The use of microorganisms to control insect pests started to be developed when the insecticidal properties of the bacterium Bacillus thuringiensis was discovered in the last century. B. thuringiensis comprises a group of aerobic Gram positive spoor-forming bacteria that produce a crystalline inclusion toxic against some insect of different orders. Insecticidal proteins from B. thuringiensis have been used in sprays formulations and its genes have been incorporated into several major crops where they provide a model for genetic engineering in agriculture. However, the need to find new proteins with a greater spectrum of toxicity as well as to delay the development of resistance to toxins by some insects suggest the need to search new bacteria or their derivatives with insecticidal properties. In this context, the general objectives of this research is the isolation and characterization of strains of native toxic nutritional and or symbionts bacteria that can be used to develop biological products to control insect populations of regional importance in agriculture and human an animal health.
