Extract

Pitfall trapping is a widely used sampling method for biodiversity-related research of ground-dwelling arthropods. The trap is a container, usually with a preservative, that is sunk into the ground to collect arthropods which happen upon the trap perimeter and fall in (Lemieux and Lindgren 1999; Work et al. 2002). Two types receive the most use: deep circular pitfall traps and shallow rectangular pan traps (Marshall et al. 2001). The preserving fluid can influence trap efficacy (Deville and Wheeler 1998). Our objectives were to compare the efficiency of pitfall and pan traps with and without detergent in the preserving fluid (Marshall et al. 1994), using carabid beetles (Coleoptera: Carabidae) and spiders (Araneae) as focal taxa.
