It’s been found that a brain chemical, which influences people's moods, can change grasshoppers into frightful swarm of desert locusts, which can cause devastating havoc in the countryside regions. Yes, a study conducted by researchers of the University of Cambridge in England, has revealed that the brain chemical serotonin can turn grasshoppers into horrifying swarms.

Opened on Thursday, the study disclosed that brain chemical serotonin, which is linked with people’s sexual desire, appetite, sleep, memory and learning, can change the usually harmless insects into ganged up bugs that can devastate crops.

Malcolm Burrows, one of the researchers of the University of Cambridge, who worked in the study, said, "Here we have a solitary and lonely creature, the desert locust. But just give them a little serotonin, and they go and join a gang.”

The researchers wrote that the nerve-signaling chemical serotonin appears to be triggering up the behavior changes in grasshoppers. According to the researchers, the results of the study could help to prevent the frightful swarms of desert locusts.

Stephen Rogers, the lead researcher of the study, affiliated both with Cambridge and the University of Oxford in England, said, "Our paper shows how this change in behavior changes what are essentially large grasshoppers living in the desert into swarming, destructive pests.”

In the study published in the journal Science, Rogers and his colleagues concluded that it’s the serotonin that activate the behavior change in the insects that consequently turn them into swarms.

Swidbert Ott of Cambridge, the co-author of the study, "Serotonin profoundly influences how we humans behave and interact, so to find that the same chemical in the brain is what causes a normally shy anti-social insect to gang up in huge groups is amazing."
