Webinar On Fly Control Set For March 26

The I-29 Moo University 2021 Dairy Webinar Series continues Friday, March 26 from 12 noon to 1 pm. This month’s topic is fly control strategies. Dr. Roger Moon from Minnesota will identify common pest flies and how to manage them on confinement dairies.

Different kinds of flies can bother your cows, workers and neighbors. Stable flies bite, cause cows to bunch, reduce milk production, breed mainly in soiled cow and calf bedding, and pretty much stay on the premise. House flies breed in wetter manure, annoy people, and spread off premise to bother neighbors. Routine premise sprays and fogs can keep numbers of both kinds low in confined spaces, but targeted source reduction through debris management outdoors is a more sustainable approach. Listen to Dr. Moon discuss these issues and ask him questions.

Dr. Roger Moon retired from University of Minnesota’s Entomology department in 2016 after 36 years of service in research, teaching and outreach in Veterinary Entomology. He continues to study and publish on the biology, ecology and management of filth flies and other arthropods that occur around livestock, wildlife and people.
