Ant fauna was surveyed at campus of Ikarashi in Niigata University. Collections were carried out every two weeks from May to November in 2010 at three neighboring sites of the campus, using three different collection methods (hand collection, pitfall traps and honey bait traps). A total of nine species belonging to four subfamilies (Formicinae, Dolichoderinae, Myrmicinae and Ponerinae) and nine genera were collected, and one species (Technomyrmex gibbosus) was recorded for the first time in Niigata Prefecture. Species compositions in the three sites were relatively similar, and the most effective collecting method was the honey bait traps. Ant diversity obtained in our sturdy was far low, compared with that obtained in a preserved,coppice area in Tokamachi city in Niigata Prefecture. Such low diversity may be due to habitat characteristics (possibly, low plant species richness). Our results add a further evidence that ants are reliable ecological indicators for evaluating environmental conditions. Ants are among the most suitable groups of animals for community characterization, since they are diverse, very abundant and occur virtually in all ecosystems. We thus propose that monitoring ant fauna is a good tool to apply environmental education.
