Sugar is Death to Aphids

A treat for humans, sugar can be deadly to aphids.

Agricultural researchers are now exploiting this vulnerability as an insecticide-free way to control insect pests.

"There is an urgent need for new strategies for insect control, because insects are developing resistance to traditional broad spectrum insecticides," says professor Angela Douglas of Cornell University.

Douglas and fellow scientist Georg Jander are genetically engineering plants to protect themselves by increasing the sugar in their sap.
