http://dx.doi.org/10.5902/1980509816589The search for new leafcutter ant management and control methods have been the aim of several studies over the country, propelled by economic and environmental aspects. The establishment of resistant or less preferred species for the cut can contribute substantially in this subject. This way, the objective of this study was to evaluate the cutting preference between the species Corymbiacitriodora, Eucalyptus benthamii, Eucalyptus camaldulensis, Eucalyptus dunnii, Eucalyptus globulus andEucalyptus urograndisby Acromyrmexambiguus and Acromyrmexcrassispinus in laboratory. Therefore, leafs were offered simultaneously to six colonies of each species in bioassays with chance to choose. However, in the tests without chance to choose, only the least preferred species in the previous test were utilized.  For Acromyrmexcrassispinus, the species Eucalyptus camaldulensis and Eucalyptus urograndiswere the most cutted, besides Corymbiacitriodora, Eucalyptus dunni and Eucalyptus globules were less preferred. Acromyrmexambiguus showed similar preference pattern, adding Eucalyptus benthamiiamong the most preferred one and excluding Eucalyptus dunnii from the least preferred.
