Abstract

Abstract An apparatus for use in monitoring the numbers of a selected species of insect comprises 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 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 157 words
A device for use in keeping insect infestations under control, said device comprising: at least one trap, electrical conductor means on said at least one trap, a high tension generator, said electrical conductor means being connected across the output of said high tension generator and being so formed as to produce an electrical discharge when an insect above a given size comes into contact with the said electrical conductor means, radio transmitter means, discharge detector means operable to detect electrical discharges across said electrical conductor means and to enable, in response thereto operation of said radio transmitter means, radio receiver means for receiving signals transmitted by said radio transmitter means, and an impulse counter means connected to the output of said radio receiver means, said impulse counter means operating to count each time said transmitter means is operated, whereby to provide an indication, at a location remote from said trap, of the number of insects trapped thereby.
Claim 2
Independent Claim 157 words
A device for use in keeping insect infestations under control, said device comprising: at least one trap, electrical conductor means on said at least one trap, a high tension generator, said electrical conductor means being connected across the output of said high tension generator and being so formed as to produce an electrical discharge when an insect above a given size comes into contact with the said electrical conductor means, radio transmitter means, discharge detector means operable to detect electrical discharges across said electrical conductor means and to enable, in response thereto operation of said radio transmitter means, radio receiver means for receiving signals transmitted by said radio transmitter means, and an impulse counter means connected to the output of said radio receiver means, said impulse counter means operating to count each time said transmitter means is operated, whereby to provide an indication, at a location remote from said trap, of the number of insects trapped thereby.
Claim 3
Dependent Claim 97 words
The device of claim 1, wherein there is provided a discriminator device connected between said radio receiver and said impulse counter, said discriminator device comprising: a timer circuit the input of which is connected directly to the output of said radio receiver, and a gating device connected to the output of said radio receiver and to the output of said timer circuit, said gating device operating to pass the output signal from said radio receiver to said impulse counter only if the duration of said output signal is longer than a time determined by said timer circuit.
Claim 4
Dependent Claim 14 words
The device of claim 2, wherein said gating device is a logic AND gate.
Claim 5
Dependent Claim 55 words
The device of claim 1, wherein said at least one trap is constituted by a casing having at least one access opening; said at least one access opening being protected by a grille of parallel bars, adjacent bars being connected electrically to opposite terminals of said high tension generator and constituting said electrical conductor means.
