Single Arthropod PCR set up on March 6th, 2025 to amplify fragment of the CO1 cytochrome oxidase gene using Arthropod_F (LCO1490) and Arthropod_R (HCO2198) Primers with an annealing temperature of 49°C.

Separate Single Wolbachia PCR set up on March 27th, 2025 to amplify fragment of the 16S ribosomal RNA gene using Wolbachia_F (16S_WspecF) and Wolbachia_R (16S_WspecR) Primers with an annealing temperature of 55°C.

Results
Wolbachia presence No
Confidence level Medium
Explanation of confidence level
Wolbachia 16S sequence
Arthropod COI sequence
Summary The Decapoda was found to be negative for Wolbachia.
