[Nhcoll-l] heat treatment

[Anderson, Gretchen]

Hi Ellen - I suggest that you look at the Museum Pest Network.  http://www.museumpests.net  I believe that there is white paper on heat treatment.  If that is not up yet, post your question on the pest list. - that is where you will find the most people who have worked with heat.  Tom Strang at CCI has run experiments with it - and advocates heat as a method his research is published on the CCI web site http://www.cci-icc.gc.ca/caringfor-prendresoindes/articles/10agents/chap06-eng.aspx#pest-parasites10c .

As for DNA - you will have to look at the specific temperatures critical for your specific pest to see if that temperature will affect the DNA.  Again - see Tom's research at the above link.

Good luck.

Subject: [Nhcoll-l] heat treatment

Hi all,

We are having trouble with pest infestation in our herbarium and are considering heat treating a whole room instead of fumigation with toxic gases. (We are already working with cleaning the rooms, freezing and bagging of specimens but it is not enough). Is there anyone with experience of heat treatment in large areas or maybe has any documentation? We are mostly concerned about the effect on DNA.

Thanks for any information

Best regards,

Elin
