Abstract
The invention discloses a method for detecting the electrical signal of an insect. The piercing and sucking electrical signal of the insect can be detected so as to research the insect trophic behavior and the transmission mechanism between animals and plants. A static wire is stuck to the back of the insect by conductive adhesive, and a closed circuit is formed by the static wire, an external power supply and an external resistor; the insect pierces and sucks plants to generate biological electromotive force so as to generate current in the circuit; the current generates pressure drop by the resistor; the pressure drop is detected by an amplifier and is supplied to a capture card; the collected data are transmitted to a computer to be stored by the capture card, and waveform is displayed.
Description
Technical field
Patent of the present invention is a kind of method that detects the insect signal of telecommunication, especially detects the thorn of piercing sucking insect and inhales the signal of telecommunication, thus the trophic behaviour of research insect, the impact on photosynthesis of plant, and the mechanism of transmission of virus between animal and plant.
Background technology
Piercing sucking insect majority is the important pests of farm-forestry crop, and these insects directly suck water, affects growth and the output of plant, and the honeydew of its secretion causes mould parasitism, pollutes blade face, affects the quality of photosynthesis and the product of plant.The more important thing is, these insects are communication medias of plant virus, cause the outburst of virus disease.Will effectively control the harm of these piercing sucking insects, just must study their trophic behaviours on plant, screening resistance plant kind, explores mechanism and control approach that their propagate disease.Because piercing sucking insect lancet when taking food inserts in plant corpus, externally be difficult to know the concrete behavior of insect, a kind of method that detects the insect signal of telecommunication of our research is for trophic behaviour and the influence factor thereof of research piercing sucking insect provide a useful instrument.
Summary of the invention
The present invention proposes a kind of method that detects the insect signal of telecommunication, and can detect the thorn of insect and inhale the signal of telecommunication, thus the trophic behaviour of research insect, the mechanism of transmission of virus between animal and plant.
The technical scheme that technical solution problem of the present invention adopts is: insect back is stained with to conductive filament with conducting resinl, then insect is placed on plant, and plant is also stained with to conductive filament with conducting resinl, by external power supply and outer meeting resistance, insect and plant are formed to closed-loop path; Insect thorn is inhaled plant, produce bioelectricity kinetic potential, thereby at closed-loop path generation current, electric current produces pressure drop by resistance, this pressure drop is exaggerated device and detects, also amplifies and supply with capture card, capture card is stored the transfer of data collecting to computer, by signal, process, and on computer display screen, by the insect signal of telecommunication, the mode with waveform shows.
The invention has the beneficial effects as follows: to control plant pest, provide theory and technology scheme.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the inventive method patent is described further.
Fig. 1 is schematic diagram of the present invention.
(1) power supply in Fig. 1, (2) electrode, (3) plant, (4) insect, (5) conductive filament, (6) amplifier, (7) resistance, (8) ground connection, (9) capture card, (10) computer.
Embodiment
In schematic diagram shown in Fig. 1, insect (4) back is stained with to conductive filament (5) with conducting resinl, and power supply (1), electrode (2), plant (3), resistance (7) form closed-loop path, insect (4) thorn is inhaled plant, produces bioelectricity kinetic potential, thereby at loop generation current, electric current produces pressure drop by resistance (7), be exaggerated device (6) and detect, amplify and supply with capture card (9), capture card (9) image data, is transferred to computer (10) storage, display waveform.
Conductive wire can use gold, silver, platinum, such as carbon fiber conductive material, diameter of over 10?-?20 microns, has certain elasticity and toughness, not too big effect insect activity.
Adopt high input impedance amplifier, reduce the impact on closed-loop path electric current; Because bioelectrical signals is generally 40-70 millivolts, so multiplication factor is chosen 50-100 times, output signal is less than 10 volts, facilitates capture card collection to show.
In order to reduce an outer interference, whole device is placed in electrostatic screen cage, whole device ground connection (8); The circuit parts such as amplifier are contained in metal shell, metal shell ground connection (8); Connecting line shielding line.
Claims (4)
1. a method that detects the insect signal of telecommunication, it is characterized in that: insect back is stained with to conductive filament with conducting resinl, then insect is placed on plant, and plant is also stained with to conductive filament with conducting resinl, by external power supply and outer meeting resistance, insect and plant are formed to closed-loop path; Insect thorn is inhaled plant, produce bioelectricity kinetic potential, thereby at closed-loop path generation current, electric current produces pressure drop by resistance, this pressure drop is exaggerated device and detects, also amplifies and supply with capture card, capture card is stored the transfer of data collecting to computer, by signal, process, and on computer display screen, by the insect signal of telecommunication, the mode with waveform shows.
