Guest guest Posted November 30, 2008 Report Share Posted November 30, 2008 I found a study of a comprehensive study of D. Gallinae living, reproducing, and dying behaviors in relation to temperature and humidity. It's similar to those files Jeff found (links to those studies are in msg " A theory: please don't water the mites " # 4540). If it's been posted before sorry... I read this w/ great interest: http://www.nhm.ac.uk/hosted_sites/acarology/saas/e- library/pdf000200/a000115.pdf Among what's written, the study indicates that D. Gallinae subjected to -20C all died within 20 min. I can set my fridge temp to a low of -7F, which is -21C and I actually do have it packed with quite a few items inside (clothing, books, etc) and maybe one box of frozen pizza... ahhh, I miss eating ice cream at home. This is also a powerful finding (in line w/ the study Jeff found that said 9 months): " However, mites could survive for a long time (8 mo) in an empty chicken hut during natural conditions, with temperatures ranging from -10 to +27C (Kirkwood 1963). However, it remains to be investigated how temperatures below zero are tolerated by D. gallinae, especially when mites are gradually adapted. " It also says: " The same has also been suggested for controlling O. sylviarum (Northern Fowl Mite), which can withstand temperatures of -20Cfor 5 d but temperatures.498Cfor only 2 h, off the host (DeVaney 1986).
