Application of Microsatellite Primers Developed for Polistes in the Independent-Founding Wasp Polists satan Bequaert (Hymenoptera: Vespidae)

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.

Isolation and characterisation of microsatellite loci in the wasp Mischocyttarus cassununga

Mischocyttarus cassununga, a primitively eusocial Brazilian wasp, commonly found in urban environments, is an interesting model for studies on the evolution of social behaviour in hymenopteran insects. In this study, we constructed a microsatellite-enriched genomic library and presented primers for 18 microsatellite loci. For the analysis, 20 unrelated females were screened and all loci obtained were polymorphic. PCR amplification revealed from 3 (Mcas5b) to 17 (Mcas53b) alleles per locus (). We detected the levels of observed (H (o)) and expected (H (e)) heterozygosities ranging from 0.150 to 0.950 and 0.261 to 0.920, respectively. The polymorphic information content ranged from 0.238 to 0.915, averaging 0.680. All loci were in Hardy-Weinberg equilibrium and linkage disequilibrium was not detected after sequential Bonferroni correction (P > 0.05). These molecular markers will allow further studies on sociogenetic structure, extensive population genetic analysis and diversity of M. cassununga and other Mischocyttarini species.
