A cluster analysis method for grouping means in the analysis of variance.

Finalmente, acredita-se que M. Controle de Acromyrmex laticeps nigrosetosus Hymenoptera: O trabalho foi conduzido nos reflorestamentos de eucalipto da Celulose Nipo-Brasileira S.

Formicidae en areas de rebrote de Eucalyptus grandis com un sebo a base de sulfluramida. Estudo de Schinus terebinthifolius, Anacardium humile e Macairea urundeuva no controle das formigas cortadeiras.

Treatments consisted of applying a granulated bait with sulfluramide 0. JavaScript is disabled for your browser. 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. The efficiency of ee systematic application of baits against leaf-cutting ants was for,igas in a eucalypus plantation under a minimum cultivation system, in areas owned by Celulose Nipo-Brasileira S.

Polymeric nanoparticles and bioassay-guided phytochemical investigation of Trichilia elegans e Trichilia catigua Meliaceae for the control of fprmigas ants Leaf-cutting ants are known as severe agricultural pests. Formigas cortadeiras e o seu controle. Systematic control of leaf-cutting ants in areas with eucalyptus stands under minimum cultivation system.

Several compounds have been proposed for their control such as organophosphorus, pyrethroids and sulfluramid insecticides. Efeito do tamanho de formigueiros de Atta sexdens rubropilosa Forel, Hymenoptera: Some features of this site may not work without it.

Mortality of colonies of leaf-cutting ants was evaluated 30 days after bait application. 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, Dee gongylophorus. The solvent displacement technique adopted here showed to be very efficient for the preparation of nanoparticle formulations containing either xanthyletin or rauianin.
