Pd. Bridge et al., MOLECULAR CHARACTERIZATION OF ISOLATES OF METARHIZIUM FROM LOCUSTS AND GRASSHOPPERS, Biodiversity and conservation, 6(2), 1997, pp. 177-189
The relationships between 30 strains of Metarhizium were investigated
by isoenzyme analysis, PCR-RAPDs, and protease production. The strains
included representatives of M. anisopliae, M. flavoviride var. flavov
iride and M. flavoviride var. minus. Thirteen isolates conforming to M
. flavoviride from acridoid hosts and pathogenic to locusts and grassh
oppers were shown to be a single, distinctive genotype with a pan-trop
ical distribution. In addition, the separation of M. flavoviride ide v
ar. minus as a host specific taxon distinct from European isolates of
M. flavoviride was also supported. The possibility of coevolution with
in some insect pathogenic populations is discussed.
