Following a practice in China and other Asian countries, researchers at the Chelyabinsk State Agriculture Engineering Academy have invented mobile machines capable of collecting locusts and grinding them into nutritious fodder for livestock. The scientists claim other solutions already present on the market are not as efficient since they involve collecting adult insects which have already sprouted wings, as they lose most of their nutritional value by then. The inventors believe that locusts should be processed into fodder while still wingless. The tests of the new technology, conducted in Southern Russia, have shown some very positive results.
Locusts attack crops in swarms 1.5 to 2 kilometers wide, the “carpet” of insects covering the ground being 20 to 25 centimeters thick. Locust invasions occur yearly in all the regions of Southern Russia and Kazakhstan. According to the scientists at Chelyabinsk Academy, locusts caused billions of dollars worth of damage to the farmers of Bashkiria and the Southern Urals in 2014.
With about 75 percent of their dry weight composed of protein, locusts are much more nutritious than meat or fish (the percentage of protein is 17 for pork and lamb, and 21 for fish). The Russian developers affirm that while similar solutions for transforming locusts into fodder are already implemented in some countries, including China, they rely exclusively on catching winged adult insects, and at this point of their life-cycle they lose most of their nutritional value.
“Winged locusts contain less nutrients, so when they are processed, the results are underwhelming. We catch them as they are moving through the fields, at the stage when they quickly consume vegetation and grow. The machine we invented collects about 70 percent of a swarm, crushing the rest. After a single pass, no insects are left,” says provost of Chelyabinsk Academy Peter Svechnikov.
The technology was born in the Southern Urals about 10 years ago, after one of the inventors stumbled on an article lamenting the great damage caused by the insects and the enormous expenses of containing the threat.
“Our partners in Tajikistan, Uzbekistan, Kalmykia and Saratov have been requesting us to develop a solution to process locusts for a long time,” Svechnikov says. “We tackled the issue, making several trips to the south of the country to test some solutions. The technology has already become popular, with orders pouring in ever since, some of them from abroad.”
The developers estimate the implementation of the new technology to cost a $30,000 to $40,000. The buyer would be able to recover the costs in a week. The cost of their equipment is put at $10,000. According to the scientists, the production cost of a kilogram of locust meal will be about 10 rubles (20 cents), the market price of the fodder being five times higher, to the tune of a dollar.
The admittedly unusual idea of processing locusts into animal feed left most Russian agriculture experts somewhat confused. None of the officials at the Russian Animal Farmers Union, Ministry of Agriculture or the Union of Agricultural Cooperatives could comment on the prospects of the new technology.
Chairman of the Urals Livestock Breeders' Union Ilya Bondarev believes there are not enough locusts in Russia for the technology to be financially feasible. “Think of how high the consumption of animal feed is, and compare that to the number of locusts that is needed,” Bondarev told RIR. “Besides, locusts are sprayed with pesticides. How exactly are we supposed to use contaminated insects in fodder.”
Nevertheless, the inventors are convinced there will be enough insects to go by as the mass of an average locust swarm can touch 35,000 tons, and invasions occur each year. Georgy Gaidadin, CEO of the Russian fodder production company Bioenergiya believes the technology holds great promise. “At the moment, fishmeal is considered to be the most nutritious fodder supplement. But the world is running out of fish, so locust meal may well become a excellent alternative source of easily digestible protein for different species of domestic animals and birds,” says Gaidadin.
