Nocturnal Coleoptera and Hemiptera Diversity at  Giam Siak Kecil Bukit Batu Biosphere Reserve Indonesia

Giam Siak Kecil Bukit Batu is a biosphere reserve which one of its functions is as a habitat for wildlife. However, biodiversity data in the Giam Siak Kecil Bukit Batu Biosphere Reserve (GSKBB-BR) is still very minimal, including insects (Coleoptera and Hemiptera). This research was conducted to determine the diversity of Coleoptera and Hemiptera in the GSKBB Biosphere Reserve, Riau, Indonesia. The research was carried out using an exploratory method using "lights trap". The results of the study found 30 species, from 11 families of the order Coleoptera (23 species) and Hemiptera (7 species) in the GSKBB-BR. The diversity index of Coleoptera and Hemiptera at the observation site was moderate (H = 2.73), with a high evenness index (0.80). Scarabaeidae (order Coleoptera) is the family with the highest number of species found (8 species), while the most abundant species were Tibicen linnei and Pomponia fusca (Cicadidae/Hemiptera). Based on their functional roles, Coleoptera and Hemiptera with the highest number are herbivores (17 species), followed by predators (7 species) and decomposers (3 species). The range of values for temperature and humidity at the research site are in normal conditions. The GSKBB-BR area is an important remaining habitat for wildlife in Riau, including various types of insects (Coleoptera and Hemiptera); whose potential still needs to be revealed, and must be managed properly.

The presence of flowering plants is essential to the conservation of natural enemies in some particular ecosystems, such as agroecosystem. The objectives of this research were to determine the natural enemies associated with refugial flowering plants Zinnia elegans, Cosmos sulphureus, and Tagetes erecta planted in the rice bunts. The research took place in the rice farms in the villages of Jatisarono, Wijimulyo, and Tanjungharjo, Nanggulan Regency, Kulon Progo, District. The natural enemies were observed using three different methods: insect nets, pitfall, and direct observation. The observations were conducted in the morning, between 07.00-10.00 a.m., with an interval twice a week for 8-weeks. The natural enemies were identified to the family level. Diversity index (Shannon-Wienner), evenness index, and dominance were calculated for each plant. The diversity index for Z. elegans, C. sulphureus, and T. erecta fell in the category of medium ranging from 1.328-1.581 with medium evenness (0.365-0.574) and high dominance of 0.314-0.453. Natural enemies associated with C. sulphureus and Z. elegans were more compared to those associated with T. erecta.

The fire experimental plot of a total landed area of 0.174 ha was divided into three equal parts designated Plot A, Plot B and Plot C, corresponding to the early burnt, the late burnt and the control plot, respectively. Out of the 15 species of trees identified, six species belong to Fabaceae- Mimosoideae family and other families represented are Combretaceae, Meliaceae, Lamiaceae, Rubiaceae, Anacardiaceae, Urtiaceae and Sapotaceae. Gmelina arborea was the most abundant species and it was found in plot A, B and C. The diversity indices enumerated were Dominance index, Simpson index, Shannon index or diversity index and evenness index. Plot C had the highest abundance (species count), followed by Plot A and Plot B. While Plot B depicted a high dominance, dominance was low in Plot A and lowest in Plot C. This means that a particular species was dominating Plot B, which was Gmelina arborea. This Gmelina arborea also dominated Plot A but to a lesser extent compared to Plot B. Plot C was richer in species than Plot A and Plot B. The Shannon index was low across the three plots, but considerably highest in Plot C. Evenness index was moderate at Plot C, implying that there was an even distribution of tree species in Plot C, while evenness was low at Plot A and Plot B. Comparing the present data with the older data, it is clear that the fire experimental plot has undergone deforestation over the years, which requires urgent attention and reforestation.

This study was conducted using two types of light traps to collect the insects at Mae Tam Reservoir from January to April 2018. The sampling area was divided into 4 points. Two points were located at the reservoir’s bank, and the others were located at the reservoir’s outlet. The study aimed to compare the efficiency of the fluorescent tube's blue and purple light, which had a different wavelength on insect’s attraction. To compare the diversity of Trichoptera in the different stream habitats, Sørensen similarity index, Shannon-Wiener index, and Evenness index were used. The result showed that purple light could attract insects better than blue light. Hymenoptera was attracted by purple light. Coleoptera and Hemiptera were attracted by blue light. The study on the diversity of Trichoptera showed that there were 2,534 individuals of 9 families 48 species were collected. Ecnomus puro was the most abundant species (1,120 individuals). The highest Shannon-Wiener diversity index was sampling points 4 (2.10). The highest Evenness index was sampling points 4 (0.62). Sørensen similarity index showed that sampling points 3 and 4 had the highest value (67.92 %) because they were adapted from a natural creek to concrete where boulder, gravel, cobble, sand, and woody material were deposited at the stream bottom. These provided various microhabitats for insect larva to live and develop. The riparian had affected the distribution and colonization of mature insects.

