Abstract

The invention belongs to the technical field of pest control, more specifically to flying insect traps. An insect trap uses an UV light source that effectively attracts and kills insects, dispensing with the need for a second device. The insect trap consists of a chamber (1) with an opening (6) through which insects attracted then killed by the lamp (4) can enter. The chamber (1) comprises a slot (31) through which the tray (3) is inserted. The lamp (4) is fastened by two holders (5) inside the chamber (1). The killed insects fall onto the tray (3), which can be withdrawn for cleaning. The lamp (4) used in the trap can generate UV-C radiation. An active sexual pheromone is applied to the rear wall of the chamber (1).

Description

INSECT TRAP

Technical sector

[001] The present invention patent belongs to the technical sector of pest control equipment, more specifically traps for flying insects, such as mosquitoes, flies and beetles.

State of the art

[002] Pest control is of great importance for human well-being, as it limits the spread of diseases, such as dengue fever. Furthermore, this type of control is also important in industry, for example, in the tobacco industry, where it is important to avoid contact between beetles and tobacco. The use of poisons should be avoided in facilities where the processing of consumable materials takes place, as it poses a risk of contact with humans.

[003] Patent document GB 1 279 196 A, entitled IMPROVEMENTS IN OR RELATING TO INSECT CONTROL anticipates an apparatus equipped with ultraviolet light, to attract insects, which are killed when they come into contact with an electrified grid. The disadvantage of the device in this patent document is the need for an electrified grid, the difficulty in cleaning and sanitizing this grid after long use, in addition to the risk of fire caused by electrification.

[004] Patent document US 2016/000060, entitled INSECT TRAP DEVICE AND METHOD OF USING proposes a device equipped with at least one ultraviolet lamp that has the function of attracting insects to an adhesive surface, where they become trapped and end up being eliminated . The disadvantage of the device in this patent document is the need for materials with adhesive surfaces and their temporary replacement, which requires care and operating costs.

[005] Patent document US 5,365,690 A FLYING INSECT TRAP USINO REFLECTED AND RADIATED LIGHT anticipates the use of ultraviolet radiation in the range of 4 nm to 40 nm to attract insects. However, this device has the disadvantage of being equipped with an adhesive surface, which must be changed periodically, which means higher costs for the end user and more work involved.

[006] Therefore, there are no reports in the scientific literature of insect traps with emitting devices in the UV-C range (200 to 400 nm) intended to attract and kill insects.

Novelty and purpose of the invention

[007] The object of the present invention is an innovative insect trap that employs an ultraviolet light radiation source in the UV-C wave range (200 to 400 nm). This radiation source is efficient in attracting and also killing insects, eliminating the need for a second device to eliminate insects.

[008] Thus, the insect trap of the invention effectively resolves the previously mentioned limitations of the prior art.

[009] The insect trap of the invention preferably consists of a chamber with an opening in the front, through which insects must enter. Just below this entrance, a translucent surface is placed, for example glass or polymeric sheet, which allows ultraviolet light to pass through and attract insects. Said ultraviolet light generates UV-C radiation that has a wavelength in the range of 200 to 400 nm, preferably 254 nm, which is capable of attracting and simultaneously eliminating insects that come into contact with it. Said chamber also has a sliding tray on the lower surface, which is responsible for collecting the killed insects, thus making cleaning the set easier. Thus, it is an advantage of the invention in relation to the state of the art, that there is no need for adhesive surfaces, which must be replaced periodically, which means discomfort for the user and higher cost of use. The use of the sliding tray combined with UV-C ultraviolet light allows the device to have fewer parts, which means lower production and maintenance costs.

[010] The trap optionally includes an insect-attracting pheromone, in the form of a tablet. More specifically, the pheromone may be a synthetic sexual pheromone for attracting the insect Lasioderma serricorne, popularly known as the tobacco bug. Said pheromone tablet is positioned inside the chamber and is mainly composed of serricornine.

Advantages and technical effects of the invention

[011] The insect trap of the invention results in the following advantages and achieves the following technical effects over models present in the prior art:

- Employs a light source of UV-C radiation that attracts and kills insects, making the device simpler and more practical; The traps developed to date use two independent devices, one to attract (light) the other to kill the insects;

- Simplifies the resolution of a common everyday problem, through simpler equipment that uses fewer components, reducing assembly and maintenance costs and electricity consumption;

- Optionally, the trap can be equipped with a pheromone tablet positioned inside the chamber that helps attract insects inside.

List of attached drawings

[012] In order for the present invention to be fully understood and put into practice by any technician in this technological sector, it is now described in a clear, precise and sufficient manner, based on the attached drawings, listed below:

Figure 1 - frontal perspective view of the trap;

Figure 2 - sectional side view of the trap;

Figure 3 - exploded view of the trap;

Figure 4 - side sectional view of a trap option equipped with pheromone.

Model description

[013] Figure 1 exemplifies a preferred form of insect trap that is constructed from a chamber (1), having an opening (6) through which insects can enter, attracted by the lamp (4) and killed by the same lamp (4). The chamber (1) also has a slot (31) where the tray (3) is inserted. Said lamp (4) is fixed via two supports (5) which are fixed inside the chamber (1), and is preferably positioned on the internal face of the glass (2). The insects that are killed fall into the tray (3), which can be removed for cleaning. The lamp (4) used in the trap is capable of generating UV-C radiation, in the wavelength range of 200 to 400 nm, preferably 254 nm.

[014] Figure 1 details in frontal perspective the trap which consists of a chamber (1) with an opening (6) through which the insects enter the trap. In this image it is possible to identify the tray (3), which is mounted on the camera (1 ). We also visualize the translucent external surface (2), exemplifying glass or polymeric sheet.

[015] Figure 2 presents a sectional view of the chamber (1), which shows the positioning of the lamp (4) and the support (5) in relation to the translucent surface (2) and in relation to the opening (6). This way, it is possible to understand how the tray (3) is positioned in relation to the chamber (1) in order to collect the insects killed by the lamp (2).

[016] Figure 3 is an exploded front perspective view, to facilitate understanding the positioning of the translucent surface (2), the supports (5), the lamp (4) and the opening (6). In the same figure 3 we see the tray (3) displaced in relation to the chamber (1) and the slot (31), which shows how it is installed.

[017] Figure 4 illustrates a constructive option for the trap that may have a synthetic sexual pheromone tablet (7) compound for attracting insects, which is positioned inside the chamber (1). More specifically, the pheromone can be of the synthetic sex pheromone class, preferably serricorin, to attract Lasioderma serricorne, popularly known as tobacco bug.

[018] This descriptive report deals with a new insect trap that results in a new technical effect in relation to the state of the art, thus proving its inventive activity, descriptive sufficiency and industrial application, meeting the requirements for granting an invention patent .
