PCR 2- Date : 4/3/2025.                                                                      Primers – Wolbachia.                                                             Annealing Temperature: 55C

 

Results
Wolbachia presence No
Confidence level Medium
Explanation of confidence level

Wolbachia is pretty common in arthropods and lady beetles.

The controls did work because the controls that needed a band had bands. The confidence level is medium because the           (+) Arthropod was faint, so when doing the first PCR the bands were clearly displayed and when did the second PCR the bands appeared faintly.
Wolbachia 16S sequence
Arthropod COI sequence
Summary The Arthropoda was found to be negative for Wolbachia.
