M.H.P. FUNGARO, M.L.C. VIEIRA, A.A. PIZZIRANI‐KLEINER AND J.L. DE AZEVEDO. 1996. Random amplified polymorphic DNA (RAPD) was used in order to analyse the relationships among 13 isolates of Metarhizium anisopliae var. anisopliae . Six of them were isolated from Deois flavopicta (Stal) (Hemiptera—Homoptera: Cercopidae) in different regions of Brazil. The other seven were isolated from soil in Paraná State in Southern Brazil. The isolates were grouped by cluster analysis using Dice similarity index. The results show that isolates of M. anisopliae var. anisopliae are extremely diverse (47% similarity) but those isolated from D. flavopicta present only a moderate degree of variation (82% similarity) when compared with the wide diversity (31% similarity) found in the group isolated from soil. These results suggest that M. anisopliae var. anisopliae has developed host specificity.
