741 Kyi Thar Khaing ABUNDANCE OF RED-EARED SLIDER TURTLE TRACHEMYS SCRIPTA ELEGANS (WIED, 1839) AND THEIR POTENTIAL IMPACTS ON THE NATIVE TURTLE SPECIES IN THE TEMPLE PONDS, YANGON ENVIRONS Species abundance of turtles and tortoises in the temple ponds, Yangon environs were observed in the study work. The study was conducted from 2015 to 2018. Distinctive characters and morphometric data of studied species were given systematically. Classification and identification of the individual specimens were also recorded with the sex. Trachemys scripta elegans (Redeared slider turtle) is one of the world’s most invasive species. They originated from North America and they have been considered as invasive species. The research designed was based on field study. It was observed on population status, the pet trade and distribution of the red-eared sliders turtle species. The population size of recorded turtles and tortoises were calculated for the sex and age groups (males, females, and juveniles) based on carapace length. Morenia ocellata and Lissemys scutata were the highest populations and the second highest population T. s. elegans were found to be recorded in all temple ponds. The population size of Red-eared slider (RES) turtle was composed of 6hatchlings, 10juveniles, 62adults (25males and 37females) with a percentage of 21% immature and 79% mature individuals. In Yangon, a large number of hatchling Red-eared sliders were sold at pet shops. The present study was the first attempt to record and present the current distribution and status of this invasive freshwater turtle. 2020
742 Myo Sandar Win BENEFICIAL SERVICES OF WETLANDS AND THEIR INDICATOR BIRD SPECIES IN WETLAND AREAS OF AYEYARWADY REGION The present research conducts with the beneficial services of wetlands and their indicator bird species in wetland areas of Ayeyarwady Region. Wetlands are critical habitats for wetland dependent bird species. These habitats are facing rapid degradation due to anthropogenic activities that affect the wetland indicator bird distribution by changing their habitats. Distance sampling point count method (Buckland et.al., 2004) was applied. Vegetation types were recorded by using the visual estimation. Vegetation covers were categorized by peripheral and mosaic by (Semeniuk et al.,1990). Field surveys were carried out from May 2017 to April 2018. During the survey period, 101wetland indicator bird species were recorded including three globally threatened bird species and four near- threatened bird species. These bird species were also indicate the wetland habitats. 2020
743 Yadanar Myo DIFFERENT TYPES OF FOODS FORAGED BY VARIOUS BIRD SPECIES IN PAKOKKU ENVIRONS, MAGWAY REGION Different types of foods foraged by various birds were investigated in four study sites of Pakokku environs during July 2015 to June 2016. A variety of foods including animal matters and plant matters was consumed by different bird species. The bird fauna in the study area was represented with 69 carnivorous species (54.77%), 53 omnivorous species (42.06%) and four herbivorous species (3.17%) according to the foods taken. The carnivorous birds were predominant due to the abundance of food sources for these birds to forage. The environs of Pakokku provide different food sources that are important for the existence of bird species inhabited in that area. 2020
744 Bauk Ra FORAGING PATTERN OF SOME BIRDS IN WAIMAW TOWNSHIP AND ITS ENVIRONS, KACHIN STATE A total of 52 species belonging to 17 families were selected for observation of foraging pattern during the May 2017 to April 2018. They are categorizied into 18 groups. The present study highlight the foraging pattern of there birds species based on the food eaten and habitat use. In present study, seven substrates (Above canopy (ABC), the upper understory (UUN), unshaded canopy (USC), emergent leaves (EME), lower understory (LUN), Shaded canopy (SHC) and ground (GRO)) were categorized in Waimaw environs. Among 15 groups preferably utilized upper understory (UUN) level for foraging and 13 groups, the unshaded canopy (USC) level were mostly utilized for foraging opportunities on there environ because vegetation offered suitable food in this area. 2020

