Description

Technical Field

[0001] The utility model belongs to the technical field of terrestrial snails feeding inducement, and in particular relates to a Pomacea canaliculata feeding inducement and screening device. Background Art

[0002] Pomacea canaliculata Pomacea canaliculata ), also known as the big bottle snail and apple snail, is an amphibious freshwater snail belonging to the family of bottle snails in the order of gastropoda of the phylum Mollusca. The snail has strong reproductive capacity, omnivorous diet, large appetite, strong resistance to adversity, rapid spread, and wide distribution. It is a global quarantine pest snail, causing serious damage to agricultural production and ecosystems in invaded areas. At the same time, the golden apple snail is also an important intermediate host of the zoonotic parasite 'Guangzhou roundworm' (infection rate is as high as 7.6%), which can cause eosinophilic meningitis in humans.

[0003] For a long time, the prevention and control of golden apple snails has mainly relied on manual snail picking and chemical snailicides. Manual snail picking is inconvenient, time-consuming, labor-intensive, and inefficient. Chemical snailicides not only cause harm to other organisms and the environment, but also lead to frequent phenomena of "treating the symptoms but not the root cause" and "repeated control but not stopping". Therefore, it is urgent to develop efficient and environmentally friendly golden apple snail attractants. The key prerequisite for the development of attractants is to screen attractant materials. The screening process must have an optimized attractant screening device that matches the living habits of golden apple snails. However, up to now, there is no effective attractant screening device. Therefore, it is urgent to design a golden apple snail attractant test device to screen attractant materials in a targeted manner and provide reliable basic data for the development of attractants.

DETAILED DESCRIPTION

[0024] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply 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 understood as a limitation on the present invention.

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 and 2 As shown, a device for attracting and screening golden apple snails comprises a snail box 1 and a plurality of trapping units 2. Each trapping unit 2 is provided with an attracting material for attracting the golden apple snails to move into the inner cavity of the trapping unit 2. Each trapping unit 2 is provided with a connecting pipe 3 connected to the snail box 1, so that the golden apple snails in the snail box 1 eventually crawl into the trapping box 2-1 through the attraction of the smell.

[0027] like Figure 2 As shown, the trapping unit 2 includes a trapping box 2-1 and a bait box. The bait box is arranged in the trapping box 2-1 for containing the attractant material. The trapping box 2-1 is a box body with the box opening facing upward. A cover 2-4 is arranged at the box opening of the trapping box 2-1 for sealing the box opening. During the comparative experiment, the experimenter replaces the attractant material in the trapping box 2-1 by opening or closing the cover 2-4 of the box opening. In this embodiment, the length, width and height of the trapping box 2-1 are 19.0 cm, 19.0 cm and 11.5 cm respectively. Furthermore, a 3.0 cm water layer is contained at the bottom of the trapping box 2-1.

[0028] like Figure 2As shown, air supply port 2-5 and trapping inlet 2-6 are respectively provided on two opposite sides of the trapping box 2-1. The diameters of the air supply port 2-5 and the trapping inlet 2-6 are both 5 cm. Among them, the trapping inlet 2-6 is connected to the snail box 1 through the connecting pipe 3. In this embodiment, one end of the connecting pipe 3 is fixed at the trapping inlet by a thread. The inner and outer diameters of the connecting pipe 3 are 4.5 cm and 5.0 cm respectively, and the length is 10 cm. The height from the axis of the connecting pipe 3 to the bottom 2-1 of the trapping box is 7.2 cm.

[0029] In this embodiment, nylon mesh is sealed at the air outlet 2-5 and the upper edge of the trapping entrance 2-6. The nylon mesh is used to prevent the golden apple snails entering the trapping box 2-1 from escaping from the air outlet 2-5. At the same time, it can prevent the golden apple snails entering the trapping box 2-1 from returning to the snail box 1 or escaping to other trapping boxes 2-1 from the trapping entrance 2-6, thereby affecting the experimental results.

[0030] Specifically, when the golden apple snail enters the trapping box 2-1 from the outer end of the trapping entrance 2-6, the nylon mesh is gradually lifted by the golden apple snail. When the golden apple snail completely enters the trapping box 2-1, the nylon mesh automatically droops under the action of gravity, shielding the trapping entrance 2-6 to prevent the golden apple snail entering the trapping box 2-1 from escaping from the trapping entrance 2-6.

[0031] Furthermore, a mini fan 4 is provided outside the trapping box 2-1 and in front of the air outlet 2-5, which is used to drive the smell in the trapping box 2-1 to be output from the trapping inlet 2-6 to the connecting pipe and then to the snail box, so as to attract the snails in the snail box 1 to move into the trapping box 2-1.

[0032] In this embodiment, the bait box is a concave dish 2-3, which is fixed to the center of the bottom surface of the trapping box 2-1 through a bottom support 2-2. The concave dish 2-3 is used to place the placement area of ​​the attractant material. In this embodiment, the diameter of the concave dish 2-3 is 10.0 cm and the height is 3.0 cm.

[0033] Furthermore, there are four trapping units 2. The connecting pipes 3 on the four trapping units 2 are connected to the collection inlet 1-1 through a three-dimensional five-way pipe 5. Figure 1 and 3 As shown, the five ports of the three-dimensional five-way pipe 5 are divided into four convergence inlets 5-1 and a convergence outlet 5-2 connected to the inner cavity of the screw box 1. Four connecting pipes 3 are respectively nested at the four convergence inlets.

[0034] In this embodiment, the inner and outer diameters of the converging outlet 5-2 and each converging inlet 5-1 of the three-dimensional five-way pipe 5 are 5.0 cm and 5.5 cm respectively. The pipe height at the converging outlet is 7.2 cm, and the distance between the two opposite converging inlets is 10.0 cm.

[0035] like Figure 2 As shown, the cover of the snail box 1 is provided with a collection inlet 1-1 matched with a convergence outlet 5-2. The diameter of the collection inlet 1-1 is 5.5 cm. When in use, the connecting pipe 3 is connected to the collection inlet 1-1 through the three-dimensional five-way pipe 5. The golden apple snails in the snail box 1 gradually enter the trapping box 2-1 through the connecting pipe 3.

[0036] In this embodiment, the length, width and height of the snail box 1 are 21.0 cm, 15.0 cm and 8.5 cm respectively.

[0037] The principle of screening the food attractant material for Pomacea canaliculata in the utility model is as follows:

[0038] Assemble the snail box 1 and four trapping boxes 2-1 through the connecting tube 3, and inject a 3.0 cm water layer along the inner wall of the trapping box 2-1. Inject a 3.0 cm water layer into the snail box 1. During the test, place a food attractant to be tested in the concave dish 2-3 of each trapping box 2-1, and place 30 golden apple snails of the same size and starved for one day in the snail box 1. Turn on the power and drive the mini fan 4. Through the air flow, the smell of food attractants will drift from the trapping box 2-1 to the snail box 1 through the connecting tube 3. After starting the food attractant test, observe and record the number of golden apple snails attracted in each group every 4 hours. Repeat the above operation 3 times, take the average value of each test, and compare the degree of attraction of different food attractants to golden apple snails.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
