Protocol notes

We followed the protocol on the website.

Top gel: arthropod DNA primer

Bottom gel: wolbachia DNA primer

sample in the second lane for both gels

Results
Wolbachia presence Yes
Confidence level Medium
Explanation of confidence level

There was clearly no wolbachia DNA fragments present, but the top half of the gel with the arthropod primer makes us doubt the validity of the entire experiment since it was also unclear if there was arthropod DNA in the sample.
Wolbachia 16S sequence
Arthropod COI sequence
Summary The Lepidoptera was found to be postive for Wolbachia.
