Master of Science (Entomology), Major Field: Entomology, Department of Entomology. Thesis Advisor: Associate Professor Nantasak Pinkaew, Ph.D. Academic Year 2018 The survey of coleopterans was conducted in Phu Phanang Biodiversity Conservation Area, middle region of Laos, two times in December 2017 and June 2018. This research was aimed to survey and identify of coleopterans to family level. Specimens were collected with window trap and pitfall trap. Both kind of traps were set in two different habitats, teak plantation and disturbed natural forest (which Lagerstroemia sp. is dominant tree). Twelve window traps and 36 pitfall traps were set in each location. The study resulted in collection of 3,691 beetle specimens. They were identified to 38 families 194 morphospecies as follows: Subordr adephaga compose Rhysodidae, Carabidae, Paussidae, Cicindelidae and Dytiscidae. Suborder polyphaga compose Histeridae, Silphidae, Staphylinidae, Scirtidae, Scarabaeidae, Elateridae, Lycidae, Derodontidae, Bostrichidae, Lymexylidae, Cleridae, Nitidulidae, Silvanidae, Laemophloeidae, Phalacridae, Endomychidae, Coccinellidae, Latridiidae, Mycetophagidae, Mordellidae, Tenebrionidae, Alleculidae, Salpingidae, Anthicidae, Cerambycidae, Chrysomelidae, Hispidae, Bruchidae, Anthribidae, Curculionidae, Scolytidae, Platypodidae and Monotomidae. Number of 973 specimens were found in dry season and 2,718 specimens in rainy season. Seven families were found in rainy season less than dry season (10 families) and 21 families were found in both seasons. Differentiation of family number based on kind of trap present as 12 families were captured with window traps more than pitfall traps (3 families) and 23 families were captured in both kinds of trap. For the number of beetle family based on habitat type showed 6 families were found in teak plantation less than in secondary forest (14 families) and 18 families were found in both habitats. Illustrations and the key to family of beetles in Phu Phanang Biodiversity Conservation Area are provided. _________________ _______________________________ ____ / ____ / ____ Student's signature Thesis Advisor's signature D ACKNOWLEDGEM ENTS ACKNOWLEDGEMENTS I would like to express my sincere gratitude to my supervisor Associate Professor Nantasak Pinkaew and Assistant Professor Suksawat Ponpinij for providing invaluable guidance, comments and suggestions throughout my thesis study.
