This study was developed in urograndis eucalypt hibrid (Eucalyptus urophylla X Eucalyptus grandis) plantation belonging to Jari Celulose S.A., in Monte Dourado, Pará State, Brazil, from July 1993 to January 1994. Mirex-S (sulfluramid 0.3%) bait at the dosages of 6, 8 and 10 grams was compared to 10 grams of a dodecachlor (0.45%) bait per square meter of ant hill, against Atta cephalotes (Hymenoptera: Formicidae). At the dosages of 6, 8 and 10 grams the Mirex-S bait showed 72.7; 83.3 and 91.67% of nest control compared to 87.5% for the dodecachlor bait. Therefore, Mirex-S bait at 8 and 10 grams per square meter of ant hill can replace the dodecachlor baits for A. cephalotes control.
