The activities of soil insects and litter insects play an important role in ecosystem in particular, proceeding nutrient cycling. The objectives of this study were to investigate diversity and the role of soil insects and litter insects in three different forests: dry dipterocarp forest (DDF), dry evergreen forest (DEF) and ecotone (ECO) during rainy season, winter and summer. Furthermore, physical and chemical parameters of the soil in each forest were investigated. The experiment was conducted at Sakaerat Environmental Research Station, Nakhon Ratchasima province during the period of January 2005 to December 2005 and June 2007 to July 2008. Samples were collected using hand collection and litter bag method. The result showed that there were 6 orders and 10 families of soil insects. Hymenoptera was the most commonly found in the year 2005. Isoptera was the most discovered on the soil surface at DDF and Hymenoptera was the most found in the subsoil at ECO in the year 2007-2008. Moreover, soil insects on the soil surface were higher than the subsoil insects. The rate of decomposition of soil surface and subsoil of the ECO in the summer had the highest at 61.00
