Description

Technical Field

[0001] This utility model relates to the field of insect-attracting and insect-killing equipment, and in particular to a multifunctional insect-attracting and insect-killing tower for tobacco fields. Background Technology

[0002] Current methods of pest control in the field generally utilize insect attraction to light, sex pheromones, sound, and food. Common methods of pest control in the field include light attraction, sex attraction, and food attraction.

[0003] Insect compound eyes consist of multiple ommatidia, each surrounded by a layer of pigment. This pigment can be dark, cloudy, or white, determining whether an insect is diurnal, nocturnal, or engages in mixed activities. Utilizing these light characteristics, frequency-vibration insecticidal lamps can be programmed to protect predators by focusing their light waves within a specific range. Based on the trichromatic principle, when the lamp is shone on a yellow object, the light turns yellow-green at night. This attracts large numbers of yellow-loving pests to the lamp, while reducing the attraction of beneficial insects like lacewings and ladybugs that prefer green, significantly increasing the pest trapping rate and reducing the beneficial-to-pest ratio. Scent: This refers to the principle of sex pheromones. Practical experience shows that the presence of live insects in the collection bag attracts more of the same type of insect, proving that the sex pheromones released by live insects can increase the trapping rate.

[0004] In tobacco cultivation, based on the concept of shared resource groups and the feeding methods of these pests, they are divided into five groups: underground pests (root-cutting groups), piercing-sucking groups, leaf-eating groups, stem-boring groups, and leaf-mining groups. The root-cutting group includes: small cutworms, yellow cutworms, large cutworms, click beetles, slender-breasted click beetles, net-mesh ground beetles, and two-striped soil miners; the piercing-sucking group includes: tobacco aphids, tobacco whiteflies, tobacco thrips, spotted stink bugs, and tobacco mirid bugs; the leaf-eating group includes: tobacco bollworms, cotton bollworms, beet armyworms, cabbage armyworms, short-horned grasshoppers, slugs, and snails; the stem-boring group contains only one species, the tobacco stem borer; and the leaf-mining group includes: the tobacco leafminer and the South American leafminer.

[0005] Among the most common pests that have a significant impact on tobacco are: cutworms, wireworms, and barn beetles; tobacco aphids, whiteflies, and spotted stink bugs; tobacco bollworms, beet armyworms, and tobacco leaf miners.

[0006] Phototaxis: Primarily based on the phototaxis of insects. For ultraviolet light, commonly used methods include insecticidal lamps, solar-powered insecticidal lamps, solar-powered frequency-vibration insecticidal lamps, and insect-attracting boards (commonly yellow or blue boards). Examples include solar-powered frequency-vibration insecticidal lamps, aphid-attracting yellow boards, and tobacco thrips-attracting blue boards commonly used in tobacco fields. Sex pheromones: The principle behind using sex pheromones to attract and kill pests (moths and butterflies) is to utilize communication between insects. After using sex pheromones, male insects are generally attracted to mate (sex pheromones are mostly secreted and released by female insects), thus achieving the desired killing effect. Commonly used sex pheromones are for the beet armyworm and tobacco budworm. Food pheromones: Primarily utilizing the attraction to odors and food, sugar-vinegar solutions are commonly used for controlling underground pests in tobacco.

[0007] Generally speaking, color-attracting, sex-attracting, and food-attracting methods are implemented separately in the field, without a single integrated multi-functional insect-attracting device that combines all three principles. Fixed insecticidal lamps in the field require fixed foundations (cement foundations) for installation, which can occupy or damage farmland and is costly. Hanging aphid-attracting boards and sex pheromones in the field are often temporary, using special support poles or bamboo poles, which offer poor support and are easily affected by wind and rain in the field, making them difficult to fix or replace, resulting in poor insect-attracting and killing effects. Food-attracting methods are limited by environmental conditions, greatly affected by rain and temperature, attracting insects but not effectively trapping them, and also pose a risk of poisoning other animals, leading to low utilization rates in the field. The conventional use of these three methods suffers from high labor costs, significant resource waste, poor insect-attracting and killing effects, significant environmental influences, and difficulties in replacement and cleaning.

[0008] Common pests in tobacco field production mainly consist of "three insects and four diseases." The insects are primarily underground pests, mainly cutworms; tobacco aphids, which transmit viral diseases; and tobacco budworms, which damage tobacco leaves in the mid-to-late stages. A combination of light traps, color traps, sex traps, and food traps can be used to improve the efficiency of attracting and killing these pests. Summary of the Invention

[0041] Example 1:

[0042] like Figure 1 As shown, a multifunctional insect-attracting and killing tower for tobacco fields includes a support column 1. The lower end of the support column 1 is fixed in the soil of the tobacco field. In actual use, the support column 1 can be a single or multiple columns, and adopts a telescopic column or tripod design. The lower end of the support column 1 can also be equipped with a multi-branched structure for easy insertion into the soil for fixation.