The diversity of butterfly species was studied from January to June 2015 in the three selected areas, viz. Ramna Park, Jagannath University Campus, and Baldha Garden in Dhaka city, Bangladesh. A total 75 species of butterfly belonging to 42 genera under 8 families were recorded from the study areas during the study period. Of them, 52 species (6253 individuals) of 8 families were found in the Ramna Park, 37 species (1430 individuals) of 7 families in the Jagannath University Campus and 20 species (320 individuals) of 6 families in the Boldha Garden. In these three study areas, 17 species, 14 genera and 6 families were in common. At the Ramna Park, the highest species richness included the family Lycaenidae (21.15%, 11 spp.) followed by Papilionidae (17.31%, 9 spp.), Pieridae (17.31%, 9 spp.), Nymphalidae (17.31%, 9 spp.), Hesperiidae (13.46%, 7 spp.), Danaidae (7.69%, 4 spp.), Satyridae (3.85%, 2 spp.), and the lowest was in the family Acriidae (1.92%, 1 spp.). At the Jagannath University Campus the highest number of species were recorded in the family Lycaenidae (21.62%, 8 spp.) and Hesperiidae (21.62%, 8 spp.) followed by Pieridae (18.92%, 7 spp.), Papilionidae (13.51%, 5 spp.), Nymphalidae (10.81%, 4 spp.), Danaidae (10.81%, 4 spp.), and the lowest was in Satyridae (2.70%, 1 spp.). The topmost butterfly species were recorded in the family Pieridae (25%, 5 spp.) followed by Lycaenidae (20%, 4 spp.), Nymphalidae (20%, 4 spp.), Papilionidae (15%, 3 spp.), and the lowest from the family Hesperiidae (10%, 2 spp.) and Danaidae (10%, 2 spp.) at the Baldha Garden. The maximum butterfly species were found in February to June (51 spp.), February (34 spp.), and April (16 spp.), and the lowest were in January (46 spp.), June (21 spp.) and January (8 spp.), respectively for the Ramna Park, Jagannath University Campus and the Baldha Garden. The peak of the population observed in May (n =1285), March (n = 325), and May (n = 71), and the lowest was in January (n = 662), June (n = 145) and January (n = 21), respectively for the Ramna Park, Jagannath University Campus, and Baldha Garden. The Shanon’s Diversity Index (H) and Simpson’s Index (λ) indicated high butterfly diversity at the Ramna Park (H = 3.68, λ = 0.03), Jagannath University Campus (H = 3.20, λ = 0.06) and Baldha Garden (H = 2.50, λ = 0.13), respectively. The high Species Evenness in the Ramna Park (E = 0.93), Jaganath University Campus (E = 0.89) and the Baldha Garden (E = 0.84) indicated that the species were evenly distributed. The calculated Sorenson’s Coefficient (CC) was 0.47, which indicates that these three communities have quite a bit of overlap or similarity. Bangladesh J. Zool. 48(2): 413-428, 2020

Small islands are extremely vulnerable to ecosystem disturbances. One of the common factors im-pacting on island ecosystems is the rise of tourism activity and the associated conversion of man-grove forest’s function into tourism’s supporting facility. Those changes will ultimately affect the diversity of bird species inhabiting the island.  Therefore, this study aimed to analyse the structure of a bird community in the mangrove forests of the Pahawang Island. The study used the transect method with tracking implemented. The obtained data were analysed using the Shannon-Wienner diversity index. We recorded 28 species from 21 families. Out of 21 families, Columbidae had the highest number of species (three species). Seven feeding guilds were observed during the present study, the maximum number of species belonged to the insectivore group and the minimum – to the nectarivore and omnivore (1 species each) guilds. Based on the abundance rank, the most abundant species was the cave swiftlet (Collochalia linchi). Three of the recorded species are listed in the cat-egory “Protected” according to the Indonesia Law: the brahminy kite (Haliastur indus), sunda pied fantail (Rhipidura javanica), and the black-naped tern (Sterna sumatrana). All bird species that have been recorded during the present study is classified as “Least Concern” in the IUCN Red List. The values of the Shannon-Wienner index suggest neither high nor low diversity (H’ = 2.55). Mangrove forest ecosystems, including the mudflat on the Pahawang Island, are important supporting popula-tions of wild birds through providing foraging, roosting and nesting sites.
