Abstract

Three different extraction methods for preparing DNA from single grape phylloxera (Daktulosphaira vitifoliae) eggs for use in PCR-RAPD assay were compared. Pulverization in a glass micro-grinder produced much more clear and consistent RAPD results than when the egg DNA was extracted with a Chelex lysis or a proteinase-K+ lysis. Multiple single egg extractions from the same parthenogenetic colony were done with all three methods; no RAPD assay differences were detected. This technique will allow evaluation of the roles population diversity, mutation rates, and reproductive mechanisms play in the Vitis/phylloxera interaction.
