Abstract

In terms of environmental impact and facing problem of contamination by agrochemicals and difficulties related to their identification by chemical analysis, additional information, such as provided by biological assays, have been increasingly used to estimate the effects of pollutants on ecosystems and the various groups of organisms. The organisms used as bioindicators require certain environmental and ecological characteristics to develop and therefore may reflect the state of repair and / or degradation of a place. Among these organisms, ants represent a group with great potential for use in environmental monitoring programs. Faced with this problem, this project aims to evaluate the effects of pesticides and other environmental contaminants used in the culture of cane sugar in cell death ant species Atta leaf cutter, through the analysis of the viability of cells of the brain, digestive tract and Malpighian tubules, as well as the assessment of the possible changes that may occur in the structure of the cytoskeleton and the nucleus of these cells through the application of Confocal Microscopy techniques.
