Description

Technical Field

[0001] The utility model relates to a female fly trap for Diptera flies. Background Art

[0002] Diptera is a large order, and many species of flies such as fruit flies are important economic pests that seriously damage fruits, vegetables and wild crops. Fruit flies cause damage in two ways. First, female adults lay eggs, causing mechanical damage to the fruit epidermis, and the glue flowing out of the wound triggers the invasion and infection of pathogenic microorganisms. Then, after the larvae hatch from the eggs, they live in the fruit and feed on the pulp, causing the fruit to rot and fall, but the main damage is caused by the larvae. Therefore, the root cause of fruit fly damage is the female insects. If the female insects can be controlled, the damage of fruit fly pests can be completely solved from the root. The existing fruit fly trap base does not have an insect inlet, so that female insects cannot be trapped, or the fruit fly trap base has only one large insect inlet, and the trapped insects can come and go freely, thus there is a problem of low trapping efficiency. Content of the Utility Model

[0003] The utility model makes improvements to the above-mentioned existing technical problems, that is, the technical problem to be solved by the utility model is to provide a female fly trap for Diptera flies, with reasonable design and improved trapping efficiency.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is: a female fly trap for Diptera flies, including a cylindrical base with an open top, a transparent top cover is covered on the upper end of the base, the transparent top cover and the base are detachably connected, and the bottom of the base is provided with a plurality of insect inlet channels extending upward into the interior of the base. The insect inlet channels are in a conical shape with a diameter gradually decreasing from bottom to top, and both the upper and lower ends of the insect inlet channels are open.

[0005] Further, a plurality of insect inlets are evenly distributed in a circumferential manner on the circumferential side wall of the transparent top cover.

[0006] Further, an insect inlet tube is inserted through each insect inlet. The outer end of the insect inlet tube is clamped in the insect inlet, and the insect inlet tube is in a conical shape with a diameter gradually decreasing from outside to inside.

[0007] Further, two circles of annular protrusions are arranged on the outer peripheral side surface of the outer end of the insect inlet tube, and an annular clamping groove for clamping on the peripheral side part of the insect inlet is formed between the two circles of annular protrusions.

[0008] Further, the insect inlet tube is made of white transparent material.

[0009] Further, a hanging hook hole is arranged on the top of the transparent top cover.

[0010] Further, the transparent top cover is in a shape of a bamboo hat.

[0011] Further, the inner diameter of the lower port of the transparent top cover is larger than the outer diameter of the top opening of the base. A number of horizontal L-shaped slots are evenly distributed around the circumferential side wall at the lower end of the transparent top cover; a number of clamping protrusions are evenly distributed around the circumferential side wall at the upper end of the base. The positions of the number of clamping protrusions correspond to those of the number of L-shaped slots, and the corresponding clamping protrusions are inserted into the horizontal sections of the L-shaped slots.

[0012] Further, the bottom surface of the base is a plane.

[0013] Further, the base is made of yellow opaque material.

[0014] Compared with the prior art, the present utility model has the following effects: The present utility model is reasonably designed. By arranging a number of conical insect-entering channels that protrude into the base inside the base, after using the number of insect-entering channels to lure female insects into the base, due to phototaxis, the female insects will continuously gather towards the top of the transparent top cover, further reducing the risk of escape and greatly improving the trapping efficiency.

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] As Figures 1 to 11 shown, a female - fly trap for Diptera flies in the present utility model includes a cylindrical base 1 with an open top. The interior of the base 1 is used to place a trapping agent or trapping liquid. A transparent top cover 2 is covered on the upper end of the base 1, and the transparent top cover 2 is detachably connected to the base 1. A plurality of insect - inlet channels 3 extending upward into the interior of the base are provided at the bottom of the base 1. The insect - inlet channels 3 are in a conical shape with a diameter gradually decreasing from bottom to top. Both the upper and lower ends of the insect - inlet channels 3 are open, so as to facilitate female flies to enter the interior of the base along the insect - inlet channels. This design utilizes the biological characteristics of Diptera flies. By providing a plurality of conical insect - inlet channels protruding into the interior of the base, after the female flies are attracted into the interior of the base by the plurality of insect - inlet channels, due to phototaxis, the female flies will continuously gather towards the top of the transparent top cover, further reducing the risk of escape and greatly improving the trapping efficiency.

[0029] In this embodiment, the base 1 is cylindrical, and the bottom surface of the base 1 is flat. Preferably, there are five insect - inlet channels 3.

[0030] In this embodiment, the transparent top cover 2 is in the shape of a bamboo hat.

[0031] In this embodiment, in order to facilitate female flies to better enter the trap, a plurality of insect - inlet openings 4 are circumferentially and evenly distributed on the circumferential side wall of the transparent top cover 2, and the insect - inlet openings 4 penetrate through the circumferential side wall of the transparent top cover 2. Preferably, there are four insect - inlet openings.

