Laboratory bioassays at 27 ± 2°C, 90 ± 5% RH and 12:12 h L:D were used to determine the susceptibility of Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) a parasitoid of the coffee berry borer Hypothenemus hampei, to 9 strains of the entomopathogenic fungus Beauveria bassiana and 5 strains of Metarhizium anisopliae (Metsch.) Sorokin. The most virulent strains of B. bassiana were from Ecuador (code named Bb-4) and two from Mexico (Bb-26 and Bb-17) with CL50's of 5.3x106, 21.9x106 and 293 x106 conidia/ml respectively. Three aggressive strains of M. anisopliae were identified (code named Ma5, Ma23 and Ma4) with CL50 values of 5.4x107, 7.6x107 and 10.6x107 conidia/ml respectively. Lethal time (LT50) tests with B. bassiana showed a range of values between 3.8 and 6.8 days with a mean of 5.3 days. LT50 values in M. anisopliae ranged from 4.4 to 7.2 days with a mean of 5.8 days. The highest incidence of sporulation of B. bassiana on parasitoid cadavers was observed in strains Bb-4 (Ecuador), Bb-17 and Bb26 (Mexico) all with values of 90%. In the case of M. anisopliae, the highest incidence of sporulation on insects was observed in strains Ma5 (84.3%), Ma4 (71.6%) and Ma23 (62.7%).
