Livestock and Equine IPM Winter Webinar Series

This free online webinar series offered livestock and equine producers, extension educators and agricultural professionals the opportunity to learn directly from researchers advancing practical, science-based solutions to on-farm pest challenges. Each session focused on applying integrated pest management (IPM) principles—combining biological, cultural, mechanical and chemical tactics for effective, environmentally responsible control. Participants learned about tools to identify key pests, understand their life cycles and implement targeted strategies that promote animal health, reduce insecticide use and support beneficial insects.

Recordings of these webinar sessions are available on YouTube at the links below.

January 22–March 5, 2026

Webinar session recordings are available on YouTube.

Pastured Dairy and Beef IPM

Pastured cattle face ongoing challenges from external pests such as horn flies, face flies and ticks. This webinar recording focuses on identifying these pests and using integrated pest management (IPM) strategies to reduce their impact on animal health and performance.

Dairy and Beef Cattle Internal Parasites IPM

Internal parasites such as stomach worms, coccidia and lungworms can affect cattle health and productivity, especially in grazing systems. This webinar recording provides information on tools for monitoring parasite loads, interpreting fecal egg counts and developing strategic deworming plans.

Managing Ticks on Horses

Ticks are a major concern for horse owners and managers due to their role in transmitting diseases and causing irritation and blood loss. This webinar recording presents a discussion of the most common tick species affecting horses, their seasonal activity and habitats.

Tick IPM and New Approaches to Fly Thresholds on Cattle

This webinar recording explores two timely livestock IPM topics—managing ticks on cattle and rethinking traditional fly thresholds.

Ken Wise

Ken Wise is the dairy and livestock IPM Coordinator and associate director of agricultural IPM with  Cornell Integrated Pest Management. He leads statewide efforts to research, develop and evaluate IPM strategies for managing flies, ticks and other livestock pests.

Filth Flies and Biting Insects on Horses, Managing Ticks on Horses

Erika Machtinger, Ph.D.

Erika Machtinger, Ph.D., is an associate professor of entomology at Penn State University, specializing in veterinary entomology and integrated pest management (IPM) for livestock and horses. Her research focuses on developing sustainable, science-based approaches to manage flies, ticks and other pests affecting animal health and welfare. Through her extension and outreach work, Machtinger provides practical guidance to horse owners, veterinarians and agricultural professionals on pest identification, prevention and control strategies that protect both animals and people while reducing reliance on chemical treatments.

Tick IPM and New Approaches to Fly Thresholds on Cattle

Cassandra Olds, Ph.D.

Cassandra Olds, Ph.D., is a veterinary entomologist and assistant professor at Kansas State University, known for her innovative research on livestock pests and her practical, science-based approaches to improving animal health and welfare. She will share her expertise and provide new perspectives on effective integrated pest management for ticks on cattle and how we can rethink fly thresholds.
