Abstract
Entomopathogenic bacteria isolated from Simulium larvae and adults from bre eding sites in the states of Sio Paulo and Rio de Janeiro, Brazil, were ide ntified as 18 strains of Bacillus thuringiensis and one of B. sphaericus. M ost of these strains were serotyped according to their flagellar antigens. However, nine of the B. thuringiensis samples, could not be serotyped and w ere designated as "autoagglutinating"; they were also shown to be toxic in preliminary tests against Aedes aegypti larvae. Additionally, B. sphaericus was also shown to be toxic towards Culex quinquefasciatus larvae.
