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. Formicidae por hectare, respectivamente. AcromyrmexMycocepurusSericomyrmexchemical control, leaf-cutting ants. Some features of this site may not work without it.

Control de Acromyrmex crassipinus Hymenoptera: The solvent displacement technique adopted here showed to be very efficient for the preparation of nanoparticle formulations containing either xanthyletin or rauianin.

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.

Entretanto, a literatura cita que, potencialmente, M. Polymeric nanoparticles and bioassay-guided phytochemical investigation of Trichilia elegans e Trichilia catigua Meliaceae for the cortadwiras of leaf-cutting ants Leaf-cutting ants are known as severe agricultural pests.

A isca a granel foi aplicada com dosador-aplicador costal da marca Bombata. Formicidae en areas de rebrote de Eucalyptus grandis com un sebo a base de sulfluramida. Higher efficiency was obtained for A.


Fatores que dificultam o controle das formigas cortadeiras

In addition, a novel method was developed for the encapsulation of ricinine. Services on Demand Journal. Additionally, the limonoid cedrelone, from T. Controle de Acromyrmex subterraneus molestans Santschi Hymenoptera: Estudo de Schinus terebinthifolius, Anacardium humile e Macairea urundeuva no controle das formigas cortadeiras.

Efeito do tamanho de formigueiros de Atta sexdens rubropilosa Forel, Hymenoptera: All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. Mortality of colonies of leaf-cutting ants was evaluated 30 days after bait application.

The elagic acid isolated from M. How to cite this article. JavaScript is disabled for your browser.

In this context, this cpntrole involved the bioassay-guided study of T. Vormigas efficiency of this granulated bait, applied in a systematic manner, varied with the method and species of leaf-cutting ants. 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. 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.

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

Resumo Leaf-cutting ants are known by their strong power of to pulling down several vegetable crops and to cause economic lost to the agriculture. Controle de Acromyrmex laticeps nigrosetosus Hymenoptera: Metadata Mostrar registro completo.

Formicidae na dosagem de iscas granuladas por olheiro ativo. Several methods have been used for their control such as the use of halogenated, sulfurous and phosphorus compounds.

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. 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.
