Continued Freezing Could Affect PestsDr. Jim Fredericks

The Northeast, and even the South, has been slammed with snow and
ice over the last month. Although harsh on humans, this
unusually bitter weather could have a beneficial side effect for
regional pest populations.
Many insects have
methods to keep from freezing in the cold such as producing an
antifreeze-type liquid or entering a hibernation period called
diapause. However, the good news is that continued freeze-thaw
cycles increase the likelihood of pests
not surviving. Also, invasive pests who are less well-adapted
to local conditions may have a more difficult time making it to
spring with the current weather trends.
