What if cows might keep away from flies from biting them simply by sporting stripes?
In response to a brand new examine revealed in PLOS ONE, when Japanese researchers painted zebra-style stripes on cows, biting flies bothered them half as a lot than cows with out stripes.
The thought is that stripes might certainly confuse insect movement detection techniques that management whether or not flies strategy or land on the striped animal.
For the examine, researchers painted six Japanese Black cows with black-and-white stripes, then noticed cows with and with out painted stripes for 3 days.
Researchers snapped high-resolution pictures of the cattle at numerous occasions to depend the variety of bugs pestering the cows. In addition they noticed the cows to see in the event that they stamped their legs, moved their tails and and different traditional bodily behaviors to repel the flies.

Researchers continued to look at the striped cows to see if the paint chemical compounds truly repelled the flies. In response to the outcomes from examine, the variety of biting flies seen on the striped cows was lower than half the quantity seen on unpainted cows.
“We discovered that portray zebra-like stripes on cows can lower the incidence of biting flies touchdown on people by 50%,” in line with the examine’s findings. “We additionally discovered that the decreased landings of biting flies coincide with a discount in defensive behaviors in cows.”
At present, the livestock business makes use of pesticides on cattle to combat off biting flies, however this analysis might show there’s a much less poisonous, and probably cheaper, various to utilizing chemical compounds.
“This work supplies a substitute for the usage of typical pesticides for mitigating biting fly assaults on livestock that improves animal welfare and human well being, along with serving to resolve the issue of pesticide resistance within the surroundings,” the examine said.
