Abstract
Five new high-toxicity mosquitocidal strains of Bacillus sphaericus we re isolated in Singapore. They all belong to phage group 8 and have bi nary toxin (51.4- plus 41.9-kDa) genes located on the chromosome but l ack a 100-kDa-toxin gene. These strains of B. sphaericus constitute a new subgroup, as only two weakly toxic strains in phage group 8 have p reviously been described and all the known high-toxicity strains have both binary toxin and 100-kDa-toxin genes.
