Pesticide deadly to bees now easily detected in honey

Red and yellow wildflowers in a meadow

A common insecticide that is a major hazard for honeybees is now effectively detected in honey, thanks to a simple new method.

Researchers at the University of Waterloo developed an environmentally friendly, fully automated technique that extracts pyrethroids from the honey. Pyrethroids are one of two main groups of pesticides that contribute to colony collapse disorder in bees, a phenomenon where worker honeybees disappear, leaving the queen and other members of the hive to die. Agricultural producers worldwide rely on honeybees to pollinate hundreds of billions of dollars worth of crops.

Q and A with the experts: COVID-19 in our wastewater – What does it tell us?

Mark Servos

Professor Mark Servos and his team have been working since early in the pandemic to develop and validate methods to detect the ruminants of SARS-CoV-2 gene fragments in wastewater. They have been working closely over the summer with other research groups, municipalities and public health agencies to develop and apply the approach and support and inform decision-makers.
