Observations

We caught this Scolopocryptops sexspinosus covered in leaves about 2 inches underground. This centipede was orange in color and approximately an inch in length. Scolopocryptops sexspinosus, or the Eastern Red Centipede, is native to North America and is often found hiding under rotting wood or leaf litter.

Methods
Extraction kit DNeasy (Qiagen)
DNA extraction location Whole arthropod
Single or Duplex PCR Single Reaction
Gel electrophoresis system Standard electrophoresis system
Buffer TAE
DNA stain SYBR Safe
Gel images
Protocol notes

The centipede was identified using the SEEK app. After identification, the centipede’s DNA was extracted, and we performed PCR for Wolbachia 16s ribosome and Arthropod COI gene. After amplifying the DNA, we then ran the DNA through a gel electrophoresis system, and scanned the gel to confirm or deny the existence of Wolbachia DNA and Arthopod DNA in our sample. The gel results don’t have a band at 708bp for the Arthopod COI gene, but the identity of the bug is confirmed from the sequencing results.

Results
Wolbachia presence No
Confidence level High
Explanation of confidence level

There are no bands on the gel at 438bp, which is the expected band size for the Wolbachia 16S rRNA gene. Additionally, there is no sequencing product that confirms the presence of Wolbachia DNA in the sample.
