Problems solved by technology

Disadvantages: Chemical agents are highly toxic, easily leave crops and water bodies, and pollute the environment
Disadvantages: Using this mode requires certain breeding conditions and facilities, and ducks may also cause some damage to crop seedlings such as trampling and pecking
Disadvantages: high labor cost and low efficiency
Moreover, if the egg masses in the above-mentioned device are not removed in time, the newly hatched young snails will fall into the field and regenerate a generation

Embodiment Construction

[0024] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.

[0025] refer to Figure 1 to Figure 3

[0026] An egg-laying apple snail capture device includes a flat plate 10, the surface of which is sprayed with a plant-smelling material layer 11, so as to better attract the egg-laying apple snails to climb up the flat plate. Cylindrical traps 20 are respectively arranged on the flat surfaces on both sides of the top of the flat plate, and the utilization rate is improved by a pair of transparent tubular traps. The cylindrical trap is made of transparent material for better light transmission. The upper end of the cylindrical trapping cage is provided with a transparent fence-shaped top plate 21, and the lower end of the cylindrical trapping cage is horizontally equippe...

Abstract

The invention relates to a spawning ampullaria gigas trapping device and method. The device comprises a flat insertion plate. A material layer with plant aroma is sprayed on the surface of the flat insertion plate. Cylindrical trapping cages are arranged on the flat faces of the two sides of the upper portion of the flat insertion plate respectively. The upper end of each cylindrical trapping cageis provided with a transparent fence-shaped top plate. The lower end of each cylindrical trapping cage is transversely provided with a fence-shaped one-way door which can only be opened upward and isautomatically closed under the effect of gravity. The fence distance between each fence-shaped top plate and the corresponding fence-shaped one-way door is 5-10 mm. The spawning ampullaria gigas trapping device is simple in structure, spawning ampullaria gigas is trapped through a physical method, and the use method is simple.

Description

technical field [0001] The invention relates to a device and method for catching apple snails that lay eggs. Background technique [0002] The golden apple snail belongs to the genus Plasmidae of the family Gastropodidae in the mollusk phylum, and was introduced into mainland my country in 1981. Because the snail has a wide range of food, large food intake, strong adaptability, and fast growth and reproduction, it is flooded in most Asian countries, seriously endangering aquatic crops such as rice and xerophyte crops near water areas, resulting in severe crop production reduction or even failure. It is an extremely serious agricultural pest and has been listed as one of the invasive alien species in my country. In addition, apple snails are also the host of Angiostrongylus cantonensis, a zoonotic parasitic disease. Eating insufficiently heated apple snails may cause parasites such as Angiostrongylus cantonensis to infect the human body, which can cause diseases such as meni...