[0043] The supporting column 1 has an insect collection tube 2 at its upper end, and a light-attracting mechanism is located at the upper end of the insect collection tube 2. The distribution height of the light-attracting mechanism is 45-50cm. The light-attracting mechanism 3 includes a lamp holder 301 set on the upper side of the insect collection tube 2, and several insect-attracting lamps 302 are set on the lamp holder 301. An electric shock net 303 is set between the lamp holder 301 and the insect collection tube 2. A storage battery supplies power to the insect-attracting lamps 302 and the electric shock net 303. In actual use, a solar panel can be set on the upper end of the lamp holder 301 to charge the storage battery.

[0044] The insect collection tube 2 has an inclined insect guide plate 4 at the upper opening. An inlet is provided between the insect guide plate 4 and the side wall of the insect collection tube 2. The insects that are electrocuted are guided into the insect collection tube 2 by the insect guide plate 4. At the same time, the insect guide plate 4 partially covers the upper part of the insect collection tube 2 to prevent the surviving insects from escaping.

[0045] The lower side wall of the insect collecting tube 2 is provided with an insect extraction port 201. The pests collected in the insect collecting tube 2 are taken out through the insect extraction port 201. The insect extraction port 201 can be covered by a cover plate, and the cover plate is connected to the insect collecting tube 2 by bolts or hinges.

[0046] Example 2:

[0047] Unlike Embodiment 1, the insect collecting tube 2 is provided with a partition plate 5 to separate the insect collecting tube 2 into a color-attracting area 202 and a sex-attracting area 203. Both the color-attracting area 202 and the sex-attracting area 203 are hollow semi-cylinders.

[0048] The insect guide plate 4 is set at the upper end of the color-attracting area 202, and the insect collection port 201 is set on the corresponding cylinder wall of the color-attracting area 202. The upper end of the sex-attracting area 203 is provided with an inclined insect collection plate 6, with the end of the insect collection plate 6 closer to the color-attracting area 202 being lower than the other end. The inclination angle of the insect guide plate 4 and the insect collection plate 6 is 30~45°.

[0049] The insect-guiding plate 4 and the insect-collecting plate 6 are equipped with reflective lenses on their upper sides. By setting reflective lenses, the light can be enhanced, which helps to expand the diffused light range at night and improve the insect-attracting effect.

[0050] like Figures 2-4 As shown, the insect-collecting port 201 is provided with an insect-sticking color plate 7, with the insect-sticking surface of the insect-sticking color plate 7 set on the outer side. The cylinder wall corresponding to the insect-collecting port 201 is provided with a card slot 204 for inserting both ends of the insect-sticking color plate 7, that is, both ends of the insect-sticking color plate 7 are inserted into the card slot 204 on both sides of the insect-collecting port 201.

[0051] Multiple sets of fixing protrusions 205 are provided on the outer side of the insect collecting tube 2 along the card slot 204. In this embodiment, each set of card slot 204 is provided with 3 sets of fixing protrusions 205. The end of the elastic rope 8 is hung on the fixing protrusion 205 and set on the outer side of the sticky insect color board 7. The sticky insect color board 7 is fixed by setting the elastic rope 8. The elastic rope 8 can also be fixed by springs or the like.

[0052] Preferably, the insect-removing opening 201 is provided with a locking protrusion 206, and the lower end of the sticky insect color plate 7 is provided with a locking slot that cooperates with the locking protrusion 206. Through the cooperation of the locking protrusion 206 and the locking slot of the sticky insect color plate 7, the sticky insect color plate 7 can be prevented from moving left and right, thereby improving the installation stability of the sticky insect color plate 7.

[0053] The above structure facilitates the installation and replacement of the sticky insect color board 7. At the same time, the sticky insect color board 7 seals the insect collection port 201 to prevent the pests collected in the insect collection tube 2 from escaping because they are not dead.

[0054] In the market, the standard size of sticky insect sticky boards is 20cm*25cm. The insect-removing opening 201 can be set to a height of 20cm and a length of slightly less than 25cm, so that both ends of the sticky insect sticky board 7 can be inserted into the card slots 204 at both ends of the insect-removing opening 201.

