Fly control strategies topic of upcoming dairy webinar
ORANGE CITY, Iowa — The I-29 Moo University 2021 dairy webinar series continues Friday, Mar. 26 from 12-1 p.m. This month’s topic is strategies for fly control.
Roger Moon, retired veterinary entomology expert from the University of 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,” Fred Hall, dairy specialist with Iowa State University Extension and Outreach said. “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.”
According to Hall, 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. Moon will discuss these issues and provide time for participants to ask questions.
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.
