Coddling moth, apple maggot, and plum curculios conquered. My first #Rubinette apple has ripened.

Good news/bad news: This cold spell is wreaking havoc on egg masses of the invasive gypsy moth... unless they are insulated under the snow pack. "Cool" new work from our group last week in Journal of Biogeography onlinelibrary.wiley.com/doi/10.1111/jb…

Bring on the #coldsnap! Overwintering #gypsymoth mortality occurs at -27F, and #EAB mortality from -20 to -30F. Remember, actual temps, not windchill.

In the cold winter of 2013-14, #EAB experienced pockets of 60% mortality in the #TwinCities that set populations back nicely. #PolarVortex2019 has been colder, but still won’t eradicate #EAB.

As we emerge from #PolarVortex2019 let us remember the brave insect biological control agents that perished with #EAB. After lessons of cold winter 2013-14, Minnesota efforts funded by MN ENRTF have since focused on a hardier biocontrol species.

One of the finest and most courageous people I know.

Congrats to our PhD student Hailey Shanovich, PhD on recognition as a rising dynamo in applied entomology by Entomological Society of America with the 2020 Larry Larsen award. Nice work Hailey! UMN Entomology Dept CFANS

Lab midterm today in Forest Entomology 4251. Our TA set up a break station at stop #8.

Lab microwave is spotless this morning. Why? I asked person responsible. #stresscleaning post election

Happy Birthday Canada! #Canada150

Surprise guest cicada at kids camp tonight. Impromptu experiment from youth camper concerned about hunger: can it eat goldfish crackers?

I should tweet at least once a century. Happy birthday today to one of our favourite postdocs Kevin Daniel Chase
