Caffeinated fruit flies help identify potential genes affecting insecticide resistance

To understand genetic mechanisms underlying insecticide resistance, scientists employed fruit flies and caffeine, a stimulant surrogate for xenobiotics in lab studies on resistance. Crop pests are capable of outwitting the chemical compounds known as xenobiotics that are devised to kill them. This development of resistance to insecticides is a serious problem because it threatens crop production and thereby can influence the availability and costs of many foods as well as the economy.
