Two growth stages, conidia (C) and mycelium (M), and two media, minimal medium (MM) and complete medium (MC), were compared in 10 strains of "M. anisopliae", and two strains of "M. anisopliae" var. "majus" were similar in percentages of total lipids. Tukey test for average of lipid content in conidia (C) and mycelia (M) cultured on minimal (MM) and complete (MC) media showed significant differences between means at the 5(per cent) level of mycelia and conidia, indicating variability in total lipid production and storage during growth. Strains 5 and 7, both variety "majus", did not present sizable differences from variety "anisopliae". For fatty acids, C18:1 and C18:2, oleic and linoleic, respectively, the differences were all highly significant (p=1(per cent)) with highest means being obtained for conidia for fatty acid C18:1 and for mycelia for fatty acid C18:2.
