Abstract


Entomopathogenic fungi  such as Beauveria bassiana are important natural control agents of many insects and can be potentially used as a bioinsecticide against several pests. Other potential source of bioinsecticide is certain plants such as fragrant lemongrass oil.  The in vitro compatibility of the entomopathogenic fungus B. bassiana  and  fragrant lemongrass oil was evaluated.  Fragrant lemongrass oil was tested in three different concentrations (0.1, 0.3 and 0.5%). Fragrant lemongrass  oil  was diluted in the steril SDAY medium at the different concentrations. Effects of these concentrations on conidia germination, colony growth and sporulation were compared.  Fragrant lemongrass  oil  affected conidial germination, colony growth and sporulation of B. bassiana. Fragrant lemongrass  oil  was not compatible with the entomopathogenic fungus B.  bassiana.
