Abstract
Species diversity and seasonal dynamics of carabid beetles attracted to a light trap (LT) sited in a tea plantation were compared with those estimated using pitfall traps (PFT) to evaluate efficacy of the LT examination. A total of 1,959 beetles (52 species of 24 genera) were caught in LT from May 25 to October 25, 2010. Species composition of the abundant species caught in LT was more diverse than that estimated using PFT, though Synuchus arcuaticollis, a major species caught in PFT, was not caught in LT. The indices of species diversity were calculated as 0.794 (Simpson’s D) and 2.198 (Shannon-Wiener’s H’), which were higher than those estimated using PFT. Thus, LT has an ability to collect more diverse carabid beetles, but should be supplemented by PFT data for more accurate evaluation of the species diversity of carabid beetles.
