Coffee drinkers, take note! The coffee bean's number one enemy, a bug that practices incest as a way of life and goes by the name of Hypothenemus hampei, or the coffee berry borer, can now outwit its archenemy, the pesticide endosulfan. Although investigators believe they have figured out the insect's secret genetic weapon, they have yet to defuse it.

In 1989, scientists discovered that many coffee berry borers on the South Pacific Island of New Caledonia tolerate endosulfan, the most common insecticide used against them. Unlike many other chemicals, this fumigant reaches inside ...
