Colorado Potato Beetles require a certain amount of heat to break their winter dormancy. University of Minnesota Extension entomologist Ian MacRae saw the pest show up later than usual this season. “We had that early season heat before it got cold again, so I think that reset their starting clock.” Late season PVY or Potato Virus Y is the biggest concern right now. “It certainly took a leap this last week when we saw a lot more of the aphid species that transmit Potato Virus Y.”
