Autor(es): Panbangred W,Pantuwatana S,Bhumiratana A
Resumo: Among six strains of Bacillus thuringiensis and five other species of Bacillus, only two strains of B. thuringiensis, strains HD-1 and BA-068, were toxic to Aedes aegypti larvae within 24 hr. The LC50s were 5.6 × 104 and 2.4 × 105 spores/ml for strains HD-1 and BA-068, respectively. The toxic factor(s) was heat sensitive and ? ray resistant and preliminary evidences indicated that it was associated with the crystalline body of B. thuringiensis.
