Even Locusts Hate Plagues of Locusts

Locust swarms have been a persistent problem, affecting crops and food supply globally. These swarms are complex, involving changes in behavior and physiology, and can devastate large areas. Locusts, typically solitary, swarm due to increased population density, leading to cannibalism. Computer models show swarming as a survival mechanism to avoid cannibalism. Recent research suggests a pheromone, PAN, helps locusts avoid being eaten during swarms. Understanding these behaviors could lead to strategies to prevent swarming and reduce agricultural damage.
