| Abstract Trypoxylon is a genus of solitary crabronid wasps whose population genetics is poorly known. The purpose of the present study was to investigate the genetic variation and differentiation among five populations of Trypoxylon albitarse, a species widely distributed throughout the Neotropics, with records from Panama to northern Argentina. Eight species-specific microsatellite loci were used for genotyping 96 adult wasps (one female per nest) sampled at five sites in Brazil. The analysis of allelic richness and private alleles indicated high genetic diversity in the populations sampled. Pairwise comparisons using the Fst and Dest indices revealed significant differentiation for all, but one pair of populations. Fst, Dest, AMOVA and assignment test... |

| ABSTRACT Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differences on nesting between interior and edge transects. A sum of 1,500 trap nests was made with bamboo cane internodes and two consecutive years were monitored. In the first year 46 nests were occupied by Pachodynerus grandis (19 nests), Pachodynerus guadulpensis (19), Centris analis (two), and Centris tarsata, Megachile fiebrigi, Megachile guaranitica, Megachile susurrans, Trypoxylon sp and Zethus smithii with one nest each. No statistical differences were found between interior and edge transects... |