[0032] In this embodiment, each insect inlet 4 is provided with an insect inlet pipe 5. The insect inlet pipe 5 facilitates the entry of female insects into the interior of the trap. The outer end of the insect inlet pipe 5 is clamped at the insect inlet, and the inner end of the insect inlet pipe 5 extends into the transparent top cover 2.

[0033] In this embodiment, in order to reduce the escape of female insects, the insect inlet pipe 5 is in a conical shape with a diameter gradually decreasing from the outside to the inside.

[0034] In this embodiment, as Figure 11 shown, two circles of inner and outer parallel annular protrusions 6 are provided on the outer peripheral side of the outer end of the insect inlet pipe 5. An annular clamping groove 7 for clamping on the peripheral side of the insect inlet 4 is formed between the two circles of annular protrusions 6. When the inner end of the insect inlet pipe is inserted into the insect inlet, the two circles of parallel annular protrusions are clamped on the inner and outer edge walls of the insect inlet.

[0035] In this embodiment, the insect inlet pipe 5 is made of white transparent material.

[0036] In this embodiment, in order to facilitate the hanging of the entire trap, a hanging hook hole 8 is provided at the top of the transparent top cover 2.

[0037] In this embodiment, the inner diameter of the lower port of the transparent top cover 2 is greater than the outer diameter of the top open end of the base 1. The transparent top cover 2 is directly covered on the outside of the top open end of the base 1, and the interior of the transparent top cover 2 is communicated with the interior of the base 1.

[0038] In this embodiment, four horizontal L-shaped clamping grooves 9 are circumferentially and evenly distributed on the lower peripheral side wall of the transparent top cover 2. The L-shaped clamping grooves 9 penetrate through the lower peripheral side wall of the transparent top cover 2; four long strip-shaped clamping protrusions 10 are circumferentially and evenly distributed on the outer peripheral side wall of the upper end of the base 1. The four clamping protrusions 10 correspond to the positions of the four L-shaped clamping grooves 9, and the corresponding clamping protrusions 10 are clamped into the horizontal sections of the L-shaped clamping grooves 9. During operation, when the transparent top cover covers the base, after the clamping protrusions on the base and the L-shaped clamping grooves of the transparent top cover are engaged, the clamping protrusions are rotated into the horizontal sections of the L-shaped clamping grooves.

[0039] Specifically, as Figure 5 shown, the L-shaped clamping groove 9 includes a vertical groove 11 and a horizontal groove 12. The vertical groove 11 extends to the bottom of the transparent top cover 2. The clamping protrusion 10 on the base 2 is first inserted into the vertical groove 11, and then the transparent top cover 2 or the base 1 is rotated to make the clamping protrusion 10 clamped into the horizontal groove 12. Further, an arc-shaped concave portion 13 is provided at one end of the horizontal groove 12 of the L-shaped clamping groove 9. The arc-shaped concave portion 13 is located at one end away from the vertical groove 11; an arc-shaped convex portion 14 for cooperating with the arc-shaped concave portion 13 is provided at the bottom of the clamping protrusion 10.

[0040] In this embodiment, the base 1 is made of yellow opaque material.

[0041] In existing traps, either the base has no insect inlet holes, or if there are any, there is only one large insect inlet hole, allowing the trapped insects to come and go freely, resulting in low trapping efficiency. The bottom of the circular base of the present utility model is a flat surface, and multiple conical convex insect inlet channels are provided at the bottom of the base. The diameter of the conical insect inlet channels gradually decreases from bottom to top. Both the upper and lower ends of the insect inlet channels are open. This design utilizes the biological characteristics of Diptera flies. After the female insects are attracted into the trap through the multiple insect inlet channels of the base, due to phototaxis, the female insects will continuously gather towards the top of the transparent top cover, further reducing the risk of escape and greatly improving the trapping efficiency. At the same time, an insect inlet is provided on the peripheral side wall of the transparent top cover, which also helps to better attract the female insects to enter. The overall design is ingenious, easy to operate, can efficiently trap female flies in the field, improve the prevention and control efficiency, and reduce the risk of female insect escape.

[0042] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (such as using bolts or screws for connection), or it can also be understood as: a non-detachable fixed connection (such as riveting, welding). Of course, the mutually fixed connection can also be replaced by an integral structure (such as being integrally formed by a casting process) (except when it is obviously impossible to adopt the integral forming process).

[0043] In addition, for the terms used to represent the positional relationship or shape in any of the technical solutions disclosed in the present utility model above, unless otherwise stated, their meanings include states or shapes that are approximate, similar, or close to them.

[0044] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.

[0045] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present utility model or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
