The migratory locust is the most widely distributed locust species on the planet. Like all locust species, these insects can follow one of two paths as they mature: some become solitary creatures, while others gather together in a cohesive mass.

Vosshall added that pesticides "are the only effective weapon for fighting such locust plagues," but the size and unpredictability of the swarms force governments and farmersto spray it unnecessarily far and wide. These chemicals can harm other animals, plants, and possibly people. But the discovery of 4VA could facilitate a more surgical approach ...
In her article, Vosshall described how heavy rains has helped birth a growing population of swarming desert locusts in Africa and Asia. "This year is a plague year," she wrote. Although the desert locust is not the species she studied, Vosshall said that it nonetheless "seems very likely that what was learned from the migratory locust can be applie...
