        Myanmar is located in the south-east Asia peninsular and it is flanked by five neighboring states: Bangladesh, India, China, Laos and Thailand. It is located 10~22 degree north latitude, to 92~101 degrees east longitude. Myanmar has a tropical climate with three seasons in Myanmar. Hot season (March through April), rainy season (May through October) and the cool season (November through February). The coastal regions can get very hot and humid, especially before the rainy season. Myanmar has a monsoon season from May to October when there are heavy rains and often flooding. The investigation was carried out during the dry season(2013) in Nat Ma Taung National Park and Popa Mountain Park. Popa Mountain Park is located in Kyawpadaung Township, Myinchan district, Mandaly Division. The area is 49.63 square miles. Its coordinates are 29°31'60" N and 27°43'60" E. Nat Ma Taung National Park, Myanmar treasure is in Mindut District of Chin State and its area of 279 square miles. It is the third highest mountain in Myanmar with the height of 10,500 feet. Its coordinates are 21°14'00" N and 93°54'00" E. As the result, butterflies(Lepidoptera) collected in the two regions were about 60 species of 7 familys. Collecting dates, expedition activities, photo of main specimen and information of Myanmar were provided.

        Myanmar is located in the Southeastern region of Asia. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. The bordering countries are China on the northern side, Thailand and Laos on the eastern region, Bangladesh on the western side and India on the northwestern region. Myanmar has a total area of 678,500 square kilometers (262,000 sq mi). The rainy season exists primarily during the months between June and September. Whiledry season stays during the months between December and April. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted four times for three years. Among them we explored three area including Popa Mountain, Alaungdaw Kathapa National Park and Nat Ma Taung National Park[Popa Mountain(8.7~8.17, 2011; 7.24~8.3 2012; 2.18~2.28 2013), Alaungdaw Kathapa National Park(2.2~2.9, 2012) and Nat Ma Taung National Park(2.18~2.28 2013)]. Collecting methods was sweeping net, lignt trap, burket trap, pitfall trap with other method, and collected especially mainly Coleoptera and Lepidoptera. As the result, totally about 30 families in Coleoptera and 7 families in Lepidoptera were collected, among them Carabidae and Nymphalidae was revealed most diversity species.

        Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic Of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.9 in) of rain annually. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted two times in two years. First, collecting expeditions of insect were conducted in Popa resort, Myanmar from Aug. 7, 2011 to Aug. 17, 2011. Second, collecting expeditions of Insect were conducted in Alaungdaw Kathapa National Park (AK National Park), Myanmar from Feb. 2, 2012 to Feb. 9, 2012. As a Protected area of the Forest department, these areas were almost natural conservation field and limited to collection actions. Usually on day time, butterflies collected by sweeping net, like various plants, they shows high diversity. Some Papilionidae species are difficult to meet because they fly very high and fast, usually they visit to top of trees. Up to now, 60 species of 7 families were confirmed. Materials are expected more than 100 species belonging to 10 families but it was difficult to identification because of lack of references of this areas. Among them, with rare species, manifold butterflies are provided with photos, ecological notes and activities of Myanmar.

It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.6 in) of rain annually. Annual rainfall in the delta region is approximately 2,500 mm (98.4 in), while average annual rainfall in the Dry Zone, which is located in central Myanmar, is less than 1,000 mm (39.4 in). The average annual temperature is about 27℃(about 80℉). This expedition was conducted two times in two years (8.7~8.17, 2011; 2.2~2.9, 2012). As protected forest from government, these areas were almost natural conservation field. Pitfall trap, sweeping method, light trap and searching etc. were used to collect insect. As the result, totally about 30 families in Coleoptera was collected, among them Oodes species of Carabidae was highest number and species in Chrysomelidae, Cicindelodae, Scarabaeidae and Dynastidae etc., were collected. It was difficult to identification because of lack of references of this areas. Maybe lots of new or new recorded species will discover from Myanmar. Among Coleoptera species, with big sized beetles as the central figure, photos for species of dominant, rare, nominated species of new or new recorded were introduced, and also collecting sites and activities were presented.

        Cambodia covers an area of 181,035 sq km among them, forests cover 53 percent. As a tropical monsoon climate, average annual rainfall is about 1,400 mm(about 55 in) on the central plain and increases to as much as 3,800 mm (150 in) in the mountains and along the coast. The average annual temperature is about 27°C (about 80°F). There are many wildlife diversity in Cambodia, but regulated or unregulated logging and mining have diminished the country's wildlife rapidly. This expedition was conducted three times in 2009 (7.2-7.11, 10.16-22, 12.25-12.30). Central Cadamon Protected Forest (N 11° 41' 13" E 103° 26' 31.3") and Seima Biodiversity Conservation Area (N 12° 08' 20.8", E 106° 55' 2.7") were main area surveyed by pitfall trap, light trap and sweeping etc. As the result, totally 611 individuals of 11 families in Coleoptera was collected, among them Gonocephalumspecies of Tenebrionidae was highest number and species in Melonthidae, Chrysomelidae and Dynastidae etc., were collected, specially kind of Hydrophilidae species from wetland was surved in the expedition.

        The technology of direct-seeding in rice cultivation is an innovation mainly induced by factors in market economy and is rapidly diffused among individual farmhouses. Because the effect of technology can be affected by many factors under various farming circumstances, the impact and stability of the direct-seeding technology compared with transplanting was analyzed under various topographical regions. Yield in direct-seeding was higher in plains, although the farm size producing higher yield was quite different depending on the topographical regions. In the direct-seeding cultivation of rice, man-labor hours was reduced by about 38 percent and the reduction rate showed little difference among topographical regions. Fertilizer was used about 11 percent more but the increase rate varied from 3 to 17 percent depending on regions with higher rates in plains. Application of agricultural chemicals was also increased about 9 percent in direct-seeding, but the increase rate was as high as 12 percent in suburbs. More fertilizer and agricultural chemicals were used in direct-seeding cultivation by farmhouses implementing both direct-seeding and transplanting than by those implementing direct-seeding only. Use of more fertilizers and agricultural chemicals in direct-seeding in all regions may indicate its technical instability. Major problems causing the technical instability of direct-seeding cultivation should be solved by comprehensive research considering various farming circumstances such as topographical features rather than just a top-down style research and extension.
