Lux, S.: The design of a phonoactograph suitable for study pn the influence of pheromones on. insect mobility. Acta physiol, pol., 1988, 39(5-6): 513 -516. An instrument for recording changes in insect mobility under the influence of pheromone was described. The Instrument was named ,.phonoactograph" because the intensity of rustle, maide by insects was utilized as a correlate of their movement. The Colorado beetle males exposed to the action of the female odour increased their mobility significantly.
