molecular distinction between populations of gonatocerus morrilli, egg parasitoids of the glassy-winged sharpshooter from texas and california: do cryptic species exist? | two molecular methods were utilized to distinguish geographic populations of gonatocerus morrilli (howard) from texas and california and to test the possibility that this species could exist as a species-complex. inter-simple sequence repeat-polymerase chain reactions (issr-pcr) were performed with a 5'-anchored issr primer. twenty-five markers were generated with four populations (40 individuals) of g. morrilli. twenty-three were polymorphic and the percentage of polymorphic loci was 92%. most ... | 2004 | 15861254 |
