Protocol notes
  • i had to dissect only the abdomen of the beetle to obtain the reproductive organs due to the hard shell cover of the arthropod
  • PCR and gel electrophoresis was somewhat successful. There are some visible bands, but the information is unclear. We were unable to send our samples in.


Wolbachia presence Unknown
Confidence level Medium
Explanation of confidence level
  • The researched percentage of woodland ground beetles being infected with Wolbachia is very low, so I think that this organism does not have it. Although, it is still unknown.
