Years: 2008

Days: 7

Sampling comments: "One line-transect within the study site was surveyed monthly during one year. The transect consisted of 20 sampling points separated by 10m for a total extent of 200m. At each sampling point, a polyvinyl chloride (PVC) tube (14cm deep, 12.2cm diameter) was placed in the soil and remained there for the whole sampling period (August 2008-August 2009). The PVC tubes served as sleeves to house the 20 pitfall traps (13cm deep, 12cm diameter)... Sampling was undertaken once a month... The pitfall traps were partially filled with a mixture of 90% ethanol (70%) and monoethylene glycol (30%) and operated for seven days"
