Conteúdo: | The aim of this work was to evaluate the influence of production systems involving the eucalyptus culture on infestation as well as the necessity of controlling its defoliator Glena unipennaria in order to qualify how sustainable integrated production systems are. Adult infestation was evaluated in the following systems: (1) eucalyptus monoculture, (2) agroforestry (grains integrated with eucalyptus), (3) silvopastoral (palisade grass integrated with eucalyptus) and (4) agrosilvopastoral (palisade grass cultivated after grains, both integrated with eucalyptus) production systems. Results showed that adult infestations in integrated systems are significantly lower and different from eucalyptus in monoculture. Consequently, the defoliation rate by caterpillars occurred mainly in monoculture, with greater intensity in the interior of the plot compared to the trees in the edge, suggesting that solar irradiance influences the pest establishment in the field. Besides that, in eucalyptus monoculture, it was necessary to use two sprays of Bacillus thuringiensis-based insecticides at 1 L ha-1 with a 15-day interval, while in the integrated systems this was not needed due to the low damage caused.
