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.

Several methods have been used for their control such as the use of halogenated, sulfurous and phosphorus compounds. AcromyrmexMycocepurusSericomyrmexchemical control, leaf-cutting ants.

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. Some features of this site may not work without it. Revista Yvyraretan. Additionally, the limonoid cedrelone, from T. Services on Demand Journal. Autor Cazal, Cristiane de Melo.

O trabalho foi conduzido nos reflorestamentos de eucalipto da Celulose Nipo-Brasileira S. Systematic control of leaf-cutting ants in areas with eucalyptus stands under minimum cultivation system. 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. How to firmigas this article. Entretanto, a literatura cita que, potencialmente, M. The efficiency of this granulated bait, applied in a systematic manner, varied with the method and species of leaf-cutting ants.

Controle de Acromyrmex laticeps nigrosetosus Hymenoptera: Control de Acromyrmex crassipinus Hymenoptera: Polymeric nanoparticles and bioassay-guided phytochemical investigation of Trichilia elegans e Trichilia catigua Meliaceae for the control of leaf-cutting ants Leaf-cutting ants are known as severe agricultural pests. Formicidae na dosagem de iscas granuladas por olheiro ativo.

Controle de Acromyrmex subterraneus molestans Santschi Hymenoptera: Formicidae por hectare, respectivamente. The compound 3- 4′-hydroxyphenyl propenoic acid 4”-carboxyl -phenyl ester 14from T.


Formicidae en areas de rebrote de Eucalyptus grandis com un sebo a base de sulfluramida. Higher efficiency was obtained for A. Resumo Leaf-cutting ants are known by their strong power of to pulling down several vegetable crops and to cause tormigas lost to ccortadeiras agriculture.

Phytochemical investigations from dw extracts and fractions have allowed to isolate 23 compounds 3 newincluding sterols, coumarins, phenolic compounds, oxazol derivative, flavonoids and limonoids.

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 pests.

A cluster analysis method cogtadeiras grouping means in the analysis of variance. Estudo de Schinus terebinthifolius, Anacardium humile e Macairea urundeuva no controle das formigas cortadeiras.

Fogmigas compounds have been proposed for their control such as organophosphorus, pyrethroids and sulfluramid insecticides. 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.
