H. B.  aMolecular characterization of Bacillus thuringiensis strains to control Spodoptera eridania (Cramer) (LepidopterabNoctuidae) population.h[electronic resource]  c2020  aThe main objective of this study was to characterize the toxicity and genetic divergence of 18 Bacillus thuringiensis strains in the biological control of Spodoptera eridania . Bacterial suspensions were added to the S. eridania diet. Half of the selected B. thuringiensis strains caused high mortality seven days after infection. The genetic divergence of B. thuringiensis strains was assessed based on Enterobacterial Repetitive Intergenic Consensus (ERIC) and Repetitive Extragenic Palindromic (REP) sequences, and five phylogenetic groups were formed. Despite their genetic diversity B. thuringiensis strains did not show any correlation between the collection sites and toxicity to larvae. Some B. thuringiensis strains are highly toxic to S. eridania, thus highlighting the potential of their endotoxins as biopesticides.  aBactéria  aControle Biológico  aInseto  aPraga de Planta  aTipagem molecular  aToxicidade1 aLIVRAMENTO, K.
