摘要：

Recombination between two strains of Metarhizium anisopliae, subcultured on artificial medium and passed through an insect host was investigated. When grown on agar culture, or passed through a host, strains did not show detectable genetic changes. When passed through an insect in the presence of the other strain, genotypic changes in the isolates, as detected by esterase electrophoresis. restriction digestion of total genomic DNA and RAPD-PCR, were apparent. The instability of molecular markers suggests recombination between strains.