[0055] Example 3:

[0056] Compared with Example 2, further, such as Figure 1 and 5As shown, the cylinder wall corresponding to the pheromone trap 203 is provided with an installation port for installing the lure core 9. The lure core 9 is inserted into the installation port by installation on one side. The lure core 9 is provided with an insect-attracting hole 901 for insects to enter. The insect-attracting hole 901 is a cross-shaped internal protrusion hole, which is conducive to the entry of pests and not conducive to the crawling out of pests. The lure core 9 contains a pheromone. The bottom of the cylinder corresponding to the pheromone trap 203 is provided with an insect discharge port, and a collection bag 10 is set at the insect discharge port.

[0057] The upper 15-20cm section of the pheromone trapping area 203 is the pheromone collection area, with insect-attracting holes 901 on the side. The lower 20cm section is the insect collection chamber. There is no partition between the pheromone trapping area and the insect collection chamber, allowing the collection chamber to better utilize its dispersing biological characteristics and improve pheromone trapping efficiency. The insect discharge port corresponding to the pheromone trapping area 203 can be designed with a semi-circular flap or a pin-type base plate for easy opening and closing.

[0058] Example 4:

[0059] Unlike Examples 1-3, such as Figure 6 As shown, the lower end of the supporting column 1 is provided with a food attracting device 11. The food attracting device 11 includes an insect attracting cage 1101 and an insect collection box 1102. The insect attracting cage 1101 has a trapezoidal structure. The inclined surface of the insect attracting cage 1101 is provided with a one-way insect attracting hole 1103. The one-way insect attracting hole 1103 is a transverse single-sided internal punch hole, which is conducive to the crawling of pests and at the same time reduces the entry of rainwater.

[0060] In practical use, the insect trap 1101 can be made of transparent material for easy observation.

[0061] The insect collection box 1102 can be fitted with a detachable insect collection net, which makes it easy to clean up the killed pests.

[0062] The insect trap 1101 is positioned above the insect collection box 1102, which is located below ground level. The insect trap 1101 is positioned above ground level, meaning the cavity formed by the insect trap 1101 and the insect collection box 1102 is partially submerged. Both the insect trap 1101 and the insect collection box 1102 have through holes for the support column 1 to pass through. The support column 1 has external threads on its outer side. The upper side of the insect trap 1101 and the lower side of the insect collection box 1102 are equipped with fixing nuts 1104 that mate with the support column 1. By using two sets of fixing nuts 1104, the insect trap 1101 is pressed against the upper side of the insect collection box 1102. In practical use, the outer edge of the insect trap 1101 covers and extends beyond the area of ​​the insect collection box 1102, with the outer edge of the insect trap 1101 inserted below the soil. A counterweight bag, which can be a geotextile bag, covers the upper side of the outer edge of the insect trap 1101.

[0063] A feeding platform 1105 is provided on the outside of the support column 1. The feeding platform 1105 is located between the insect trap 1101 and the insect collection box 1102. Insect attractant food is provided on the feeding platform 1105. The insect attractant food can be solid insect attractant food or liquid insect attractant food.

[0064] The insect trap 1101 and the insect collection box 1102 are filled with fiber 1106, which is impregnated with insecticide liquid or insecticide powder. The fiber 1106 covers the feeding platform 1105 and occupies 70-80% of the space of the insect trap 1101, shortening the flight space and controlling the escape of flying insects.

[0065] Preferably, the support column 1 is a hollow structure, and the outside of the support column 1 is provided with a through hole for the liquid addition pipe 1107 to pass through. The liquid addition pipe 1107 is connected to the liquid external bottle 1108. The liquid addition pipe 1107 is provided with a valve, and the addition of liquid is controlled by the valve. Liquid insect attractant food is provided in the liquid external bottle 1108.

[0066] A solid feeding port 102 is provided on one side of the support column 1, and a food attracting platform 1105 is provided on the cross-section of the support column 1. A feeding outlet 101 is provided on the side wall of the support column 1 relative to the food attracting platform 1105.

[0067] The addition of liquid pipe 1107 and external liquid bottle 1108 facilitates the replenishment of liquid insect attractant food, while the addition of solid feed port 102 facilitates the replenishment of solid insect attractant food, thus eliminating the need to disassemble the insect attractant cage 1101 when replenishing the insect attractant food.

[0068] In this embodiment, the height of the light-attracting zone where the light-attracting mechanism is located is 45-50cm, the height of the color-attracting zone and the sex-attracting zone where the insect collection tube 2 is located is 30-40cm, the height of the insect-attracting cage 1101 in the food-attracting and killing zone is about 30cm, the upper bottom diameter is 25cm, the lower bottom diameter is 35-40cm, the height of the insect collection box 1102 is 15cm, and the diameter is about 30cm.
