The efficacy of Beauveria bassiana, Metarhizium anisopliae and their mixture to control last instar (prepupae) Mediterranean fruit fly, Ceratitis capitata larvae in the soil using different volumes of spore suspension concentrations were investigated under lab condition. M. anisopliae revealed higher mortality rate than B. bassiana reaching 73.80% at 1×109concentration of volume 20ml/100g. However, the mixture of M. anisopliae and B. bassiana expressed the highest mortality rate among Ceratitis capitata larvae reaching 96.60 % at the concentration 1×109 and 20ml volume with lowest LC50 of 234x 107. The mortality rates of Metarhizium anisopliae fungus were 40.6 and 61.3% at 1×106 and 1×109, respectively. According to the study outcome, fungal mixture 1×109 concentration can be applied in the field with 200 ml /m3 soil according to the volume transformation.
