Resumo Leaf-cutting ants are known by their strong power of to pulling down several vegetable crops and to cause economic lost to the clrtadeiras. Finalmente, acredita-se que M.


The efficiency of this granulated bait, applied in a systematic manner, varied with the method and species of leaf-cutting ants. Formicidae por hectare, respectivamente. Several methods have been used for their control such as the use of halogenated, sulfurous and phosphorus compounds.

Higher efficiency was obtained for A. Besides these results, this study contributed to a project that has been developed by the Natural Product Laboratory at UFSCar, which aims to evaluated the biological activity of several metal complexes with different metals and flavonoids to the control of several agriculture formigzs.

In this context, this work presents a phytochemical study of the species Schinus terebinthifolius, Anacardium humile e Macairea urundeuva and the insecticide and fungicide potential of the crude extracts, fractions and isolated compounds against the leaf-cutting ants, Atta sexdens rubropilosa, and its symbiotic fungus, Leucoagaricus gongylophorus.

From the biological assays with leaf-cutting ants, it was found that several extracts showed insecticidal activity as a result of the synergistic effect of their chemical composition.

Um estudo de caso: For both species A. Some features of this site may not work without it. These natural insecticides were nanoencapsulated for the first time and the results observed here showed a better activity, more water dispersivity and stabilization of nanoparticles if compared to free compounds. The solvent displacement technique adopted here showed to be very efficient for the preparation of nanoparticle formulations containing either xanthyletin or rauianin.
