Site length: 200.000
Sampling methods: line transect, pitfall traps
Sample size: 17721
Years: 2005, 2006, 2007
Days: 308
Nets or traps: 48

Sampling comments: "Insects were sampled with pitfall traps, each consisting of a plastic cup, 8 cm diam and 14 cm high. Two parallel 200-m transects separated 10 m apart were installed in each experimental area. Each transect spanned the habitat interface with 100 m in the forest fragment and 100 m in the field devoted to the production of soybean and corn... 48 traps spaced 10 m apart were set in each area with 24 in the forest fragment and 24 in the cultured area... samples were taken... from 9 Apr 2005 to 26 Apr 2007, totalling 44 sampling dates. The traps remained installed in the field for 1 wk"
