    A new method of instantly identifying passing insects could lead to a way of reducing pesticide use by allowing researchers to develop better targeted attacks.
    The device will feature a laser-thin beam of light that will shine onto an array of phototransistors able to translate light fluctuations into sounds. As an insect flies through the laser beam, the beating of its wings will cause the signal to fluctuate. The signal will then be recorded as an MP3 file and analyzed by a computer program able to differentiate between the wing beats of species and identify the insects with an impressive amount of accuracy.
