MacGregor expects another key factor to lead to a growth in mosquito population as well.
The state saw an increase in Eastern equine encephalitis in mosquitoes last year.
“We’re Iikely to see more EEE this summer,” MacGregor said. “This is just setting the stage for a healthy population in the spring.”
Mosquitoes won’t be the only insect benefitting from this year’s winter.
“Ticks will do pretty well,” said Alan Eaton, an entomologist with the University of New Hampshire Cooperative Extension. “If they have poor snow cover, then they dry out during the winter.”
But Eaton said he doesn’t expect the snow to have translate into any dramatic increase in most insect populations.
“I’m expecting to see normal levels,” he said. “We had relatively good wetness. It won’t be anything dramatic either way.”
