Dragon fruit pest bites

Savvas starts with ...
Hello all, I recently bought a pink panther dragon fruit and I'm in the process of getting it acclimatised before repotting it. However some bug has attacked the shoot on top and taken some sizeable chunks out of it. So I'm not sure what to do now with this shoot. Should I leave it alone and will it continue to grow? Also is there any recommendations on what to use to prevent attacks like this? I have a yellow dragon fruit in transit at the moment so would really like to get this under control so we can enjoy both of these magnificent plants.
