<p>The objective of this study was the analysis of the effect of the formicide “Citromax”, formulated with <em>Ateleia glazioviana</em>, in different doses on the control of <em>Acromyrmex lundi</em>, in native field in São Sepé county,  Rio Grande do Sul, Brazil. Four treatments were analyzed, constituted of doses of 5, 10 and 15g of “Citromax” and 10g of “Mirex-S” (sulphluramide 0,3%) in each nest. The statistical design was completely randomized with 10 repetitions, considering each nest as one repetition. The effectiveness was evaluated in the 1^st, 5^th, 10^th, 15^th and 20^th day after treatment application. The obtained results allow to conclude that “Citromax” shows an impact action, because there was a high percentage of control in the first five days. The <em>Acromyrmex lundi</em> control due to “Citromax” formicide was efficient in all the evaluated doses, obtaining a control percentage up to 85%. The influence of net size was not observed in relation to the percentage control.</p>
