“…The 57 microsatellite locus sequences and priming sites we have published or listed in GenBank will be useful for many studies on wasps from the subfamily Polistinae and may be useful in some members of the Vespinae Choudhary et al, 1993;Strassmann et al, 1996aStrassmann et al, , 1997a.…”

“…We used the methods of Choudhary et al (14) to obtain microsatellite genotypes at all eight loci for a total of 98 early females from 11 1993 colonies (7 single-foundress and 4 multiple-foundress) and 12 1994 colonies (4 single-foundress and 8 multiple-foundress). We used the RELATEDNESS program (version 4.2) of Goodknight and Queller (15), based on the logic of Queller and Goodnight (16), to estimate the mean relatedness among wasps.…”

Dispersal of first “workers” in social wasps: Causes and implications of an alternative reproductive strategy

Many ''workers'' in north temperate colonies of the eusocial paper wasp Polistes fuscatus disappear within a few days of eclosion. We provide evidence that these females are pursuing an alternative reproductive strategy, i.e., dispersing to overwinter and become nest foundresses the following spring, instead of helping to rear brood on their natal nests. A female is most likely to stay and help at the natal nest (i.e., least likely to disperse) when it is among the first workers to emerge and when it emerges on a nest with more pupae (even though worker-brood relatedness tends to be lower in such colonies). The latter cause may result from the fact that pupae-laden nests are especially likely to survive, and thus any direct or indirect reproductive payoffs for staying and working are less likely to be lost. Disappearing females are significantly smaller than predicted if dispersal tendency was independent of body size (emergence order-controlled), suggesting that the females likely to be most effective at challenging for reproductive rights within the natal colony (i.e., the largest females) are also most likely to stay. Thus, early dispersal is conditional on a female's emergence order, the maturity of its natal nest, and its body size. Finally, we present evidence that foundresses may actively limit the sizes of first-emerging females, perhaps to decrease the probability that the latter can effectively challenge foundresses for reproductive rights. The degree to which foundresses limit the size of first-emerging females accords well with the predictions of the theory of staying incentives.

“…In all cases, triploid status was confirmed for each locus upon re-extraction from new tissue. Second, the method used for visualizing alleles differed among studies: the P. fuscatus study used radioactivelylabeled primers and the researchers visualized fragments using autoradiography (as described in Choudhary et al, 1993 andReeve et al, 1998); the P. aurifer study used an automated capillary-method sequencer (CEQ TM 2000 Fragment Analysis system, Beckman Coulter, Inc.; Liebert, 2003); and the P. dominulus study visualized alleles using a LI-COR automated sequencer with Saga™ GT analysis software. Extra alleles due to leakage between adjacent gel lanes could be ruled out by running the samples again after re-extraction in differing order than the original gel loading.…”

Triploid females and diploid males: underreported phenomena in Polistes wasps?

et al. 2004

In hymenopteran species, males are usually haploid and females diploid. However, in species that have complementary sex determination (CSD), diploid males arise when a female produces offspring that are homozygous at the sex-determining locus. Although diploid males are often sterile, in some species they have been shown to produce diploid sperm, thus producing triploid daughters if they mate successfully. Diploid males have been observed in very few species of social wasps, and we know of no published reports of triploid females. In this paper, we review the existing literature on diploid males and triploid females in the Hymenoptera, and report the observation of triploid females in three species of Polistes paper wasps. Although polyploid offspring may be produced parthenogenetically, the more likely scenario is that Polistes wasps have CSD and produce diploid males via homozygosity at the sex-determining locus. Therefore, female triploidy indicates that diploid males do exist in Polistes species where they are presumed to be absent, and are likely to be even more frequent among species that have experienced a genetic bottleneck. We conclude by cautioning against the assumption of a selective advantage to the production of early males, and by discussing the implications of male diploidy and female triploidy for measurement of sex ratio investment and assumptions of reproductive skew theory.
