This work was developed in two stages: 1st stage, to evaluate the influence of different nutrients on the loading preferably leaf discs obtained from Eucalyptus camaldulensis Dehnh leaves. by Acromyrmex rugosus and acromyrmex balzani; 2nd step, identifying the preference charging leaf discs obtained from leaves of Eucalyptus species spp. and Corymbia citriodora, used in reforestation in Mato Grosso. In the first step it was compared to the effect of the treatments on the two species of Acromyrmex spp. in nests located in urban and rural area of the municipality of Varzea Grande, MT, in rainy periods from November to April and dry from May to October. It was found that in the period from November to April, was the largest shipment of leaf discs compared to the months from May to October of the same year, but there was no statistical difference between the periods. The leaf disks from the treatment no phosphorus was carried by ants as followed in decreasing order by treatments without potassium, calcium, water, nitrogen and treatments that less contributed to the choice of transport for disks were Magnesium, Sulphur and Complete. Both Acromyrmex species had the same leaf discs transport preferences, however, A. Balzani showed a lower rate of transport than A. rugosus. In the 2nd stage of the work was compared the effect of treatments on Acromyrmex spp. using nests located in urban and rural area of the municipality of Várzea Grande. Discs from leaves of the seminal seedlings of Eucalyptus urophylla were the most transported and followed by the seminal seedlings of hybrid urograndis and seminal seedlings Corymbia citriodora. The discs were transported least those of the hybrid clones urograndis "GG100", followed by hybrid urograndis "H13" and "I144" and urocan vm01 hybrid clones.
