ABSTRACT:
An apparatus for use in monitoring the numbers of a selected species of insect comprising one or more traps into which is put a synthesized pheromone to attract that particular insect. Each trap has a grille comprising a plurality of bars between which is applied a high voltage by means of a high voltage generator, so that when an insect of the selected species tries to enter the trap it touches adjacent bars and is electrocuted by the electric discharge between them. This discharge is detected by a discharge detector connected to the trap and the detector passes a signal to a transmitter which transmits it to a central receiver equipped with a discriminator for ignoring signals other than those from the transmitter and for passing the signals representing discharges to a pulse counter whereby a total of the number of insects trapped in a given time can be obtained at a central station without visiting each trap. An astable circuit, which is interposed between the high voltage generator and a portable voltage source such as an accumulator, operates to feed the high voltage generator from a battery at spaced intervals so as to lengthen the duration of the charge of the battery and therefore the duration of efficient operation of the device. The high voltage generator is capable of providing the high voltage even during those periods in which the astable circuit cuts off the supply from the battery. The signal transmitted to the central receiver can be a coded signal.
