摘要

The Polistes canadensis wasp, present in natural and urban ecosystems, can act as an indicator of environmental quality and/or a biological control of pests. The aim of this study was to investigate the genetic variability of Polistes canadensis in three micro-regions of the state of Bahia, using Inter Simple Sequence Repeat (ISSR) molecular markers for genomic mapping, and also to analyze its venom by high-performance liquid chromatography coupled with UV diode array detector. The results show structured populations, with genetic diversity even in geographically close populations and similar environmental characteristics, and indicated that the four populations are divided into three distinct groups. The chemical study enabled us to analyze the presence of biogenic amine, oligopeptedeo, and enzymes among the venoms and compare them with each other. From this study, one can have the first record of the genetic diversity of Polistes canadensis from the state of Bahia, Brazil, as well as a description of the chemical profile.
