Attract and destroy

SEMIOCHEMICALS that modify insect behaviour could aid integrated pest management, IACR-Rothamsted work shows. They can be used to attract pests like aphids into trap crop areas, where they can be destroyed with biological agents or pesticides. The crop can also be protected by semiochemicals with a repellent or anti-feedant effect. This could eventually be genetically engineered into crops. &#42
