Abstract

Bali has the potency to grow plantation, particularly cacao plants (Theobroma cacao). The increase of cacao production is supported by the increase of the number of productive cacao plants, but the production rate per hectare per year decreased at some districts. One reason of the decreasing cacao production was due to the attack of Plant Disease Organism. This research aimed to investigate the insect families associated with cacao plantations and the fuctions of the insects on cacao plants, at Bedulu Village, District of Blahbatuh, Gianyar Regency. Samples were collected from January to February 2011 and insect identification was conducted for two months at Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Udayana University. Field sample collections were arranged by randomized sampling techniques that the block samples were chosen randomly. Samples were collected with beating technique and trapping with sex pheromone. All insects collected from the field belong to eight groups/types. The highest percentage of insect type collected fuctioned as vector (56.1%) and the lowest was acted as parasites (0.1%). The highest number of two groups insects captured were groups of pests and predators. The insect that function as biological control was the family of Labiduridae, Anthocoridae, Reduviidae, Chrysopidae, Gryllidae and Chalcididae.

Abstract

Research on reproduction patterns of Balinese snake skin fruits (Salak Bali) has been conducted by identifying the availability of pollens on anthers of male and hermaphrodite flowers, the viability of pollens in the pistillum and the present of embryo(s) in the ovulum. Flower samples were collected from Sibetan and Muncan Villages, Karangasem regency. Sample preparations and identifications were conducted in "Stuktur dan Perkembangan Tumbuhan Laboratory" Department of Bilogy, FMIPA Udayana University. The results showed that the pollen has a single apperture, unisulcus, minuta, oblat sferoidal type. The length of polar axis was 15-24 jam (P) and equatorial diameter of 16-24 |im (E). Therefore, the P/E index was 0.99-1.0. The pollen viability before and after anthesis of hermaphrodite flowers was low (71.4% and 50.6% respectively), with very low pollen tube germinations (0.08% of before and 0.48% after anthesis). Similarly, on the anthers of male flowers, the viability of pollens before anthesis was low (75.7%) with pollen germination of 0.18%, and event lower in after anthesis flowers (28.8%) with 0.29% pollen tube germination. Squashed stigma before and after anthesis and 2 days after flowers were opened showed that there was no germination occurred. Therefore, there was no germination in the pistillum, but the embryo developed before flower anthesis, indicates that the reproduction pattern of Salak Bali occurred without fertilizations (agamospermy).

Abstract

A research on spatial distribution of Mollusc inhabitant seagrass bed at Merta Segara Beach Sanur, Denpasar was carried out from October to December 2012. The study site is well recognized as a place of tourist activities. Line transects with quadrate methods were applied as the sampling technique. Samples were collected in a total of 60 quadrates (10 m x 2.5 m) from four line transects with the interval of 50 m between each transect. At a sampling point chosen randomly, one transect was lined up toward the sea, then on each side of transect, 15 quadrates were laid with the interval of 20 m. The study found 31 individuals which 24 were classified as Gastropods, and 7 individuals classified as Bivalve. Overall, the study indicated that the Mollusc communities were in stable condition (H’= 3,74 and E= 0,75). The horizontal distribution of Mollusc was neither associated with seagrass percentage cover or the use of jetty piling. The spatial distribution seemed related to the use of area as tourist activities.

Abstract

A study on mollusks (Amphidromus peversus) has been carried out on Udayana University, BukitJimbaran (Bali, Indonesia) campus between November, 2003- November, 2005. The study was undertakenon a secondary forest on a limestone dry soil with dominant vegetation of Glerecydium sepium, Lantanacamara, Ceiba pentranda, and Acasia auriculiformis. Samples were randomly taken on quadrate samplings.Mollusks were captured on the land surface or on living vegetations. Results of the study showed that A.peversus has an average of shell length of 27.9 mm, shell width 18.0 mm , and body weight 7.90 g, number ofshell whorls 5.3, with the proportion of direction of whorl to the right of 55.3%. The shell of A. peversus hasno operculum. The color of the shell was yellow with brown stripes.The relationship between shell length (X) and with body weight (Y) can be represented by theequation of Y = 0.473 X – 5.32 (R2 = 11.9 %), which showed week relationships between those parameters.Meanwhile the relationships between the shell length (X1), width (X2) and body weight (Y) was best fitted bythe following equation : Y = 0.289 X1 + 0.0140 X2 – 3.47 (R2 = 94.9%).

Abstract

ABSTRACT Rearch on “Biodiversity of Dragonflies in Petulu Village, Ubud District, Gianyar Regency, Bali” was undertaken between May and October, 2020. Objectives of this research were to find out species and biodiversity of dragonflies of Petulu Village. Sample were collected from some research locations representing different habitats, such as rice fields, settlements, and plantations. Dragonflies which were caught or sighted on research area whould be caught by insect nests when possible and then were brought to the laboratorium at Biology Department-Fmipa Udayana University, Bali for species identification. Identification was conducted refering to some books and manuals, such as Wahyu Sigit Rhd (2013), Lilies S. (1992), etc. Data of dragonflies that were recorded including name of species and their relative abundances, and then the results were presented on a table. The status of each species (protected or not), was also provided. Shannon-Wiener diversity indexes were calculated. Results of this research showed that there were 12 species of dragonflies found, namely: Crocothemis servilia, Pantala flavescens, Orthetrum Sabina, Neurothemis terminata, Diplacodes trivialis, Potamarcha congener, Neurothemis ramburii, Orthetrum chrysis, Ischnura senegalensis, Agriocnemis femina, Agrionoptera insignis, dan Agriocnemis pygmaea. All dragonflies species found here were not protected by law. Biodiversity index (H’) of dragonflies in Petulu Village was 1.63, which indicated condition of community structure of dragonflies in Petulu Village was stable within the category of moderate.
