Abstract：
:Screening for spore-forming bacteria to use against dipterous insects, namelyMusca domestica, Aedes aegypti andCulex pipiens from Egypt, led to two isolates, M1 and S128, being found which were highly toxic to bothAedes andCulex strains. They had calculated international Toxicity Units (ITU) valdes of 17,467 and 20,065 ITU/mg, respectively, as compared with 15,000 ITU/mg forBacillus thuringlensis H-14 IPS-82 Reference Standard. They were taxonomically classilled asBacllus thuringlensis H-14. Their sensitivity to a number ofBacillus phages is also described.
