<p>Sago (<em>Metroxylon sagu</em> Rottb) in Maluku grow naturally to form sago forest ecosystem. Hymenoptera in the sago forest ecosystem has not been studied. This study aims to examine the diversity of Hymenopterous parasitoids in sago forests in Maluku. The research was conducted in Ariate, Eti, Waisamu, Rutong, Tawiri, and Tulehu in September 2015 - October 2016. Hymenopterous parasitoids were collected through swing nets, light traps, yellow pan traps, and pitfall traps. Results the abundance of hymenopterous parasitoids in six sago areas in Maluku was found to be 14 families and 32 species. The morphoses of morphospecies are 68 morphospecies of Sago Ariate forest 32 morphospecies, Eti 37 morphospecies, Waisamu 9 morphospecies, Rutong 11 morphospecies, Tawiri 19 morphospecies, and Tulehu 37 morphospecies. The high diversity index (2.18 - 3.55) per location, Morphospesies wealth of Tulehu is  higher than other location, while the individual abundance of Ariate is higher than other villages. The average relative abundance of Scelionidae, Scoliidae and Ichneumonidae families was higher by 26.46%, 15.95%, and 10.89%, respectively. There are three families with high morphospecies and individual abundance in each sago area ie Scoliidae in sago forest area of Ariate and Waesamu, Scelionidae on Rutang, Eti, and Tawiri sago wood area, while Eulophidae on sago Tulehu area. There are 12 unique species or species with only certain locations and none in other locations, each Ariate (2 species), Eti (2 species), and Tulehu (8 species).</p><p>ABSTRAK</p><p><br />Sagu (Metroxylon spp.) merupakan tanaman sosial, budaya dan ekonomi di Maluku dengan potensi hutan sagu cukup tersedia.

 Mount Merapi National Park (MMNP) is a natural con-servation area with the main function of preserving the diversity of plants, animals and their ecosystems. In 2010, Mount Merapi suffered a large eruption which caused damage to the forest ecosystem inside. One of the locations that suffered severe damage was at Cangkrin-gan Resort. After the eruption, the affected vegetation began to grow again. The purpose of this study is to monitor and determine the di-versity of secondary forest plants in the MMNP area. The method used was a method of path and use a point-intercept transect as the sam-pling unit. The results showed that after the eruption, the Acacia de-curens dominated at each level starting from sapling, poles and trees. Based on the results of the study showed that the eruption of Mount Merapi that occurred in 2010 resulted in a change in vegetation struc-ture in the area with the Shannon-Weiner diversity index which is still low, amounting to 1.86 for seedling, 1.32 for the sapling and 0.22 for poles. At the tree level 100% is still dominated by Acacia decurens.

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.

The composition of the terrestrial arthropod community of a tidal marsh islet in the Gulf of Gabes (Tunisia) was studied during two seasons (spring, autumn). The study was conducted on a small islet located in an area where the highest tidal excursions of the Mediterranean occur. Standard trapping methods (pitfall traps, mobile cages) were used to evaluate specie richness and abundance in different areas of the islet. Diversity indices were calculated for coleopterans and isopods alone. The structure of the arthropod community varied a great deal from one season to the other and differences were found when seaward areas were compared with landward ones. El Bessila presented a particularly rich beetle community whereas only few isopod species occurred. The moderately high diversity levels found for the beetle indicate the influence of the high tidal excursions in modelling the structure of the community.

This study evaluated the Arctiini fauna of the Serra do Pardo National Park (Pará, Brazil) between 22 September and 3 October 2011. Light traps were left one night in each sampling site (SS) from 18:00 h to 6:00 h of the next day. The following parameters were evaluated: richness (S), abundance (N), diversity index (H’), Shannon uniformity (U) index, and Berger-Parker dominance (BP). Richness was estimated using the non-parametric methods Chao1, Chao2, ACE, ICE, Jackknife1, Jackknife2 and Bootstrap. A total of 3,247 specimens were captured, belonging to 221 Arctiini taxa; 32 of these are new records for the state of Pará and, of these, six are new records for the Brazilian Amazon. The Arctiini fauna is very rich and uniform. The richness estimator and rarefaction curve indicated the need for increased sampling efforts in the area.

