Bacillus Thuringiensis: Different Targets And Interactions

In the microbial control of pests, the entomopathogen Bacillus thuringiensis offers the best biological alternative to chemical insecticides, either alone or in combination with other methods of field control, and is also a source of genes for the genetic engineering of plants. In this work, aspects related to new targets of this bacterium are described such as: Acromyrmex spp.; Nasutitermes ehrhardt; Euschistus heros; Oryzophagus oryzae; Blatella germanica; Pyricularia grisea, Rhizoctonia solani, Fusarium oxysporum; Fusarium solani and Meloidogyne spp. Also discussed are the interactions of Bacillus thuringiensis and B. subtilis with other biological control agents: Purpureocillium lilacinus; Campoletis flavicincta; Nuclear Polyhedrosis Virus; plant extracts and essential oils from medicinal plants. Data from our research group of Microbiology and Toxicology in Agroecosystems (MToxAgro/CNPq), as well as collaborating researchers of some public and private institutions of Brazil will be presented.
