Phytonematodes are a threat to agricultural productivity and food security for the world population. Management strategies for these plant pathogens are undergoing a reformulation, where biological control tools are proving to be a promising market. In addition to this, the development of techniques for detecting and identifying these pathogens in crops is a constant need. Therefore, this research sought to find new organisms for use in the biological control of phytonematodes, as well as new techniques for identifying these pathogens. In Chapter 1 of this Thesis, I discuss the relevance of phytonematodes in agricultural production worldwide and some of the main species of these pathogens. I also present the potential of the microbiota associated with stingless bee larval food in the biological control of pathogens and in other biotechnological processes. In Chapter 2, I present the article “Screening of microorganisms isolated from stingless bee’s larval food in the biocontrol of Meloidogyne incognita”, in the submission for publication format. This work presents a screening and identification of microorganisms associated with the larval food of stingless bees that have a nematicidal effect on the Meloidogyne incognita species. In Chapter 3, I present the article “Differentiation of Heterodera glycines races by metabolomics” in the submission for publication format. This work addresses the use of metabolomics tools in the identification of races of the species Heterodera glycines, with the aim of facilitating the identification of this pathogen in crops as well as assisting in decision-making in management strategies.
