Observations

I found the arthropod in a small park under a rock during the fall. it was about 75 degrees outside. The arthropod was in a terrestrial habitat. It is gray, and has many legs.

 
Putative identification Arthropoda Myriapoda Chilopoda Lithobiomorpha Lithobiidae Lithobius Lithobius forficatus

Methods
Extraction kit DNeasy (Qiagen)
DNA extraction location Whole arthropod
Single or Duplex PCR Single Reaction
Gel electrophoresis system MiniOne
Buffer TBE
DNA stain GelGreen
Gel images
Protocol notes

DNA Extraction: I made sure to crush the arthropod really well, the arthropod was small, so no dissection was necessary

Gel Electrophoresis, arthropod CO1:

1 – DNA ladder

2 – A4 DNA

3 – A5 DNA

4- A6 DNA

5 – Arthropod positive control

6 – Arthropod negative control

7 –  water

Analysis: all controls showed expected bands, and the sample showed a arthropod CO1 band.

Gel electrophoresis, Wolbachia:

1 – DNA ladder

2 – A4 DNA

3 – A5 DNA

4- A6 DNA

5 – Wolbachia positive control

6 – wolbachia negative control

7 –  water

Analysis: all controls showed expected bands, and the sample did not show a wolbachia band.

 

Results
Wolbachia presence No
Confidence level High
Explanation of confidence level

All of my controls worked as expected. I did not have any problems
with the protocol, and I was not surprised by any bands on the gel.
Therefore, I am confident my arthropod is not infected with
Wolbachia.

Summary The Lithobius forficatus was found to be negative for Wolbachia.
