DNA Extraction: Seeing that our controls don’t showcase any signs of DNA, I believe that part of the reason our arthropods don’t have any Wolbachia in them is because we didn’t crush them enough to extract the DNA.

Gel Electrophoresis Lanes for CO1 arthropod PCR: 

  1. DNA Ladder
  2. Arthropod #1
  3. Arthropod #2
  4. Arthropod #3
  5. Arthropod #4
  6. 6th well is the (+) Arthropod Control
  7. 7th well is the (-) Arthropod Control
  8. 8th well is the (+) DNA Control
  9. Finally, the 9th well is the sterile water


Wolbachia presence No
Confidence level Medium
Explanation of confidence level

The bands for my collected sample, Arthropod #2 weren’t visible for Wolbachia which led me to believe that we did a poor job at crushing our arthropods up in the very beginning. This made our results inaccurate.

Summary The Coleoptera was found to be negative for Wolbachia.