746 Ma Nandar Moe Oo COLOUR PREFERENCE AND BITING BEHAVIOR OF MOSQUITOES ON THE SPECIFIC PARTS OF THE CATTLE BODY A monthly field study was conducted to determine the preferred biting behavior of mosquitoes on different specific parts of different coloured cattle body in Taikkyi Township, Yangon Region from March 2017 to November 2018. Outdoor cattle bait mosquitoes collection was done using WHO sucking tube from 18:00 hours to 24:00 hours for 3 days. Anopheles and Culex mosquitoes were collected for 45 minutes in every hour on the specific parts of the cattle body. Collected mosquitoes were placed in specific body parts labeled paper cups. Next day morning species identified was done all collected mosquitoes according to different mosquito identification key. Result revealed that the highest number (n=1798) of mosquitoes were collected in September followed by n= 1409 in March and lowest was collected in n=226 in May by cattle bait collection. The biting behavior of mosquitoes were found to be the highest (n=2592, 34.39%)on black cattle, followed by (2566,34.05%) on white cattle lowest was observed (2378,31.56%) on Brown coloured cattle. The highest number of biting behavior on specific part of body was found Elbow from Bracelets (1611, 21.38%) followed by Knee from Anklebone (1108, 14.70%), Fingertip (846,11.41% ), Tiptoe (887,11.77%) lowest was observed on Head (108,1.43%). When compared with specific parts of different parts of different coloured cattle was found the highest number of mosquitoes were collected from Elbow to Bracelets (n=552,21.51%) white, 522,21.95% on Brown and 537, 20.72% on Black cattle followed by 549 21.18% on Tiptoe of black cattle, 395, 16.61% and 430, 16.59% on Knee to Anklebone of Brown and black cattle body parts. Lowest mosquitoes were observed (13, 0.51%), (47,1.98%) and (48,1.85%) on Head of all White, Brown and Black coloured cattles. In conclusion biting behavior of mosquitoes were observed differ to different parts of the cattle body. Tiptoe, fingertip, Elbow from Bracelets and Knee from Anklebone were mostly bitten by mosquitoes. Mosquitoes were found highly attack to Elbow from Bracelets and Knee from Anklebone followed by tiptoe, fingertip of the cattles. Although very low on Head. 2020
747 Nyo Nyo Lwin PERFORMANCE EVALUATION ON NATURALLY MATED AND ARTIFICIAL INSEMINATION OF QUEEN BEES APIS MELLIFERA LINNAEUS, 1758 IN FIELD COLONIES Artificial insemination (AI) known as instrumental insemination, is a practice that is popularity among queen breeders. It provides a valuable tool to control the random mating process and is essential for bee breeding and research requiring specific crosses. Three study sites have been chosen as site (I) in Shan State (Aung Ban), site (II) in Bago Region (near Taungoo University) and site (III) in Mandalay Region (Yamethin). Study period lasted from December, 2017 to December, 2018. The study sites were chosen based on the migratory beekeeping method by flowering plants and seasonal changes condition of Myanmar. Artificial Insemination tool was composed of artificial insemination device, microscope, CO2 as anesthesia. Artificial Insemination process have inseminated on 30 virgin queen bees in 2018, totally. In site (I) in Taung Lay Lone, Shan State, AI process have inseminated on ten virgin queen bees, but none is survived and oviposition due to severe weather condition. Artificial insemination process has inseminated on ten virgin queen in site (II), of near Taunggoo University, Bago Region. Result has succeeded six AI mated queens in this area. In site (III) of Yamethin, Mandalay Region, AI process have inseminated on ten virgin queen bees have recorded seven AI mated queens. Comparison on the survival rate of Naturally Mated (NM) queen and Artificially Inseminated (AI) queen bees were carried out. The comparison of the oviposition rate on Artificially Inseminated (AI) queen was also done in three study site. The relationship of oviposition rate and mean temperature, mean relative humidity and mean rainfall is carried out in three study sites. SPSS (Statistical Package for Social Science) version 25 was utilized for the statistical tests. The Nonparametric ANOVA test (Kruskal Wallis) was used. 2020
