Laboratory evaluation of the entomopathogenic fungi Beauveria bassiana and Metarhizium ansiopliae against adults of Dacus ciliatus

The susceptibility of adults of Dacus ciliatus to the fungal isolates of Metarhizium anisopliae (MARD106 and MARD10) and Beauveria bassiana (MARD54 and MARD66) were evaluated under laboratory conditions. The results of the effect of different concentrations of these isolates on the survival rate of adults showed the percentage of survival female which treated with 10 5 ,10 7 and 10 9 spore ml -1 concentrations of MARD106 were 96 , 80 and 32% , respectively, and the survival of male were 100 , 96 and 28%, respectively. The mortality of females at age 1, 4, and 7 days treated with the isolate MARD66, were 100, 62.5 and 35% respectively (r = 0.95), and the mortality of males were 100, 80, and 5%, respectively (r
