The temperature needed to kill all stages of any insect is 130 degrees F. for 3 hours. We're not talking about temperature ranges which would affect DNA. Certainly large scale heat treatment of grain silos has not affected the grain's germination rates or its DNA.

(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 [Description: Beskrivning: Beskrivning: Description: Description: Description: Description: nrm_logo] Elin Ohlsson Senior assistant Department of Cryptogamic botany 08-519 541 52 [email protected]<mailto:[email protected]> Swedish Museum of Natural History P.
