| allozyme differentiation among nine populations of the corn borer (ostrinia) in china. | to test the hypothesis of the migration of the corn borer, the allozymes of nine populations of the corn borer (ostrinia) in china were checked using vertical-slab polyacrylamide gel electrophoresis. eight loci of six allozymes were analyzed. the mean of the genetic identities among the nine populations calculated from the allele frequencies was 0.99068, much closer than that of other species and geographical populations. the mean (0.97955) of the genetic identities between the xjyn population ( ... | 1995 | 8825941 |