748 Khin Mi Mi Oo MORPHOLOGY AND LIFE CYCLE OF THE PIERID BUTTERFLY SPECIES, DELIAS HYPARETE INDICA WALLACE, 1867 The colour of head is deep black and rounded in shape. Two compound eyes lie on either side of the head. Long coiled proboscis, 13 to 15 mm in length, lies between the eyes that is creamy white colour. Labial palps tapered towards the tip have three segments named basal, middle and terminal with white hairs and 3.3 to 3.5 mm in length. Black antenna, which has 17 to 20 mm in length has 35 to 36 segments. In male the shape of forewing is more or less triangular. The base colour of upperside of forewing is white. Black colour veins are network on it. The hindwing is more or less rounded shaped or oval-shaped. The base colour of upperside is pale orange white. Weak veins are present on it. In the female, the forewing is mostly triangular in shape. The base colour of upper surface of forewing is black and white. The hindwing is mostly oval-shaped. On the upper surface, various colours are present with black coloured veins. Life cycle of the Pierid butterfly, Delias hyparete indica Wallace, 1867 was studied during the study period from June 2017 to May 2018 in Hpa-an University in Kayin State. The mated female mostly laid the eggs on the leaves of Dendrophthoe pentandra (L.) Miq. and Loranthus pentapetalus Roxb. A single batch of eggs laid by the mated female consisted of 31 to 45 eggs. The entire life cycle from egg to the emergence of adult from the pupa lasted for 31 to 38 days. The various developmental stages and the time taken for each stage were recorded and presented with tables and figures. Life span of male was shorter than that of female. 2020
749 Hsu Mon Aung SEASONAL VARIATIONS OF ZOOPLANKTON SPECIES AT THE KANTHARYAR LAKE OF HLAWGA WILDLIFE PARK, MINGALARDON TOWNSHIP, YANGON REGION Seasonal variations of zooplankton species at the Kantharyar Lake of Hlawga Wildlife Park, Mingalardon Township, Yangon Regionwas conducted during June, 2017 to January,2019. A total of 52 zooplankton species of two phyla, four classes, seven orders, 23 families and 36 genera were collected from the study site. The rotifers and copepods were dominant species in the lake. The abundance of zooplankton was highest in the wet season and the lowest in the cold season. Among the species, Brachionus falcatus was the most abundant and Calanoides carinatus was least abundance in study sites. During the study period the maximum number of zooplanktons were recorded in July and the minimum number of zooplankton in January. 2020
750 Myo Myo REVALIDATING THE BIOMETRIC CHARACTERS OF NILE TILAPIA OREOCHROMIS NILOTICUS (LINNAEUS, 1758) IN MEIKTILA Nile tilapia Oreochromis niloticus was carried out to assign the classification of local population relation to their biometric parameters. A total of 265 samples were collected from five markets in Meiktila. Biometric characters of eleven meristic counts and seventeen morphometric traits were generated with Principal Component Analysis (PCA). The result shows the meristic characters of O.niloticus did not change with any increasing in relation to variable morphometric parameters. Analysis of variance (PCA) revealed the two components with 86.85 % (?=14.76) at Taw Ma market, 86.43 % (?=14.69) at Wun Zin market, 84.67 % (?=14.39) at Pauk Chaung market, 83.44 % (?=14.18) at Myo Thit market and three components with 80.66 % (?=13.71) at Myo Ma Central market. Coefficient determination R2 revealed variable significant relationships in total length and other body parts among population, however, with head length relationship showed low correlation in interorbital width (IOW) and mouth length (ML) in all markets. The most striking pattern of hybrid tilapia was found in Pauk Chaung market and Myo Thit market. These pilot surveys strongly suggest the local population of non-indigenous Nile tilapia O.niloticus with the existence of morphological differentiations among population. In addition, the pure population of tilapia species is urgently needed to maintain without hybridizing with other species in Meiktila Environs. 2020
