The mating behavior of individuals ofDrosophila pseudoobscura from New Zealand

Summary Recently discovered individuals in New Zealand of the North American speciesDrosophila pseudoobscura were analyzed for any divergence in mating behavior. Cultures collected from five localities in North American were mated with a stock from Rotorua, New Zealand. No significant divergence was obtained in any of the within North Americ, and more importantly, between North American and New Zealand mating experiments. Further analyses also showed no development of sterility between recently caught New Zealand and North American flies. We discuss our results in relation to others of this type.Publication No. 5 from the Evolutionary Genetics Laboratory, University of Auckland.Acknowledgements.
