Description

Technical Field

[0001] The utility model relates to the technical field of agricultural pest control, in particular to an internal and external double-action fruit fly trapping and killing device. Background Art

[0002] Fruit flies are small insects belonging to the Drosophilidae family of the order Diptera. They feed on saprophytes and fruits. They are highly adaptable, widely distributed, reproduce quickly, and cause great harm. Generally, fruit flies lay eggs on the surface of fruits and hatch them. The hatched larvae drill into the fruits and cause damage, causing the fruits to rot, mold, and fall before harvest. The larvae hidden in the fruits seriously affect the storage effect after harvest. The use of drugs cannot completely kill the adults in the environment, nor can it effectively kill the larvae in the fruits, and pollute the environment and affect the safety of fruits. Although bagging can prevent the harm of fruit flies, it is time-consuming and reduces the quality of fruits, increasing the production cost of agricultural products.

[0003] In order to reduce the damage caused by fruit flies to fruits, growers usually use fruit fly traps to trap and kill adult insects. This method has the advantages of not needing to use fruit fly pesticides for spraying, reducing pesticide usage, saving production costs, and being highly efficient and pollution-free. It is widely used in fruit fly control.

[0004] The inventor has previously designed a fruit fly trap (Chinese utility model patent, authorization announcement number: CN222017544U), including a bottle body and a bottle cap, the bottle body including a fly luring cavity, a trapping hole, a medicine discharge port and a bottom cover, the fly luring cavity is provided with a fly luring agent for attracting fruit flies to drill into the fly luring cavity from the trapping hole, the bottle cap includes a rain guide cover, a mounting cover and a hook, and the bottle body is provided with a connecting cover that matches the mounting cover; the utility model trap is conveniently disassembled and connected through the mounting cover and the connecting cover, and the user can quickly and conveniently add medicine and clean the inside of the trap.

[0005] On the basis of the above device, the inventor further designed a fruit fly trapping device with both internal and external functions, and combined fly paper with the outside of such fruit fly trapping device to achieve the dual trapping effect of both internal and external functions.

Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-3 As shown, a double-acting fruit fly trapping device comprises an umbrella-shaped upper cover 1, a cylindrical part 2, and a cone-shaped lower cover 4 which are detachably connected from top to bottom. The cylindrical part 2 is provided with a fly inlet 21, and a fly attractant is contained in the cylindrical part 2. A positioning baffle 22 is arranged around the cylindrical part 2, and a gap is provided between the positioning baffle 22 and the outer wall of the cylindrical part 2 for a fly paper 3 to extend into; the fly paper 3 comprises a smooth part 31 positioned between the positioning baffle 22 and the outer wall of the cylindrical part 2, and a sticky part 32 which is sleeved on the outer periphery of the cylindrical part 2 and exposed to the air.

[0030] The above design enables the fruit fly trapping device to have both internal and external functions. Fly attractants and toxic liquid medicine are placed in the cylindrical part to attract fruit flies to enter the cylindrical part from the fly entrance 21 and be poisoned. At the same time, when the lured fruit flies do not enter the cylindrical part from the fly entrance 21, the fly paper 3 outside the cylindrical part will stick to the fruit flies, and the fly paper can be detachably connected between the positioning baffle 22 and the outer wall of the cylindrical part 2 to facilitate timely replacement. When it is necessary to clean the inside of the cylindrical part, just open the upper cover or the lower cover.

[0031] Specifically, in this embodiment, the positioning baffle 22 is disposed at the upper and lower ends of the cylindrical portion 2, and a mounting opening 221 is provided on the positioning baffle 22. The fly paper 3 has a smooth portion 31 located at the upper and lower ends thereof and a sticky portion 32 located between the upper and lower ends. The smooth portion 31 extends from the mounting opening 221 into between the positioning baffle 22 and the outer wall of the cylindrical portion 2, so that the fly paper 3 is sleeved on the outer wall of the cylindrical portion 2 and the sticky portion 32 is exposed. This design allows the fly paper 3 to be installed or removed from the mounting opening 221, which is convenient for immediate replacement of the fly paper on the fruit fly trapping device.

[0032] The fly paper 3 comprises a smooth surface facing the outer wall of the cylindrical portion 2 and a functional surface exposed to the air for catching flies. According to research and experiments conducted by the inventor, blue has a better effect on attracting fruit flies than other colors, so the functional surface has a blue layer.

[0033] The upper cover 1 also has a hook 11 and an umbrella-shaped portion 12, the diameter of the umbrella-shaped portion 12 is not less than the diameter of the cylindrical portion 2; the hook is used to hang the trapping device, and the umbrella-shaped portion plays a shielding role to prevent rain or dust from entering, thereby extending the use time of the device.

[0034] In this embodiment, the upper cover 1 is threadedly connected to the cylindrical portion 2 via an upper cover connecting portion 13; the upper cover 1 is connected to a bait rack 14 for placing fly attractants at a position below the umbrella-shaped portion 12. When the upper cover 1 is connected to the cylindrical portion 2, the bait rack 14 is located inside the cylindrical portion 2. The bait rack is used to hold bait with a strong odor, and insecticide liquid is held below the bait rack 14 in the cylindrical portion to kill fruit flies that enter the cylindrical portion.

[0035] like Figure 4 As shown, the hook 11 extends to the bottom of the umbrella-shaped portion 12, and the bait rack 14 is connected to the lower end of the hook 11, and the bait rack 14 has an arc-shaped support box 141 for containing fly attractants. When the upper cover 1 is opened, it is convenient to take out the arc-shaped support box 141 containing fly attractants together; arc-shaped blocks 23 are arranged at intervals at the opening of the upper end of the cylindrical portion 2, and arc-shaped grooves are formed between the arc-shaped blocks 23 for the arc-shaped support box 141 to pass through and enter the cylindrical portion 2. This design makes it possible for the arc-shaped support box 141 to be put into or taken out of the cylindrical portion 2 only at a specific position, so that it is not easy to slip out of the cylindrical portion 2.

[0036] like Figure 5 As shown, the inner wall of the cylindrical portion 2 is protruded with an annular support block 24 for supporting the arc-shaped support box 141; the annular support block supports and positions the arc-shaped support box so that it can be placed stably.

[0037] Finally, the lower cover connecting part 41 is hinged to the hinge seat 25 at the lower end of the cylindrical part 2 through a torsion spring and a hinge shaft, and a sealing ring is arranged at the cooperation position between the lower cover 4 and the cylindrical part 2; when it is necessary to pour out the liquid medicine, only the lower cover 4 can be opened, and a sealing ring is arranged between the lower cover and the cylindrical part 2, and the torsion spring ensures that the lower cover and the cylindrical part maintain a sealed cooperation to prevent the liquid medicine from leaking out.

[0038] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
