SUMMARY:

Macrofauna and mesofauna are organisms that are very sensitive to biotic and abiotic agents, reacting quickly to changes that may alter the structures of the niche in which they are inserted, being widely used as bioindicators. The simple presence, absence or discrepancy in the abundance of these organisms in a natural or monoculture area can be a strong indication of an imbalance. In eucalyptus cultivation, the richness or abundance of ants, termites, yellow eucalyptus beetle and tanned stink bug indicate that the crop may be suffering economic damage, being considered pests. However, it problematizes the existence of an interdependence that results in negative multifaceted effects, positively hypothesizing. In view of the above, this project aims to identify and understand the influence of the Crop-Livestock-Forest Integration System (CLFS) on the insect community and soil meso- and macrofauna, in the municipality of Chã Preta, Alagoas. In order to better understand the object of study and achieve the objectives, it is intended to carry out quantitative and qualitative field research, for three years, with non-probabilistic convenience sampling in four distinct areas, namely: forest remnant area; extensive pasture area; pasture area with eucalyptus plantation; and area of corn-pasture succession, with eucalyptus. Pest assessment will be done by collecting insects and/or observing their damage, using the Davis scale, Bianco scale, etc. To collect macrofauna, the standard method recommended by the Tropical Soil Biology and Fertility Program (TSBF) of the United Nations Educational Program will be used, as well as by the Scientific and Cultural Organization (UNESCO). For soil mesofauna, soil and litter will be removed using metal rings with a diameter of 55 mm, that is, 2.17 inches by 30 mm in height, each ring will be labeled with pertinent information about the area of study and will remain for a period of 96 hours to extract mesofauna in the Berlese-Tullglen extractor. In all areas, chemical (pH, P, K, Na, Fe, Cu, Zn, Mn, Ca, Mg and Al, H + Al and C.O.T) and physical parameters (granulometry) will be analyzed. All data collected in the four sampled areas will be tabulated, organized and submitted to the STATISTICA 13.0 software with a significance index of 0.05, obtaining the Shannon diversity and Pielou Uniformity indices. At the end of the study, the aim is to obtain robust data on the influence of the system on the main pests occurring, as well as on soil biota.
