Population structure of Aedes albopictus (Skuse): the mosquito which is colonizing Mediterranean countries.

@article{Urbanelli2000_aedes, abstract = {Multilocus electrophoresis analysis has been used to study the genetic structure of 18 populations of Aedes albopictus newly introduced to Italy, in comparison with two populations in the United States, four in Japan, and four in Indonesia. Allozyme analysis revealed that 15 out of the 18 studied loci were polymorphic among the 28 populations. No significant deviations from Hardy-Weinberg equilibrium were found at polymorphic loci. High genetic affinity was observed between the Italian populations and those from the United States and Japan. The analysis of variance in allele frequencies showed that variance among subpopulations accounted for most of the total variance, suggesting that isolation of the Italian populations is not related to distance.
