The Relationships Between Cuticular Hydrocarbon Composition, Faunal Assemblages, Inter-Island Distance, And Population Genetic Variation In Tuscan Archipelago Wasps, Leonardo Dapporto, Aviva Liebert, Philip Starks, Stefano Turillazzi

Until recently, studies examining the geographical distribution of insects in the Tuscan Archipelago have focused on paleogeography as the primary influence on species distributions. However, for flying insects such as Hymenoptera that may be able to disperse over water, current geographical location is likely to be more important in determining present distributions within the Archipelago. Here we compare mainland and island wasp populations using genetic variation and cuticular hydrocarbon composition of the vespid wasp Polistes dominulus, and species composition of wasps in the family Pompilidae. Both chemical and genetic data result in similar clustering of P. dominulus populations that reflect …

The European paper wasp Polistes dominulus has been expanding its North American range since its introduction in the 1970s. We screened P. dominulus from Italy and the northeastern U.S. for the presence of the intracellular reproductive symbiont Wolbachia. Infection rates among females varied from 16% to 87% among U.S. sites and from 33% to 71% in Italy. We also found infected haploid and diploid males, indicating that this is not a male-killing Wolbachia infection. Our data show that infected individuals from New York, Massachusetts, and Italy carry the same Wolbachia strain, and that some mtDNA haplotypes include both infected and …
