Resumo

Biological control of spittlebugs with Metarhizium (Hypocreales: Clavicipitaceae) in Brazilian sugarcane is an example of effective pest management. However, little is known about the richness, distribution and ecology of Metarhizium species in Brazilian agroecosystems. We investigated Metarhizium diversity within a collection of 96 Brazilian isolates from spittlebugs and other insects, strains used for spittlebug control and soil isolates from sugarcane and other field crops and pristine habitats. A multilocus phylogenetic analysis of 5'-TEF and nuclear intergenic loci MzFG543igs and MzIGS3 yielded robust support for current species limits of the two most abundant taxa, Metarhizium anisopliae and Metarhizium robertsii, and the resolution of two lineages that lie beyond currently recognized species limits in this complex. With a single exception, all isolates from insects belong to a single subclade of M. anisopliae. These data will serve as resources about Metarhizium biodiversity for insect biological control initiatives in South America. (AU)
