[Nhcoll-l] freezing blown eggs

[Rogers, Steve]

Greetings Tonya,

The entire inside lining of the egg is certainly susceptible to being eaten. I blew a series of eggs once and did not put them in my screened in drying cabinet. I ended up getting a few phorid flies find their way through the holes, breeding and multiplying. I have also seen various small beetles inside older eggs in the collection within the genus Anthrenus. The cotton surrounding the egg set showing past infestations.

I would recommend freezing them like you would other dry specimens, inside plastic so no condensation on the specimens happens after bringing them up to room temperature.

Subject: [Nhcoll-l] freezing blown eggs


Hello all,



I am wondering if any of you have thoughts on freezing egg collections for pest control? I imagine that it is probably ok, but then I wonder if there could be problems to the shell structure. Note I realise that there is not much for museum pests to eat in a blown egg, but there are lots of places for them to hide in and around the their housing. As usual, any thoughts or feedback would be very appreciated!



Cheers,



Tonya
