Abstract
Bacillusthuringiensis and Bacillus larvae were tested as biocontrol agents against Ceratitis capitata larvae, Results showed that when larvae of C . capitata fed after five days from egg hatching at any of the tested concentrations (1.25,2.5,5,10) CFU/ml, the highest percentage of mortality occurred with the first three days following application, then the larval mortality started to decrease. The LC50 of the most potent isolates (B. thuringiensis) was 3.5, this was followed by B. larvae 8.)