AbstractPollen is the main food for honeybee broods and young workers and so colony development and reproduction rely heavily on pollen availability, both spatially and temporally, in the environment. Intensification of agriculture and climate seasonality are known to alter honeybee foraging patterns and pollen intake through changes in resource availability in temperate regions; however, little is known about how honeybees respond to such environmental factors in tropical regions.Pollen species collected by honeybees in a Neotropical agricultural region of Colombia were identified. The effects of landscape structure (landscape Shannon Diversity Index, forest area in 1000 m around the apiary) and climate seasonality (mean monthly precipitation) on the amount, richness and diversity of pollen collected by the honeybees were evaluated for all pollen species together and pollen species segregated according to forest and anthropic areas (croplands, grasslands, woodlands, urban areas).Honeybees were found to be much more associated with anthropic than forest pollen species regardless of landscape structure or precipitation. However, the amount, richness and diversity of pollen from all species and forest species responded positively to landscape diversity and forest area, suggesting an advantage for honeybees in obtaining small quantities of pollen from forest species, in spite of being well-adapted to forage in anthropic areas. Precipitation was found not to be related to the overall amount and overall richness of pollen collected by honeybees, suggesting that climate seasonality was not an important factor for pollen foraging. Nonetheless, overall pollen diversity was negatively affected by precipitation in less diverse landscapes, while anthropic pollen diversity was negatively affected in more forested landscapes. These findings are compared with those from temperate regions, and the implications for honeybee productivity and survival, and their interactions with Neotropical native species, are discussed.

A comprehensive inventory of faunal biodiversity was conducted within three Key Biodiversity Areas of Central Visayas. Mt. Bandilaan Natural Park (MBNP), Balinsasayao Twin Lakes Natural Park (BTLNP), and Rajah Sikatuna Protected Landscape (RSPL). Three primary wildlife groups were surveyed: bats, birds and amphibians. Species diversity and population trends were then analyzed to assess areas of biodiversity importance. RSPL generally had the highest species richness and diversity index while MBNP consistently had the lowest. When pooled. The surveyed areas resulted in a high diversity index and rate of endemicity showing the importance of multiple areas of protection. These findings can be utilized to prioritize habitat protection as well as to serve as a baseline information for future biodiversity inventories. J. Biodivers. Conserv. Bioresour.

The aim of this work was to study the effect of post-harvest forestry residue management practices on the epigeal coleopterans diversity and abundance in a 1-yr old Pinus radiata plantation. Approximately 25-yr old P. radiata plantation was available, which was harvested by clear-cutting at the beginning of 2010 in Constitución, central Chile. Three post harvest residue management treatments were installed in a fully randomized design in blocks: 1) a control, where residues were intact left; 2) residue removed (> 2.5 cm diameter); and 3) burned. The coleopterans were sampled in spring and summer, using linear transects with pitfall traps. The abundance and richness, and diversity index of coleopterans were determined. A total of 23 species of 13 families were obtained. Both in the springand summer, the treatment with residues left registered significantly greater abundance and species richness. In the residue management, the practices of intact leaving residue should be considered as the least impacting on diversity and abundance of epigeal coleopterans and is recommended for creating refugee areas to promote diversity of beetles in this area of study.

This study aims to determine the diversity of insects and plants used as a habitat in unburned and previously burned peat land forests in Palangkaraya, Central Kalimantan. Insects were collected by beating the branches of plants, aerial sweeping, pitfall traps and light traps. Plants were identified in situ or plant samples were collected and identified later in the Lab. The diversity of insects were compared between unburned and previously burned peat forests by analyzing its index diversity (H’) and index of similarity (IS). In total, the insects collected from unburned peat forest were 551 individual, belongs to 12 order and 51 families, and 431 individual insects were collected from previously burned peat forest which belongs to 10 order and 38 families. The family of insects that most frequently found at both areas was Formicidae (Hymenoptera). The insects diversity of both forests were still high, that is H' = 3,45 of unburned peat forest and H '= 3,11 of previously burned peat forest, with the similarity index IS > 50% of both peat forests. The number of plant species found was higher in unburned peat forest (38 species) than in previously burned peat forest (9 species).  The previously burned forest was dominated by Acacia plants, while in unburned peat forest the plants seem to evenly spread.
