Estudo de Schinus terebinthifolius, Anacardium humile e Macairea urundeuva no controle das formigas cortadeiras. Metadata Mostrar registro completo. Control de Acromyrmex crassipinus Hymenoptera: Systematic control of leaf-cutting ants in areas with eucalyptus stands under minimum cultivation system.
Fatores que dificultam o controle das formigas cortadeiras
Besides these results, this study contributed to a project that has ckrtadeiras 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, non-target animals and environmental contamination are common problems and therefore new strategies to control these pests have been requested. Controle de Acromyrmex laticeps nigrosetosus Hymenoptera: Formigas cortadeiras e o seu controle.

Formicidae na dosagem de iscas granuladas por olheiro ativo. 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.
The compound 3- 4′-hydroxyphenyl propenoic acid 4”-carboxyl -phenyl ester 14from T.

Um estudo de caso: 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.
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. Some features of this site may not work without it. Autor Cazal, Cristiane de Melo.
Phytochemical investigations from active extracts and fractions have allowed to isolate 23 compounds 3 newincluding sterols, coumarins, phenolic compounds, oxazol derivative, flavonoids and limonoids. Revista Yvyraretan. A cluster analysis method for grouping means in the analysis of variance.
Finalmente, acredita-se que M. For both species A. Mortality of colonies of leaf-cutting ants was evaluated 30 days after bait application. The solvent displacement technique adopted here showed to be very efficient for the preparation of nanoparticle formulations containing either xanthyletin or rauianin. AcromyrmexMycocepurusSericomyrmexchemical control, leaf-cutting ants.
Treatments consisted of applying a granulated bait with sulfluramide 0. The 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.
Several compounds have been proposed for their control such as organophosphorus, pyrethroids and sulfluramid insecticides. The elagic acid isolated from M. O trabalho foi conduzido nos reflorestamentos de formigass da Celulose Nipo-Brasileira S.
Several methods have been used for their control such as the use of halogenated, sulfurous and phosphorus compounds.
