Description

Technical Field

[0001] This utility model relates to the field of pest control, and in particular to a device for trapping the oriental fruit fly. Background Technology

[0002] The oriental fruit fly (Bactrocera dorsalis) is a pest widely distributed in tropical and subtropical regions, primarily damaging citrus fruits. Its larvae feed inside the fruit, causing rot, reduced quality, and significant losses to agricultural production. Traditional control methods rely mainly on chemical pesticides, but long-term use not only pollutes the environment but may also lead to increased pesticide resistance in the pest, thus reducing control effectiveness. In recent years, with increasing emphasis on environmental protection and green agriculture, physical trapping devices have gradually become an important alternative.

[0003] Physical trapping typically includes methods such as light attraction, food baiting, and sex pheromone trapping, with sex pheromone trapping being widely used due to its effectiveness. Currently, many traps are also used in conjunction with sex pheromones, but certain problems exist. For example, patent CN213587239U reports a trapping device for the oriental fruit fly, consisting of a sticky umbrella, a attractant bottle, and a hanging rope. The attractant bottle and sticky umbrella need to be replaced frequently and cannot be reused, increasing subsequent investment and labor costs. Patent CN218164060 reports an oriental fruit fly trapping device based on a novel attractant rod, consisting of a base, a attractant rod, a first cylinder, and a second cylinder. The surface of the first cylinder has an entrance; during use, oriental fruit flies enter the first cylinder through the entrance and can easily crawl out through the entrance as well, resulting in poor escape prevention and low trapping efficiency. The threaded connection between the first and second cylinders and the insertion design of the attractant rod are complex, increasing the difficulty of assembly and maintenance; the light ring requires an external power supply, increasing the device's energy consumption and operating costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fruit fly trapping device that is simple in structure, low in cost, highly efficient in trapping and easy to use.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A trapping device for oriental fruit flies, characterized in that it includes a hook, an upper canister and an insect collection bottle, an insect inlet hole on the side wall of the upper canister, the hook being located at the top center of the upper canister, the lower end of the upper canister being connected to the upper end of the insect collection bottle, an insect collection channel being provided at the connection between the lower end of the upper canister and the upper end of the insect collection bottle, an escape-prevention funnel being provided at the insect collection channel, and an insect collection inlet being provided on the side wall of the escape-prevention funnel.

[0007] This utility model is further improved by providing an escape-proof sleeve at the insect inlet hole on the inner side wall of the upper tank.

[0008] This invention is further improved by providing a crawling platform on the lower side of the insect inlet hole on the outer wall of the upper tank. The attracted oriental fruit flies can first land on the upper side of the crawling platform and then crawl in through the insect inlet hole, facilitating their rapid entry and improving trapping efficiency.

[0009] Preferably, the upper tank includes a sleeve-shaped main body, an upper cover plate, and a conical lower cover plate. The upper cover plate is fixedly connected to the upper end of the main body, and the upper end of the lower cover plate is fixedly connected to the lower end of the main body. A connecting ring with external threads is provided on the lower end of the lower cover plate. The insect collecting bottle has internal threads at its mouth, and the insect collecting bottle is installed on the lower end of the upper tank via the internal threads at its mouth and the external threads on the connecting ring. The connection between the connecting ring and the inner side of the mouth of the insect collecting bottle forms an insect collecting channel connecting the upper tank and the insect collecting bottle.

[0010] Preferably, the upper tank sidewall is provided with at least two circumferential insect inlet holes, each circumferential insect inlet hole including at least three circumferentially evenly distributed insect inlet holes; a ring-shaped crawling platform is provided below each circumferential insect inlet hole. The structure is simple and easy to process.

[0011] Preferably, the escape-proof sleeve is conical, with the inner diameter of its large-diameter end matching the diameter of the insect inlet hole. The large-diameter end of the sleeve is fixedly connected to the inner wall of the upper tank, and the axis of the sleeve coincides with the axis of the corresponding insect inlet hole. This makes it less likely for fruit flies entering the upper tank to penetrate through the small-diameter end of the sleeve, resulting in better escape prevention.

[0012] Preferably, the inlet hole is frustum-shaped, with the diameter of the inlet hole inside the upper can being smaller than the diameter of the inlet hole outside the upper can. This facilitates the entry of the oriental fruit fly.

[0013] Preferably, the outer diameter of the upper opening of the anti-escape funnel is slightly larger than the inner diameter of the lower port of the lower cover plate, and the upper end of the anti-escape funnel is fixed at the lower port of the lower cover plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) Simple structure and easy to manufacture. This device consists of a hook, an upper tank with openings, an escape-proof funnel, and an insect collection bottle. Compared with complex mechanical or electronic trapping devices, this device does not require complex processing technology and expensive materials, making it suitable for large-scale production and promotion.

[0016] (2) High trapping efficiency. By adding attractants to the insect collection bottle, the oriental fruit fly can be effectively attracted into the device. The design of the escape-proof sleeve and escape-proof funnel can prevent the pest from escaping, significantly improving the trapping efficiency.

