This is the story of two attacks: On July 27, pictures of the ‘attack’ on a pumpkin crop in Las Vegas reached the world.
It caused more trouble than anything and was mainly attracted to the glowing light of this desert city.
At the same time, civil war-torn country Yemen witnessed a pest invasion that is more worrisome and even less mentioned.
It was an invasion of grasshoppers, which has food crops and which can cause serious damage to those crops in more than 60 countries, especially Africa, the Middle East and Central Asia.
The number of such cases will increase, and experts fear that insects may be more destructive and unpredictable due to climate change.
Hunger for a bunch of locusts
There is already evidence that temperature rise will have a direct impact on the digestion of insects.
In 2018, American scientists published a research in the science journal, which shows that warm weather makes insects more active and they breed faster.
This makes them more hungry, and an adult toddler can eat the same amount of food a day.
Researchers estimate that increasing temperature per degree centigrade could increase global damage to wheat, rice and maize crops by 10 to 25 percent due to harvested pests.
This loss can result in moderate climatic areas where most of the grain is grown.
In 2018, the author of the research, Curtus Doshey writes, “In addition to areas near the equator, warmer temperatures will increase the rate of pest production.” You will have more insects and they will eat more food. ‘
Although grasshoppers are not the only species of insects that consume crops, they are the only insects that national and international authorities oversee because of their ability to cause catastrophic effects.
Efforts in the last four decades have made them miserable, but in 2004, an outbreak of the outbreak, similar to the outbreak in Africa, caused an estimated $ 2.5 billion in damage to crops.
Although it is estimated that the global proportion of damage to all insects is relatively low, the researchers estimate it is only 0.2%, the impact of the crowd on a particular place is catastrophic. Can be proven.
Michael Leuk, one of the world’s foremost experts on grasshoppers, told the BBC that “drought in the northern and western range of the desert in the future could create more favorable conditions for the breeding of locusts and its Negative effects can also occur. ‘
“This can have enormous consequences for many poor people in developing countries, including crops, pastures and ultimately food and social security,” Liuk warned.
According to the UN World Food Program, the most destructive plague species are desert locusts, which have a potential to harm livelihoods by 10% of the world’s population.
A small swarm of these locusts eats up to 35,000 people a day.
His favorite foods include cereal plants such as wheat, rice and corn.
As mentioned in the Qur’an and the Bible, this creature is the oldest enemy of humanity.
Ancient Greek historian Pliny the Elder said that the plague of locusts killed 800,000 people in the famine. These areas are now Libya, Algeria and Tunisia.
In 1958, a group of locusts in Ethiopia destroyed 167,000 tonnes of grain over an area of more than 1,000 square kilometers, enough to feed one million people a year.
The milder areas will be more affected by these hungry pests because if these areas get too hot, digestion of these pests will slow down as this problem is already facing the equatorial regions.
Experts suspect that global warming has played a major role in 2016, when Argentina faced the largest locust attack in the past 60 years.
Hot and humid winters are blamed for this trend.
Warmer temperatures can help insects fly higher and cross natural barriers such as mountains and open up new routes for them to move, especially if the direction of the flight is in their direction. If so, she can take them farther.
“Climate change in general is more likely to cause attacks and increase in locusts,” says Arianez, director of the Global Locust Initiative at Arizona State University.
Food cultivators are most at risk of injury by locusts.
But not only food crops are at risk, but in Pakistan, authorities are working to counter an attack that threatens the cotton crop, which accounts for half of the country’s exports.
