| Abstract: | Ten lipase-negative mutants from a lipase-positive virulent strain of Beauveria brongniartii were found to be avirulent, similar to lipase-negative strains isolated from nature. Two morphological mutants and four auxotrophic mutants which were lipase positive were also avirulent. Hypotheses to explain these results are presented. |
