Habitat comments: "The experimental area consisted of a 48-ha fragment of semideciduous forest, and an 88.6-ha field that for the past 10 yr had been devoted to a no-till system of producing a summer crop of soybean Glycine max and a winter crop of corn Zea mays" (P. 502)

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"
