Hygienic habit of a swarm - wax moth larvae

[OzBuzz]

I picked up a swarm today! got it home and opened them up - very quickly they started moving rubbish out of the front door and dumping it over the edge. I was inawed when I watched the bees carrying out little larvae - I'm assuming wax moth - when I had a look at the drawn frames I couldn't see ay signs of wax moth. Will they completely remove any larvae? Also, is it difficult for wax moth to get a firm hold in a strong hive?

A strong hive will keep the moths at bay.   They will clean up every frame if they have the bee power.

I've never seen wax moth doing ok in a strong hive. Wax moth will live in your garage in the dirty boxes and the drawn frames you try to keep over winter, atleast up here. I'm going to try melting all the extra drawn frames this winter, they've been such a hassle.

Some people have bred bees specifically for hygienic behavior and it's worked - better resistance to brood diseases for example. They take out a frame of capped brood, kill a certain area of brood without uncapping, then put the frame back in the hive. The bees are graded on how quickly they remove the dead, capped brood.  :)
I wonder if bees could be bred for better grooming behavior for varroa.

In fact, the "SMR" line, standing for 'Suppressed Mite Reproduction' has been re-named "VSH" for 'Varroa Sensitive Hygiene,' research having demonstrated that this line's varroa resistance is a variant of mite-directed hygienic behavior.
