Abstract

The indiscriminate use of synthetic pesticides has caused concern in the scientific community due to adverse effects in man and in the environment. Aware of this problem, governments of many countries have banned the use of some substances, forcing the development of alternatives with the same efficiency and environmentally safer. Although it has been banned in many countries, the insecticide sulfluramid is still used in Brazil for the control of ants, an agriculture pest. As an effective alternative to the use of sulfluramid, researchers from UNESP and UFSCar developed a Metallo-Insecticide system, whose formula is a natural product complexed with a metal. However, for certification that it is environmentally safe, ecotoxicological tests are necessary. In this sense, this project proposes to examine the toxic potential of this Metallo-insecticide system to non-target organisms through the following tests: reproduction and avoidance test, using the species Folsomia candida (Collembola) and Eisenia andrei (Annelida); mutagenicity, genotoxicity and cytotoxicity tests, using Allium cepa and Tradescantia pallida and a representative of the soil fauna, the millipede Rhinocricus padbergi.
