Do they look like Fig 13?

I doubt if they are dust mites, because I have not seen mites anywhere else, but  I must admit to not looking at a dust mite for comparison.

I shall take you up on your offer, if I can find some more – as I said in an earlier email, they seem to be less obvious at present. Where shall I post them?

 

Cheers

Don

 

 

 

If they are eating the gum on the cards, they could be one of several species of astigmatid mites that are associated with starch products. If you send me a (largish) sample, Don, I'll put a name on them.

Hi are these just dust mites? They feed on minute particles of organic matter and especially that digested from fungi hence liking the damper environment. Booklice feed on microscopic fungi so they too would be found in regions of higher RH.

Are they book lice (psocids) – they love damp and eating glue and starches

 

Wrap your collection in polythene, taped up properly and freeze it for 14 days in you domestic freezer (these run at -18 normally)

Recently I have had problems with an infestation of mites in part of an entomology collection - not the one here I hasten to add!  The mites are very small and completely white, and probably became established when the collection was in a dampish room (and helped to inform my decision to move house) and remained unnoticed. I don’t know what species they are, but I think they were eating the gum attaching beetles etc to cards, and left lots of tiny frass, and cast skins. I haven’t seen any recently, possibly because the collection is now in a drier atmosphere. However, I would like to treat the whole collection with a generic insecticide or possibly an acaricide.

Has anyone got any ideas as to what I should use?

I don’t recollect seeing anything about mites in insect collections and can’t find anything to indicate what species they may be.
