Abstract: The objective of this work was to survey soil ants in Bt and non-Bt maize (Zea mays) crops, and to compare their effect on the soil ant community. Nine pitfall traps, 10 m apart, were installed in a central area (900 m2) of each of the following treatments (2,500 m2): conventional maize; maize modified with the Cry1F, Cry1Ab, and Vip3A proteins; and a native vegetation area. Fortnightly collections were conducted during four periods (complete producing cycles) of the crop, from 2011 to 2013. The number of ant species varied from 25 in Bt maize (Vip 3A) to 58 in Bt maize (Cry 1F). The treatment with conventional maize showed the highest Shannon-Wiener diversity index (H’ = 2.60). Jaccard’s index showed that there is dissimilarity between the...