[0017] (3) The hanging is simple and the maintenance cost is low. Compared with sticky traps and other trapping devices, it can trap more oriental fruit flies; the trapping device can be used continuously as long as the lure core is replaced and the insect collection bottle is cleaned.

[0022] To make the technical solution of this utility model clearer, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, the oriental fruit fly trapping device of this embodiment includes a hook 1, an upper canister, and an insect collection bottle 9. An insect inlet hole 10 is provided on the side wall of the upper canister. The hook 1 is located at the top center of the upper canister. The lower end of the upper canister is connected to the upper end of the insect collection bottle 9. An insect collection channel is provided at the connection between the lower end of the upper canister and the upper end of the insect collection bottle. An escape-proof sleeve 2 is provided at the insect inlet hole 10 on the inner side wall of the upper canister. Figure 1 , Figure 4 As can be seen, the escape-proof sleeve 2 is conical in shape. The inner diameter of the large-diameter end 2-2 of the escape-proof sleeve 2 is the same as the diameter of the insect inlet hole 10. The large-diameter end 2-2 of the escape-proof sleeve 2 is fixedly connected to the inner side wall of the upper tank. The axis of the escape-proof sleeve 2 coincides with the axis of the corresponding insect inlet hole 10. The oriental fruit flies entering the upper tank are less likely to crawl in through the small-diameter end of the escape-proof sleeve 2, resulting in a better escape-proof effect. The insect collection channel is equipped with an escape-proof funnel 7 whose diameter gradually decreases from top to bottom. The escape-proof funnel 7 is hollow and conical in shape. The side wall of the escape-proof funnel 7 is equipped with an insect collection inlet 8.

[0025] This embodiment is further improved by providing at least two circumferential insect inlet holes on the side wall of the upper tank, each circumferential insect inlet hole consisting of 10 evenly distributed circumferential insect inlet holes 10; a ring-shaped crawling platform 5 is provided below each circumferential insect inlet hole; the attracted oriental fruit flies can first land on the crawling platform 5, and then crawl into the insect inlet hole 10, which facilitates the oriental fruit flies to quickly enter the insect inlet hole 10, thereby improving the trapping efficiency. The ring-shaped crawling platform 5 has a simple structure and is easy to process. The upper can body includes a sleeve-shaped can body 4, an upper cover plate 3, and a conical lower cover plate 6. The upper cover plate 3 is fixedly connected to the upper end of the can body 4, and the upper end of the conical lower cover plate 6 is fixedly connected to the lower end of the can body 4. A connecting ring 12 is provided on the lower end of the conical lower cover plate 6, and the connecting ring 12 has external threads. The insect collecting bottle 9 has internal threads at its mouth 11, and the insect collecting bottle 9 is installed on the lower end of the upper can body through the internal threads at the mouth 11 and the external threads on the connecting ring 12. It is simple and convenient to assemble and disassemble during use. The outer diameter of the upper opening of the escape-proof funnel 7 is slightly larger than the inner diameter of the lower end of the lower cover plate 6, and the upper end of the escape-proof funnel 7 is fixed to the lower end of the lower cover plate. The insect collecting inlet 8 on the escape-proof funnel 7 is located inside the insect collecting bottle 9. This can prevent the oriental fruit flies that enter the insect collecting bottle from flying back into the upper can body, further reducing the possibility of escape.

[0026] In use, the trapping device is suspended from fruit tree branches using hooks. Attracted by the sex pheromones inside the collection bottle, oriental fruit flies fly towards the device, landing on the crawling platform on the outside of the upper canister. They then crawl into the upper canister through the inlet hole and escape-proof sleeve on the side wall, running along the conical structure at the bottom to the escape-proof funnel, and finally entering the collection bottle through the collection inlet. While the oriental fruit flies can easily enter through the inlet hole, they have difficulty flying out, effectively preventing escape. The smooth inner wall of the collection bottle makes it difficult to climb, and together with the escape-proof sleeve and funnel, it effectively prevents the oriental fruit flies from escaping. The collection bottle is completely transparent, allowing a clear view of the approximate number of oriental fruit flies inside, making cleaning or replacing the bottle very easy. Regularly checking the collection bottle, cleaning the captured oriental fruit flies, and replacing the attractant ensures continuous trapping.

[0027] Example 2

[0028] like Figure 3 As shown, in this embodiment, the upper cover plate 3 of the upper tank is an arched shape with a certain curvature, which can effectively prevent rainwater accumulation and has a certain wind resistance effect; the hook is fixed at the highest point of the arch of the upper cover plate 3, and the trapping device is suspended on the branches of the fruit tree through the hook; the oriental fruit fly is attracted by the sex pheromone in the insect collection bottle; the insect inlet hole is truncated cone-shaped, and the diameter of the insect inlet hole 10 on the inner side of the upper tank is smaller than the diameter of the insect inlet hole on the outer side of the upper tank, which is more conducive to the oriental fruit fly crawling in. Other structures are the same as in embodiment 1, and will not be described again.

[0029] The fruit fly trapping device of this invention has a simple structure and is easy to use. It can effectively trap fruit flies, reduce the damage of pests to citrus fruits, and has good application prospects.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
