Abstract： Ecologists are often faced with the difficulty of sampling arthropods moving around on land using sampling tools like suction traps. To overcome sampling difficulties associated with such methods, an improved pitfall trap, the cubicsoil pitfall trap, was developed to sample Lycosid spiders in rice fields. This technique proved more accurate and efficient than suction traps. Although we do not dismiss other approaches to sampling arthropods, we suggest that the cubicsoil pitfall trap be accepted as an alternative approach that can potentially achieve a better assessment of species diversity in crop fields.
