EXTENSIVE SEQUENCE DIVERGENCE IN THE ITS2 RDNA FRAGMENT IN A POPULATION OF GONATOCERUS ASHMEADI FROM FLORIDA: PHYLOGENETIC RELATIONSHIPS OF GONATOCERUS SPECIES

  • Author(s): de Le?n, Jesse; III, Russell; Jones, Walker; Morgan, David;
  • Abstract: The aim of the present study was to resolve the genetic relationships of geographic populations of Gonatocerus ashmeadi, a primary egg parasitoid of the glassy-winged sharpshooter. A phylogenetic approach was implemented by sequencing the Internal Transcribed Spacer-2 (ITS2) region of several individuals per population. In addition, the phylogenetic relationships of several Gonatocerus species were also determined. Six geographic populations of G. ashmeadi were analyszed: Quincy
