Hymenoptera around tidal swamp rice in Indragiri Hilir Regency, Indonesia. Sampling used four traps, namely: 1) swing net; 2) yellow pan trap; 3) malaise trap; and 4) pitfall traps. The analysis was carried out by calculating the Shannon-Wiener diversity index (H'), the Margalef species richness index (D), the Pielou species evenness index (J). Hymenoptera found around tidal swamp rice areas of Indragiri Hilir Regency were 15.253 Hymenoptera insects consisting of 11 superfamilies, 37 families, and 304 morphospecies. Hymenoptera parasitoid had the highest diversity index value (4,80), followed by Hymenoptera pollinator (3,13) and Hymenoptera predator (3,11). The number of species of Hymenoptera parasitoid, pollinator, and predator obtained was 243; 31 and 76 species. The high diversity of Hymenoptera around tidal agricultural land optimizes its ecological role in the rice plantation ecosystem.

Indonesia has a high diversity of ant species, but much remains unreported. In agricultural habitats, ants can act as predators, decomposers, and bioindicators for agricultural ecosystems health. This research aimed to study the species diversity of Formicidae on tidal swamp rice fields in Indragiri Hilir District. Sampling was carried out in two periods of rice planting. Samples were conducted in 4 sub-districts of rice production centers, namely BatangTuaka, Keritang, Reteh, and Tembilahan Hulu, using four sampling techniques (i.e., insect net, malaise trap, yellow pan trap, and pitfall trap). Diversity index (H ), Species richness index (d), Species Evenness index (J), and Similarity Index (Is) were calculated. We found 5,754 individuals consisting of 5 subfamilies and 43 species of Formicidae at the four studied areas. Subfamily Myrmicinaehas the highest individual abundance, 2.578 individuals, followed by subfamily Formicinae1.823 individuals, subfamily Ponerinae 776 individuals, subfamily Dolichoderinae 575 individuals, and subfamily Pseudomyrmecinae 2 individuals. Diversity of plant species and environmental factors can affect the diversity index, species abundance, and abundance of individual Ants.

Petungkriyono forest is a tropical rainforest with high biodiversity. The increasing tourism activities in Petungkriyono lead to land conversion. Dragonfly (order Odonata) is a good bioindicator for aquatic and terrestrial. This study aimed to compare the community structure of Odonata in natural forests and tourist sites. The method of collecting imago Odonata was done by direct searching, samples were captured using sweep netting. The results showed that the dragonflies found in all locations consisted of the same family, 2 families (Gomphidae and Libellulidae) from the suborder Anisoptera and 6 families (Calopterygidae, Chlorocyphidae, Coenagrionidae, Euphaidae Platycnemididae, and Platystictidae) from the suborder Zygoptera. The total species of dragonflies found in Sokokembang were 15 species with a total of 293 individuals, Tirta Muncar 13 species of 287 individuals, Karanggondang 17 species of 276 individuals, and Curug Lawe 14 species of 242 individuals. The highest relative abundance of individuals was in the natural forest of Sokokembang is Drepanosticta spatulifera (26.28%) and in Karanggondang Vestalis luctuosa (24.64%), while in the tourist forests of Tirta Muncar and Curug Lawe were Euphaea variegata (34.84% and 28.51 %). The structure of the Odonata community is based on the Shannon-Wiener diversity index in the natural forests of Sokokembang (2.18) and Karanggondang (2.21) at the tourist sites of Tirta Muncar (1.84) and Curug Lawe (2.11). The results showed that the structure of the Odonata community based on the level of the diversity index value, evenness index, and dominance index in natural forests and tourist sites in Petungkriyono forest was not significantly different.

The contribution of six well-established coconut plantations to the conservation of biodiversity, specifically of ants, was investigated using soil sifting, timed hand collection and honey baiting along five, 100 m transects established in each plantation. Twenty honey-baited pitfall traps were set throughout each sampling area of each plantation. Collected worker ants were preserved in 70% ethanol and sorted and identified to the furthest possible taxonomic levels under a low-power stereo-microscope. The ant species observed at the five transects in each plantation were tabulated and species richness and proportional abundance of each species at each plantation were recorded. The Shannon-Wiener Diversity index for the ant assemblage at each plantation was calculated. Air and soil temperature, soil humidity and soil pH at each locality were also measured. A diverse ant assemblage occurred at each plantation, where between 19 and 29 species in 4 or 5 subfamilies were recorded; the Shannon-Wiener diversity index values were determined. Higher proportions of formicines and myrmicines than those of other subfamilies were observed. Two or more species in higher proportions than the rest of the ants occurred in each assemblage. Also, the six plantations shared three species and five plantations shared nine species in common. The considerable diversity of ants indicated a healthy environment and provided insight into the presence of other animals in the well-established coconut plantations.

Abstract: The objective of this work was to survey soil ants in Bt and non-Bt maize (Zea mays) crops, and to compare their effect on the soil ant community. Nine pitfall traps, 10 m apart, were installed in a central area (900 m2) of each of the following treatments (2,500 m2): conventional maize; maize modified with the Cry1F, Cry1Ab, and Vip3A proteins; and a native vegetation area. Fortnightly collections were conducted during four periods (complete producing cycles) of the crop, from 2011 to 2013. The number of ant species varied from 25 in Bt maize (Vip 3A) to 58 in Bt maize (Cry 1F). The treatment with conventional maize showed the highest Shannon-Wiener diversity index (H’ = 2.60). Jaccard’s index showed that there is dissimilarity between the cultivated maize areas and the native vegetation area in most treatments, and that Bt and non-Bt maize show similarity in their soil ant assemblages. The cultivation of Bt maize does not affect the soil ant community. The subfamily Myrmicinae shows the highest number of species in all the collection periods, with 57, 41, 47, and 50 species in the first, second, third, and fourth periods, respectively. The genus Pheidole, belonging to this subfamily, shows the greatest number of species.
