Observations

I caught this hornet in my second floor bathroom. The season was early fall/late summer. The temperature was about 65 degrees F. This is typically a terrestrial organism but was in my home. Color: Black and Yellow,  6 legs, 1 pair of wings,
antennae length of head,  eggshaped abdomen
sharp pinsers.

Putative identification Arthropoda Insecta Hymenoptera

Methods

Extraction kit DNeasy (Qiagen)
DNA extraction location Abdomen
Single or Duplex PCR Single Reaction
Gel electrophoresis system MiniOne
Buffer TBE
DNA stain GelGreen

Protocol notes

PCR

DNA was not properly included during this process. This resulted in a blank gel electrophoresis.

Gel electrophoresis, Arthropod CO1

Lane one contained DNA Ladder, lane two contained A-1 (the hornet), lane 3 contained A-2, these were the only two that did not show up well. I believe the gel electrophoresis reflected an issue regarding the PCR process, the DNA did not show up well due to a lack of DNA in the PCR. Everything else worked well.

Gel electrophoresis, Wolbachia

Lane one contained DNA Ladder, lane two contained A-1 (the hornet), lane 3 contained A-2, lane 3 contained A-3, lane 4 contained A-4, lane 5 contained Wolbachia positive DNA, lane 6 contained Wolbachia negative DNA, lane 7 contained water. Each control worked and outside of A-1 and A-2, no mistakes appeared to have been made.

Results

Wolbachia presence No
Confidence level High
Explanation of confidence level

I a confident that this arthropod is does not have Wolbachia. My thought process being that this PCR along with A-2 were repeated due to a mistake. Since two processes were made to determine they were negative that boosts my confidence further
