Invasive species cause extensive damage to their introduced ranges. Ocean archipelagos are particularly vulnerable to invasive taxa. In this study, we used polymorphic microsatellite markers to investigate the genetic structure of the social wasp Vespula pensylvanica in its native range of North America and its introduced range in the archipelago of Hawaii. Our goal was to gain a better understanding of the invasion dynamics of social species and the processes affecting biological invasions. We found that V. pensylvanica showed no significant genetic isolation by distance and little genetic structure over a span of 2000 km in its native range. This result suggests that V. pensylvanica can successfully disperse across large distances either through natural‐ or human‐mediated mechanisms. In contrast to the genetic patterns observed in the native range, we found substantial genetic structure in the invasive V. pensylvanica range in Hawaii. The strong patterns of genetic differentiation within and between the Hawaiian Islands may reflect the effects of geographic barriers and invasion history on gene flow. We also found some evidence for gene flow between the different islands of Hawaii which was likely mediated through human activity. Overall, this study provides insight on how geographic barriers, invasion history, and human activity can shape population genetic structure of invasive species.

Irregular brood patterns and worker reproduction in social wasps

The potential for reproductive conflict among colony members exists in all social insect societies. For example, queens and workers may be in conflict over the production of males within colonies. Kin selection theory predicts that in a colony headed by a multiply-mated queen, worker reproduction is prevented by worker policing in the form of differential oophagy. However, few studies have demonstrated that workers actually lay eggs within queenright colonies. The purpose of this study was to determine if workers laid male eggs within unmanipulated queen-right colonies of the polyandrous social wasps Vespula maculifrons and V. squamosa. We focused our analysis on an unusual brood pattern within colonies, multiple egg cells. We were primarily interested in determining if individuals reared in these irregular circumstances were queen or worker offspring. To address this question, we genotyped 318 eggs from eight V. maculifrons and two V. squamosa colonies. No worker reproduction was detected in any of the queenright colonies; all of the eggs found in multiple egg cells were consistent with being queen-produced. However, the frequency of multiple egg cells differed among colonies, suggesting that queens vary in the frequency of errors they make when laying eggs within cells. Finally, we suggest that workers may not be laying eggs within queenright colonies and that worker reproduction may be controlled through mechanisms other than differential oophagy in polyandrous Vespula wasps.

“…Consequently, this effect could influence the genetic components within populations. In annual eusocial wasps, apparent IBD and/or population structuring have rarely been observed (Queller et al 1992;Strassmann et al 1995;Hoffman et al 2008), with a few exceptions (Davis et al 1990;Goodisman et al 2001). Together, these studies suggest that eusocial wasps could be strong fliers; this trait together with an annual life history could impede population structuring and/or mask patterns of IBD within populations.…”

Dispersal triggers gene flow, which in turn strongly affects the ensuing genetic population structure of a species. Using nuclear microsatellite loci and mitochondrial DNA (mtDNA), we estimated the genetic population structure of the wasp Polistes olivaceus throughout Bangladesh. The level of population differentiation using nuclear markers (F ST ) appeared to be much lower than that estimated using mtDNA haplotype sequences (A ST ), even after correcting for effective population size differences between the two markers. These results suggest a philopatric tendency, in which gynes disperse less than males. We observed no isolation by distance among the study populations at either the nuclear or mtDNA level, suggesting nonequilibrium between gene flow and drift as a result of very frequent interpopulation movement. For the nuclear markers, an individual assignment test showed no genetically and geographically distinct groups. Instead, phylogenetic analyses as well as a minimum spanning network using mtDNA haplotypes consistently revealed two distinct lineages. The distribution of haplotypes indicated western populations with a single lineage and offered clear evidence for restricted gene flow across the JamunaPadma-Upper Meghna river system. Mismatch distributions exhibited a unimodal distribution, which along with a starlike haplotype network, suggested a population expansion in lineage I but not in lineage II. Overall, these results suggest that gene flow among populations of P. olivaceus was affected by both female philopatry and a major river system across Bangladesh.
