Journal of the Faculty of Agriculture SHINSHU UNIVERSITY Vol.41 No.1・2 (2005) 31 Leaf Beetles (Coleoptera;Chrysomelidae)in the Campus and Agricultural Research Stations of Chiang Mai University,Thailand Shinya UMEMURA, Jiraporn TAYUTIVUTUKULand Hiroshi NAKAMURA Graduate School of Agriculture,Shinshu University Department of Entomology,Faculty of Agriculture,Chiang Mai University,Chiang Mai,50200,Thailand Education and Research Center of Alpine Field Science,Faculty of Agriculture,Shinshu University Summary. Qualitative surveys of leaf beetles were conducted at 5 survey sites (Chiang Mai Univer- sity,Mae Hia Staion,Chang Kien Station,Nong Hoi Station,Suburb of Chiang Mai City)in Chiang Mai,Thailand using sweeping and beating methods from October 19to October 30,2003.A total of 24 species of 8 subfamilies was collected from five survey sites;11 species,3 species,2 species,11 species, 4 species from Chiang Mai University, Mae Hia Station, Chang Kien Station, Nong Hoi Station,Suburb of Chiang Mai City,respectively.In these species,Lema coomani,Aulacophora indica, Aulacophora lewisii, Monolepta pallidula,Chaetocnema (Chaetocnema) concinnicollis,Altica cyanea and Aspidomorpha furcata are also distributed in Japan.Based on these data,inventory of leaf beetle was made. Key word:leaf beetles;inventory;Chiang Mai University;Thailand forest canopy have been made as part of this Introduction project. Leaf beetles belong to family Chrysomelidae, At present, the conservation of biodiversity is order Coleoptera in Insecta. Fifty thousand one of the most important ecological problems species of leaf beetles distribute throughout the throughout the world.In relation to this problem, world.Larvae and adults of this beetle eat specific the qualitative surveys or making inventory of plants and mobility of leaf beetle adults is small. insects have become to be an important study,for So inventories of leaf beetle can be useful infor- they are regarded as the basic studies to reveal mation to evaluate the change of the environment. and conserve biodiversity.In case the ecological But there are few studies which investigate leaf information of an insect group is well known like beetle fauna in South East Asia because butterflies,it is possible to estimate the impact of identification of these beetles is very difficult. environmental change against the insect group by In this study, we conducted a survey of leaf tracing the inventories of the group for several beetle fauna in Chiang Mai,Thailand as a prepar- years.
