Abstract

Poor understanding of the population biology of anamorphic Ascomycete entomopathogenic fungi may well be acting as a barrier to the development of new and more effective ways of exploiting them for biological control. It also impacts on bio-prospecting and risk assessment studies for fungal biocontrol agents. We have been investigating the structure of natural Beauveria bassiana populations sampled in England, inspired by the insights of Bidochka and others on the relationship between habitat type and fungal population structure. Isolates of B. bassiana (and other entomopathogenic fungal species) were obtained from c. 4000 soil samples collected from woodlands or grass pastures in a broad transect from southwest to mid-west England. Frequency of occurrence of B. bassiana and other species increased with more northerly latitudes. Multi locus sequence data were obtained for a total of 120 B. bassiana isolates from each sample location. The amount of recombination within clades, evidenced from network analysis, differed markedly depending on the habitat association of the clade. In a second experiment, the same structural pattern was observed for isolates sampled
from a complex of fields and hedgerows on the University farm, with hedgerow acting as a substitute for woodland.
