Genotypic analysis of Nomuraea rileyi collected from various noctuid hosts.
The genetic diversity of 79 Nomuraea rileyi isolates from various lepidopteran hosts in Asia, North America, and South America was evaluated using amplified fragment length polymorphism (AFLP) analysis. Cluster analysis separated the N. rileyi isolates into two major groups and seven subgroups. The resulting dendrogram generally classified the N. rileyi isolates based on insect host and geographical region. The haplotypic diversity index of N. rileyi subpopulations from each location and host origin was ranging from 0.8788 to 1.000. However, analysis of molecular variance (AMOVA) demonstrated no significant differences (p =0.3421) among N. rileyi isolates from different continents. Whereas the genetic variation among the N. rileyi populations from the different host insects within each continent was significantly different (p <0.0001).
