The pine beetles are still causing issues up here. I read an article a couple years back and if I recall correctly for them to die off completely the temp needs to stay below -15 for 3 weeks or something along those lines.
We do get temps that cold, but they usually don't last for 3 weeks straight.
At least the little fleas/flies that were causing EHD (Blue Tongue) in the Deer, Elk and Antelope were killed off last year or at least reduced significantly as I did not see or hear about mass die off's of the animals this year.
Quoting: Sol Neman -15 for 3 weeks! Nope, those temps are not seen. Can't imagine that going to happen soon, unless all the volcanic activity we have been having, accompanied by less solar activity (that isn't happening) might cool things off. I was a little off. 'Extreme cold temperatures also can reduce MPB populations. For winter mortality to be a significant factor, a severe freeze is necessary while the insect is in its most vulnerable stage; i.e., in the fall before the larvae have metabolized glycerols, or in late spring when the insect is molting into the pupal stage. For freezing temperatures to affect a large number of larvae during the middle of winter, temperatures of at least 30 degrees below zero (Fahrenheit) must be sustained for at least five days. [ link to www.ext.colostate.edu] It would be very unusual to get those kind of temps for the length of time needed. We might get to -30 overnight, but to have it stay that cold or colder for 5 days straight would require some drastic changes in weather. If the volcanoes continue to saturate the atmosphere with ash and the Sun becomes less active it may happen, but I think we would have bigger issues to worry about besides the pine beetle if that were to occur... No kidding. We would be busy cutting those trees down for warmth!!! On the positive side, beetle killed trees burn extremely easy and very hot. So we should be able to stay warm...at least until there's 30+ feet of snow on the ground covering all the trees and collapsing most structures.
