A few years ago, at a secret location in Arizona, genetically modified pink bollworms -- Pectinophora Gossypiella -- were released to see how they behave in the wild.

Created by Britain's Oxitec, the transgenic bollworms -- they're really caterpillars that become moths -- "behave quite like the untransformed sterile strain," says Greg Simmons,

These farmers practiced conservation and use of a predatory ant, Lepisiota sp., to control cotton bollworms, a practice still used in organic cotton farming in Uganda.
