Emerald ash borer survives Winnipeg's extreme winter weather
An invasive beetle species is more adaptable to harsh winter weather than previously thought, says a study out of London, Ont.
The emerald ash borer can survive in temperatures that dip as low as –50, and that's not good news for the ash tree population in Winnipeg and throughout Manitoba, Brent Sinclair says.
Sinclair, a biology professor at Western University, and four other researchers published their findings in the Current Research in Insect Science journal on Wednesday.
A previous study said the Asian beetle, which arrived in Winnipeg in 2017, froze to death once the mercury dropped to about –28 C.
