Drosophila melanogaster trap

Abstract

The utility model relates to the technical field of fruit fly trapping, and discloses a spot wing fruit fly trapper which comprises a cylindrical outer cylinder, a conical inner cylinder is installed at the upper end of the interior of the cylindrical outer cylinder in an embedded mode and comprises an inner cylinder shell and a cover plate located at the upper end of the inner cylinder shell, an opening-shaped inlet is formed in the bottom end of the inner cylinder shell, and the opening-shaped inlet is communicated with the cylindrical outer cylinder. And an opening-shaped outlet is formed in the top end of the inner barrel shell. The attractant box is arranged on the lower portion of the open outer barrel shell and the open inner barrel shell, meanwhile, the gaps are formed between the outer barrel shell and the base plate and between the outlet and the cover plate, when the spotted wing drosophila flies falling on the base plate take off upwards due to habits, the spotted wing drosophila flies directly enter the inner barrel shell from the inlet and then fly out of the outlet, and therefore the spotted wing drosophila flies are prevented from falling into the base plate. When the spot-wing drosophila melanogaster traps, the spot-wing drosophila melanogaster enters a space structure among the inner barrel shell, the outer barrel shell and the cover plate, and due to the fact that the inner diameter of the outlet is small and the spot-wing drosophila melanogaster likes the upward take-off habit, the spot-wing drosophila melanogaster hardly has the possibility of reverse escape, and the purpose of efficient trapping can be achieved.

Description

TECHNICAL FIELD

[0001] The utility model relates to fruit fly trapping technical field, concretely is a kind of spotted wing drosophila trapper. BACKGROUND

[0002] Spotted wing drosophila belongs to diptera, and it is a kind of dangerous pest that harms raspberry, blueberry, cherry and other soft-skinned fruits. It has the characteristics of fast transmission, wide range and damage to mature or submature fruits. The whole larval stage feeds on fruits, making it difficult to control. This pest has caused serious damage to the fruit industry in many countries around the world.

[0003] Due to the lack of understanding of spotted wing drosophila among fruit farmers, most of them control it as fruit flies. The main control methods are chemical control and physical control. Physical control is mainly through trapper. The trapper mainly uses noctuidae trapper and fruit fly trapper instead, resulting in many deficiencies in trapping effect. For example, the hole of noctuidae trapper is large, and spotted wing drosophila is small, so it is easy to escape. The pest entry of fruit fly trapper is generally set from top to bottom. Due to the habit of spotted wing drosophila, it likes to fly upwards, resulting in low trapping amount and poor effect. For example, a spotted wing drosophila trapper (authorized publication number CN219323101U) is disclosed in Chinese patent. In this patent technology, spotted wing drosophila enters the trapper body from the mesh of the insect entry under the action of the attractant in the plastic bottle body, and then flies to the plastic bottle body to be killed by the insecticide. Or spotted wing drosophila flies to the trapper top cover to lay eggs under the action of the red trapper top cover, and is killed by the insecticide smeared on the trapper top cover. However, it does not consider the habit of spotted wing drosophila, resulting in low trapping amount and poor effect. UTILITY MODEL CONTENT

[0004] The utility model aims to provide a kind of spotted wing drosophila trapper to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] The utility model discloses a lure box is arranged in the lower part of the outer barrel shell and the inner barrel shell of opening shape, and the space structure of collecting spatulata flies is formed between the inner barrel shell, the outer barrel shell and the cover plate, when the spatulata flies falling on the bottom disc take off upward due to the habit, directly enter the inner barrel shell from the import, and then fly out from the export and enter the space structure between the inner barrel shell, the outer barrel shell and the cover plate, because the inner diameter of the export is small, and the spatulata flies like taking off upward, so the possibility of reverse escape of the spatulata flies is almost nonexistent, thereby the purpose of high -efficient trapping can be realized.

DETAILED DESCRIPTION

[0018] Please refer to Figs. 1-4 The utility model discloses an example of a kind of Drosophila suzukii trap, including cylindrical outer tube 1, the upper end of the inside of cylindrical outer tube 1 is embedded and installed conical inner tube 2.

[0019] In Fig. 3 , cylindrical outer tube 1 includes outer tube shell 11, and the bottom disc 13 at the lower end of outer tube shell 11, the middle part of the upper end of bottom disc 13 is provided with attractant box 14, attractant for attracting Drosophila suzukii is added in attractant box 14, and the smell emitted by attractant attracts Drosophila suzukii;Outer tube shell 11 and bottom disc 13 are fixedly connected by a plurality of support rods 12, and a certain gap can be formed between outer tube shell 11 and bottom disc 13 by support rod 12, to facilitate Drosophila suzukii to fly into inner tube shell 21.

[0020] In Fig. 4 , conical inner tube 2 includes inner tube shell 21, and the cover plate 25 at the upper end of inner tube shell 21, the bottom end of inner tube shell 21 is provided with the entrance 22 of opening type, and the top end of inner tube shell 21 is provided with the exit 23 of opening type, and the cover plate 25 is fixedly connected between inner tube shell 21 and cover plate 25 by a plurality of connecting rods 24, and a certain gap can be formed between exit 23 and cover plate 25 by connecting rod 24, to facilitate Drosophila suzukii to fly out from inner tube shell 21;The upper end of the middle part of cover plate 25 is fixedly connected with hanging ring 26, and the whole trap can be hung in the forest through hanging ring 26.

[0021] In Fig. 3 and Fig. 4 , the upper end of the inner side wall of outer tube shell 11 is provided with internal thread groove 15, the lower end of the outer side wall of cover plate 25 is provided with cover plate 25, and cover plate 25 and outer tube shell 11 are fixedly connected through external thread groove 27 and internal thread groove 15, so that cover plate 25 and outer tube shell 11 can be disassembled conveniently.

[0022] In Fig. 3 and Fig. 4 , the inside of outer tube shell 11 is cylindrical, the outside of inner tube shell 21 is conical, and the outer diameter of the bottom of inner tube shell 21 is the same as the inner diameter of outer tube shell 11, so that the space structure for collecting Drosophila suzukii is formed between inner tube shell 21, outer tube shell 11 and cover plate 25.

[0023] Preferably, cover plate 25 and inner tube shell 21 are both components of transparent structure, and light transmission can be realized through transparent structure, so as to guide Drosophila suzukii to fly in the direction of light, and improve trapping effect.

[0024] The working principle of the utility model is: firstly, the attractant for attracting Bactrocera parviceps is added in the attractant box 14; then, the whole trap is hung in the forest through the hanging ring 26;

[0025] The Bactrocera parviceps is attracted by the smell of the attractant in the attractant box 14 and falls on the base plate 13; since the Bactrocera parviceps has the habit of flying upward, when the Bactrocera parviceps flies, it will directly enter the inner cylinder shell 21 from the inlet 22, then fly out from the outlet 23 upward, enter the space structure between the inner cylinder shell 21, the outer cylinder shell 11 and the cover plate 25, since the inner diameter of the outlet 23 is small and the Bactrocera parviceps has the habit of flying upward, therefore, the Bactrocera parviceps almost has no possibility of escaping reversely, so that the trapping purpose can be achieved.

[0026] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
