<p>Plants that have a wide range of insect presence, decreased insect diversity and abundance were so few consequenced because the absence of one insect species can be replaced by the presence of another. The bad consequences that occur are the types of plants that have specific insect specificities because the absence of these insects will cause the failure of plant pollination and will directly cause a decrease in crop production. This study aimed to determine the diversity of insect species that come in the soybean-tithonia intercropping. The method was used direct observation in tithonia-soybean intercropping, took insects using a sweep net in the morning. The results showed that there were 15 types of insects identified, namely <em>Epilachna</em> sp.; <em>Coccinella</em> <em>sexmaculata</em>; <em>Coccinella</em> <em>transveralis</em>; <em>Verania lineata; Ropalidia fasciata; Priocnemis</em> sp.; <em>Naupactus leucoloma; Piezodorus guildinii</em>; <em>Bemicia</em> <em>tabaci; Agromyza phaseoli; Spodoptera</em> sp.; <em>Nezara viridula; Paederus fusipes; Hylaeus</em> sp.; and <em>Trigona</em> sp. The range of results of the calculation of the diversity index showed that the five treatments in intercropping plants had the same abundance. So it was needed to calculate the highest diversity index value or maximum H expressed in Ln S. The maximum H value in this study is 2.708, which is a measure of moderate species diversity (1&lt;H’&lt;3).</p>

The activities of the community around the peat swamp forest cause disruption of the ecosystem from the sustainability of the forest area's resources. Land clearing and peatland fires also affect the presence of ferns. The new environmental conditions due to changes in land cover cause ferns to be affected by these changes. Kuala Dua Village Kubu Raya Regency has secondary peat swamp forest and open peat land due to fires 3-4 years earlier so it is overgrown with a variety of new types of flora, one of which is a type of fern. The objective of the study is to describe species diversity of ferns and their site conditions in secondary peat swamp forests and open peatlands of Kuala Dua Village, Kubu Raya District. This research was conducted with survey method using multiple plot samples. The plots determination was done by purposive sampling which was taken place on the site where there were many species of ferns land. Three plots were on each land covered condition with a plot size of 5 m x 5 m that divided into 25 of a 1 m x 1 m sub plots. The results show that 5 species of ferns found in peat swamp forest and 4 species of ferns were found on open peatlands. The species that has the highest INP value in the forest was Asplenium belangeri and the species that has the INP value in open peatland was Nephrolefis falcata. Dominant Index, Spesies Diversity Index and Spesies Abudance Index were 0,12 and 0,18; 0,30 and 0,36; 0,51 and 0,52 on the forest and open peatland respectively. The Similarity Index value (IS) of ferns in secondary peat swamp forest and open peatland is 44%. The study shows dissimility of species fern in peat swamp forests and open peatlands.Keywords: Open peatland, Pteridophyta, secondary peat swamp forest

A study on diversity and abundance of grasshopper and its relatives (Orthoptera) was conducted at two mountainous rainforest ecosystems (Mounts Kendeng and Botol) of Gunung Halimun-Salak National Park. A hundred meters of a line transect was used to sample and set up several insect traps (yellow pan, malaise, pit fall, bait pit fall, sweep net, and light traps), and insect sweepings as well. The light traps were set up at about fifty meters distance from the end of the sampling sites. A total individual collected by traps was combined on every comparable sampling site. Total individuals of the Orthoptera captured were 414; consisted of 25 species of 9 families. Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol. Number of species of each family usually similar except on family of Grillidae was much higher at Mount Kendeng. Species belong to Phasmidae was not recorded at Mount Kendeng, while species belong to both families of Gryllotalpidae and Tettigonidae were not captured at Mount Botol as well. Overal there was a difference in the species richness at each between. Shannon Diversity Index (H’) and evenness (E) were higher at Mount Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66). Similarity Index of Jaccard (Cj) and Sorenson (Cn) of both localities were similar (0.40 and 0.32). Herbivores were most dominant at both localities (Phasmidae, Tetrigidae, Acrididae, Gryllidae, dan Gryllotalpidae), followed by omnivores (Blattidae), scavenger (Gryllacrididae), and predator (Mantidae).

Abstract The role of insects as pollinators within plant communities is well established, yet our knowledge of insect biodiversity in many habitats is lacking. Given the growing concern that insect biodiversity is declining, it is increasingly important to document insect assemblages from a wide range of geographic locations and habitats. Pan trapping is a common means of sampling local insect diversity. Many studies have found different insects associated with different-coloured pan traps. Here, eight different-coloured pan traps were used to sample local insect diversity in habitats supporting Platanthera (bog and rein) orchids on Vancouver Island, British Columbia, Canada. A total of 16 sites supporting seven orchid species resulted in 435 insects from 53 families being caught over 64.9 hours of pan trapping. Both Shannon and Simpson diversity index values were low despite sampling in markedly different habitats. Yellow traps caught higher numbers of insects, but no statistical difference was found among colours overall. No activity indicating pollination was recorded from a total of 254 insect observations over 21.5 hours. Our results contribute important baseline data on the diversity and behaviour of insect communities in orchid habitats of Vancouver Island and on the use of pan traps to characterise insect communities.

The study was designed to investigate the insect diversity and its economic importance in Agulu and Nanka gully sites using standard procedures. A total of 1,609 insects belonging to 15 species were identified from the study sites, which comprised of 1026 individuals belonging to 15 species from Agulu and 583 specimens belonging to 8 species from Nanka. The diversity of the insect species highlighted the dominance, diversity index, species richness and species evenness. Blattodea were the most dominant order in both Agulu site (43.27%), and Nanka site (56.60%). The order Blattodea was the most diverse (0.725) in Nanka site, whereas the order Coleoptera was the most diverse (0.740) in Agulu site. Results from the economic importance revealed 8 insect species as harmful, 3 species as beneficial, while 4 insect species were considered as both beneficial and harmful. Beneficial insects are edible and good agents of pollination while the harmful insects devour agricultural produce and stored food. The result of this study shows that gully erosion site is dominated by insect diversity, probably due to the flora regeneration.

The Dipterocarpaceae family is one of the identified plant groups with high conservation value that exist in Weh Island Nature Tourism Park. However, the data availability on the species diversity and population structure of Dipterocarpaceae in Weh island in particular and Aceh in general is still very limited. Thus, it is necessary to conduct studies on species diversity and population structure of Dipterocarpaceae from Weh Island. This study aims to obtain data on species abundance and diversity, species composition of each stratum, population structure, and stand structure of Dipterocarpaceae in Weh Island Nature Tourism Park. This research utilized transect method with randomly selected plots according to topographic conditions. We found two Dipterocarpaceae species: Shorea sumatrana (Slooten) Desch and Dipterocarpus hasseltii Blume. Shorea sumatrana (Slooten) Desch has the greatest abundance of all types and strata. The diversity of Dipterocarpaceae species in Weh Island Nature Tourism Park is categorized as low because the diversity index value is in the range of H'1. This means that the presence of seedling and sapling strata from each species has a major effect on the survival of the Dipterocarpaceae family in the future. The stand structure of the Dipterocarpaceae family in normal conditions is indicated by an inverted “J” shaped diagram.
