Several methods have been used for their control such cortadeirws the use of halogenated, sulfurous and phosphorus compounds. The efficiency of a systematic application of baits against leaf-cutting ants was evaluated in a eucalypus plantation under a minimum cultivation system, in areas owned by Celulose Nipo-Brasileira S.


Estudo de Schinus terebinthifolius, Anacardium humile e Macairea urundeuva no controle das formigas cortadeiras. Treatments consisted of applying a granulated bait with sulfluramide 0. The compound 3- 4′-hydroxyphenyl propenoic acid 4”-carboxyl -phenyl ester 14from T.

However, the continued use of these compounds leads to problems such as environmental contamination and then raising the needed of new strategies to control of leaf-cutting ants.
