Microsatellite primers developed for a given species are sometimes useful for another in the same genus and in other genera within the same family, making possible to search for pre-existing suitable primers in the databanks such as GenBank. We examined whether existing primers developed for Polistes could be used for Polistes satan Bequaert. We tested 50 microsatellite primers from three Polistes species and found that six microsatellite loci show polymorphism in size in P. satan. These six loci were highly polymorphic, having four to 15 alleles in P. satan with an expected heterozygosity of 0.525-0.832. These loci can be used to study parameters concerning genetic relatedness such as social interactions in colonies and genetic conflicts of interest among nestmate individuals.

Abstract Background Swarm-founding epiponine wasps are an intriguing group of social insects in which colonies are polygynic (several queens share reproduction) and differentiation between castes is often not obvious. However, caste differences in some may be more pronounced in later phases of the colony cycle. Results Using morphometric analyses and multivariate statistics, it was found that caste differences in Metapolybia docilis are slight but more distinct in latter stages of the colony cycle. Conclusions Because differences in body parts are so slight, it is proposed that such variation may be due to differential growth rates of body parts rather than to queens being larger in size, similar to other previously observed epiponines.
