Honey bees
David Tarpy

Researchers at North Carolina State University have come up with a system to evaluate the efficiency and importance of different species of pollinators. 

The study's authors say insects are the primary pollinators of crops.  The researchers developed their system by looking at the behavior of bees in North Carolina blueberry fields. 

Hannah Burrack is an associate professor of entomology at NC State and a co-author of the study.

It’s April, and the scent of flowers is in the air. Unfortunately for allergy sufferers, those flowers also mean that it’s pollen season.  North Carolina pollen counts have been mostly low so far this year, but in the past couple days the count has risen dramatically.
