Cows painted with zebra-like striping can avoid biting fly attack

Area of Science:

• Zoology
• Animal Science
• Applied Entomology

Background:

• Biting flies pose significant threats to livestock, causing economic losses in animal agriculture.
• Zebras' striped coats are known to deter biting fly attacks, suggesting a potential application for livestock.
• Pesticide resistance in insects necessitates alternative pest control strategies for animal production.

Purpose of the Study:

• To investigate if painting black and white stripes on cattle can reduce biting fly attacks and associated behaviors.
• To evaluate the efficacy of striped patterns as a non-pesticidal method for livestock protection.
• To explore a novel approach for managing biting flies in animal production systems.

Main Methods:

• A 3x3 Latin-square design was employed with six Japanese Black cows.
• Cows were subjected to three treatments: black-and-white stripes, black stripes only, and no stripes (control).
• Fly-repelling behaviors and counts of biting flies on cows were recorded and analyzed from photographic images.

Main Results:

• Cows painted with black-and-white stripes exhibited significantly fewer biting flies compared to control and black-striped cows.
• The frequency of fly-repelling behaviors (head throw, ear beat, etc.) was lower in the black-and-white striped group.
• Striped patterns effectively deterred biting flies, reducing both direct attacks and behavioral responses.

Conclusions:

• Black-and-white striped patterns on cattle can effectively prevent biting fly attacks.
• This method offers a viable, pesticide-free alternative for protecting livestock against biting flies.
• Implementing striped patterns can contribute to sustainable animal production by mitigating pesticide resistance issues.
