%X The objective of this study was to assess if larvae of Phylloicus spp. show any preference for leaves with or without microorganisms when building cases. Two experiments were realized at municipality of Presidente Figueiredo (Amazonas 每 Brazil), containing leaves treated with Hydrogen peroxide (H2O2), a compost that has an antimicrobial action, and another one with untreated leaves. In the first were observed the case-building by larvae of Phylloicus spp. and in the second was tested the preference by treated or untreated leaves. The larvae were monitored during 24 hours and to statistical analysis was used the t-test. Were not observed significant differences in the number of discs used by the larvae in the first experiment (p=0.24; t=-0.73) and no preference by type of leaf in the second experiment (p=0.41; t=0.23). Therefore, we do not recommend the use of hydrogen peroxide in studies that aim to eliminate microorganisms from decomposing leaves.

Dois experimentos foram realizados no munic赤pio de Presidente Figueiredo (Amazonas 每 Brasil), contendo folhas tratadas com per車xido de hidrog那nio (H2O2), composto que possui a  o antimicrobiana, e folhas n o tratadas. No primeiro observaram-se a constru  o de abrigos pelas larvas de Phylloicus spp. e no segundo testou-se a prefer那ncia por folhas tratadas ou n o tratadas. As larvas foram monitoradas durante 24 horas e para a an芍lise estat赤stica foi utilizado o teste-t. N o foram observadas diferen as significativas no n迆mero de discos usados pelas larvas no primeiro experimento (p=0,24; t=-0,73) e nem na prefer那ncia pelo tipo de folha no segundo experimento (p=0,41; t=0,23). Portanto, n o recomendamos o uso do per車xido de hidrog那nio em estudos realizados em laborat車rio que visem 角 elimina  o de micro-organismos de folhas em decomposi  o.
