ABSTRACT

The use of Bacillus ihuringiensis H-14 and B. sphaericus form one of the most important group of biological control agents against mosquito larvae. Data proved that the two fractions of mitochondrial ATPase (Na, K and Mg) in larvae of Cider pipiens and Aedes caspisu Pal, were more sensitive to B. ihuringiensis rather than B. sphaericus. On the other hand, the inhibitoTy action of the two bacterial agents on the ATPase fractions of C. pipiens. There is a positive correlation between post treatment time and ATPase inhibition.

Key Words: Bacillus, Mosquito, ATPase
