Description

Insect capturing device

Technical Field

The invention belongs to the technical field of biology, and particularly relates to an insect capturing device.

Background

Insects are biological species which are widely distributed in nature and are closely related to the production and life of people. Entomologists have discovered many specific habits of insects, among which the phototaxis of insects is well known. In productive life, a large number of insect species are defined as pests which have direct or indirect adverse effects on us, such as reduced yield of crops, uncontrollable and contaminated fermentation processes, spread of diseases, and the like. For pests, physical, chemical, biological and other methods are used for controlling pests, and the purpose is to use a large amount of pesticides. However, in the current state of the art, we have recognized that the use of chemical pesticides can have serious and complex consequences, such as pesticide residue, soil, air and water pollution, etc., which have a major impact on the natural environment. However, the prior biotechnology is not mature enough and cannot effectively control pests. Therefore, physical pest killing techniques are receiving increasing attention.

In order to realize the killing, monitoring and prevention of diseases and pests, the prior common mode comprises the following steps: typically using a hand-held insect net or insect killing light. But are caught with hand-held insect nets and are easily disturbed by human conditions. The most common insecticidal lamp is based on insect phototaxis and high-tension electricity principle, utilizes light source (50) to attract the insect, and the high-pressure insecticidal grid outside light source (50) is touched to insect to be close to light source (50), leads to the insect to be killed in the twinkling of an eye. If the existing insect-killing lamp is adopted for capturing, the incomplete insect residues under the action of the high-voltage grid are easily caused, and the difficulty is caused for classifying and counting the quantity. In addition, in the conventional insecticidal lamp, the light source (50) spectrum is basically single and cannot be changed. We have found through research that: (1) different kinds of insects respond differently to the light sources (50), and the light sources (50) of different spectrum types have different insect attracting effects; (2) in the same region, insects are often not single but various and coexist, the relationship among the insects is complex, the insects may be symbiotic or natural enemy, and the understanding of regional insect distribution characteristics is an important basic work for prevention and treatment; (3) the proportion of beneficial insects and pests is reasonably controlled, and the loss can be reduced to the maximum extent.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in figures 1 and 2, the invention discloses an insect capturing device, which comprises a capturing cavity 1, wherein the front end of the capturing cavity 1 is open, and a light source combination 50 is arranged at the rear end of the capturing cavity 1. A convex lens 2 is arranged in the inner cavity of the capturer cavity 1 and close to the light source assembly 50, and the light beams emitted by the light source assembly 50 are adjusted by the convex lens 2. It should be noted that: the simplest light source assembly 50 is shown in fig. 1, and includes a main light source 4 and a wire 5, and the wire 5 is used to supply power to the main light source 4 and control the brightness and the operating state of the main light source 4. The main light source 4 can be an energy-saving lamp, a white LED or a light source body formed by combination, and the proper main light source 4 is selected according to the phototaxis of different insects.

The trap cavity 1 is provided with a through hole at a position close to the convex lens 2, the through hole is connected with a collector cavity 8, and the inner cavity of the trap cavity 1 is communicated with the collector cavity 8 through the through hole. The perforation is provided with a pair of elastic membranes 6 which are mutually covered, the elastic membranes 6 are arranged at the upper end part of the collector cavity 8, and the perforation is sealed by the elastic membranes 6. After the upper elastic membrane 6 and the lower elastic membrane 6 are mutually covered, the through hole is sealed; however, when external suction is applied, and the external suction is greater than the elastic force of the elastic membrane 6, the two elastic membranes 6 covering each other are opened, so that insects can enter the collector cavity 8 through the perforations.

The collector cavity 8 is respectively communicated with an air extractor and a asphyxia gas generator through a pipeline 11, the air extractor is used for realizing the unidirectional extraction of air in the collector cavity 8, and the asphyxia gas generator is used for filling the collector cavity 8 with asphyxia gas.

The principle underlying the present solution is as follows, as indicated by the arrows in fig. 1 for the collection path of the insects through the trap chamber 1 to the collector chamber 8: the insects are attracted by the primary light source 4 and enter the trap chamber 1, and the suction device is activated, causing by the suction device, through the negative pressure, the pair of elastic membranes 6, which are hidden from each other, to open, causing the insects to enter or be sucked inside the trap chamber 8 through the perforations. When insects enter the interior of the collector chamber 8, the air extractor stops working, and the asphyxiant gas generator charges the asphyxiant gas into the collector chamber 8 to kill the insects and maintain the integrity of the insects in the collector chamber 8 for research and analysis.

As an optimization, the front end of the trapper cavity 1 in the scheme is diffused outwards to form a horn mouth shape, so that insects can smoothly enter the trapper cavity 1. Meanwhile, in the optimization scheme: the collector chamber 8 comprises a bottom cover 10, the bottom cover 10 is the bottom of the lower chamber, and the bottom cover 10 is detachably connected with the collector chamber 8, so that the whole insects can be taken out of the collector chamber 8. As only the bottom cover 10 needs to be removed to remove the insects from the interior of the collector chamber 8.

In the scheme, a collector port 8a is arranged in the collector cavity 8, the collector port 8a divides the interior of the collector cavity 8 into an upper cavity and a lower cavity, a leak hole is formed in the collector port 8a, and the upper cavity and the lower cavity are communicated through the leak hole; the upper surface of the collector opening 8a is inclined towards the leak hole, so that insects can conveniently gather towards the leak hole and fall into the lower cavity through the leak hole.

The suffocation gas generator is communicated with the lower cavity, the electromagnetic valve 12 is arranged on the pipeline 11 connected with the suffocation gas generator, the gas concentration sensor 13 is arranged in the lower cavity of the collector cavity, the gas concentration sensor 13 is electrically connected with the electromagnetic valve 12, the concentration of the suffocation gas in the lower cavity is detected by the gas concentration sensor 13, the pipeline 11 connected with the suffocation gas generator is opened by controlling the electromagnetic valve 12, and the concentration value of the suffocation gas in the lower cavity is increased. Over time, both the struggling of the insects and the movement of the piston cause a reduction in the concentration of the asphyxiating gas inside the collector chamber 8. The concentration is detected by a gas concentration sensor 13, when the concentration is lower than 90%, an electromagnetic valve 12 is automatically opened, and the suffocation gas generator fills the suffocation gas into the collector cavity 8 through a pipeline 11 so as to meet the concentration required by killing insects. When the concentration reaches 99%, the electromagnetic valve 12 is automatically closed, and the asphyxia gas generator can not fill the asphyxia gas into the collector cavity 8 any more.
