As my lab is virtual, here, and not in the sahel migratory path, I could not test my algorithms with Schistocerca gregaria in real time, so it was simulated using the most like web-based resource, Farmville.
My conclusions are the following:
1. Locust spread because they are cute and have big sad eyes that appeal to the mother in all of us, and are willingly adopted by many individuals, particularly older women.
2. These woman will send all their friends and friends of friends, including their children's disinterested friends, gifts of cute lonely locusts.
3. Some will respond, and so spawn new swarms.
These findings may provoke comment in some quarters.
