The process then repeated so, over nine … (Paint fumes apparently were not enough to deter flies, since black-striped cows were bitten just as often as the control group.) “We found that painting zebra-like stripes on cows can decrease the incidence of biting flies landing on individuals by 50 percent,” the study concludes. All it takes to repel pests is a new paint job, researchers say. About half the number of flies landed on the 'zebra cows' - 55 flies, compared with 111 on the black striped cows and 128 on the unpainted cows. Recently, Japanese researchers decided to see if painting stripes on cowswould result in fewer fly and other insect bites. The experiment lasted nine days in total, with each cow once white, once black and once without any stripes. I know I’ve seen horse flies chasing slowly driving cars, for instance. The researchers now say more work is needed, both to confirm the link and to develop less labor-intensive ways of ensuring cows remain patterned and zebra-like.

Number of biting flies on legs and body (a) and the frequency of total fly-repelling behaviors (b) of the experimental cows. The scientists believe the striped pattern confuses the fly’s motion detection and deters the pests. The stripes were drawn freehand, using “commercial waterborne white lacquers” that faded easily. The study, published by Japanese scientists in the journal Plos One, found fly attacks were “significantly reduced” by the disguise. A recent paper describes how a group of scientists painted zebra stripes on cows. Painting cows with zebra-like stripes may be a simple strategy to keep biting flies at bay. A group of agricultural researchers are giving cows zebra-like … This study took these findings in the clever direction of direct application to livestock animals. The laquered bovines were then observed. Study finds painting cows in zebra stripes reduces fly bites By Robert Taylor on 11/10/2019 In an effort to reduce pesticide use, scientists in Japan have found that painting a cow in zebra stripes drastically reduces bites from pesky flies. © 2020 Guardian News & Media Limited or its affiliated companies. The insects interfere with cattle grazing and feeding, increase fly-repelling behaviors like foot stamping and head throwing, and cause cattle to bunch together, which increases heat stress and risk of injury, researchers said. The water-based paint faded within a few days, so while it's a less invasive solution than a pesticide-laced ear tag, it's a short-term one. “Olfaction is also used by the biting flies to find hosts so painting stripes does not completely remove them,” he added. While cows that were either unpainted or painted with black stripes were found to have around 120 bites in a 30 minute period, cows painted with black and white stripes tended to have fewer than 60 in the same period. Meanwhile, the test subjects with the black and white stripes were bitten 60 times in the same time period. Biting flies are serious livestock pests that cause economic losses in animal production. I think it makes sense and could be useful for farmers in the future.”. While unpainted cows and cows with black stripes endured upward of 110 bites in 30 minutes, the black-and-white cows suffered fewer than 60 in the same period, researchers found. They took photos of the cow's painted right side, counting the number of bites as they happened and watching how the cows reacted. The number of biting flies observed on zebra-striped cows was less than half the number seen on unpainted cows and far less than cows painted with black stripes. Only 55 flies were observed on the zebra cows, compared with 111 on the black-painted cows and 128 on the control cows. The research report, “Cows painted with zebra-like striping can avoid biting fly attack,” was carried out by Kojima T., et al and published in PLOS ONE, October 2019. Biting flies cause huge problems for cows, but scientists may have found a very strange way to combat the problem. The scientists that turned a cow into a zebra Scientists discover the real reason for the fashionable selection of zebra stripes. There was over 50% reduction in… It confirmed that the quagga was more closely related to zebras than to horses, with the quagga and mountain zebra (Equus zebra) sharing an ancestor 3–4 million years ago. “They are looking for big, dark, moving shapes. But the results of going zebra were undeniable. If so, it could ease one of the most persistent pest problems that face cattle. Moreover, zebra-striping reduced fly-repelling behaviors by about 20%, indicating that the cows were less bothered by the insects. The quagga was the first extinct animal to have its DNA analysed, and this 1984 study launched the field of ancient DNA analysis. Fly bites are more than an annoyance. A team of researchers painted Japanese black cows with black-and-white stripes as part of the experiment based on the observation that the stripes on zebras seem to … There was over 50% reduction in the number of biting flies seen on … Last modified on Fri 11 Oct 2019 14.30 BST. That method involves painting the cows with zebra-like stripes, which help camouflage the animals from annoying pests. The ersatz zebras were observed to demonstrate only 40 fly-repelling behaviours (such as flicking their tails and shaking their heads) every 30 minutes, compared with 53 and 54 fly-repelling behaviours in the others. Updated 1519 GMT (2319 HKT) October 8, 2019. We found that painting zebra-like stripes on cows can decrease the incidence of biting flies landing on individuals by 50 percent.
