ABSTRACT
Isolates of entomopathogenic fungus Metarhizium anisopliae var. anisopliae were characterized using internal transcribed spacer-RFLP, ISSR and intron splice site primers. Thirty-seven isolates were studied, most of which were obtained from the sugar cane pest, Mahanarva fimbriolata (Hemiptera: Cercopidae) from Tangará da Serra, Southwest Mato Grosso State, Brazil. Internal transcribed spacer-RFLP did not differentiate the isolates of M. anisopliae var. anisopliae, while ISSR and intron primers identified three distinct groups. Variability among these groups was 96% for (GTG)5 and 100% for the other primers. We found considerable genetic variability, even among isolates from the same geographical origin and host.
Key words: Metarhizium anisopliae, Mahanarva fimbriolata, ITS-RFLP, ISSR, Intron.
