Sampling comments: "a study area of 2 500 m2 was selected in each zone, and 16 pit fall traps were placed with 10 m of separation between them... The collections were carried out from February to March 2009 (dry season) and one more August through September 2010 (rainy season), which produced a total of 192 traps" across this sample and the two others; "containers were covered with a plastic dish that held a vial with a lure made from a mixture of oats and honey" and were "opened for 72 h"
