Abstract

The Bacillus sphaericus is an aerobic, Gram-positive, spore-forming bacterium which is widespread in soil and aquatic environments. The potency and specificity of the B. sphaericus toxins make them promising agents for biological control of mosquito pests. The insecticidal toxins of B. sphaericus are both potent and highly specific in their activity against mosquito larvae. The cloning of B. sphaericus toxins into other organisms may provide a useful vector in which the toxin can be applied in the field and further insight into the mechanism of action of the toxins may help in the production of new control agents. There is much potential for further development of the B. sphaericus toxins expressed in new hosts. It should be remembered when developing new host organisms containing Bacillus toxin genes that B. sphaericus and B. thuringiensis israelensis are known to produce more than one type of mosquitocidal protein.
