Conteúdo: | A total of 3408 strains of B. thuringiensis were collected from 1448 soil samples from 10 Brazilian states representing 4 geographical regions (Alagoas, Bahia, Ceara, Pernambuco and Sergipe of the Northeast region; Minas Gerais and Sao Paulo from the Southeast region; Parana from the Southern region; and Goias and Mato Grosso do Sul from the Western Central region) covering 96 counties. These strains were evaluated for insecticidal activity against S. frugiperda larvae. Only 62% killed between 81 and 100% of S. frugiperda; 1758 caused no mortality. The highest proportion of efficient strains (larval mortality more than 75%) was found from the total isolated per region in the South Region (16.6%), followed by Western Central (3.1%), Southeast (1.1%) and Northeast Region (0.4%).
