How Far Do Fly Pests Fly?

This February 2014 article, "Use of a Highly Sensitive Immunomarking System to Characterize Face Fly (Diptera: Muscidae) Dispersal from Cow Pats," describes work conducted on fly dispersal using a protein-based marker to track dispersal of 663 flies. The implications for rotational grazing and other IPM strategies are discussed.

Results of Ear Tag Trials on Horn and Face Flies

Horn flies and face flies are the two main fly pests of pastured cow‐calf herds in Washington State. To test the field effectiveness of commercially available insecticide ear tags against these two pests, trials were conducted in Benton County during the summer of 2011. Dr. Holly Ferguson's article, Ear Tags Effectively Reduced Horn Flies on Pastured Beef Cattle, on page vi of the Spring 2012 Washington Animal Agriculture Roundup newsletter summarizes the results.

WSU's Animal Ag Team's fact sheet Do You Have Lousy Animals? is a brief overview of species-specific lice and how to diagnose and treat your livestock. The 3-page overview includes louse life cycle, signs of infestation, and effective treatment recommendations.
2014 Beef Management Calendar
WSU Extension's 2014 Beef Management Calendar is a customizable, month-at-a-glance calendar that includes instructions on how to set up a useful reference for your cattle production operation, including economic, feeding, breeding, calving, herd health, and other management concerns.

Summer 2010 Animal Ag Newsletter Animal Ag Team Newsletter Features Horn Fly Article
The Summer 2010 WSU Animal Agriculture Extension Newsletter features an article by Dr. Holly Ferguson entitled A New Way of Looking at Horn Fly Control, in which she discusses horn flies and face flies, utilization of digital photography in assessing fly counts, and methods of fly control.
WSU/USDA Risk Management Agency Cattle Partnership Concludes
A four-year partnership between WSU researchers and the Federal Crop Insurance Corporation's Risk Management Agency has concluded. The project laid the fuondation for a science-based IPM program for Pacific Northwest rangeland cattle, including research into beef measles, rotational grazing, pesticide impacts on beneficial fauna, a novel fly control system involving pesticide-impregnated netting, and two entirely new research methods for tracking flies. The project is summarized in this May 2010 report.

Techno-Cow: More than One Way to Count Flies!
Dr. Holly Ferguson discusses the importance of fly counts in determining thresholds for IPM in livestock and introduces a more accurate, labor-saving counting technique under development. This technique uses digital photography and a grid pattern. The seminar, A Thousand Points of Flies, was presented December 2008.
Rotational Grazing -- Effective or No?
Mark/Recapture Studies of Dung Fauna from Cow Pats, presented by Dr. George Peck in November 2008, shows deployment of our immunomarking technique to track movement of horn and face flies toward an understanding of the impacts of rotational grazing on pest management.

Spring Edition of WSU Livestock Round-Up
The Washington Animal Agriculture Team and Washington State University Extension have released their May 2007 Newsletter. Articles include discussion of horn fly and face fly on cattle, recognizing and treating colic in horses, identifying and eradicating scrapie in sheep and goats, and three pasture management articles (controlled grazing, grazing for weed control, and the merits of grazing stock on forage kochia).

New Extension Bulletin Surveys Pest Management Practices
Our research team conducted a survey of Washington State beef cattle producers in the fall and winter of 2005/2006 to assess cattle pest prevalence and pest control product use and effectiveness. The resulting data were analyzed and are presented in Washington State University Extension Bulletin EB2017E, Survey to Assess Parasite and Fly Control Methods Utilized by Washington Beef Cattle Producers. The document is available free of charge as a PDF download. It includes a brief overview of the state’s beef cattle industry. describes the major internal and external parasites/pests, and summarizes the results of our survey. The data will serve as a foundation toward addressing increasing concerns among cattle producers about inefficient and unsustainable pest management practices.

Survey Poster Presented at Livestock Insect Workers Conference
In June 2006, our team presented preliminary results of our cattle producer survey at the national Livestock Insect Workers' Conference in Amarillo, Texas. View a miniature version of this poster by clicking here or on the poster image at right. These survey results are summarized in the 16-page Extension Bulletin publication above.

  A 3-Year Research Project
began in 2006 to reduce risk in rangeland beef cattle production. This poster explains the basic parameters of the research and outlines the deliverables from the IPM Livestock Team in charge of the project. Directed by Dr. Doug Walsh, the research addressed internal and external pests identified as most economically important by Washington State rangeland beef producers. This project was funded by and conducted in partnership with the USDA Federal Crop Insurance Corporation's Risk Management Agency.
